drm/amd/powerplay: fix uninitialized variable

2017-11-02T08:49:14+00:00

commit 8b95f4f730cba02ef6febbdc4ca7e55ca045b00e upstream.

refresh_rate was not initialized when program
display gap.
this patch can fix vce ring test failed
when do S3 on Polaris10.

drm/nouveau/mmu: flush tlbs before deleting page tables

2017-10-27T08:38:07+00:00

commit 77913bbcb43ac9a07a6fe849c2fd3bf85fc8bdd8 upstream.

Even though we've zeroed the PDE, the GPU may have cached the PD, so we
need to flush when deleting them.

Noticed while working on replacement MMU code, but a backport might be a
good idea, so let's fix it in the current code too.

drm/nouveau/bsp/g92: disable by default

2017-10-27T08:38:07+00:00

commit 194d68dd051c2dd5ac2b522ae16100e774e8d869 upstream.

G92's seem to require some additional bit of initialization before the
BSP engine can work. It feels like clocks are not set up for the
underlying VLD engine, which means that all commands submitted to the
xtensa chip end up hanging. VP seems to work fine though.

This still allows people to force-enable the bsp engine if they want to
play around with it, but makes it harder for the card to hang by
default.

drm/amdgpu: refuse to reserve io mem for split VRAM buffers

2017-10-21T15:21:36+00:00

[ Upstream commit 4694335dad7357e9b3d7822ab13049014d74d8b0 ]

When the fast blit path fails while attempting to move a buffer from RAM
to VRAM, we fall back to a CPU-based memcpy that cannot handle split VRAM
buffers. Instead of crashing, simply fail the buffer move.

Ideally, we would teach TTM about split buffers so that the fallback still
works in this case, but that is quite involved. So for now, apply the
simplest possible fix.

drm/i915/bios: parse DDI ports also for CHV for HDMI DDC pin and DP AUX channel

2017-10-18T07:35:40+00:00

commit ea850f64c2722278f150dc11de2141baeb24211c upstream.

While technically CHV isn't DDI, we do look at the VBT based DDI port
info for HDMI DDC pin and DP AUX channel. (We call these "alternate",
but they're really just something that aren't platform defaults.)

In commit e4ab73a13291 ("drm/i915: Respect alternate_ddc_pin for all DDI
ports") Ville writes, "IIRC there may be CHV system that might actually
need this."

I'm not sure why there couldn't be even more platforms that need this,
but start conservative, and parse the info for CHV in addition to DDI.

drm/i915: Read timings from the correct transcoder in intel_crtc_mode_get()

2017-10-18T07:35:40+00:00

commit 7b50f7b24cd6c98541f1af53bddc5b6e861ee8c8 upstream.

intel_crtc->config->cpu_transcoder isn't yet filled out when
intel_crtc_mode_get() gets called during output probing, so we should
not use it there. Instead intel_crtc_mode_get() figures out the correct
transcoder on its own, and that's what we should use.

If the BIOS boots LVDS on pipe B, intel_crtc_mode_get() would actually
end up reading the timings from pipe A instead (since PIPE_A==0),
which clearly isn't what we want.

It looks to me like this may have been broken by
commit eccb140bca67 ("drm/i915: hw state readout&check support for cpu_transcoder")
as that one removed the early initialization of cpu_transcoder from
intel_crtc_init().

drm/i915/edp: Get the Panel Power Off timestamp after panel is off

2017-10-18T07:35:40+00:00

commit d7ba25bd9ef802ff02414e9105f4222d1795f27a upstream.

Kernel stores the time in jiffies at which the eDP panel is turned
off. This should be obtained after the panel is off (after the
wait_panel_off). When we next attempt to turn the panel on, we use the
difference between the timestamp at which we want to turn the panel on
and timestamp at which panel was turned off to ensure that this is equal
to panel power cycle delay and if not we wait for the remaining
time. Not waiting for the panel power cycle delay can cause the panel to
not turn on giving rise to AUX timeouts for the attempted AUX
transactions.

the combo out already at the VBT parsing phase.
