[PATCH 01/20] drm/amd/display: Restructure DCN10 hubbub

[sunpeng.li-5C7GfCeVMHo]

From: Eryk Brol <eryk.brol@amd.com>

[Why]
Change DCN10 hubbub to use hubbub as a base and allow all future DCN
hubbubs to do the same instead of using DCN10_hubbub. This increases
readability and doesn't require future hubbubs to inherit anything
other than the base hubbub struct.

[How]
Create separate DCN10_hubbub struct which uses the hubbub struct as
a base.

[PATCH 02/20] drm/amd/display: Introduce DC VM interface

[sunpeng.li-5C7GfCeVMHo]

From: Eryk Brol <eryk.brol@amd.com>

Virtual memory allows display to support flipping to surfaces which
are not allocated contiguously in memory with physical addresses,
instead a 1-4 level page table is used.

This is beneficial because it allows the scattering of large surfaces
to improve memory efficiency and security.

[PATCH 03/20] drm/amd/display: Simplify underscan and ABM commit

[sunpeng.li-5C7GfCeVMHo]

From: David Francis <David.Francis@amd.com>

[Why]
Underscan and ABM are connector properties but require updates
to DC stream state.  Previously, on updates to these properties
the affected stream and all its planes were committed.
This is unnecessary; only a few fields on the stream need
to be changed.

[How]
If scaling or ABM have changed, change the stream and
create a stream update with those changes.  Call
DC with only those fields.

[PATCH 04/20] drm/amd/display: Know what a pageflip is

[sunpeng.li-5C7GfCeVMHo]

From: David Francis <David.Francis@amd.com>

[Why]
We were assuming that any commit with allow_modeset == false
was a pageflip.  This was against drm intention and only
worked by sheer luck

[How]
A pageflip is the change from one framebuffer to another

[PATCH 05/20] drm/amd/display: Call into DC once per multiplane flip

[sunpeng.li-5C7GfCeVMHo]

From: David Francis <David.Francis@amd.com>

[Why]
amdgpu_dm_commit_planes was performing multi-plane
flips incorrectly:

It waited for vblank once per flipped plane

It prepared flip ISR and acquired the corresponding vblank ref
once per plane, although it closed ISR and put the ref once
per crtc

It called into dc once per flipped plane, duplicating some work

[How]
Wait for vblank, get vblank ref, prepare flip ISR, and call into
DC only once, and only if there is a pageflip

Make freesync continue to update planes even if vrr information
has already been changed

[PATCH 06/20] drm/amd/display: Let updates with no scaling changes be fast

[sunpeng.li-5C7GfCeVMHo]

From: David Francis <David.Francis@amd.com>

[Why]
DC was assuming that any surface_update->scaling_info
meant the update was at least medium.  However, if nothing
has changed there is no scaling to program, so there is
no problem with the update being fast

[How]
If every update flag is not set, the update is fast

[PATCH 07/20] drm/amd/display: Perform plane updates only when needed

[sunpeng.li-5C7GfCeVMHo]

From: David Francis <David.Francis@amd.com>

[Why]
Our old logic: if pageflip, update freesync and plane address.
Otherwise, update everything.
This over-updated on non-pageflip cases, and it failed to
update if pageflip and non-pageflip changes occurred on
the same commit

[How]
Update flip_addrs on pageflips.
Update scaling_info when it changes.
Update color fields on color changes.
Updates plane_info always because we don't have a good way of
knowing when it needs to be updated.

Unfortunately, this means that every stream commit involves two
calls into DC.  In particular, on pageflips there is a second,
pointless update that changes nothing but costs several
microseconds (about a 50% increase in time taken). The update is
fast, but there are comparisons and some useless programming.

Leave TODOs indicating dissatisfaction.

[PATCH 08/20] drm/amd/display: Update DMCU versioning mechanism

[sunpeng.li-5C7GfCeVMHo]

From: Josip Pavic <Josip.Pavic@amd.com>

[Why]
Current date based versioning doesn't tell us about feature version
and build version, and is not useful for debug.

[How]
Add versioning based on feature and build

[PATCH 09/20] drm/amd/display: Create switching mechanism for ABM 2.2

[sunpeng.li-5C7GfCeVMHo]

From: Josip Pavic <Josip.Pavic@amd.com>

[Why]
Need method of detecting which version of the DMCU FW is loaded and
load the appropriate iRAM.

[How]
Create definition for ABM 2.2 iRAM, and load it if the DMCU FW version
number matches the ABM 2.2 version; otherwise load ABM 2.1 iRAM.

[PATCH 10/20] drm/amd/display: Fix use of uninitialized union

[sunpeng.li-5C7GfCeVMHo]

From: John Barberiz <John.Barberiz@amd.com>

[Why]
An uninitialized variable would randomly initialize to a large
value. This caused enough delay to fail DP Compliance Test 400.2.1.

