drm/amdgpu/atomfirmware: fix parsing of vram_info

2024-07-05T07:34:03+00:00

commit f6f49dda49db72e7a0b4ca32c77391d5ff5ce232 upstream. v3.x changed the how vram width was encoded. The previous implementation actually worked correctly for most boards. Fix the implementation to work correctly everywhere. This fixes the vram width reported in the kernel log on some boards.

drm/amdgpu/atomfirmware: add intergrated info v2.3 table

2024-06-16T11:47:37+00:00

commit e64e8f7c178e5228e0b2dbb504b9dc75953a319f upstream. [Why] The vram width value is 0. Because the integratedsysteminfo table in VBIOS has updated to 2.3. [How] Driver needs a new intergrated info v2.3 table too. Then the vram width value will be correct.

drm/amdgpu/atomfirmware: fix LPDDR5 width reporting

2023-06-23T19:35:16+00:00

LPDDR5 channels are 32 bit rather than 64, report the width properly in the log. v2: Only LPDDR5 are 32 bits per channel. DDR5 is 64 bits per channel Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2468 Acked-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: add drv_vram_usage_va for virt data exchange

2022-11-29T16:03:35+00:00

For vram_usagebyfirmware_v2_2, fw_vram_reserve is not used. So fw_vram_usage_va is NULL, and cannot do virt data exchange anymore. Should add drv_vram_usage_va to do virt data exchange in vram_usagebyfirmware_v2_2 case. And refine some code style checks in pre add vram reservation logic patch Signed-off-by: Tong Liu01 Acked-by: Luben Tuikov Signed-off-by: Alex Deucher
