drm/amd/include/vega10_ip_offset: Mark _BASE structs as __maybe_unused

This patch fixes nearly 400 warnings!

These structures are too widely used in too many varying
configurations to be split-up into different headers or moved into
source files.

Instead, we'll mark them as __maybe_unused which tells the compiler
that we're aware they're being included into source files which do not
make use of them - but we've looked into it, and it's okay.

Let's tidy-up whilst were here.  Just alignment stuff.

drm/amdkfd: Put ACPI table after using it

The acpi_get_table() should be coupled with acpi_put_table() if
the mapped table is not used at runtime to release the table
mapping which can prevent the memory leak.

In kfd_create_crat_image_acpi(), crat_table is copied to pcrat_image,
and in kfd_create_vcrat_image_cpu(), the acpi_table is only used to
get the OEM information, so those two table mappings need to be released
after using it.

If the ignore_crat is set to non-zero value, it's no point getting
the CRAT table, so just move the ignore_crat check before we get the

drm/amd/amdgpu: Update VCN initizalization behvaior

- Issue:
  In the original vcn3.0 code, it assumes that the VCN's
  init_status is always 1, even after the MMSCH
  updates the header.

  This is incorrect since by default, it should be set to 0,
  and MMSCH will update it to 1 if VCN is ready.

- Fix:
  We need to read back the table header after send it to MMSCH.
  After that, if a VCN instance is not ready (host disabled it),
  we needs to disable the ring buffer as well.

drm/amd/pm: correct table_clk_vlt memory size due to replacing one-element array with flexible-array in struct phm_clock_voltage_dependency_table

Add 1 to the size passed to kzalloc after replacing one-element array.

There is a regular need in the kernel to provide a way to declare having
a dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].

Refactor the code according to the use of a flexible-array member in
struct phm_ppt_v1_mm_clock_voltage_dependency_table, instead of a
one-element array, and use the struct_size() helper to calculate the
size for the allocation.
