da00bdcfb2 drm/i915: Remove the magic AUX_CTL is at DP + foo tricks
Currently we determine the location of the AUX registers in a confusing
way. First we assume the PCH registers are used always, but then we
override it for everything but HSW/BDW to use DP+0x10. Very confusing.

Let's just make it straightforward and simply add a few functions to
pick the right AUX_CTL based on the DP port.

To deal with VLV/CHV we'll include the display_mmio_offset into the
AUX register defines.

a121f4e5fa drm/i915: Replace the aux ddc name switch statement with kasprintf()
Use kasprintf() to generate the "DPDDC-<port>" name for the aux helper.

To deal with errors properly make intel_dp_aux_init() return something,
and adjust the caller to match. It seems we were also missing a
intel_dp_mst_encoder_cleanup() call on edp (non-port A) init failures,
so add that too.

The whole error/cleanup ordering doesn't feel entirely sane to me, but
I'll leave that part alone for now.

500a3d2eb3 drm/i915: Fix GT frequency rounding
When we set and later readback a frequency value through
sysfs interface, igt/pm_rpm assumes that we get same value back
if it matches hw granularity.

On bxt we have found out that this is not always the case.
Currently frequency - hw ratio - frequency conversions round down,
with few exceptions on platforms that have more specific conversions.
On bxt the supported range can be for example from 100Mhz to 650Mhz.
Midpoint is then calculated by test to be 375 which pm_rps uses to find a
closest hw supported frequency. That is 366 (ratio 22),
which it then writes back. But as the rounding down kicks in,
driver actually sets 350 instead of 366, as 366 is 2/3 below 22 * 50/3.

Fix this by rounding to closest instead of rounding down in
freq-ratio-freq conversions.

0c545ac481 drm: Don't oops in drm_calc_timestamping_constants() if drm_vblank_init() wasn't called
Seems the crtc helpers call drm_calc_timestamping_constants()
unconditionally even if the driver didn't initialize vblank support by
calling drm_vblank_init(). That used to be OK since the constants were
stored under drm_crtc.

However I broke this with
commit eba1f35dfe ("drm: Move timestamping constants into drm_vblank_crtc")
when I moved the constants to live inside the drm_vblank_crtc struct
instead. If drm_vblank_init() isn't called, we don't allocate these
structures, and so drm_calc_timestamping_constants() will oops.

Fix it by adding a check into drm_calc_timestamping_constants() to see
if vblank support was initialized at all. And to keep in line with other
such checks, also toss in a check and warn for the case where vblank
support was initialized, but the wrong number of crtcs was specified.

Fixes the following sort of oops:

f514c2d842 drm/i915/gen9: flush DMC fw loading work during system suspend
Currently during system s/r we enable/disable DC6, so before we do so
make sure that the firmware loading is complete.

Note that whether we need to enable DC6 for S3/S4 is still open.  At
least the firmware program is lost during S3 and we need to reprogram it
after resuming. Until this is clarified we keep the current behavior and
enable/disable DC6.

During driver unload to ensure we dont have any pending task,
flush_work added to complete firmware loading task.

v1: Initial version.

v2: As per review comments from Daniel,
Removed flush_work from skl_set_power_well. As we have taken
power well refernece and rpm count during firmware loading
by using display_power_domain_get/put - this will always
ensure rpm will be blocked if firmware is not loaded.

Two benefits:
- We can use FW_LOADER_USERSPACE_FALLBACK.
- We can use flush_work to synchronize with the oustanding worker,
  which is a notch more obvious what it does than having a special
  completion.

The next patch will properly synchronize against the async loader in
the resume and unload code.

414b7999b8 drm/i915/gen9: Remove csr.state, csr_lock and related code.
This removes two anti-patterns:
- Locking shouldn't be used to synchronize with async work (of any
  form, whether callbacks, workers or other threads). This is what the
  mutex_lock/unlock seems to have been for in intel_csr_load_program.
  Instead ordering should be ensured with the generic
  wait_for_completion()/complete(). Or more specific functions
  provided by the core kernel like e.g.
  flush_work()/cancel_work_sync() in the case of synchronizing with a
  work item.

- Don't invent own completion like the following code did with the
  (already removed) wait_for(csr_load_status_get()) pattern - it's
  really hard to get these right when you want them to be _really_
  correct (and be fast) in all cases. Furthermore it's easier to read
  code using the well-known primitives than new ones using
  non-standard names.

Before enabling/disabling DC6 check if the firmware is loaded
successfully. This is guaranteed during runtime s/r, since otherwise we
don't enable RPM, but not during system s/r.

Note that it's still unclear whether we need to enable/disable DC6
during system s/r, until that's clarified, keep the current behavior and
enable/disable DC6.

Also after this patch there is a race during system s/r where the
firmware may not be loaded yet, that's addressed in an upcoming patch.

01a6908c0c drm/i915: use correct power domain for csr loading
Grabbing a runtime pm reference with intel_runtime_pm_get will only
prevent device D3. But dmc firmware is required even earlier (namely
for the skl power well 2).

