8fb6e528c3 drm/amdgpu: increase IH ring buffer size to avoid overflow

inline with other asics.

92c177b794 drm/radeon/dp_auxch: Ratelimit aux transfer debug messages
Aux transfers always fail with non-zero status flags when there's
nothing connected on the port, so we don't usually need to see all of
the debugging information from it. Also, we try reprobing a -lot-, so
without ratelimiting most of the kernel log is filled up with messages
from radeon_dp_aux_transfer_native.

In some cases, manually insmod/rmmod amdgpu is necessary. When
unloading amdgpu, the KIQ IRQ enable/disable function will case
system hang. The root cause is, in the sequence of function
amdgpu_fini, the sw_fini of IP block AMD_IP_BLOCK_TYPE_GFX will be
invoked earlier than that of AMD_IP_BLOCK_TYPE_IH. So continue to use
the variable freed by AMD_IP_BLOCK_TYPE_GFX will cause system hang.

59c66c911f drm/amdgpu: simplify reservation handling during buffer creation
By using ttm_bo_init_reserved instead of the manual initialization of
the reservation object, the reservation lock will be properly unlocked
and destroyed when the TTM BO initialization fails.

Actual deadlocks caused by the missing unlock should have been fixed
by "drm/ttm: never add BO that failed to validate to the LRU list",
superseding the flawed fix in commit 38fc4856ad ("drm/amdgpu: fix
a potential deadlock in amdgpu_bo_create_restricted()").

This change fixes remaining recursive locking errors that can be seen
with lock debugging enabled, and avoids the error of freeing a locked
mutex.

As an additional minor bonus, buffers created with resv == NULL and
the AMDGPU_GEM_CREATE_VRAM_CLEARED flag are now only added to the
global LRU list after the fill commands have been issued.

v2: use amdgpu_bo_unreserve instead of ttm_bo_unreserve

c2c139cf43 drm/ttm: never add BO that failed to validate to the LRU list
Fixes a potential race condition in amdgpu that looks as follows:

Task 1: attempt ttm_bo_init, but ttm_bo_validate fails
Task 1: add BO to global list anyway
Task 2: grabs hold of the BO, waits on its reservation lock
Task 1: releases its reference of the BO; never gives up the
        reservation lock

The patch "drm/amdgpu: fix a potential deadlock in
amdgpu_bo_create_restricted()" attempts to fix that by releasing
the reservation lock in amdgpu code; unfortunately, it introduces
a use-after-free when this race _doesn't_ happen.

This patch should fix the race properly by never adding the BO
to the global list in the first place.

34bb2734d1 drm/amd/amdgpu: add power profile sysfs entry
Add the sysfs entries pp_gfx_power_profile and
pp_compute_power_profile which give user a way to set
power profile through parameters minimum sclk, minimum mclk,
activity threshold, up hysteresis and down hysteresis only
when the entry power_dpm_force_performance_level is in
default value "auto". It is read and write. Example:

echo 500 800 20 0 5 > /sys/class/drm/card0/device/pp_*_power_profile

cat /sys/class/drm/card0/device/pp_*_power_profile
500 800 20 0 5

Note: first parameter is sclk in MHz, second is mclk in MHz,
third is activity threshold in percentage, fourth is up hysteresis
in ms and fifth is down hysteresis in ms.

echo set > /sys/class/drm/card0/device/pp_*_power_profile
To set power profile state if it exists.

echo reset > /sys/class/drm/card0/device/pp_*_power_profile
To restore default state and clear previous setting.

this is for SRIOV fix:

original scheme that hw_init allocates MQD.

because if hw_init allocates MQD, then resume will

8bcad07a45 drm/i915/gvt: fix error return check for copy_gma_to_hva()
From commit 73dec95e6b ("drm/i915: Emit to ringbuffer directly"),
copy_gma_to_hva() now returns copied data length instead of 0, so
need to change error return check for that.

Note: Looks this is caused by backmerge conflict resolving, so
4.11-rc4 is not impacted as commit 73dec95e6b ("drm/i915: Emit to
ringbuffer directly") is not in 4.11. But need to fix this before I
can apply 4.12 stuff against drm-intel-next correctly.

Otherwise this can also prevent modesets e.g. for switching VTs, when
multiple monitors with different native resolutions are connected.

The depths must match though, so keep the != test for that.

