The minimum firmware versions required for user queue functionality
have been increased to address an issue where the queue privilege
state was lost during queue connect operations.
The problem occurred because the privilege state was being restored
to its initial value at the beginning of the function, overwriting
the state that was properly set during the queue connect case.
This commit updates the minimum version requirements:
- ME firmware from 2390 to 2420
- PFP firmware from 2530 to 2580
- MEC firmware from 2600 to 2650
- MES firmware remains at 120
These updated firmware versions contain the necessary fixes to
properly maintain queue privilege state throughout connect operations.

Current dma-buf vmap semantics require that the mapped buffer remains
in place until the corresponding vunmap has completed.
For GEM-SHMEM, this used to be guaranteed by a pin operation while creating
an S/G table in import. GEM-SHMEN can now import dma-buf objects without
creating the S/G table, so the pin is missing. Leads to page-fault errors,
such as the one shown below.

In this stack strace, udl (based on GEM-SHMEM) imported and vmap'ed a
dma-buf from amdgpu. Amdgpu relocated the buffer, thereby invalidating the
mapping.
Provide a custom dma-buf vmap method in amdgpu that pins the object before
mapping it's buffer's pages into kernel address space. Do the opposite in
vunmap.
Note that dma-buf vmap differs from GEM vmap in how it handles relocation.
While dma-buf vmap keeps the buffer in place, GEM vmap requires the caller
to keep the buffer in place. Hence, this fix is in amdgpu's dma-buf code
instead of its GEM code.
A discussion of various approaches to solving the problem is available
at [1].

- try (GTT | VRAM); drop CPU domain (Christian)

On DCE 6, DP audio was not working. However, it worked when an
HDMI monitor was also plugged in.
Looking at dce_aud_wall_dto_setup it seems that the main
difference is that we use DTO1 when only DP is plugged in.
When programming DTO1, it uses audio_dto_source_clock_in_khz
which is set from get_dp_ref_freq_khz
The dce60_get_dp_ref_freq_khz implementation looks incorrect,
because DENTIST_DISPCLK_CNTL seems to be always zero on DCE 6,
so it isn't usable.
I compared dce60_get_dp_ref_freq_khz to the legacy display code,
specifically dce_v6_0_audio_set_dto, and it turns out that in
case of DCE 6, it needs to use the display clock. With that,
DP audio started working on Pitcairn, Oland and Cape Verde.
However, it still didn't work on Tahiti. Despite having the
same DCE version, Tahiti seems to have a different audio device.
After some trial and error I realized that it works with the
default display clock as reported by the VBIOS, not the current
display clock.
The patch was tested on all four SI GPUs:
* Pitcairn (DCE 6.0)
* Oland (DCE 6.4)
* Cape Verde (DCE 6.0)
* Tahiti (DCE 6.0 but different)
The testing was done on Samsung Odyssey G7 LS28BG700EPXEN on
each of the above GPUs, at the following settings:
* 4K 60 Hz
* 1080p 60 Hz
* 1080p 144 Hz

For later VBIOS versions, the fractional feedback divider is
calculated as the remainder of dividing the feedback divider by
a factor, which is set to 1000000. For reference, see:
- calculate_fb_and_fractional_fb_divider
- calc_pll_max_vco_construct
However, in case of old VBIOS versions that have
set_pixel_clock_v3, they only have 1 byte available for the
fractional feedback divider, and it's expected to be set to the
remainder from dividing the feedback divider by 10.
For reference see the legacy display code:
- amdgpu_pll_compute
- amdgpu_atombios_crtc_program_pll
This commit fixes set_pixel_clock_v3 by dividing the fractional
feedback divider passed to the function by 100000.

Adjust the nominal (and performance) clocks for DCE 8-10,
and set them to 625 MHz, which is the value used by the legacy
display code in amdgpu_atombios_get_clock_info.
This was tested with Hawaii, Tonga and Fiji.
These GPUs can output 4K 60Hz (10-bit depth) at 625 MHz.
The extra 15% clock was added as a workaround for a Polaris issue
which uses DCE 11, and should not have been used on DCE 8-10 which
are already hardcoded to the highest possible display clock.
Unfortunately, the extra 15% was mistakenly copied and kept
even on code paths which don't affect Polaris.
This commit fixes that and also adds a check to make sure
not to exceed the maximum DCE 8-10 display clock.

This reverts commit 515986100d.
The dma_buf field in struct drm_gem_object is not stable over the
object instance's lifetime. The field becomes NULL when user space
releases the final GEM handle on the buffer object. This resulted
in a NULL-pointer deref.
Workarounds in commit 5307dce878 ("drm/gem: Acquire references on
GEM handles for framebuffers") and commit f6bfc9afc7 ("drm/framebuffer:
Acquire internal references on GEM handles") only solved the problem
partially. They especially don't work for buffer objects without a DRM
framebuffer associated.
Hence, this revert to going back to using .import_attach->dmabuf.

[Why]
A null pointer dereference vulnerability exists in the AMD display driver's
(DC module) cleanup function dc_destruct().
When display control context (dc->ctx) construction fails
(due to memory allocation failure), this pointer remains NULL.
During subsequent error handling when dc_destruct() is called,
there's no NULL check before dereferencing the perf_trace member
(dc->ctx->perf_trace), causing a kernel null pointer dereference crash.
[How]
Check if dc->ctx is non-NULL before dereferencing.