Hence we need to grab a rpm reference higher up in the hierarchy. For
simplicity just grab the _INIT display power well. That's a bit too
much, but since the firmware loading task should completely fairly
quickly this won't be a real problem really.

ebae38d061 drm/i915/gen9: csr_init after runtime pm enable
Skl is fully dependent on dmc for going to low power state (dc5/dc6).
This requires a trigger from rpm. To ensure the dmc firmware
is available for runtime pm support rpm-reference-count is used
by not releasing the rpm reference if firmware loading is
not completed.

So moved the intel_csr_ucode_init call after runtime pm enable.

e00bf69644 drm/i915: Move the fbdev async_schedule() into intel_fbdev.c
Reading the driver load/unload code leaves one confused as there's
an async_schedule() in the load, but not async_synchronize_full()
in sight. In fact it's hidden inside intel_fbdev.c. So let's move the
async_schedule() into intel_fbdev.c as well so that it's next to the
async_synchronize_full(), which should make the relationship easier
to see.

Plus this way we won't schedule a nop function call when fbdev is
disabled. And we were passing a pointer to a static inline
function to async_schedule(), which seems rather dubious to me.

2013bfc023 drm/i915: Do fbdev fini first during unload
We set up fbdev last during load, so doing the fbdev cleanup should be
first.

We weren't supposed to drop the init power during driver unload, but since
the fbdev teardown happened after intel_power_domains_fini() that could
have happened due in one of two ways. First it could have happened
during the modeset caused by normal fbdev cleanup. But in addition it
could have happened already via the intel_fbdev_initial_config() since
that is executed asynhronously, and the async_synchronize_full() was
done during fbdev cleanup, after intel_power_domains_fini(). All of
that got eliminated by
commit 292b990e86 ("drm/i915: Update power domains on readout.")
since we now drop the init power synchronously during driver load.

So there is no real bug wrt. the init power anymore, but still it seems
better to do the fbdev cleanup first, before we've potentially cleaned
up something else important.

18a04a7369 drm/i915: Kill intel_runtime_pm_disable()
intel_runtime_pm_disable() takes an extra rpm reference which combined
with the one we leak from intel_display_set_init_power() leaves the
usage count at <original>+1 after the driver has been unloaded.
The original ref is dropped explicitly in intel_runtime_pm_enable().
So the next time we load the driver we can no longer do runtime PM ever.

This used to work, but
commit 292b990e86 ("drm/i915: Update power domains on readout.")
broke things by not dropping the init power domain during fbdev
teardown. Based on the comment in intel_power_domains_fini(), the
way it used to to work wasn't intentional. As in we weren't supposed
to drop the init power during driver unload. And since we no longer
do, we now leak an extra rpm reference.

So fix things by throwing intel_runtime_pm_disable() to the bin, so
that the only leaked reference comes from the init power domain.

 "Two build fixes, one for VC4, one for nouveau where the ARM only code
  is doing something a bit strange.  While people are discussing that,
  just workaround it and fix the build for now.  The code in question
  will never get used on anything non-ARM anyways.

  Also one fix for AST that SuSE had been hiding in their kernel, that
  allows all fbdev apps to work on that driver"

10855aeb1e drm/nouveau: fix build failures on all non ARM.
gk20a is an ARM only GPU, so we can just do the correct thing on
ARM but fail on other architectures. The other option was to use
SWIOTLB as the define, which means phys_to_page exists, but
this seems clearer.

28fb4cb7fa drm/ast: Initialized data needed to map fbdev memory
Due to a missing initialization there was no way to map fbdev memory.
Thus for example using the Xserver with the fbdev driver failed.
This fix adds initialization for fix.smem_start and fix.smem_len
in the fb_info structure, which fixes this problem.

6fec766283 drm/i915: Use intel_dp->DP in eDP PLL setup
Use intel_dp->DP in the eDP PLL setup, instead of doing RMWs.

To do this we need to move DP_AUDIO_OUTPUT_ENABLE setup to happen later,
so that we don't enable audio accidentally while configuring the PLL.

Note that actually we already enabled audio before the port due to
the double port register write magic required by VLV/CHV from
7b713f50d7 ("drm/i915: Fix eDP link training when switching pipes on VLV/CHV")
So that gets changed now to keep audio off as long as the port is off.

Also intel_dp_link_down() must be made to update intel_dp->DP so that we
don't re-enable the port by accident when turning off the PLL. This is
safe now that we don't call intel_dp_link_down() during link retraining.

v2: Add a note about the audio vs. port enable (Daniel)

d6fbdd157c drm/i915: Hide underruns from eDP PLL and port enable on ILK
We get underruns on the other pipe when enabling the CPU eDP PLL and
port on ILK.

Bspec knows about the PLL issue, and recommends doing a vblank wait just
prior to enabling the PLL. That does seem to help, but unfortunately we
get another underrun when actually enabling the CPU eDP port. Bspec
doesn't mention that at all, and the same vblank wait trick doesn't
appear to be effective there.

