drm/amdkfd: Add domain parameter to alloc kernel BO

2026-01-14T19:28:59+00:00

To allocate kernel BO from VRAM domain for MQD in the following patch. No functional change because kernel BO allocate all from GTT domain. Rename amdgpu_amdkfd_alloc_gtt_mem to amdgpu_amdkfd_alloc_kernel_mem Rename amdgpu_amdkfd_free_gtt_mem to amdgpu_amdkfd_free_kernel_mem Rename mem_kfd_mem_obj gtt_mem to mem Signed-off-by: Philip Yang Reviewed-by: Kent Russell Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: kfd driver supports hot unplug/replug amdgpu devices

2026-01-14T19:28:49+00:00

This patch allows kfd driver function correctly when AMD gpu devices got unplug/replug at run time. When an AMD gpu device got unplug kfd driver gracefully terminates existing kfd processes after stops all queues by sending SIGBUS to user process. After that user space can still use remaining AMD gpu devices. When all AMD gpu devices at system got removed kfd driver will not response new requests. Unplugged AMD gpu devices can be re-plugged. kfd driver will use added devices to function as usual. The purpose of this patch is having kfd driver behavior as expected during and after AMD gpu devices unplug/replug at run time.

drm/amdgpu: reduce the full gpu access time in amdgpu_device_init.

2025-12-08T18:56:38+00:00

[Why] function "devm_memremap_pages" in function "kgd2kfd_init_zone_device", sometimes cost too much time. [How] move the function "kgd2kfd_init_zone_device" after release full gpu access(amdgpu_virt_release_full_gpu). v2: improve the coding style.

drm/amdgpu: update the functions to use amdgpu version of hmm

2025-10-13T18:14:36+00:00

At times we need a bo reference for hmm and for that add a new struct amdgpu_hmm_range which will hold an optional bo member and hmm_range. Use amdgpu_hmm_range instead of hmm_range and let the bo as an optional argument for the caller if they want to the bo reference to be taken or they want to handle that explicitly.

drm/amdgpu/amdkfd: Avoid a couple hundred -Wflex-array-member-not-at-end warnings

2025-09-02T21:36:20+00:00

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are getting ready to enable it, globally. Move the conflicting declarations to the end of the corresponding structures. Notice that `struct dev_pagemap` is a flexible structure, this is a structure that contains a flexible-array member. struct dev_pagemap always has room for at least one range. amdgpu only uses a single range. Therefore no change are needed to the allocation of struct amdgpu_device. Fix 283 of the following type of warnings: 283 drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h:111:28: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Signed-off-by: Gustavo A.

For the suspend and resume process, exclusive access is not required. Therefore, it can be moved out of the full access section to reduce the duration of exclusive access. v3: Move suspend processes before hardware fini.
