Move fw fetching to init phase and do it separately per guc/huc struct. v2: don't forget to move wopcm_init - Michele v3: fetch in init_misc phase - Michal Signed-off-by: Michal Wajdeczko Cc: Daniele Ceraolo Spurio Cc: Michel Thierry Reviewed-by: Michel Thierry #2 Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20180628141522.62788-2-michal.wajdeczko@intel.com --- diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index 5a9cae604e2b..8954db6ab083 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -5459,13 +5459,13 @@ int i915_gem_init(struct drm_i915_private *dev_priv) if (ret) return ret;
