[PATCH v2] drm/amdkfd: Have kfd driver use same PASID values from graphic driver

Xiaogang.Chen xiaogang.chen at amd.com
Mon Nov 25 15:39:14 UTC 2024


From: Xiaogang Chen <xiaogang.chen at amd.com>

Current kfd driver has its own PASID value for a kfd process and uses it to
locate vm at interrupt handler or mapping between kfd process and vm. That
design is not working when a physical gpu device has multiple spatial
partitions, ex: adev in CPX mode. This patch has kfd driver use same pasid
values that graphic driver generated which is per vm per pasid.

These pasid values are passed to fw/hardware. We do not need change interrupt
handler though more pasid values are used. Also, pasid values at log are
replaced by user process pid; pasid values are not exposed to user. Users see
their process pids that have meaning in user space.