Since I have no better clue how to deal with this, just hide the errors.

0c241d5b27 drm/i915: Disable FIFO underrun reporting around IBX transcoder B workaround
Doing the IBX transcoder B workaround causes underruns on
pipe/transcoder A. Just hide them by disabling underrun reporting for
pipe A around the workaround.

It might be possible to avoid the underruns by moving the workaround
to be applied only when enabling pipe A. But I was too lazy to try it
right now, and the current method has been proven to work, so didn't
want to change it too hastily.

Note that this can re-enable underrun reporting on pipe A if was
already disabled due to a previous actual underrun. But that's OK, we
may just get a second underrun report if another real underron occurrs
on pipe A.

v2: Note that pipe A underruns can get re-enabled due to this (Jani)

81b088ca87 drm/i915: Re-enable PCH FIO underrun reporting after pipe has been disabled
Some hardware (IVB/HSW and CPT/PPT) have a shared error interrupt for
all the relevant underrun bits, so in order to keep the error interrupt
enabled, we need to have underrun reporting enabled on all PCH
transocders. Currently we leave the underrun reporting disabled when
the pipe is off, which means we won't get any underrun interrupts
when only a subset of the pipes are active.

Fix the problem by re-enabling the underrun reporting after the pipe has
been disabled. And to avoid the spurious underruns during pipe enable,
disable the underrun reporting before embarking on the pipe enable
sequence. So this way we have the error reporting disabled while
running through the modeset sequence.

I've left out the vblank wait before the enable here because I don't

5205bbe62b drm/i915: remove in_dbg_master check from intel_fbc.c
From our maintainer Daniel Vetter a few days ago:
  "Oh dear this is dead code. kdbg uses the fbcon, which always uses
  untiled, which means fbc will never be enabled. Also we have 0 users
  and 0 test coverage for kdbg on top of i915 (Jesse implemented it
  for fun years back). Imo just remove all this code."

Adding to what Daniel said: for kgdboc's KMS support,
intel_pipe_set_base_atomic() already manually disables FBC, so we
won't do the in_dbg_master() check there. This is essentially a revert
of:

    i915: when kgdb is active display compression should be off

Besides, it is not clear what is the exact problem caused by FBC, and
why other features such as PSR, DRRS, IPS and RPM are not also
checking for in_dbg_master(). IMHO we should either remove the code as
suggested by Daniel or we add some nice comments explaining why is FBC
so special.

v2: Rebase due to new patch order.

Make sure we deactivate FBC at intel_fbc_init(), so we can remove the

we'll add assertions to them, so just calling intel_fbc_disable() from
intel_modeset_init() won't work. It's better to make sure
intel_fbc_init() already puts the hardware in the expected state, so
we can put nice assertions in the other functions.

548043abae drm/i915: fix the __intel_fbc_update() comments
Don't try to list in comments the cases where we should enable or
disable FBC: it varies a lot with the hardware generations and the
code should be the documentation. Also notice that there's already a
huge gap between the comments and what's in the code.

45b32a2919 drm/i915: use struct intel_crtc *crtc at __intel_fbc_update()
This change was part of the commit that makes intel_fbc_update()
receive an intel_crtc as argument instead of dev_priv, but since it
was polluting the diff with too many chunks I decided to move it to
its own commit.

It seems that our developers are favoring having this instead of the
old combination drm_crtc *crtc + intel_crtc *intel_crtc, and on the
mentioned commit we'll get rid of the drm_crtc variable, so let's do
an intermediate commit with the rename, so on the next commit we'll
have just struct intel_crtc *crtc.

6c566dc9ac drm/i915/bxt: Force port A DDI to use 4 lanes
The bspec indicates that DDI A using four lanes is the only valid
configuration for Broxton (Broxton doesn't have a DDI E to split these
lanes with); the DDI_A_4_LANES bit of port A's DDI_BUF_CTL should always
be set by the BIOS.  However some BIOS versions seem to only be setting
this bit if eDP is actually lit up at boot time; if the BIOS doesn't
turn on the eDP panel because an external display is plugged in, then
this bit is never properly initialized.  The end result of this is that
we wind up calculating a lower max data rate than we should and may wind
up rejecting the native mode for panels that we should be able to drive.

Let's workaround this BIOS bug by just turning the DDI_A_4_LANES bit on
in our driver's internal state if we recognize that we're running on BXT
where it should have been on anyway.

51f1385b90 drm/i915: Fix failure paths around initial fbdev allocation
We had two failure modes here:

1.
Deadlock in intelfb_alloc failure path where it calls
drm_framebuffer_remove, which grabs the struct mutex and intelfb_create
(caller of intelfb_alloc) was already holding it.

2.
Deadlock in intelfb_create failure path where it calls
drm_framebuffer_unreference, which grabs the struct mutex and
intelfb_create was already holding it.

