Subject: [PATCH] anv: force MEDIA_INTERFACE_DESCRIPTOR_LOAD reemit after
3D->GPGPU switch
Seems to fix a hang in the following titles :
- Age of Empire 4
- Monster Hunter Rise
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(...);
