Hi Jani: Previously when I sent a pull request, it will be top of a tag in drm-intel-next. The following patches move the DMC related registers, which is used by GVT-g into intel_dmc_regs.h and it is not included in the latest tag. commit 9c67d9e84c7d4a3a2371a54ee2dddc4699002000 Author: Jani Nikula <jani.nikula@xxxxxxxxx> Date: Wed Mar 30 14:34:17 2022 +0300 drm/i915/dmc: split out dmc registers to a separate file Clean up the massive i915_reg.h a bit with this isolated set of registers. v2: Remove stale comment (Lucas) Signed-off-by: Jani Nikula <jani.nikula@xxxxxxxxx> Reviewed-by: Lucas De Marchi <lucas.demarchi@xxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20220330113417.220964-3-jani.nikula@xxxxxxxxx If I still sent the pull request based on the latest tag, after the pull got merged, the compiling of the GVT-g module will be broken, as a new header needs to be included. Can I sent my pull request not based on a tag in drm-intel-next, just the latest drm-intel-next? Thanks, Zhi.
