vgt_caps is used for guest i915 driver to get the vgpu capabilities from the device model. VGT_CPAS_FULL_PPGTT is one of the capabilities type to let guest i915 dirver know that the guest i915 full ppgtt is supported by device model.
Changes since v1: - Use u32 instead of uint32_t (Joonas) - Move VGT_CAPS_FULL_PPGTT introduction to this patch and use #define instead of enum (Joonas) Signed-off-by: Tina Zhang <tina.zh...@intel.com> --- drivers/gpu/drm/i915/i915_pvinfo.h | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/gpu/drm/i915/i915_pvinfo.h b/drivers/gpu/drm/i915/i915_pvinfo.h index c0cb297..8dc0664 100644 --- a/drivers/gpu/drm/i915/i915_pvinfo.h +++ b/drivers/gpu/drm/i915/i915_pvinfo.h @@ -53,12 +53,18 @@ enum vgt_g2v_type { VGT_G2V_MAX, }; +/* + * VGT capabilities type + */ +#define VGT_CAPS_FULL_PPGTT BIT(2) + struct vgt_if { u64 magic; /* VGT_MAGIC */ uint16_t version_major; uint16_t version_minor; u32 vgt_id; /* ID of vGT instance */ - u32 rsv1[12]; /* pad to offset 0x40 */ + u32 vgt_caps; /* VGT capabilities */ + u32 rsv1[11]; /* pad to offset 0x40 */ /* * Data structure to describe the balooning info of resources. * Each VM can only have one portion of continuous area for now. -- 2.7.4 _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
