[ Upstream commit e0a200ab4b72afd581bd6f82fc1ef510a4fb5478 ]
DisplayID spec v1.3 revision history notes do claim that
the toplogy block was added in v1.3 so requiring structure
v1.2 would seem correct, but there is at least one EDID in
edid.tv with a topology block and structure v1.0. And
there are also EDIDs with DisplayID structure v1.3 which
seems to be totally incorrect as DisplayID spec v1.3 lists
structure v1.2 as the only legal value.
Unfortunately I couldn't find copies of DisplayID spec
v1.0-v1.2 anywhere (even on vesa.org), so I'll have to
go on empirical evidence alone.
We used to parse the topology block on all v1.x
structures until the check for structure v2.0 was added.
Let's go back to doing that as the evidence does suggest
that there are DisplayIDs in the wild that would miss
out on the topology stuff otherwise.
Also toss out DISPLAY_ID_STRUCTURE_VER_12 entirely as
it doesn't appear we can really use it for anything.
I *think* we could technically skip all the structure
version checks as the block tags shouldn't conflict
between v2.0 and v1.x. But no harm in having a bit of
extra sanity checks I guess.
So far I'm not aware of any user reported regressions
from overly strict check, but I do know that it broke
igt/kms_tiled_display's fake DisplayID as that one
gets generated with structure v1.0.

[ Upstream commit e80c219f52861e756181d7f88b0d341116daac2b ]
For the cbcr format, gt2 and gt4 are computed again after src_h has been
divided by vsub.
As src_h as already been divided by 2 before, introduce cbcr_src_h and
cbcr_src_w to keep a copy of those values to be used for cbcr gt2 and
gt4 computation.
This fixes yuv planes being unaligned vertically when down scaling to
1080 pixels from 2160.

[ Upstream commit 11ac72d033b9f577e8ba0c7a41d1c312bb232593 ]
The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ,
add the missing bus_format. Add missing connector type and bus_flags
as well.
Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is
capable of both RGB 18bit/24bit panel, the current configuration uses
18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6.
Support for the 24bit mode would require another entry in panel-simple
with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which
is out of scope of this fix.

[ Upstream commit 5d1a7493343cc00d9019880b686e4e0a0f649531 ]
As documented in the description of the transfer() function of
"struct drm_dp_aux", the transfer() function can be called at any time
regardless of the state of the DP port. Specifically if the kernel has
the DP AUX character device enabled and userspace accesses
"/dev/drm_dp_auxN" directly then the AUX transfer function will be
called regardless of whether a DP device is connected.
For eDP panels we have a special rule where we wait (with a 5 second
timeout) for HPD to go high. This rule was important before all panels
drivers were converted to call wait_hpd_asserted() and actually can be
removed in a future commit.
For external DP devices we never checked for HPD. That means that
trying to access the DP AUX character device (AKA `hexdump -C
/dev/drm_dp_auxN`) would very, very slowly timeout. Specifically on my
system:
$ time hexdump -C /dev/drm_dp_aux0
hexdump: /dev/drm_dp_aux0: Connection timed out
real 0m8.200s
We want access to the drm_dp_auxN character device to fail faster than
8 seconds when no DP cable is plugged in.
Let's add a test to make transfers fail right away if a device isn't
plugged in. Rather than testing the HPD line directly, we have the
dp_display module tell us when AUX transfers should be enabled so we
can handle cases where HPD is signaled out of band like with Type C.

[ Upstream commit 01a2c5123e27b3c4685bf2fc4c2e879f6e0c7b33 ]
In the case where `conn_routes` is true we allocate an extra slot in
the `ddp_comp` array but mtk_drm_crtc_create() never seemed to
initialize it in the test case I ran. For me, this caused a later
crash when we looped through the array in mtk_drm_crtc_mode_valid().
This showed up for me when I booted with `slub_debug=FZPUA` which
poisons the memory initially. Without `slub_debug` I couldn't
reproduce, presumably because the later code handles the value being
NULL and in most cases (not guaranteed in all cases) the memory the
allocator returned started out as 0.
It really doesn't hurt to initialize the array with devm_kcalloc()
since the array is small and the overhead of initting a handful of
elements to 0 is small. In general initting memory to zero is a safer
practice and usually it's suggested to only use the non-initting alloc
functions if you really need to.
Let's switch the function to use an allocation function that zeros the
memory. For me, this avoids the crash.

[ Upstream commit 80cc8c0d09e6bab3bd016ddaccd0570cadbe1891 ]
Similar to other variants, the LTK050H3148W wants to run in video mode
when displaying data. So far only the Synopsis DSI driver was using this
panel and it is always switching to video mode, independent of this flag
being set.
Other DSI drivers might handle this differently, so add the flag.

