Subject: [PATCH] drm/i915/gvt: Rename disable_hp_work to disable GPU frequency
|
|
adjustment by default
|
|
|
|
It is expected that it doesn't adjust the GPU frequency by default when
|
|
the VGPU workload is submitted.
|
|
The parameter of disable_hp_work is renamed so that the GPU frequency
|
|
is enabled explicitly.
