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(...);
|
|
|
|
