44	What are the flags? Are they defined somewhere? Or are they internal to AMDGPU?

dumbbell added inline comments.

sys/compat/linuxkpi/common/include/linux/ioport.h
44	The flags the DRM driver uses are already defined in `<linux/pci.h>`. #define IORESOURCE_MEM (1 << SYS_RES_MEMORY) #define IORESOURCE_IO (1 << SYS_RES_IOPORT) #define IORESOURCE_IRQ (1 << SYS_RES_IRQ) They should be defined in `<linux/ioport.h>` too, but we can’t include this header in `<linux/pci.h>`.

This will need a __FreeBSD_version bump.
