| This fixes a glamore corruption issue on the HoneyComb and by | |
| internet reports should also fix problems seen on Huaweii | |
| Kunpeng hardware. | |
| The root cause of the corruption needs to be worked out, but |

| Subject: [PATCH] radeonsi: Temporary patch to fix corruption with persitent | |
| buffers | |
| Until further debugging is done set kernel_flushes_hdp_before_ib to | |
| false so persistent buffers are allocated from GTT memory. I have | |
| an open issue for this in mesa that perhaps this should become a | |
| runtime DRI option that can be enabled. |
