drm/amdkfd: fix interrupt spin lock

2019-01-26T08:20:39+00:00

[ Upstream commit 2383a767c0ca06f96534456d8313909017c6c8d0 ] Vega10 has multiple interrupt rings, so this can be called from multiple calles at the same time resulting in: [ 71.779334] ================================ [ 71.779406] WARNING: inconsistent lock state [ 71.779478] 4.19.0-rc1+ #44 Tainted: G W [ 71.779565] -------------------------------- [ 71.779637] inconsistent {IN-HARDIRQ-W} -> {HARDIRQ-ON-W} usage.

drm/amdkfd: Fix incorrect use of process->mm

2018-10-09T22:06:19+00:00

This mm_struct pointer should never be dereferenced. If running in a user thread, just use current->mm. If running in a kernel worker use get_task_mm to get a safe reference to the mm_struct.

drm/amdkfd: Add wavefront context save state retrieval ioctl

2018-09-27T02:09:15+00:00

Wavefront context save data is of interest to userspace clients for debugging static wavefront state. The MQD contains two parameters required to parse the control stack and the control stack itself is kept in the MQD from gfx9 onwards. Add an ioctl to fetch the context save area and control stack offsets and to copy the control stack to a userspace address if it is kept in the MQD.
