+Subject: [PATCH] anv: force MEDIA_INTERFACE_DESCRIPTOR_LOAD reemit after
+ 3D->GPGPU switch
+
+Seems to fix a hang in Age of Empire 4 where the HW is hung on a
+PIPE_CONTROL after a GPGPU_WALKER but no
+MEDIA_INTERFACE_DESCRIPTOR_LOAD was emitted since the switch from 3D
+to GPGPU.
+
+This would happen in the following case :
+
+   vkCmdBindPipeline(COMPUTE, cs_pipeline);
+   vkCmdDispatch(...);
+   vkCmdBindPipeline(GRAPHICS, gfx_pipeline);
+   vkCmdDraw(...);
+   vkCmdDispatch(...);
+
