| 159 | * "PIPE_CONTROL" of the Sandy Bridge PRM volume 2 part 1: |
| 160 | * |
| 161 | * [DevSNB-C+{W/A}] Before any depth stall flush (including those |
| 162 | * produced by non-pipelined state commands), software needs to first |
| 163 | * send a PIPE_CONTROL with no bits set except Post-Sync Operation != |
| 164 | * 0. |
| 165 | * |
| 166 | * [Dev-SNB{W/A}]: Before a PIPE_CONTROL with Write Cache Flush Enable |
| 167 | * =1, a PIPE_CONTROL with any non-zero post-sync-op is required. |
| 168 | * |
| 169 | * And the workaround for these two requires this workaround first: |
| 170 | * |
| 171 | * [Dev-SNB{W/A}]: Pipe-control with CS-stall bit set must be sent |
| 172 | * BEFORE the pipe-control with a post-sync op and no write-cache |
| 173 | * flushes. |
| 174 | * |
| 175 | * And this last workaround is tricky because of the requirements on |
| 176 | * that bit. From section 1.4.7.2.3 "Stall" of the Sandy Bridge PRM |
| 177 | * volume 2 part 1: |
| 178 | * |
| 179 | * "1 of the following must also be set: |
| 180 | * - Render Target Cache Flush Enable ([12] of DW1) |
| 181 | * - Depth Cache Flush Enable ([0] of DW1) |
| 182 | * - Stall at Pixel Scoreboard ([1] of DW1) |
| 183 | * - Depth Stall ([13] of DW1) |
| 184 | * - Post-Sync Operation ([13] of DW1) |
| 185 | * - Notify Enable ([8] of DW1)" |
| 186 | * |
| 187 | * The cache flushes require the workaround flush that triggered this |
| 188 | * one, so we can't use it. Depth stall would trigger the same. |
| 189 | * Post-sync nonzero is what triggered this second workaround, so we |
| 190 | * can't use that one either. Notify enable is IRQs, which aren't |
| 191 | * really our business. That leaves only stall at scoreboard. |
