[Libva] [LIBVA_INTEL_DRIVER][PATCH v2 0/8] Add the 10bit VPP conversion for P010

[Zhao Yakui]

From: "Zhao, Yakui" <yakui.zhao at intel.com>

This is the patch set that tries to optimize the 10bit VPP conversion on
P010 surface. Currently it can support the 10bit VPP conversion on P010
surface.But when the size is changed, it needs the three-step conversion, which
leverage the VEBOX. (P010->NV12->scaled NV12->P010).

V1->V2: Follow Haihao's comments to update the patch set.
        1. Use the is_16bpp field
        2. Add the shader(conv_p010.g9b) into dist package
        3. Remove the unnecessary function initialization in gen75_vpp_fmt_cvt
as it is already initalized.

Zhao Yakui (8):
  Fix the incorrect sampler_state offset for INTERFACE_DESCRIPTOR_DATA
    on BDW+
  Add the 10-bit flag for MEDIA_BLOCK_RW operation on P010 surface
  Add one API to initialize MEDIA_OBJECT_WALKER parameter for video
    post-processing
  Initialize internal context based on Render ring earlier
  Initialize one 10bit-scaling gpe_context for Gen9
  VPP select the appropriate fourcc for deferred surface based on
    expected format
  Execute the 10-bit scaling for P010 surface on Gen9+
  Align coordinate/width of DST rect for 10-bit VPP conversion