The issue could occur when the index 'i' exceeds the number of transfer
function points (TRANSFER_FUNC_POINTS).
The fix adds a check to ensure 'i' is within bounds before accessing the

[ Upstream commit 8df1ddb5bf11ab820ad991e164dab82c0960add9 ]
If an eDP panel is not powered on then any attempts to talk to it over
the DP AUX channel will timeout. Unfortunately these attempts may be
quite slow. Userspace can initiate these attempts either via a
/dev/drm_dp_auxN device or via the created i2c device.
Making the DP AUX drivers timeout faster is a difficult proposition.
In theory we could just poll the panel's HPD line in the AUX transfer
function and immediately return an error there. However, this is
easier said than done. For one thing, there's no hard requirement to
hook the HPD line up for eDP panels and it's OK to just delay a fixed
amount. For another thing, the HPD line may not be fast to probe. On
parade-ps8640 we need to wait for the bridge chip's firmware to boot
before we can get the HPD line and this is a slow process.
The fact that the transfers are taking so long to timeout is causing
real problems. The open source fwupd daemon sometimes scans DP busses
looking for devices whose firmware need updating. If it happens to
scan while a panel is turned off this scan can take a long time. The
fwupd daemon could try to be smarter and only scan when eDP panels are
turned on, but we can also improve the behavior in the kernel.
Let's let eDP panels drivers specify that a panel is turned off and
then modify the common AUX transfer code not to attempt a transfer in
this case.

[ Upstream commit 172695f145fb4798ab605e8a73f6e87711930124 ]
In case the LCDIF is enabled in DT but unused, the clocks used by the
LCDIF are not enabled. Those clocks may even have a use count of 0 in
case there are no other users of those clocks. This can happen e.g. in
case the LCDIF drives HDMI bridge which has no panel plugged into the
HDMI connector.
Do not attempt to disable clocks in the suspend callback and re-enable
clocks in the resume callback unless the LCDIF is enabled and was in
use before the system entered suspend, otherwise the driver might end
up trying to disable clocks which are already disabled with use count
0, and would trigger a warning from clock core about this condition.
Note that the lcdif_rpm_suspend() and lcdif_rpm_resume() functions
internally perform the clocks disable and enable operations and act
as runtime PM hooks too.

While the cause of these is not yet clear, these messages made me notice
that the aux transactions causing these transactions were succeeding - not
failing. As it turns out, this is because we're currently not returning the
correct variable when r535_dp_aux_xfer() hits an error - causing us to
never propagate GSP errors for failed aux transactions to userspace.

[ Upstream commit e18aeeda0b6905c333df5a0566b99f5c84426098 ]
For a given bridge pipeline if any bridge sets pre_enable_prev_first
flag then the pre_enable for the previous bridge will be called before
pre_enable of this bridge and opposite is done for post_disable.
These are the potential bridge flags to alter bridge init order in order
to satisfy the MIPI DSI host and downstream panel or bridge to function.
However the existing pre_enable_prev_first logic with associated bridge
ordering has broken for both pre_enable and post_disable calls.
[pre_enable]
The altered bridge ordering has failed if two consecutive bridges on a
given pipeline enables the pre_enable_prev_first flag.
Example:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
In this example, Bridge 4 and Bridge 5 have pre_enable_prev_first.
The logic looks for a bridge which enabled pre_enable_prev_first flag
on each iteration and assigned the previou bridge to limit pointer
if the bridge doesn't enable pre_enable_prev_first flags.
If control found Bridge 2 is pre_enable_prev_first then the iteration
looks for Bridge 3 and found it is not pre_enable_prev_first and assigns
it's previous Bridge 4 to limit pointer and calls pre_enable of Bridge 3
and Bridge 2 and assign iter pointer with limit which is Bridge 4.
Here is the actual problem, for the next iteration control look for
Bridge 5 instead of Bridge 4 has iter pointer in previous iteration
moved to Bridge 4 so this iteration skips the Bridge 4. The iteration
found Bridge 6 doesn't pre_enable_prev_first flags so the limit assigned
to Encoder. From next iteration Encoder skips as it is the last bridge
for reverse order pipeline.
So, the resulting pre_enable bridge order would be,
- Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5.
This patch fixes this by assigning limit to next pointer instead of
previous bridge since the iteration always looks for bridge that does
NOT request prev so assigning next makes sure the last bridge on a
given iteration what exactly the limit bridge is.
So, the resulting pre_enable bridge order with fix would be,
- Panel, Bridge 1, Bridge 3, Bridge 2, Bridge 6, Bridge 5, Bridge 4,
Encoder.
[post_disable]
The altered bridge ordering has failed if two consecutive bridges on a
given pipeline enables the pre_enable_prev_first flag.
Example:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
In this example Bridge 5 and Bridge 4 have pre_enable_prev_first.
The logic looks for a bridge which enabled pre_enable_prev_first flags
on each iteration and assigned the previou bridge to next and next to
limit pointer if the bridge does enable pre_enable_prev_first flag.
If control starts from Bridge 6 then it found next Bridge 5 is
pre_enable_prev_first and immediately the next assigned to previous
Bridge 6 and limit assignments to next Bridge 6 and call post_enable
of Bridge 6 even though the next consecutive Bridge 5 is enabled with
pre_enable_prev_first. This clearly misses the logic to find the state
of next conducive bridge as everytime the next and limit assigns
previous bridge if given bridge enabled pre_enable_prev_first.
So, the resulting post_disable bridge order would be,
- Encoder, Bridge 6, Bridge 5, Bridge 4, Bridge 3, Bridge 2, Bridge 1,
Panel.
This patch fixes this by assigning next with previou bridge only if the
bridge doesn't enable pre_enable_prev_first flag and the next further
assign it to limit. This way we can find the bridge that NOT requested
prev to disable last.
So, the resulting pre_enable bridge order with fix would be,
- Encoder, Bridge 4, Bridge 5, Bridge 6, Bridge 2, Bridge 3, Bridge 1,
Panel.
Validated the bridge init ordering by incorporating dummy bridges in
the sun6i-mipi-dsi pipeline

