The branch main has been updated by dumbbell: URL: https://cgit.FreeBSD.org/src/commit/?id=65dc0e9071a5ea206d6fbf070c974ebcfdea3680 commit 65dc0e9071a5ea206d6fbf070c974ebcfdea3680 Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2026-04-22 16:23:16 +0000 Commit: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> CommitDate: 2026-04-30 11:40:01 +0000 linuxkpi: Define `VFM_*()` macros in <asm/cpu_device_id.h> They use another set of constants and macros in <asm/intel-family.h>. All these macros are defined regardless of the architecture, even though they are specific to x86. Perhaps we should restrict them using #ifdefs. The amdgpu DRM driver started to used `VFM_MODEL()` and the `INTEL_*LAKE*` constants in Linux 6.12.x.
