Hi All,
Sometime dmesg show this log:
[10407.720988] [drm:amdgpu_ctx_mgr_entity_fini [amdgpu]] *ERROR* ctx
00000000189dec14 is still alive
[10407.721054] [drm:amdgpu_ctx_mgr_entity_fini [amdgpu]] *ERROR* ctx
00000000189dec14 is still alive
[10407.721120] [drm:amdgpu_ctx_mgr_entity_fini [amdgpu]] *ERROR* ctx
00000000189dec14 is still alive
[10407.721187] [drm:amdgpu_ctx_mgr_entity_fini [amdgpu]] *ERROR* ctx
00000000189dec14 is still alive
[10407.721418] [drm:amdgpu_ctx_mgr_fini [amdgpu]] *ERROR* ctx 00000000189dec14
is still alive
What are the side effects?
Does this error will occur GPU hung(such as gfx timeout)?
How to fix this?
My kernel : 4.19.36
Mesa: 18.3.6
And I find that in amdgpu_ctx.c, the function:amdgpu_ctx_mgr_entity_flush
doesn't check the
ctx->refcount(the check is stopped in this patch:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=48ad368a8a3ab2fd3c2bc2ccccc6e29b1acda1bb)
,
why amdgpu_ctx_mgr_entity_fini still need check ctx->refcount?
Can i stop check ctx->refcount in amdgpu_ctx_mgr_entity_fini ?
Thanks!