[Daniel Vetter on why struct_mutex needs to be locked in the second half
of intelfb_create: "The vma [for the fbdev] is pinned, the problem is
that we re-lookup it a few times, which is racy. We should instead track
the vma directly, but oh well we don't."]

v2:
   * Reformat commit msg to 72 chars. (Lukas Wunner)
   * Add third failure mode. (Lukas Wunner)

v5:
   * Rebase on drm-intel-nightly 2015y-09m-01d-09h-06m-08s UTC,
     rephrase commit message. (Jani Nicula)

v6:
   * In intelfb_alloc, if __intel_framebuffer_create failed,
     fb will be an ERR_PTR, thus not null. So in the failure
     path we need to check for IS_ERR_OR_NULL to avoid calling
     drm_framebuffer_remove on the ERR_PTR. (Lukas Wunner)
   * Since this is init code a drm_framebuffer_unreference should
     be all we need. drm_framebuffer_remove is for framebuffers
     that userspace has created - and is getting somewhat
     defeatured. (Daniel Vetter)

v7:
   * Clarify why struct_mutex needs to be locked in the second half
     of intelfb_create. (Daniel Vetter)

dcb1394e74 drm/i915: On fb alloc failure, unref gem object where it gets refed
Currently when allocating a framebuffer fails, the gem object gets
unrefed at the bottom of the call stack in __intel_framebuffer_create,
not where it gets refed, which is in intel_framebuffer_create_for_mode
(via i915_gem_alloc_object) and in intel_user_framebuffer_create
(via drm_gem_object_lookup).

This invites mistakes: __intel_framebuffer_create is also called from
intelfb_alloc, and as discovered by Tvrtko Ursulin, a double unref
was introduced there with a8bb681827 ("drm/i915: Fix error path leak
in fbdev fb allocation").

As suggested by Ville Syrjälä, fix the double unref and improve code
clarity by moving the unref away from __intel_framebuffer_create to
where the gem object gets refed.

Based on Tvrtko Ursulin's original v2.

v3: On fb alloc failure, unref gem object where it gets refed,
    fix double unref in separate commit (Ville Syrjälä)

v4: Lock struct_mutex on unref (Chris Wilson)

v5: Rebase on drm-intel-nightly 2015y-09m-01d-09h-06m-08s UTC,

2e01fabe67 signals: kill block_all_signals() and unblock_all_signals()
It is hardly possible to enumerate all problems with block_all_signals()
and unblock_all_signals().  Just for example,

1. block_all_signals(SIGSTOP/etc) simply can't help if the caller is
   multithreaded. Another thread can dequeue the signal and force the
   group stop.

2. Even is the caller is single-threaded, it will "stop" anyway. It
   will not sleep, but it will spin in kernel space until SIGCONT or
   SIGKILL.

And a lot more. In short, this interface doesn't work at all, at least
the last 10+ years.

Daniel said:

  Yeah the only times I played around with the DRM_LOCK stuff was when
  old drivers accidentally deadlocked - my impression is that the entire
  DRM_LOCK thing was never really tested properly ;-) Hence I'm all for
  purging where this leaks out of the drm subsystem.

c62d25556b mm, fs: introduce mapping_gfp_constraint()
There are many places which use mapping_gfp_mask to restrict a more
generic gfp mask which would be used for allocations which are not
directly related to the page cache but they are performed in the same
context.

Let's introduce a helper function which makes the restriction explicit and
easier to track.  This patch doesn't introduce any functional changes.

71baba4b92 mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM
__GFP_WAIT was used to signal that the caller was in atomic context and
could not sleep.  Now it is possible to distinguish between true atomic
context and callers that are not willing to sleep.  The latter should
clear __GFP_DIRECT_RECLAIM so kswapd will still wake.  As clearing
__GFP_WAIT behaves differently, there is a risk that people will clear the
wrong flags.  This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly
indicate what it does -- setting it allows all reclaim activity, clearing
them prevents it.

d0164adc89 mm, page_alloc: distinguish between being unable to sleep, unwilling to sleep and avoiding waking kswapd
__GFP_WAIT has been used to identify atomic context in callers that hold
spinlocks or are in interrupts.  They are expected to be high priority and
have access one of two watermarks lower than "min" which can be referred
to as the "atomic reserve".  __GFP_HIGH users get access to the first
lower watermark and can be called the "high priority reserve".

Over time, callers had a requirement to not block when fallback options
were available.  Some have abused __GFP_WAIT leading to a situation where
an optimisitic allocation with a fallback option can access atomic
reserves.

This patch uses __GFP_ATOMIC to identify callers that are truely atomic,
cannot sleep and have no alternative.  High priority users continue to use
__GFP_HIGH.  __GFP_DIRECT_RECLAIM identifies callers that can sleep and
are willing to enter direct reclaim.  __GFP_KSWAPD_RECLAIM to identify
callers that want to wake kswapd for background reclaim.  __GFP_WAIT is
redefined as a caller that is willing to enter direct reclaim and wake
kswapd for background reclaim.

