   4 Subject: [PATCH] anv: force MEDIA_INTERFACE_DESCRIPTOR_LOAD reemit after
   5  3D->GPGPU switch
   6
   7 Seems to fix a hang in Age of Empire 4 where the HW is hung on a
   8 PIPE_CONTROL after a GPGPU_WALKER but no
   9 MEDIA_INTERFACE_DESCRIPTOR_LOAD was emitted since the switch from 3D
  10 to GPGPU.
  11
  12 This would happen in the following case :
  13
  14    vkCmdBindPipeline(COMPUTE, cs_pipeline);
  15    vkCmdDispatch(...);
  16    vkCmdBindPipeline(GRAPHICS, gfx_pipeline);
  17    vkCmdDraw(...);
  18    vkCmdDispatch(...);