[ Upstream commit f5b9053398e70a0c10aa9cb4dd5910ab6bc457c5 ]
There is a race condition when re-creating a kfd_process for a process.
This has been observed when a process under the debugger executes
exec(3). In this scenario:
- The process executes exec.
- This will eventually release the process's mm, which will cause the
kfd_process object associated with the process to be freed
(kfd_process_free_notifier decrements the reference count to the
kfd_process to 0). This causes kfd_process_ref_release to enqueue
kfd_process_wq_release to the kfd_process_wq.
- The debugger receives the PTRACE_EVENT_EXEC notification, and tries to
re-enable AMDGPU traps (KFD_IOC_DBG_TRAP_ENABLE).
- When handling this request, KFD tries to re-create a kfd_process.
This eventually calls kfd_create_process and kobject_init_and_add.
At this point the call to kobject_init_and_add can fail because the
old kfd_process.kobj has not been freed yet by kfd_process_wq_release.
This patch proposes to avoid this race by making sure to drain
kfd_process_wq before creating a new kfd_process object. This way, we
know that any cleanup task is done executing when we reach
kobject_init_and_add.

During DP tunnel creation, CM preallocates BW and reduces
estimated BW of other DPIA. CM release preallocation only
when allocation is complete. Display mode validation logic
validates timings based on bw available per host router.
In multi display setup, this causes bw allocation failure
when allocation greater than estimated bw.

Do zero alloc to make the CM to release preallocation and
update estimated BW correctly for all DPIAs per host router.

[ Upstream commit d7a5c9de99b3a9a43dce49f2084eb69b5f6a9752 ]
commit 4bce244272513 ("drm/etnaviv: disable tx clock gating for GC7000
rev6203") accidentally applied the fix for i.MX8MN errata ERR050226 to
GC2000 instead of GC7000, failing to disable tx clock gating for GC7000
rev 0x6023 as intended.
Additional clean-up further propagated this issue, partially breaking
the clock gating fixes added for GC7000 rev 6202 in commit 432f51e7deeda
("drm/etnaviv: add clock gating workaround for GC7000 r6202").

[ Upstream commit fe93b0927bc58cb1d64230f45744e527d9d8482c ]
Here are the corrections needed for the queue ring buffer size
calculation for the following cases:
- Remove the KIQ VM flush ring usage.
- Add the invalidate TLBs packet for gfx10 and gfx11 queue.
- There's no VM flush and PFP sync, so remove the gfx9 real
ring and compute ring buffer usage.

[ Upstream commit 1e214f7faaf5d842754cd5cfcd76308bfedab3b5 ]
Do VRAM accounting when doing migrations to vram to make sure
there is enough available VRAM and migrating to VRAM doesn't evict
other possible non-unified memory BOs. If migrating to VRAM fails,
driver can fall back to using system memory seamlessly.

[ Upstream commit 30d1cda8ce31ab49051ff7159280c542a738b23d ]
During mode-2 reset, pci config space registers are affected at device
side. However, certain platforms have switches which assign virtual BAR
addresses and returns the same even after device is reset. This
affects pci_restore_state() as it doesn't issue another config write, if
the value read is same as the saved value.
Add a workaround to write saved config space values from driver side.
Presently, these switches are in platforms with SMU v13.0.6 SOCs, hence
restrict the workaround only to those.

[ Upstream commit b0b13d532105e0e682d95214933bb8483a063184 ]
Make SVM BOs more likely to get evicted than other BOs. These BOs
opportunistically use available VRAM, but can fall back relatively
seamlessly to system memory. It also avoids SVM migrations evicting
other, more important BOs as they will evict other SVM allocations
first.
