We have encountered performance hot issues in vce module. Cpu occupancy rate
has been in the alloc_vmap_area function.
We found that calling the alloc_vmap_area function mainly occurs in the
amdgpu_cs_ib_vm_chunk function. So we removed the main loop judgment logic of
amdgpu_cs_ib_vm_chunk.
as follows .
- if (p->ring->funcs->parse_cs || p->ring->funcs->patch_cs_in_place) {
+ if (0)
If we don't delete, vce will be very slow.
Is this the fundamental way to solve the problem? Or there are other ways to
solve the problem？
3q very much.