This patch then converts a number of sites

o __GFP_ATOMIC is used by callers that are high priority and have memory
  pools for those requests. GFP_ATOMIC uses this flag.

o Callers that have a limited mempool to guarantee forward progress clear
  __GFP_DIRECT_RECLAIM but keep __GFP_KSWAPD_RECLAIM. bio allocations fall
  into this category where kswapd will still be woken but atomic reserves
  are not used as there is a one-entry mempool to guarantee progress.

o Callers that are checking if they are non-blocking should use the
  helper gfpflags_allow_blocking() where possible. This is because
  checking for __GFP_WAIT as was done historically now can trigger false
  positives. Some exceptions like dm-crypt.c exist where the code intent
  is clearer if __GFP_DIRECT_RECLAIM is used instead of the helper due to
  flag manipulations.

o Callers that built their own GFP flags instead of starting with GFP_KERNEL
  and friends now also need to specify __GFP_KSWAPD_RECLAIM.

The first key hazard to watch out for is callers that removed __GFP_WAIT
and was depending on access to atomic reserves for inconspicuous reasons.
In some cases it may be appropriate for them to use __GFP_HIGH.

The second key hazard is callers that assembled their own combination of
GFP flags instead of starting with something like GFP_KERNEL.  They may
now wish to specify __GFP_KSWAPD_RECLAIM.  It's almost certainly harmless
if it's missed in most cases as other activity will wake kswapd.

0280d1a099 sound updates for 4.4-rc1
Here is the first batch of updates for sound system on 4.4-rc1.
 Again at this time, the update looks fairly calm; no big changes in
 either ALSA core or ASoC infrastructures, rather all small cleanups,
 in addition to the new stuff as usual.
 
 The biggest changes are about Firewire sound devices.  It gained lots
 of new device support, and MIDI functionality.  Also there are updates
 for a few still working-in-progress stuff (topology API and ASoC
 skylake), too.  But overall, this update should give no big surprise.
 
 Some highlight is below:
 
 Core:
  - A few more Kconfig items for tinification; it's marked as EXPERT,
    so normal user should't be bothered :)
  - Refactoring with a new PCM hw_constraint helper
  - Removal of unused transfer_ack_{begin,end} PCM callbacks
 
 Firewire:
  - Restructuring of code subtree, lots of refactoring
  - Support AMDTP variants
  - New driver for Digidesign 002/003 family
  - Adds support for TASCAM FireOne to ALSA OXFW driver
  - Add MIDI support to TASCAM and Digi00x devices
 
 HD-Audio:
  - Automated modalias generation for codec drivers, finally
  - Improvement on heuristics for setting mixer name
  - A few fixes for longstanding bugs on Creative CA0132 cards
  - Addition of audio rate callback with i915 communication
  - Fix suspend issue on recent Dell XPS
  - Intel Lewisburg controller support
 
 ASoC:
  - Updates to the topology userspace interface
  - Big updates to the Renesas support (rcar)
  - More updates for supporting Intel Sky Lake systems
  - New drivers for Asahi Kasei Microdevices AK4613, Allwinnner A10,
    Cirrus Logic WM8998, Dialog DA7219, Nuvoton NAU8825, Rockchip
    S/PDIF, and Atmel class D amplifier
 
 USB-Audio:
  - A fix for newer Roland MIDI devices
  - Quirks and workarounds for Zoom R16/24 device
 
 Misc:
  - A few fixes for some old Cirrus CS46xx PCI sound boards
  - Yet another fixes for some old ESS Maestro3 PCI sound boards

1b0e3a049e drm/i915/skl: disable display side power well support for now
The display power well support on this platform is in a somewhat broken
state atm, so disable it by default.

This in effect will get rid of incorrect assert WARNs about the CSR/DMC
firmware not being loaded during power well toggling. It also removes a
problem during driver loading where a register is accessed while its
backing power well is down, resulting in another WARN. Until we come up
with the root cause of the second problem and the proper fix for both
issues, keep all display side power wells on.

Also clarify a bit the option description.

99106bc17e drm/i915: Do graphics device reset under forcewake
We have a timed release of a forcewake when using
I915_READ/WRITE macros. wait_for() macro will go to quite
long sleep if the first read doesn't satisfy the condition for
successful exit. With these two interacting, it is possible that
we lose the forcewake during the wait_for() and the subsequent read
will reaquire forcewake.

Further experiments with skl shows that when we lose forcewake,
we lose the reset request we submitted. So reset request register
is not power context saved.