[How]
Initialize the variable.

[PATCH 11/20] drm/amd/display: Default to linear output gamma

[sunpeng.li-5C7GfCeVMHo]

From: Krunoslav Kovac <Krunoslav.Kovac@amd.com>

[Why] Our output TF calculation doesn't work if no user-specified gamma
correction. Normally, user provides this, but driver sohuld just assume
default (linear) gamma otherwise.

[How] Remove output TF dependency on user gamma being provided.

[PATCH 13/20] revert "drm/amd/display: Add condition to sync eDP SW status and HW status"

[sunpeng.li-5C7GfCeVMHo]

From: Eric Yang <Eric.Yang2@amd.com>

[Why]
This change causes regression for S4 resume where gamma is not
programmed. The change incorrectly updates the requested dpms_off
state.

This reverts commit d2b1d6bbc56afab8ebae9d52d7ca0ea3569bd600.

[PATCH 14/20] drm/amd/display: take dpms_off into account for edp turn off logic

[sunpeng.li-5C7GfCeVMHo]

From: Eric Yang <Eric.Yang2@amd.com>

[why]
Previously we incorrectly skipped backlight control when stream is
present but dpms_off = true. This causes backlight to remain on in
the we boot up or resume into a external display only configuration
where VBIOS posted on the eDP.

[How]
Add dpms_off into the condition for edp need to turn off.

[PATCH 17/20] drm/amd/display: Poll pending down rep before clear payload allocation table

[sunpeng.li-5C7GfCeVMHo]

From: Martin Tsai <martin.tsai@amd.com>

[Why]
On current design, driver cannot handle the interrupt for
down reply when link training is processing. The DOWN REQ
send before link training will keep in the pending DOWN REP
state in the queue.
It makes the next DOWN REQ be queued until time out.

[How]
To add a polling sequence before clear payload allocation table
to make sure the pending DOWN REP can be handled.

[PATCH 18/20] drm/amd/display: Enable vblank interrupt during CRC capture

[sunpeng.li-5C7GfCeVMHo]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[Why]
In order to read CRC events when CRC capture is enabled the vblank
interrput handler needs to be running for the CRTC. The handler is
enabled while there is an active vblank reference.

When running IGT tests there will often be no active vblank reference
but the test expects to read a CRC value. This is valid usage (and
works on i915 since they have a CRC interrupt handler) so the reference
to the vblank should be grabbed while capture is active.

This issue was found running:

igt@kms_plane_multiple@atomic-pipe-b-tiling-none

The pipe-b is the only one in the initial commit and was not previously
active so no vblank reference is grabbed. The vblank interrupt is
not enabled and the test times out.

[How]
Keep a reference to the vblank as long as CRC capture is enabled.
If userspace never explicitly disables it then the reference is
also dropped when removing the CRTC from the context (stream = NULL).

[PATCH 19/20] drm/amd/display: Re-enable CRC capture following modeset

[sunpeng.li-5C7GfCeVMHo]

From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>

[Why]
During any modeset the CRTC stream is removed and a new stream is added.
This new stream doesn't carry over CRC capture state if it was
previously set.

[How]
Re-program the stream for CRC capture. The existing DRM callback can
be re-used here for the most part - the only modification needed is
additional locking now that it's called from within commit tail.

The second check after the || cannot be true if old_plane_state->fb ==
new_plane_state->fb, so it's dead code.

What about other references to state->allow_modeset in DM code ? You 
have one in  dm_determine_update_type_for_commit which will actually 
cause you to assume fast update because of state->allow_modeset == false.
Also - what about other types of plane updates which are more drastic 
(require full update) but will also have different FB, can't you wrongly 
assume they require page flip while it's actually needs 
commit_planes_to_stream ?

Other references (in atomic check) will still need to be addressed after 
this patch. This patch only fixes page-flips not working when 
state->allow_modeset = true. Everything else is mostly just about 
enabling us to do fast updates more frequently for better performance.

You're right about the fast vs full update bit (since we won't be 
waiting for vblank) but this gets addressed with another patch in this 
series, "drm/amd/display: Call into DC once per multiplane flip".

I don't remember the ordering of which these patches were originally 
applied but they may have changed when sent out to the mailing list.

For bisection purposes I think the ordering of:

[PATCH 06/20] drm/amd/display: Let updates with no scaling changes be fast
[PATCH 03/20] drm/amd/display: Simplify underscan and ABM commit
[PATCH 05/20] drm/amd/display: Call into DC once per multiplane flip
[PATCH 07/20] drm/amd/display: Perform plane updates only when needed
[PATCH 04/20] drm/amd/display: Know what a pageflip is

...probably makes the most logical sense.

This commit introduced a memory leak, see the attached report from kmemleak.

I can't see where this memory is freed, maybe this is the leak?
