Re: [PATCH v3 1/1] drm/amdgpu: rework sched_list generation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Am 30.03.20 um 17:49 schrieb Nirmoy Das:
Generate HW IP's sched_list in amdgpu_ring_init() instead of
amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(),
ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary.
This patch also stores sched_list for all HW IPs in one big
array in struct amdgpu_device which makes amdgpu_ctx_init_entity()
much more leaner.

v2:
fix a coding style issue
do not use drm hw_ip const to populate amdgpu_ring_type enum

v3:
remove ctx reference and move sched array and num_sched to a struct
use num_scheds to detect uninitialized scheduler list

Please don't use a map for this, it is a 1 to 1 mapping as far as I can see which the compiler can eliminate.

The change to the amdgpu_ring_type definition looked better to me, but please make that a separate patch.
