The branch main has been updated by dumbbell: URL: https://cgit.FreeBSD.org/src/commit/?id=479c61bd5f661f0e5927276c7eaea074235f6acc commit 479c61bd5f661f0e5927276c7eaea074235f6acc Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2024-12-22 16:26:49 +0000 Commit: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> CommitDate: 2025-01-31 16:00:47 +0000 linuxkpi: Add `pci_get_base_class()` [Why] This new API is used by the amdgpu DRM driver is Linux 6.7. [How] This is the same as `pci_get_class()` except that it searches a PCI device matching the base class only; the subclass is ignored.
