Merge switch_mmio_to_vgpu and switch_mmio_to_host, use delta update for mocs save restore, deal host mocs value as fixed, it won't be changed after initialization. These can save vgpu switch time to reduce CPU utilization and improve GPU performance in GVT-g with multi-VMs. Weinan Li (3): drm/i915/gvt: optimize for vGPU mmio switch drm/i915/gvt: refine mocs save restore policy drm/i915/gvt: load host render mocs once in mocs switch drivers/gpu/drm/i915/gvt/cmd_parser.c | 19 +++ drivers/gpu/drm/i915/gvt/render.c | 252 +++++++++++++++++----------------- drivers/gpu/drm/i915/gvt/trace.h | 15 +- 3 files changed, 152 insertions(+), 134 deletions(-) -- 1.9.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
