+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(...);

+Subject: [PATCH] intel/fs: always mask the bottom bits of the sampler extended
+ descriptor
+
+Fixes a hang in Age Of Empire 4. The HW is hang with the sampler input
+unit busy. Replaying on simulation showed the extended message length
+in the extended descriptor is invalid. Since the Anv ensures the input
+is correct in anv_surface_state_to_handle(), the likely reason for
+this issue is the use of VK_VALVE_mutable_descriptor_type and the
+application leaving a previous value for a different descriptor type.
