The struct assertion is failed because sparse cannot parse `#pragma pack(push, 1)` and `#pragma pack(pop)` correctly. GCC's output is still 1-byte-aligned. No harm to memory layout. The error can be filtered out by sparse-diff, but sometimes multiple lines queezed into one, making the sparse-diff thinks its a new error. I'm trying to aviod this by fixing errors.

To be able to get to the lowest power state when suspending systems with DCN3.5+, we must be in IPS before the display hardware is put into D3cold. So, to ensure that the system always reaches the lowest power state while suspending, force systems that support IPS to enter idle optimizations before entering D3cold. Reviewed-by:

We require this flag AMDGPU_GEM_CREATE_GFX12_DCC or any other kernel level GFX12 DCC flag to differentiate the DCC buffers and other pinned display buffers(which has TTM_PL_FLAG_CONTIGUOUS enabled). If we use the TTM_PL_FLAG_CONTIGUOUS flag for DCC buffers, we may over allocate for all the pinned display buffers unnecessarily that leads to memory allocation failure. Signed-off-by:

Add address alignment support to the DCC VRAM buffers. v2: - adjust size based on the max_texture_channel_caches values only for GFX12 DCC buffers. - used AMDGPU_GEM_CREATE_GFX12_DCC flag to apply change only for DCC buffers. - roundup non power of two DCC buffer adjusted size to nearest power of two number as the buddy allocator does not support non power of two alignments. This applies only to the contiguous DCC buffers. v3:(Alex) - rewrite the max texture channel caches comparison code in an algorithmic way to determine the alignment size. v4:(Alex) - Move the logic from amdgpu_vram_mgr_dcc_alignment() to gmc_v12_0.c and add a new gmc func callback for dcc alignment. If the callback is non-NULL, call it to get the alignment, otherwise, use the default. v5:(Alex) - Set the Alignment to a default value if the callback doesn't exist. - Add the callback to amdgpu_gmc_funcs. v6: - Fix checkpatch warning reported by Intel CI. v7:(Christian) - remove the AMDGPU_GEM_CREATE_GFX12_DCC flag and keep a flag that checks the BO pinning and for a specific hw generation. v8:(Christian) - move this check into gmc_v12_0_get_dcc_alignment. v9: - Fix 32bit build errors Signed-off-by: -
