[ Upstream commit 81ad7f9f78e4ff80e95be8282423f511b84f1166 ]

The OneGX1 Pro has a fairly unique combination of generic strings,
but we additionally match on the BIOS date just to be safe.

Use AST_MAX_HWC_HEIGHT for setting offset_y in the cursor plane's
atomic_check. The code used AST_MAX_HWC_WIDTH instead. This worked
because both constants has the same value.

[ Upstream commit dc739820ff90acccd013f6bb420222978a982791 ]

a connector is leaked upon module unload, it seems that we should do
similar to sample driver as suggested in drm_drv.c.

Adding drm_atomic_helper_shutdown() in ast_pci_remove to prevent leaking.

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

[ Upstream commit 349a19b2f1b01e713268c7de9944ad669ccdf369 ]

[why]
This check for ASIC revision is no longer useful and causes
lightup issues after a topology change in MST DSC scenario.
In this case, DSC configs should be recalculated for the new
topology. This check prevented that from happening on certain
ASICs that do, in fact, support DSC.

[how]
Change the ASIC revision to instead check if DSC is supported.

[ Upstream commit 6ad98e8aeb0106f453bb154933e8355849244990 ]

[Why]
There is a window of time where we optimize bandwidth due to no streams
enabled will enable PSTATE changing but HUBPs are not disabled yet.
This results in underflow counter increasing in some hotplug scenarios.

[How]
Set the optimize-bandwidth flag for later processing once all the HUBPs
are properly disabled.

From: Xiaogang Chen <xiaogang.chen@amd.com>

[ Upstream commit b6f91fc183f758461b9462cc93e673adbbf95c2d ]

amdgpu DM handles INTERRUPT_LOW_IRQ_CONTEXT interrupt(hpd, hpd_rx) by using work
queue and uses single work_struct. If new interrupt is recevied before the
previous handler finished, new interrupts(same type) will be discarded and
driver just sends "amdgpu_dm_irq_schedule_work FAILED" message out. If some
important hpd, hpd_rx related interrupts are missed by driver the hot (un)plug
devices may cause system hang or instability, such as issues with system
resume from S3 sleep with mst device connected.

This patch dynamically allocates new amdgpu_dm_irq_handler_data for new
interrupts if previous INTERRUPT_LOW_IRQ_CONTEXT interrupt work has not been
handled. So the new interrupt works can be queued to the same workqueue_struct,
instead of discard the new interrupts. All allocated amdgpu_dm_irq_handler_data
are put into a single linked list and will be reused after.

When unloading driver after killing some applications, it will hit sdma
flush tlb job timeout which is called by ttm_bo_delay_delete. So
to avoid the job submit after fence driver fini, call ttm_bo_lock_delayed_workqueue
before fence driver fini. And also put drm_sched_fini before waiting fence.

[ Upstream commit cdfd4c689e2a52c313b35ddfc1852ff274f91acb ]

WLED3_SINK_REG_SYNC is, as the name implies, a sink register offset.
Therefore, use the sink address as base instead of the ctrl address.

This fixes the sync toggle on wled4, which can be observed by the fact
that adjusting brightness now works.

It has no effect on wled3 because sink and ctrl base addresses are the
same.  This allows adjusting the brightness without having to disable
then reenable the module.

From: Kiran Gunda <kgunda@codeaurora.org>

[ Upstream commit 4d6e9cdff7fbb6bef3e5559596fab3eeffaf95ca ]

Currently, for WLED5, the FSC (Full scale current) setting is not
updated properly due to driver toggling the wrong register after
an FSC update.

On WLED5 we should only toggle the MOD_SYNC bit after a brightness
update. For an FSC update we need to toggle the SYNC bits instead.

Fix it by adopting the common wled3_sync_toggle() for WLED5 and
introducing new code to the brightness update path to compensate.

[ Upstream commit 9962849d0871f5e53d0e3b3d84561f8f2847fbf4 ]

Since encoder mappings for connectors are exposed to userspace, we should
be attaching the encoder before exposing the connector to userspace. Just a
drive-by fix for an issue I noticed while fixing up usages of
drm_dp_aux_init()/drm_dp_aux_register() across the tree.

From: Lyude Paul <lyude@redhat.com>

[ Upstream commit 212ee8db84600f7b279b8645c62a112bff310995 ]

Just another issue I noticed while correcting usages of
drm_dp_aux_init()/drm_dp_aux_register() around the tree. If any of the
steps in anx78xx_bridge_attach() fail, we end up leaking resources. So,
let's fix that (and fix leaking a DP AUX adapter in the process) by
unrolling on errors.

From: Jonathan Kim <jonathan.kim@amd.com>

[ Upstream commit 4ac5617c4b7d0f0a8f879997f8ceaa14636d7554 ]

The psp supplies the link type in the upper 2 bits of the psp xgmi node
information num_hops field.  With a new link type, Aldebaran has these
bits set to a non-zero value (1 = xGMI3) so the KFD topology will report
the incorrect IO link weights without proper masking.
The actual number of hops is located in the 3 least significant bits of
this field so mask if off accordingly before passing it to the KFD.

[ Upstream commit 50e2fc36e72d4ad672032ebf646cecb48656efe0 ]

If get_num_sdma_queues or get_num_xgmi_sdma_queues is 0, we end up
doing a shift operation where the number of bits shifted equals
number of bits in the operand. This behaviour is undefined.

Set num_sdma_queues or num_xgmi_sdma_queues to ULLONG_MAX, if the
count is >= number of bits in the operand.

[ Upstream commit 6a30a92997eee49554f72b462dce90abe54a496f ]

[Why]
dc_cursor_position do not initialise position.translate_by_source when
crtc or plane->state->fb is NULL. UBSAN caught this error in
dce110_set_cursor_position, as the value was garbage.

[How]
Initialise dc_cursor_position structure elements to 0 in handle_cursor_update
before calling get_cursor_position.

From: Aric Cyr <aric.cyr@amd.com>

[ Upstream commit 4710430a779e6077d81218ac768787545bff8c49 ]

[Why]
When unplugging a display, the underflow counter can be seen to
increase because PSTATE switch is allowed even when some planes are not
blanked.

[How]
Check that all planes are not active instead of all streams before
allowing PSTATE change.

[ Upstream commit b4142fc4d52d051d4d8df1fb6c569e5b445d369e ]

vkms_vblank_simulate() uses WARN_ON for timing-dependent condition
(timer overrun). This is a mis-use of WARN_ON, WARN_ON must be used
to denote kernel bugs. Use pr_warn() instead.
