Commit 8116188fde ("nouveau/acpi: hook up to the MXM method for mux

dependency on MXM and MXM being an x86 platform driver.
It built previously since the vga switcheroo registration routines were
zereod out on !X86. The code was built in but unused.
This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO,
allowing it to build on non-x86 and shrinking the module size as well.

Since an old pageflip will keep its scanout buffer object pinned until
it has executed its unpin task on the common workqueue, we can clog up
our GGTT with stale pinned objects. As we cannot flush those workqueues
without dropping our locks, we have to resort to falling back to
userspace and telling them to repeat the operation in order to have a
chance to run our workqueues and free up the required memory. If we
fail, then we are forced to report ENOSPC back to userspace causing the
operation to fail and best-case scenario is that it introduces temporary
corruption.

On older generations (gen2, gen3) the GPU requires fences for many
operations, such as blits. The display hardware also requires fences for
scanouts and this leads to a situation where an arbitrary number of
fences may be pinned by old scanouts following a pageflip but before we
have executed the unpin workqueue. This is unpredictable by userspace
and leads to random EDEADLK when submitting an otherwise benign
execbuffer. However, we can detect when we have an outstanding flip and
so cause userspace to wait upon their completion before finally
declaring that the system is starved of fences. This is really no worse
than forcing the GPU to stall waiting for older execbuffer to retire and
release their fences before we can reallocate them for the next
execbuffer.

Atm after a failed link training we disable the DP port. This can happen
during a modeset-enable or a DP link re-establishment. The latter can be
a problem and we shouldn't disable the DP port, see the previous patch for
the reasoning. In the former case the right thing would be to disable
the DP port, but also the rest of the pipe.
As a stop-gap solution leave the DP port enabled in both cases. It is an

Currently if the DP link is lost (either because of a hot unplug, or

of the pipe running. This is incompatible with the modeset disabling
sequence of some platforms/configurations. At least this is the case for
DP ports on the CPU as opposed to PCH.
Atm we'll also get a warning when we do a modeset disable after the
above link lost event, since we expect the DP port to be enabled at this
point (see the bugzilla ticket for the related dmesg).
Note that with this patch we'll still end up disabling the port, thanks
to the HPD uevent and subsequent modeset disable.

call i915_gem_object_free which needs to deref obj->base.dev to get at

allocation can easily fail when userspace is hitting open file limits.
Doing the structure init even when the shmem file allocation fails
prevents this Oops.

On pre-PCH platforms ISR doesn't seem to be an actual ISR, at least as
far as display interrupts are concerned. Instead it sort of looks like
some ISR bits just directly reflect the corresponding bit from PIPESTAT.
The bit appears in the ISR only if the PIPESTAT interrupt is enabled. So
in that sense it sort of looks a bit like the south interrupt scheme on
PCH platforms. So it goes something a bit like this:
PIPESTAT.status & PIPESTAT.enable -> ISR -> IMR -> IIR -> IER -> actual
interrupt
In any case that means the intel_pipe_in_vblank_locked() doesn't actually
work for pre-PCH platforms. As a last resort, add a similar kludge as radeon
has that fixes things up if we got called from the vblank interrupt,
but the scanline counter value indicates that we're not quite there yet.
We know that the scanline counter increments at hsync but is otherwise
accurate, so we can limit the kludge to the line just prior to vblank
start, instead of the relative distance that radeon uses.

Also the current code doesn't handle interlaced modes correctly,
and we already deal with interlaced modes in i915 code.
So let's just move the current code to radeon_get_crtc_scanoutpos()

Since commit 61b365a505 ("drm/nouveau: populate master subdev pointer
only when fully constructed"), the nouveau_mxm(bios) call will return
NULL, since it's still being called from the constructor. Instead, pass
the mxm pointer via the unused data field.

Pull request of 2014-01-17
Pull request for 3.14. One not so urgent fix, One huge device update.
The pull request corresponds to the patches sent out on dri-devel, except:
[PATCH 02/33], review tag typo pointed out by Matt Turner.
[PATCH 04/33], dropped. The new surface formats are never used.
The upcoming vmware svga2 hardware version 11 will introduce the concept
of "guest backed objects" or -resources. The device will in principle
get all
of its memory from the guest, which has big advantages from the device
point of view.
This means that vmwgfx contexts, shaders and surfaces need to be backed
by guest memory in the form of buffer objects called MOBs, presumably
short for MemoryOBjects, which are bound to the device in a special way.
This patch series introduces guest backed object support. Some new IOCTLs
are added to allocate these new guest backed object, and to optionally
provide
them with a backing MOB.
There is an update to the gallium driver that comes with this update, and
it will be pushed in the near timeframe presumably to a separate mesa branch
before merged to master.

