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/amdkfd: No need to suspend whole MES to evict process

2026-01-14T19:28:59Z

Each queue of the process is individually removed and there is not need to suspend whole mes. Suspending mes stops kernel mode queues also causing unnecessary timeouts when running mixed work loads Fixes: 079ae5118e1f ("drm/amdkfd: fix suspend/resume all calls in mes based eviction path") Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4765 Signed-off-by: Harish Kasiviswanathan Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdkfd: fix a memory leak in device_queue_manager_init()

If dqm->ops.initialize() fails, add deallocate_hiq_sdma_mqd() to release the memory allocated by allocate_hiq_sdma_mqd(). Move deallocate_hiq_sdma_mqd() up to ensure proper function visibility at the point of use.

drm/amdgpu: Update MES VM_CNTX_CNTL for XNACK off for GFX 12.1

2025-12-10T22:39:09Z

Currently, we do not turn off retry faults in VM_CONTEXT_CNTL value when passing it to MES if XNACK is off. This creates a situation where XNACK is disabled in SQ but enabled in UTCL2, which is not recommended. As a result, turn off/on retry faults in both SQ and UTCL2 when passing vm_context_cntl value to MES if XNACK is disabled/enabled.