Also update the DRM_DEBUG output to be slightly more accurate, this
doesn't only affect requests from userspace.

590379aef2 drm/i915: make context status notifier head be per engine
GVTg has introduced the context status notifier to schedule the GVTg
workload. At that time, the notifier is bound to GVTg context only,
so GVTg is not aware of host workloads.

Now we are going to improve GVTg's guest workload scheduler policy,
and add Guc emulation support for new Gen graphics. Both these two
features require acknowledgment for all contexts running on hardware.
(But will not alter host workload.) So here try to make some change.

The change is simple:
  1. Move the context status notifier head from i915_gem_context to
     intel_engine_cs. Which means there is a notifier head per engine
     instead of per context. Execlist driver still call notifier for
     each context sched-in/out events of current engine.
  2. At GVTg side, it binds a notifier_block for each physical engine
     at GVTg initialization period. Then GVTg can hear all context
     status events.

In this patch, GVTg do nothing for host context event, but later
will add a function there. But in any case, the notifier callback is
a noop if this is no active vGPU.

Since intel_gvt_init() is called at early initialization stage and
require the status notifier head has been initiated, I initiate it in
intel_engine_setup().

v2: remove a redundant newline. (chris)

3d3d18f086 drm/i915: Avoid rcu_barrier() from reclaim paths (shrinker)
The rcu_barrier() takes the cpu_hotplug mutex which itself is not
reclaim-safe, and so rcu_barrier() is illegal from inside the shrinker.

62c58af32c drm/edid: detect SCDC support in HF-VSDB
This patch does following:
- Adds a new structure (drm_hdmi_info) in drm_display_info.
  This structure will be used to save and indicate if sink
  supports advanced HDMI 2.0 features
- Adds another structure drm_scdc within drm_hdmi_info, to
  reflect scdc support and capabilities in connected HDMI 2.0 sink.
- Checks the HF-VSDB block for presence of SCDC, and marks it
  in scdc structure
- If SCDC is present, checks if sink is capable of generating
  SCDC read request, and marks it in scdc structure.

V2: Addressed review comments
  Thierry:
  - Fix typos in commit message and make abbreviation consistent
    across the commit message.
  - Change structure object name from hdmi_info -> hdmi
  - Fix typos and abbreviations in description of structure drm_hdmi_info
    end the description with a full stop.
  - Create a structure drm_scdc, and keep all information related to SCDC
    register set (supported, read request supported) etc in it.

  Ville:
  - Change rr -> read_request
  - Call drm_detect_scrambling function drm_parse_hf_vsdb so that all
    of HF-VSDB parsing can be kept in same function, in incremental
    patches.

"The current implementation does not support "I2C Master Interface
Extended Read Mode" to read data addressed by non-zero segment
pointer, this means that if EDID has more than 1 extension blocks,
EDID reading operation won't succeed"

With this patch, dw-hdmi can read EDID data with 1/2/4 blocks.

22e098daae drm/exynos/dsi: make te-gpios optional
DSI forwards te-gpios interrupts to display controller, but if display
controller works in HW-TRIGGER mode this interrupt is not necessary.
Making te-gpios property optional allows to avoid generating spare
interrupts.
And also if panel device node of command mode panel device doesn't provide
te-gpios property then the panel driver failed to probe. This was a critial
issue.

With this patch we can not only get rid of 60 interrupt callbacks per second
but also fix the critial issues.

7b34734816 drm: vc4: remove redundant check of plane being non-null
The pointer plane is always null on the error path at label 'fail'
hence the check if it is non-null is redundant. We can therefore
remove the check and the destruction of plane as well as the fail
error path and instead just return an -ENOMEM ERR_PTR.

234516afbb drm/i915/glk: Enable pooled EUs for Geminilake
Geminilake also supports pooled EUs. Enable it.

It is unclear if the recommendation to disable it for 2x6 configurations
from commit e015dd69b2 ("drm/i915/bxt: Add WaEnablePooledEuFor2x6")
should also apply to GLK, but it is applied anyway to be on the safe
side. That restriction can be lifted later if determined not to impact
performance.