Anyway, nothing big here, Three more code cleanup patches from Rashika
Kheria, and one TTM/vmwgfx patch from me that tightens security around TTM
objects enough for them to opened using prime objects from render nodes:
Previously any client could access a shared buffer using the "name", also
without actually opening it. Now a reference is required, and for render nodes
such a reference is intended to only be obtainable using a prime fd.

Disabling the hotplug IRQ is a two-step process. First, inside the IRQ

we would never need this patch, but since we do allow modeset for
disconnected connectors we may see user space trying to set modes on

that.

Looks like 830M doesn't quite like it when you try to move a plane from

drm/i915: Swap primary planes on gen2 for FBC
caused a regression on 830M. It will attempt to swap the planes when the
driver is loaded, but at that time only pipe A might be active, so plane
A gets disabled, but plane B won't get enabled since pipe B is not
active when we try to move the plane over to pipe A.
There's no reason to swap planes on 830M since it doesn't support
FBC. Change the logic a bit to limit the plane swapping to platforms
which actually support FBC. This should avoid getting a black screen on

When the pipe A force quirk is applied the code will attempt to grab
a crtc mutex during intel_modeset_setup_hw_state(). If we're already
holding all crtc mutexes this will obviously deadlock every time.
So instead of using drm_modeset_lock_all() just grab the
mode_config.mutex. This is enough to avoid the unlocked mutex warnings
from certain lower level functions.

Add support for the new MDP5 display controller block. The mapping
between parts of the display controller and KMS is:
plane -> PIPE{RGBn,VIGn} \
crtc -> LM (layer mixer) |-> MDP "device"
encoder -> INTF /
connector -> HDMI/DSI/eDP/etc --> other device(s)
Unlike MDP4, it appears we can get by with a single encoder, rather
than needing a different implementation for DTV, DSI, etc. (Ie. the
register interface is same, just different bases.)
Also unlike MDP4, all the IRQs for other blocks (HDMI, DSI, etc) are
routed through MDP.
And finally, MDP5 has this "Shared Memory Pool" (called "SMP"), from
which blocks need to be allocated to the active pipes based on fetch
stride.

The HDMI block is basically the same between older SoC's with mdp4
display controller, and newer ones with mdp5.
So mostly this consists of better abstracting out the different sets of
regulators, clks, etc. In particular, for regulators and clks we can
split it up by what is needed for hot plug detect to work, and what is
needed to light up the display.
Also, 8x74 has a new phy.. a very simple one, but split out into a
different mmio space. And with mdp5, the irq is shared with mdp, so we
don't directly register our own irq handler.

Add a VRAM carveout that is used for systems which do not have an IOMMU.
The VRAM carveout uses CMA. The arch code must setup a CMA pool for the
device (preferrably in highmem.. a 256m-512m VRAM pool in lowmem is not
cool). The user can configure the VRAM pool size using msm.vram module
param.
Technically, the abstraction of IOMMU behind msm_mmu is not strictly
needed, but it simplifies the GEM code a bit, and will be useful later
when I add support for a2xx devices with GPUMMU, so I decided to keep
this part.
It appears to be possible to configure the GPU to restrict access to
addresses within the VRAM pool, but this is not done yet. So for now
the GPU will refuse to load if there is no sort of mmu. Once address
based limits are supported and tested to confirm that we aren't giving
the GPU access to arbitrary memory, this restriction can be lifted

The current dev_unload order uninits the irqs too early.
In the current sequence, it's possible that a crtc queues work(apply_worker)
to display a buffer, which registers to omap_crtc_apply_irq to notfiy the
completion of the configuration we applied.
Calling drm_vblank_cleanup and omap_drm_irq_uninstall here causes the crtc's
apply handler to never get called, which results in an incorrect state of the
apply_irq.registered parameter.
This condition occurs where there is no mode set via omapdrm, and dev_lastclose
tries to set a default fb mode via drm_fb_helper_restore_fbdev_mode. The apply
work scheduled by restore_fbdev_mode is very close in time to the disabling of
the irq handler, and hence leads to a race condition. We move the irq cleanup
at the end of the unload sequence to prevent this.
Also, the call to flush_workqueue is removed since it's called internally by
destroy_workqueue.

Currently, an encoder is disabled only when an apply work is queued for the
corresponding crtc. This works fine for the paths where userspace explicitly
disables crtc, this results in disabling the omapdss device in the crtc's
pre_apply function.
However, when the omapdrm module is removed, there is no work queued to ensure
that the encoder is disabled. This can result in an enabled omapdss device when
removing omapdrm. omapdss is left in an inconsistent state, and that prevents us
from using that omapdss device being used again.
Disable enabled encoders in omap_encoder_destroy, we could consider a better
place for doing this later.

