From: Alex Deucher Date: Wed, 5 Jul 2023 21:57:59 +0000 (-0400) Subject: drm/amdgpu/gfx10: move update_spm_vmid() out of rlc_init() X-Git-Tag: v6.6.7~1918^2~20^2~173 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=95b88ea1af4b4c0de3f151347605dbc6734e6cb2;p=platform%2Fkernel%2Flinux-starfive.git drm/amdgpu/gfx10: move update_spm_vmid() out of rlc_init() rlc_init() is part of sw_init() so it should not touch hardware. Additionally, calling the rlc update_spm_vmid() callback directly invokes a gfx on/off cycle which could result in powergating being enabled before hw init is complete. Split update_spm_vmid() into an internal implementation for local use without gfxoff interaction and then the rlc callback which includes gfxoff handling.