The extra restriction should not impact user space either. The only user
space that uses this feature is Beignet, and it only does so for 3x6
devices. See See Beignet's commit 6901899ec90a ("Runtime: set the sub
slice according to kernel pooled EU configure.").

v2: Improve commit message. (Mika, Roy)

fa7e8b55e9 drm/i915: Fix vGPU balloon for ggtt guard page
From commit a6508ded2a ("drm/i915: Use page coloring to provide the guard
page at the end of the GTT"), we no longer explicitly subtract guard page
at end for GGTT address space init, so shouldn't subtract that for vGPU
balloon too, as that will leave that end page to be available for
vGPU. Change balloon to cover full range too.

This fixes to use recent drm-intel tip kernel for guest OS. Found by GVT-g
cmd parser that guest kernel uses end page as scratch then try to run
MI_STORE_REG_MEM onto it.

bb7d785688 drm/vc4: Add HDMI audio support
The HDMI encoder IP embeds all needed blocks to output audio, with a
custom DAI called MAI moving audio between the two parts of the HDMI
core.  This driver now exposes a sound card to let users stream audio
to their display.

Using the hdmi-codec driver has been considered here, but MAI meant
having to significantly rework hdmi-codec, and it would have left
little shared code with the I2S mode anyway.

The encoder requires that the audio be SPDIF-formatted frames only,
which alsalib will format-convert for us.

This patch is the combined work of Eric Anholt (initial register setup
with a separate dmaengine driver and using simple-audio-card) and
Boris Brezillon (moving it all into HDMI, massive debug to get it
actually working), and which Eric has the permission to release.

v2: Drop "-audio" from sound card name, since that's already implied
    (suggestion by Boris)

3fc03069bc drm/i915: make context status notifier head be per engine
GVTg has introduced the context status notifier to schedule the GVTg
workload. At that time, the notifier is bound to GVTg context only,
so GVTg is not aware of host workloads.

Now we are going to improve GVTg's guest workload scheduler policy,
and add Guc emulation support for new Gen graphics. Both these two
features require acknowledgment for all contexts running on hardware.
(But will not alter host workload.) So here try to make some change.

The change is simple:
  1. Move the context status notifier head from i915_gem_context to
     intel_engine_cs. Which means there is a notifier head per engine
     instead of per context. Execlist driver still call notifier for
     each context sched-in/out events of current engine.
  2. At GVTg side, it binds a notifier_block for each physical engine
     at GVTg initialization period. Then GVTg can hear all context
     status events.

In this patch, GVTg do nothing for host context event, but later
will add a function there. But in any case, the notifier callback is
a noop if this is no active vGPU.

Since intel_gvt_init() is called at early initialization stage and
require the status notifier head has been initiated, I initiate it in
intel_engine_setup().

v2: remove a redundant newline. (chris)

31de73501a drm/i915/scheduler: emulate a scheduler for guc
This emulates execlists on top of the GuC in order to defer submission of
requests to the hardware. This deferral allows time for high priority
requests to gazump their way to the head of the queue, however it nerfs
the GuC by converting it back into a simple execlist (where the CPU has
to wake up after every request to feed new commands into the GuC).

v2: Drop hack status - though iirc there is still a lockdep inversion
between fence and engine->timeline->lock (which is impossible as the
nesting only occurs on different fences - hopefully just requires some
judicious lockdep annotation)
v3: Apply lockdep nesting to enabling signaling on the request, using
the pattern we already have in __i915_gem_request_submit();
v4: Replaying requests after a hang also now needs the timeline
spinlock, to disable the interrupts at least
v5: Hold wq lock for completeness, and emit a tracepoint for enabling signal
v6: Reorder interrupt checking for a happier gcc.
v7: Only signal the tasklet after a user-interrupt if using guc scheduling
v8: Restore lost update of rq through the i915_guc_irq_handler (Tvrtko)
v9: Avoid re-initialising the engine->irq_tasklet from inside a reset
v10: Hook up the execlists-style tracepoints
v11: Clear the execlists irq_posted bit after taking over the interrupt/tasklet

are easier, but in residency calculations raw units would have been
the easiest.

As there is not much advantage of using base-ten clock through

47c21d9a1a drm/i915: Extend vlv/chv residency resolution
Vlv and chv residency counters are 40 bits in width.
With a control bit, we can choose between upper or lower
32 bit window into this counter.

Lets toggle this bit on and off on and read both parts.
As a result we can push the wrap from 13 seconds to 54
minutes.

v2: commit msg, loop readability, goto elimination (Chris)
v3: bug ref, divide outside runtime pm lock (Chris)
