treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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 *". Signed-off-by: Kees Cook

drm/amdgpu: Fix the issue of missing ras message on sriov host

drm/amdgpu: load RAS bad page from PMFW in page retirement

By polling, poll ACA bank count to ensure that valid ACA bank reg info can be obtained v2: add corresponding delay before send msg to SMU to query mca bank info (Stanley) v3: the loop cannot exit. (Thomas) v4: remove amdgpu_aca_clear_bank_count. (Kevin) v5: continuously inject ce. If a creation interruption occurs at this time, bank reg info will be lost.

drm/amdgpu: Use active umc info from discovery

2025-02-13T02:02:56Z

There could be configs where some UMC instances are harvested. This information is obtained through discovery data and populated in umc.active_mask. Avoid reassigning this as AID mask, instead use the mask directly while iterating through umc instances. This is to avoid accesses to harvested UMC instances. v2: fix warning (Alex) Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: correct the calculation of RAS bad page

2024-12-10T15:26:51Z

After the introduction of NPS RAS, one bad page record on eeprom may be related to 1 or 16 bad pages, so the bad page record and bad page are two different concepts, define a new variable to store bad page number. Signed-off-by: Tao Zhou Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: parse legacy RAS bad page mixed with new data in various NPS modes

2024-12-10T15:26:48Z

All legacy RAS bad pages are generated in NPS1 mode, but new bad page can be generated in any NPS mode, so we can't use retired_page stored on eeprom directly in non-nps1 mode even for legacy data. We need to take different actions for different data, new data can be identified from old data by UMC_CHANNEL_IDX_V2 flag.