Grab forcewakes for all engines before starting the reset/request
dance so that all requests stay valid for the duration of reset
requisition across all the engines.

v2: Add comment on power well sleeps. Wrap the reset handling
    under forcewake instead of just reset requests (Chris)

f1b391a551 drm/i915/skl: While sanitizing cdclock check the SWF18 as well
SWF18 is set if the display has been initialized by the pre-os. It also
gives what configuration is enabled on which pipe. In skl_sanitize_cdclk,
the DPLL sanity check can pass even if GOP/VBIOS is not loaded as BIOS
enables DPLL for integrated audio codec related programming.
So fisrt check if SWF18 is set and then follow through with other DPLL
and CDCLK verification. If not set then for sure we need to sanitize the
cdclock.

v2: Update the commit message for clarity (Siva)
v3: Correct the mask to check for bits[23:0] instead of only bits[16:0].
    Had missed checking for PIPE C altogether. Remaining are reserved (Siva)
v4: Use ILK_SWF macro for SWF register definitions. Taken from Ville's patch

9807216f58 drm/i915: Skip fence installation for objects with rotated views (v4)
While pinning a fb object to the display plane, only install a fence
if the object is using a normal view. This corresponds with the
behavior found in i915_gem_object_do_pin() where the fencability
criteria is determined only for objects with normal views.

v2:
Look at the object's map_and_fenceable flag to determine whether to
install a fence or not (Chris).

v3:
Pin and unpin a fence only if the current view type is normal.

v4:
Extend the "view type is normal" check for pin_fence as well.

b566762796 drm/i915/bxt: Fix eDP panel fitting (v2)
BXT CRTC scaling uses the same gen9 codepaths as SKL; these codepaths
store panel fitter information in pipe_config->pch_pfit.  However since
HAS_PCH_SPLIT() is false for BXT we never actually wind up filling in
this structure (we wind up filling in pipe_config->gmch_pfit instead,
which is ignored when we go to program the hardware).  Make sure we
always take the PCH code path on gen9+ platforms.

v2: Use HAS_GMCH_DISPLAY() to more cleanly describe the platforms that
    actually want to use GMCH-style panel fitting.  (Ville)

I wanted to add yet another check to intel_fbc_update() and realized

remembered this patch series that Damien wrote a long time ago and
nobody ever reviewed, so I decided to reimplement it since the code
changed a lot since then.

bf248ca1f5 drm/i915: Fix locking around GuC firmware load

but this collides badly with request_firmware. Move struct_mutex
locking down into the loader itself, so we don't hold it across the
entire load process, including request_firmware.

The way to load the HQVDP firmware has been updated.
HQVDP firmware is now loaded the first time an HQVDP plane is used and
no more when the HQVDP driver is bound.
This solves the dependency we had on the file system availability.
The first time the HQVDP plane is used, we are sure that file system is
available so request_firmware function will match.

CONFIG_FW_LOADER_USER_HELPER_FALLBACK is then no more mandatory.

78eaf335e4 drm/nouveau/pll/gk104: fix PLL instability due to bad configuration with gddr5
This patch uses an approach closer to the nvidia driver to configure
both PLLs for high gddr5 memory clocks (usually above 2400MHz)

Previously nouveau used the one PLL as it was used for the lower clocks
and just adjusted the second PLL to get as close as possible to the
requested clock.  This means for my card, that I got a 4050 MHz clock
although 4008 MHz was requested.

Now the driver iterates over a list of PLL configuration also used by
the nvidia driver and then adjust the second PLL to get near the
requested clock.  Also it hold to some restriction I found while
analyzing the PLL configurations

This won't fix all gddr5 high clock issues itself, but it should be
fine on hybrid gpu systems as found on many laptops these days.  Also
switching while normal desktop usage should be a lot more stable than
before.

v2: move the pll code into ramgk104

5d5b43f59b drm/nouveau/pci: Handle 5-bit and 8-bit tag field
If the hardware supports extended tag field (8-bit ones), then enable it.

This is usually done by the VBIOS, but not on some MBPs (see fdo#86537).

In case extended tag field is not supported, 5-bit tag field is used which
limits the possible number of requests to 32. Apparently bits 7:0 of
0x08841c stores some number of outstanding requests, so cap it to 32 if
extended tag is unsupported.

Fixes: fdo#86537

  * Add nvkm_pci_mask to pci.h
  * Mask bit 8 before setting it

69c4938249 drm/nouveau/instmem/gk20a: use direct CPU access
The Great Nouveau Refactoring Take II brought us a lot of goodness,
including acquire/release methods that are called before and after an
instobj is modified. These functions can be used as synchronization
points to manage CPU/GPU coherency if we modify an instobj using the
CPU.

This patch replaces the legacy and slow PRAMIN access for gk20a instmem
with CPU mappings and writes. A LRU list is used to unmap unused
mappings after a certain threshold (currently 1MB) of mapped instobjs is
reached. This allows mappings to be reused most of the time.

Accessing instobjs using the CPU requires to maintain the GPU L2 cache,
which we do in the acquire/release functions. This triggers a lot of L2
flushes/invalidates, but most of them are performed on an empty cache
(and thus return immediately), and overall context setup performance
greatly benefits from this (from 250ms to 160ms on Jetson TK1 for a
simple libdrm program).

Making L2 management more explicit should allow us to grab some more
performance in the future.

04b8a4bd8e drm/nouveau/gem: return only valid domain when there's only one
On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.

