drm/amdkfd: Skip packet submission on fatal error

2024-02-26T16:14:31+00:00

If fatal error is detected, packet submission won't go through. Return error in such cases. Also, avoid waiting for fence when fatal error is detected. Signed-off-by: Lijo Lazar Reviewed-by: Asad Kamal Signed-off-by: Alex Deucher

drm/amdkfd: Introduce kfd_node struct (v5)

2023-06-09T13:42:27+00:00

Introduce a new structure, kfd_node, which will now represent a compute node. kfd_node is carved out of kfd_dev structure. kfd_dev struct now will become the parent of kfd_node, and will store common resources such as doorbells, GTT sub-alloctor etc. kfd_node struct will store all resources specific to a compute node, such as device queue manager, interrupt handling etc. This is the first step in adding compute partition support in KFD. v2: introduce kfd_node struct to gc v11 (Hawking) v3: make reference to kfd_dev struct through kfd_node (Morris) v4: use kfd_node instead for kfd isr/mqd functions (Morris) v5: rebase (Alex) Signed-off-by: Mukul Joshi Tested-by: Amber Lin Reviewed-by: Felix Kuehling Signed-off-by: Hawking Zhang Signed-off-by: Morris Zhang Signed-off-by: Alex Deucher

drm/amdkfd: Eliminate unnecessary kernel queue function pointers

2019-12-05T21:24:36+00:00

Up to this point, those functions are all the same for all ASICs, so no need to call them by functions pointers. Removing the function pointers will greatly increase the code readablity. If there is ever need for those function pointers, we can add it back then. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Eliminate ops_asic_specific in kernel queue

2019-11-19T14:47:17+00:00

The ops_asic_specific function pointers are actually quite generic after using a simple if condition. Eliminate it by code refactoring. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Merge CIK kernel queue functions into VI

2019-11-19T14:47:02+00:00

The only difference that CIK kernel queue functions are different from VI is avoid allocating eop_mem. We can achieve that by using a if condition. Signed-off-by: Yong Zhao Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdkfd: Use kernel queue v9 functions for v10

2019-11-13T20:29:45+00:00

The kernel queue functions for v9 and v10 are the same except pm_map_process_v* which have small difference, so they should be reused. This eliminates the need of reapplying several patches which were applied on v9 but not on v10, such as bigger GWS and more than 2 SDMA engine support which were introduced on Arcturus.
