treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

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: Skip SDMA suspend during mode-2 reset

2025-10-13T18:14:33+00:00

For SDMA IP versions >= v4.4.2, firmware will take care of quiescing SDMA before mode-2 reset. Signed-off-by: Lijo Lazar Reviewed-by: Asad Kamal Signed-off-by: Alex Deucher

drm/amdgpu: Suspend IH during mode-2 reset

2025-06-18T16:19:18+00:00

On multi-aid SOCs, there could be a continuous stream of interrupts from GC after poison consumption. Suspend IH to disable them before doing mode-2 reset. This avoids conflicts in hardware accesses during interrupt handlers while a reset is ongoing. Signed-off-by: Lijo Lazar Reviewed-by: Asad Kamal Signed-off-by: Alex Deucher

drm/amdgpu: Prefer RAS recovery for scheduler hang

2024-12-10T15:26:46+00:00

Before scheduling a recovery due to scheduler/job hang, check if a RAS error is detected. If so, choose RAS recovery to handle the situation. A scheduler/job hang could be the side effect of a RAS error. In such cases, it is required to go through the RAS error recovery process. A RAS error recovery process in certains cases also could avoid a full device device reset. An error state is maintained in RAS context to detect the block affected. Fatal Error state uses unused block id. Set the block id when error is detected. If the interrupt handler detected a poison error, it's not required to look for a fatal error. Skip fatal error checking in such cases. Signed-off-by: Lijo Lazar Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: Add init level for post reset reinit

2024-11-20T15:03:05+00:00

When device needs to be reset before initialization, it's not required for all IPs to be initialized before a reset. In such cases, it needs to identify whether the IP/feature is initialized for the first time or whether it's reinitialized after a reset. Add RESET_RECOVERY init level to identify post reset reinitialization phase. This only provides a device level identification, IP/features may choose to track their state independently also.