This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

2bcdcbfae2 drm/tegra: dc: Request/free syncpoint at init/exit
syncpoints are resources provided by host1x and their lifetime is tied
to the host1x device. They are not properly reference counted either, so
removing the host1x device before any of its clients causes a use-after-
free error. Adding proper reference counting would be a major enterprise
so work around it for now by requesting and freeing the syncpoint at
init and exit time, respectively. The host1x device is guaranteed to be
around at this point.

ef11bdb3e0 drm/i915/kbl: Introduce Kabylake platform defition.
Kabylake is a Intel® Processor containing Intel® HD Graphics
following Skylake.

It is Gen9p5, so it inherits everything from Skylake.

Let's start by adding the platform separated from Skylake
but reusing most of all features, functions etc. Later we
rebase the PCI-ID patch without is_skylake=1
so we don't replace what original Author did there.

Few IS_SKYLAKEs if statements are not being covered by this patch
on purpose:
   - Workarounds: Kabylake is derivated from Skylake H0 so no
     		  W/As apply here.
   - GuC: A following patch removes Kabylake support with an
     	  explanation: No firmware available yet.
   - DMC/CSR: Done in a separated patch since we need to be carefull
     	      and load the version for revision 7 since
	      Kabylake is Skylake H0.

608c1a526c drm/i915: Recover all available ringbuffer space following reset
Having flushed all requests from all queues, we know that all
ringbuffers must now be empty. However, since we do not reclaim
all space when retiring the request (to prevent HEADs colliding
with rapid ringbuffer wraparound) the amount of available space
on each ringbuffer upon reset is less than when we start. Do one
more pass over all the ringbuffers to reset the available space

4018169704 drm/i915: Read FORCEWAKE registers with I915_READ_FW()
Change FORCEWAKE & co. reads for the error state to use I915_READ_FW().
Reading a FORCEWAKE register using a function that can frob forcewake
just seems wrong.

There is a check to skip grabbing the forcewake for accessing FORCEWAKE
in intel_uncore.c, but there's no such check for FORCEWAKE_MT. So no
idea what is currently happening with FORCEWAKE_MT reads. FORCEWAKE_VLV
is fortunately outside the forcewake range anyway, so no actual issue
with that one.

So let's just make the rule that you can't access FORCEWAKE registers with
the normal I915_READ() stuff, and we can drop the extra FORCEWAKE check
from NEEDS_FORCEWAKE(). While at it use NEEDS_FORCEWAKE() on BDW, where
it was skipped for whatever bikeshed reason that I've already forgotten.

75aa3f6307 drm/i915: Turn __raw_i915_read8() & co. in to inline functions
There's no need for __raw_i915_read8() & co. to be macros, so make them
inline functions. To avoid typo mistakes generate the inline functions
using preprocessor templates.

We have a few users of the raw register acces functions outside
intel_uncore.c, so let's also move the functions into intel_drv.h.

While doing that switch I915_READ_FW() & co. to use the
__raw_i915_read() functions, and use the _FW macros everywhere
outside intel_uncore.c where we want to read registers without
grabbing forcewake and whatnot. The only exception is
i915_check_vgpu() which itself gets called from intel_uncore.c,
so using the __raw_i915_read stuff there seems appropriate.

v2: Squash in the intel_uncore.c->i915_drv.h move
    Convert I915_READ_FW() to use __raw_i915_read(), and use
    I915_READ_FW() outside of intel_uncore.c (Chris)

Struct of gem object in exynos_drm driver is struct exynos_drm_gem_obj.
It's too long and we can know its meaning of name without _obj postfix.

We use several names to variable name of gem object for exynos_drm -
exynos_gem_obj, gem_obj and obj. Especially "obj" name can cause
misunderstanding with variable name "obj" of struct drm_gem_object.

This will clean about name of gem object for exynos_drm as follows.

s/exynos_gem_obj or gem_obj or obj/exynos_gem

The drm_release_iommu_mapping() is a function to release mapping of

9c8e1bdb95 drm/i915: Cope with request list state change during error state capture
Since we're not synchronizing the ring request list during error state capture
the request list state might change between the time the corresponding error
request list was allocated and dimensioned to the time when the ring request
list is actually captured into the error state. If this happens then do an
early exit and be aware that the captured error state might not be fully
reliable.

* v2:
- Chris Wilson: Removed WARN_ON from size check since having the error state
  request list and the live driver request list diverge like this is a
  legitimate behaviour.

- Tomas Elf: Removed update of num_request field since this made no sense. Just
  exit and move on.

* v3:
- Chris Wilson: Removed error message at the point of early exit. The user is
  not interested in any state changes happening during the error state capture,
  only in the state that we're trying to capture at the point of the error.

97e5ed1111 drm/i915: shut up gen8+ SDE irq dmesg noise
We get tons of cases where the master interrupt handler apparently set
a bit, with the SDEIIR disagreeing. No idea what's going on there, but
it's consistent on gen8+, no one seems to care about it and it's
making CI results flaky.

