[PATCH] drm/amdkfd: use proper interrupt handling for gfx10
Jonathan Kim
jonathan.kim at amd.com
Thu Jan 13 15:42:50 UTC 2022
GFX has the following changes when handling interrupts in the KFD:
- no pasid workaround required
- SQ interrupt auto has different events
- SQ interrupt word is continguous and only has 23-bit data.
Also SH is labelled as SA and workgroup id replaces CU id.
- SQ interrupt word is continguos and only has 23 bits for err type and
err details.
- Sienna Cichlid uses a different client ID for SDMA3
(see soc15_ih_clients).
v2: forgot to add Sienna Chichlid SDMA3 client as permissible
