CU-masking allows a KFD client to control the set of CUs used by a
user mode queue for executing compute dispatches. This can be used
for optimizing the partitioning of the GPU and minimize conflicts
between concurrent tasks.

On Raven multiple PPRs can be queued up by the hardware. When the
first of those requests is handled by the IOMMU driver, the memory
access succeeds. After that the application may be done with the
memory and unmap it. At that point the page table entries are
invalidated, but there are still outstanding duplicate PPRs for those
addresses. When the IOMMU driver processes those duplicate requests,
it finds invalid page table entries and triggers an invalid PPR fault.
As a workaround, don't signal invalid PPR faults on Raven to avoid
segfaulting applications that haven't done anything wrong. As a side
effect, real GPU memory access faults may go unnoticed by the
application.

On Raven Invalid PPRs (peripheral page requests) can be reported
because multiple PPRs can be still queued when memory is freed.
Apply a rate limit to avoid flooding the log in this case.

If there are several memory banks that has the same properties in CRAT,
we aggregate them into one memory bank. This cleans up memory banks on
APUs (e.g. Raven) where the CRAT reports each memory channel as a
separate bank. This only confuses user mode, which only deals with
virtual memory.

Rather than using the index variable stored in vram. If
the device fails to come back online after a resume cycle,
reads from vram will return all 1s which will cause a
segfault. Based on a patch from Thomas Martitz <[email protected]>.
This avoids the segfault, but we still need to sort out
why the GPU does not come back online after a resume.

The previous code could allow through attempts to enable more streams
than there are timing generators, in designs where the number of pipes
is greater than the number of timing generators.

count, instead of its pipe count. Also correct a typo in the error

[Why]
get_channel_status() can return 0 in returned_bytes, and report a
successful operation result. This is because it prunes the first status
byte out. This was preventing read_channel_reply() from being called
(due to the faulty condition), and consequently preventing the AUX
reply status from being set.
[How]
Fix the conditional so that it accounts for when get_channel_status()
returns 0 bytes read.
[Fixes]
Fixes possible edid read failures during S3 resume, where we are now
relying on DRM's DP AUX handling. This was an regression introduced by:

maximum, but the edid includes 4K@60 mode in cea extension block.
[How]
To enable 4K@60, need to limit BW by allowing YCbCr420 ONLY mode.
Add YCbCr420 only support for monitors that do not fully support
HDMI2.0, e.g., ASUS PA328. The YCbCr420 only support applies to
DCN, DCE112 or higher.

bug fix: phy test PLTAT is special 80bit test pattern. The 80bit
data should be hard coded within driver so that user does not
need input the deata. previous driver does not have hard coded
80 bits pattern data for PLTPAT. Other than this PLTPAT, user
has to input 80 bits pattern data. In case user input less than
10 bytes data, un-input data byte will be filled by 0x00.