Shut it up.

No idea what's going on here, but we've had fun with PCH interrupts
before:

Note that there's a regression report in Bugzilla, and other

8e2930c6cf drm/msm/mdp: Add Software Pixel Extension support
In order to produce an image, the scalar needs to be fed extra
pixels. These top/bottom/left/right values depend on a various of
factors, including resolution, scaling type, phase step and
initial phase.

Pixel Extension are programmed by hardware in most targets - and
can be overwritten by software. For some targets (e.g.: msm8996),
software *must* program those registers.

In order to ease this computation, let's always use bilinear
filters, which are easier to program from kernel. Eventually,
all of these values will come down from user space for better
quality.

2a6c521bb4 drm/nouveau/gem: return only valid domain when there's only one
On nv50+, we restrict the valid domains to just the one where the buffer
was originally created. However after the buffer is evicted to system
memory, we might move it back to a different domain that was not
originally valid. When sharing the buffer and retrieving its GEM_INFO
data, we still want the domain that will be valid for this buffer in a
pushbuf, not the one where it currently happens to be.

This resolves fdo#92504 and several others. These are due to suspend
evicting all buffers, making it more likely that they temporarily end up
in the wrong place.

86c8bbbeb8 drm/i915: Calculate ILK-style watermarks during atomic check (v3)
Calculate pipe watermarks during atomic calculation phase, based on the
contents of the atomic transaction's state structure.  We still program
the watermarks at the same time we did before, but the computation now
happens much earlier.

While this patch isn't too exciting by itself, it paves the way for
future patches.  The eventual goal (which will be realized in future
patches in this series) is to calculate multiple sets up watermark
values up front, and then program them at different times (pre- vs
post-vblank) on the platforms that need a two-step watermark update.

While we're at it, s/intel_compute_pipe_wm/ilk_compute_pipe_wm/ since
this function only applies to ILK-style watermarks and we have a
completely different function for SKL-style watermarks.

Note that the original code had a memcmp() in ilk_update_wm() to avoid
calling ilk_program_watermarks() if the watermarks hadn't changed.  This
memcmp vanishes here, which means we may do some unnecessary result
generation and merging in cases where watermarks didn't change, but the
lower-level function ilk_write_wm_values already makes sure that we
don't actually try to program the watermark registers again.

v2: Squash a few commits from the original series together; no longer
    leave pre-calculated wm's in a separate temporary structure since
    it's easier to follow the logic if we just cut over to using the
    pre-calculated values directly.

v3:
 - Pass intel_crtc instead of drm_crtc to .compute_pipe_wm() entrypoint
   and use intel_atomic_get_crtc_state() to avoid need for extra
   casting.  (Ander)
 - Drop unused intel_check_crtc() function prototype.  (Ander)

791a32be6e drm/i915: Drop intel_update_sprite_watermarks
The only platform that still has an update_sprite_wm entrypoint is SKL;
on SKL, intel_update_sprite_watermarks just updates intel_plane->wm and
then performs a regular watermark update.  However intel_plane->wm is
only used to update a couple fields in intel_wm_config, and those fields
are never used by the SKL code, so on SKL an update_sprite_wm is
effectively identical to an update_wm call.  Since we're already
ensuring that the regular intel_update_wm is called any time we'd try to
call intel_update_sprite_watermarks, the whole call is redundant and can
be dropped.

09dc1387c9 drm/vmwgfx: Stabilize the command buffer submission code
This commit addresses some stability problems with the command buffer
submission code recently introduced:

1) Make the vmw_cmdbuf_man_process() function handle reruns internally to
avoid losing interrupts if the caller forgets to rerun on -EAGAIN.
2) Handle default command buffer allocations using inline command buffers.
This avoids rare allocation deadlocks.
3) In case of command buffer errors we might lose fence submissions.
Therefore send a new fence after each command buffer error. This will help
avoid lengthy fence waits.

090425c45d drm: rcar-du: Add support for the R8A7794 DU
The R8A7794 DU has a fixed output routing configuration with one RGB
output per CRTC and thus lacks the RGB output routing register field.

feda33ef0f drm/i915/guc: Add GuC css header parser
The size / offset information of all firmware ingredients are
now caculated from header. Driver will validate the header and
rsa key size. If any component is out of boundary, driver will
reject the loading too.

v6: Clean up warnings from make docs

v5: Tidy up GuC titles in kernel/Doc

v4: Now using 'size_dw' for those defined in css_header

v3: 1) Move DOC to intel_guc_fwif.h right before css_header
definition. Add more comments.
    2) Change 'size' to 'len' or 'length' to avoid confusion.
    3) Add UOS_RSA_SCRATCH_MAX_COUNT according to BSpec. And
driver validate size of RSA key now.
    4) Add fw component size/offset info to intel_guc_fw.

v2: Add indent into DOC to make fixed-width format rather than
change the tmpl.

v1: 1) guc_css_header is defined as __packed now
    2) Add and correct GuC related topics in kernel/Doc
