32a92f8c89 Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Moved virtual_link_encoder and virtual_stream_encoder to dc/dio/virtual/.
Moved virtual_link_hwss to dc/link/hwss/ and renamed to link_hwss_virtual.
Removed dc/virtual/ directory.

edae98a2bd drm/amd/display: Add DSC padding for OVT Support
[Why]
-Certain OVT timings require DSC configurations which divide the
horizontal active unevenly across DSC slices
-DSC slices must be even, so padding needs to be added to the active
to make this possible
-The pixel clock of the HW now needs to be increased to accommodate
the extra padded pixels
-To keep the line time the same, the blank of the HW timing needs to
be increased as well

[How]
-Calculate h_active padding, h_total padding, and pixel clock based
off of the original OVT timing and DSC calculations
-Store these values in the pipe and program HW with these modifications
-Added general support for cases where DSC slice config does not evenly
split the horizontal active by fixing some slice width calculations
-Updated PPS calculations for these cases

d7b618bc41 drm/amd/display: Refactor DSC cap calculations
[WHY]
DSC block level should only be responsible for reporting single DSC
instance capabilities. Factoring in ODM combine requirements should be
handled in dc_dsc.c. Both components should acquire clocks from clk_mgr
to determine throughput capabilities instead of relying on hard coded
values as these can differ by SoC and SKU.

[HOW]
1) Add dsc_get_single_enc_caps to acquire single DSC instance
    capabilities (replacing dsc_get_enc_caps), factoring in DSCCLK
2) add build_dsc_enc_caps to combine single DSC instance capabilities
3) account for max pixel rate per pipe (DISPCLK) when calculating
    minimum slice count

c7c703e433 drm/amd/display: Ensure correct GFX tiling info passed to DML
[Why]
To ensure DML validation receives the correct tiling information,
such as swizzle mode or array mode, based on the active GFX format

[How]
- For new GFX format passed swizzle_mode to DML.
- For legacy GFX format passed array_mode to DML.
- Dynamically determined the appropriate tiling info based on the
  active GFX format.

[Description]
This commit ensures that the correct GFX tiling information is passed
to DML. Depending on the active GFX format, the appropriate tiling info
is passed to DML. This change accommodates the different GFX formats
supported by latest platforms, ensuring compatibility and proper
DML validation.
