[Why]
Driver incorrectly checks if pointer variable OutBpp is null instead of
if the value being pointed to is zero.

[How]
Dereference OutBpp before checking for a value of zero.

[why &amp; how]
we have two SSC_En:
we get ssc_info from dce_info for MPLL_SSC_EN.
we used to call VBIOS cmdtbl's smu_info's SS persentage for DPRECLK SS info,
is used for DP AUDIO and VBIOS' smu_info table was from systemIntegrationInfoTable.

since dcn35 VBIOS removed smu_info, driver need to use integrationInfotable directly.

<title>drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x</title>

<content type='text'>
There have recently been changes that break backwards compatibility,
that were introduced into DMUB firmware (for DCN32x) concerning FPO and
SubVP. So, since those are just power optimization features, we can just
disable them unless the user is using a new enough version of DMUB
firmware.

<title>drm/amdkfd: svm range always mapped flag not working on APU</title>

<id>ebab8c3eb6a6515dc14cd93fc29dd287709da6d3</id>
<content type='text'>
On gfx943 APU there is no VRAM and page migration, queue CWSR area, svm
range with always mapped flag, is not mapped to GPU correctly. This
works fine if retry fault on CWSR area can be recovered, but could cause
deadlock if there is another retry fault recover waiting for CWSR to
finish.

Fix this by mapping svm range with always mapped flag to GPU with ACCESS
attribute if XNACK ON.

There is side effect, because all GPUs have ACCESS attribute by default
on new svm range with XNACK on, the CWSR area will be mapped to all GPUs
after this change. This side effect will be fixed with Thunk change to
set CWSR svm range with ACCESS_IN_PLACE attribute on the GPU that user
queue is created.

The pipe DMC seems to be making a mess of things in ADL. Various weird
symptoms have been observed such as missing vblank irqs, typicalle
happening when using multiple displays.

Keep all pipe DMC event handlers disabled until needed (which is never
atm). This is also what Windows does on ADL+.

We can also drop DG2 from disable_all_flip_queue_events() since
on DG2 the pipe DMC is the one that handles the flip queue events.
