@Jexu Inspired by the regression in Xe KMD, I'm sure the above will work together to make DG1 usable in upstream i915. |

Linux 6.13+ and LTS releases (6.1.124+, 6.6.70+ and 6.12.9+) have included the DG1 powergate fix. @Jexu @XinfengZhang Also, if I understand correctly, the The kernel 5.16+ enables GuC submission on DG1 by default, just like it does on ADL-P/ADL-N+.

This Wa is needed for using DG1 with the upstream i915 kernel. Partially fixes: intel#1415 (comment) The other part needs to be fixed on KMD side by disabling HCP_POWERGATE and MFXVDENC_POWERGATE for DG1. Unlike TGLx, DG1 doesn't support sub-pipe PG and setting these bits will cause HEVC and VP9 decoding failure.

Hi @XinfengZhang, could you spare a minute to merge this simple fix? DG1 is now available in both i915 & Xe KMD in upstream linux. See also #1920 |