At omapdrm probe, we install manager ops and connect omapdss devices. This
needs to be undone when omapdrm module is removed so that omapdss is in a
clean state. This ensures that we can re-insert omapdrm module, or some other
module which uses omapdss(like omapfb/omap_vout).
Currently, omapdrm's remove neither uninstalls manager ops, or disconnects
omapdss devices. We make sure that this is done in pdev_remove.
omapdrm establishes connections for omap_dss_device devices when probed. It
should also be responsible to disconnect the devices. Keeping the devices
connected can prevent the panel driver modules from unloading, it also causes
issues when we try to remove or re-insert omapdrm module.

With the omapdss device model changes. omapdrm is required to call dssdriver's
connect() op to register a panel. This is currently done in omap_modeset_init()
A call to connect() can fail if the omapdss panels or the encoders(HDMI/DPI)
they connect to have some resource(like regulators, I2C adapter) missing. If
this happens, the correct approach is to defer omapdrm's probe.
omapdrm currently ignores those panels which return a non zero value when
connected. This could result in omapdrm ignoring all panels on an omap board.
The right approach would be for omapdrm to request for probe deferral when a
panel's connect op returns -EPROBE_DEFER.
In order to do this, we need to call connect() much earlier during omapdrm's
probe to prevent too many things are already done by then. We now connect the
panels during pdev_probe(), before anything else is initialized, so that we
don't need to undo too many things if a defer was requested.
Now when we enter omap_modeset_init(), we have a set of panels that have been
connected. We now proceed with registering only those panels that are already
connected.
A special case has to be considered when no panels are available to connect when
omapdrm probes. In this case too, we defer probe and expect that a panel will be
available to connect the next time.
Checking whether the panel has a driver or whether it has get_timing/read_edid
ops in omap_modeset_init() are redundant with the new display model. These can
be removed since a dssdev device will always have a driver associated with it,
and all dssdev drivers have a get_timings op.
This will mainly fix cases when omapdrm is built-in the kernel, since that's
generally where resources like regulators or I2C are unavailable because of
probe order dependencies.
In particular this fixes boot with omapdrm built-in on an omap4 panda ES board.
The regulators used by HDMI(provided by I2C based TWL regulators) aren't
initialized because I2C isn't initialized, I2C isn't initialized as it's pins
are not configured because pinctrl is yet to probe.

(OMAPDSS: DISPC: set irq_safe for runtime PM), which makes dispc's
runtime calls irq-safe.
However, using pm_runtime_irq_safe in dispc makes the parent of dispc,
dss, always enabled, effectively preventing PM for the whole DSS module.
This patch makes omapdrm behave better by adding new irq (un)register
functions that do not use dispc_runtime_get/put, and using those
functions in interrupt context. Thus we can make dispc again
non-irq-safe, allowing proper PM.

LPT does have PCH refclk, but it's different form the IBX/CPT/PPT one
and doesn't use the same structs. It is wrong to have a message saying
that "LPT does not has PCH refclk" (sic). While at it, signal that we
only want this function on IBX/CPT/PPT by renaming it and adding a
WARN.
On HSW we also print "0 shared PLLs initialized", but we *do* have
shared PLLs on HSW (LCPLL, WRPLL, SPLL) and we *do* initialize them.
We just don't use "struct intel_shared_dpll". So remove the debug
message.
In the future we may want to rename all that "intel shared pll" code
to "ibx shared pll", but I'll leave this to another patch.

When a client looks up a ttm object, don't look it up through the device hash
table, but rather from the file hash table. That makes sure that the client
has indeed put a reference on the object, or in gem terms, has opened
the object; either using prime or using the global "name".
To avoid a performance loss, make sure the file hash table entries can be
looked up from under an RCU lock, and as a consequence, replace the rwlock
with a spinlock, since we never need to take it in read mode only anymore.
Finally add a ttm object lookup function for the device hash table, that is
intended to be used when we put a ref object on a base object or, in gem terms,
when we open the object.

This is illegal for at least two reasons:
1) While it may work on some platforms / iommus, obtaining page pointers from
mapped sg-lists is illegal, since the DMA API allows page pointer information
to be destroyed in the sg mapping process.
2) TTM has no way of determining the linear kernel map caching state of the
underlying pages. PTEs with conflicting caching state pointing to the same
pfn is not allowed.
TTM operations touching pages of imported sg-tables should be redirected through
the proper dma-buf operations.

offset have BMP version 2.01 or 5.01 or higher. So instead of looking at the
bios major version, look at the BMP version. BIOSes with BMP version 0
do not contain a detectable script, so always return 0 for them.

In very rare cases (such as a memory failure stress test) it is possible
to fill the entire ring without emitting a request. Under this
circumstance, the outstanding request is flushed and waited upon. After
space on the ring is cleared, we return to emitting the new command -
except that we just cleared the seqno allocated for this operation and
trigger the sanity check that a request is only ever emitted with a
valid seqno. The fix is to rearrange the code to make sure the
allocation of the seqno for this operation is after any required flushes
of outstanding operations.
The bug exists since the preallocation was introduced in
