e1b385726f drm/amd/display: Add additional checks for PSP footer size
[WHY & HOW]
Newer ASICs have different PSP footer sizes which lead to driver
failing to locate the DMCUB FW meta info, which in turn causes
improper DMCUB FW loading and causes DMCUB to crash.

Add support for custom PSP footer sizes and check 512B by default
as well.

c7062be338 drm/amd/display: Correct DSC padding accounting
[WHY]
- After the addition of all OVT patches, DSC padding was being accounted
  for multiple times, effectively doubling the padding
- This caused compliance failures or corruption

[HOW]
- Add padding to DSC pic width when required by HW, and do not re-add
  when calculating reg values
- Do not add padding when computing PPS values, and instead track padding
  separately to add when calculating slice width values

a574f53ed5 drm/amd/display: Permit DC_FP_START/END only in non-FP compilation units
[WHAT]
Test the existing CPP macro _LINUX_FPU_COMPILATION_UNIT, which is set
when building source files that are permitted to use floating point,
in the implementation of DC_FP_START/END so that those are only usable
in non-FP code. This is a requirement of the generic kernel mode FPU
API, as some architectures (i.e., arm64) cannot safely enable FP codegen
in arbitrary code.

d8c2c6c33d drm/amdgpu: Map/Unmap MMIO_REMAP as BAR register window; add TTM sg helpers; wire dma-buf
MMIO_REMAP (HDP flush page) exposes a hardware MMIO register window via
a PCI BAR; there are no struct pages backing it (not normal RAM).  But
when one device shares memory with another through dma-buf, the receiver
still expects a delivery route—a list of DMA-able chunks—called an
sg_table. For the BAR window, we can’t (no pages!), so we instead create
a one-entry list that points directly to the BAR’s physical bus address
and tell DMA: “use this I/O span.” - A single, contiguous byte range on
the PCI bus (start DMA address + length)). That’s why we map it with
dma_map_resource() and set sg_set_page(..., NULL, ...). Perform DMA
reads/writes directly to that range so we build an sg_table from a BAR
physical span and map it with dma_map_resource().

This patch centralizes the BAR-I/O mapping in TTM and wires dma-buf to
it:

Add amdgpu_ttm_mmio_remap_alloc_sgt() /
amdgpu_ttm_mmio_remap_free_sgt(). They walk the TTM resource via
amdgpu_res_cursor, add the byte offset to adev->rmmio_remap.bus_addr,
build a one-entry sg_table with sg_set_page(NULL, …), and map/unmap it
with dma_map_resource().

In dma-buf map/unmap, if the BO is in AMDGPU_PL_MMIO_REMAP, call the new
helpers.

Single place for BAR-I/O handling: amdgpu_ttm.c in
amdgpu_ttm_mmio_remap_alloc_sgt() and ..._free_sgt().
No struct pages: sg_set_page(sg, NULL, cur.size, 0); inside
amdgpu_ttm_mmio_remap_alloc_sgt().
Minimal sg_table: sg_alloc_table(*sgt, 1, GFP_KERNEL); inside
amdgpu_ttm_mmio_remap_alloc_sgt().
Hooked into dma-buf: amdgpu_dma_buf_map()/unmap() in amdgpu_dma_buf.c
call these helpers for AMDGPU_PL_MMIO_REMAP.

v2: squash in fix for set/get tiling

de8955508b drm/amdgpu/ttm: Pin 4K MMIO_REMAP Singleton BO at Init v2
MMIO_REMAP (HDP flush page) is a hardware I/O window exposed via a PCI
BAR.  It must not migrate or be evicted.

Allocate a single 4 KB GEM BO in AMDGPU_GEM_DOMAIN_MMIO_REMAP during TTM
initialization when the hardware exposes a remap bus address and the
host page size is <= 4 KiB. Reserve the BO and pin it at the TTM level
so it remains fixed for its lifetime. No CPU mapping is established
here.

On teardown, reserve, unpin, and free the BO if present.

This prepares the object to be shared (e.g., via dma-buf) without
triggering placement changes or no CPU-access migration

v2: Added extra NULL checks
