[PATCH] drm/amdgpu: Apply flags after amdgpu_device_ip_init()

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

 



After commit 005440066f92 ("drm/amdgpu: enable gfxoff again on raven
series (v2)"), some Raven Ridge systems start to have rendering
corruption in browser [1].

Chip specific flags like cg_flags and pg_flags are applied in
amdgpu_device_ip_early_init(). For Raven Ridge, the flags may depend on
pp_feature's PP_GFXOFF_MASK bit, which can be negated in
amdgpu_device_ip_init() based on firmware information. At that time it's
already too late, since cg_flags and pg_flags are already set.

Apply flags after amdgpu_device_ip_init() and consolidate all flags to
one place, to solve the issue.
