e33df4ca87 drm/doc: More fine-tuning on userspace review requirements
With Eric's patch

commit ba6e798ecf
Author: Eric Anholt <eric@anholt.net>
Date:   Wed Apr 24 11:56:17 2019 -0700

    drm/doc: Document expectation that userspace review looks at kernel uAPI.

there's been concerns raised that we expect userspace people to do
in-depth kernel patch review. That's not reasonable, same way kernel
people can't review all the userspace we have. Try to clarify
expectations a bit more.

BOs on the LRU might be blocked during command submission

Avoid this by blocking for the first busy BO not locked by

There's some unnecessary mem allocation for CS_TFM_ID. What's worse, it
depends on LUT size and since it's 4K for CS_TFM_1D, it is 16x bigger

8633d96d3c drm/amd/display: fix issues with bad AUX reply on some displays
[Why]
Some displays take some time to power up AUX CH once they are
put into D3 state via write to DPCD 600h=2.

Interestingly enough, some display may simply NACK, but some might
also ACK with a bunch of 0s, which can cause issues with receiver
cap retrieval. Note that not all DPCD address return 0s, but in
particular it has been observed on some higher DPCD address such
as DPCD 2200h, etc.

[How]
Based on spec, receiver will monitor differential signal while in D3 and
AUX CH is in low power mode. When detected, it may allow up to
1 ms to power up AUX CH and reply.

If we read Sink power state D3, we should add 1 ms delay to satisfy
this spec requirement.

44ab1aa84a drm/amd/display: do not power on eDP power rail early
[Why]
Modern Standby may toggle display adapter state between D0
and D3 state unpredictably.
But events that cause transition to D0 are not always resulting
in a display light up scenario.

Modern eDP panels should be able to power on panel logic
quickly upon VDD going high. Based on spec, the T3 time
between VDD on and HPD high can be between 0 and 80 ms.

Doing any tricky sorts of optimization by powering on panel
VDD early during D0 transition on can negatively impact other
features due to unnecessary power drain and toggling when
final system state does not intend for the panel to be lit up.

We need OEMs to source higher end panels that have T3 time
close to 0 if they want quick S3/Modern Standby resume times.

[How]
Remove panel VDD power on in init_hw

4b0ab7dd37 drm/amd/display: fix crash on setmode when mode is close to bw limit
[why]
during It's possible to call dcn_validate_bandwidth with no plane.
In that case, as we are only intersted in if output timing is supported or not,
even if we cannot support native resolution, we still want to support lower
resolution if it is valid

[how]
if there exist no surface, make viewport/rec_out size at max 1080p. It is
already known that 1080p x 6(max # of pipes) is supported, so if we fail
validation, it is because of the stream

789142eb8b drm/amdgpu:Fix the unpin warning about csb buffer
As it will destroy clear_state_obj, and also will unpin it in the
gfx_v9_0_sw_fini, so don't need to
call amdgpu_bo_free_kernel in gfx_v9_0_sw_fini, or it will have unpin warning.

The pixel clock unit in the first two registers (0x00 and 0x01) of
sii9022 is 10kHz, not 1kHz as in struct drm_display_mode. Division by
10 fixes the issue.

46648a3cec drm/bridge: tc358767: copy the mode data, instead of storing the pointer
In tc_bridge_mode_set callback, we store the pointer to the given
drm_display_mode, and use the mode later. Storing a pointer in such a
way looks very suspicious to me, and I have observed odd issues where
the timings were apparently (at least mostly) zero.

Do a copy of the drm_display_mode instead to ensure we don't refer to
freed/modified data.
