Framebuffer compression is disabled when driver detects it's running in a Intel GVT-g enlightened VM, because FBC is not emulated and there is no stolen memory for a vGPU. v2: take Chris' comments: - move the code into intel_update_fbc() v4: take Tvrtko's comments: - rebase the code into intel_fbc_update() Signed-off-by: Yu Zhang <yu.c.zhang@linux.intel.com> Signed-off-by: Jike Song <jike.song@intel.com> Signed-off-by: Zhiyuan Lv <zhiyuan.lv@intel.com> --- drivers/gpu/drm/i915/intel_fbc.c | 4 ++++ 1 file changed, 4 insertions(+)
