PHYS_TO_DMAP: Return a void * instead of a vm_offset_t

2026-04-23T17:05:54Z

Add a new PHYS_TO_DMAP_ADDR that still returns an address for use in places that only need an address and not a pointer. Effort: CHERI upstreaming Reviewed by: kib Sponsored by: AFRL, DARPA Pull Request: https://github.com/freebsd/freebsd-src/pull/2068

efidev: add support for memory attribute

2025-07-22T04:45:29Z

The EFI_PROPERTIES_TABLE has been deprecated in the UEFI specification. It is now replaced by the EFI_MEMORY_ATTRIBUTES_TABLE, which provides a new header and data format for describing memory region attributes.

efi: Move to using efi_guid_t in ioctl definitions

2025-05-01T17:53:40Z

Start using efi_guid_t instead of struct uuid in the ioctl definitions. These are binarily the same, but have different structure definitions. EFI prefers this form, and to allow more sharing with EDK2, make this slight addition. I've not really defined new IOCTLs for this. They are the same size, but I have defined new function. Also fix in-kernel uses of uuid to efi_guid_t for anything related to ioctl. Sponsored by: Netflix Reviewed by: tsoome, kib Differential Revision: https://reviews.freebsd.org/D50057

efi: Use EDK2 EFI_GUID instead of sturct uuid

2025-05-01T17:53:28Z

So, while struct uuid and EFI_GUID are quite similar (they are the same size, they have the same binary representation, etc), they aren not identical. Speciifcally, the UUID and GUID defines are slightly different and can't be swapped one for the other. Start to use EFI_GUID for all EFI tables. This will allow increased sharing with the boot laoder that already uses EDK2 variants as well as using the possibility to use the EDK2 headers we've already imported more easily.

sys: make the kernel metadata pointer global

2025-01-24T21:25:51Z

The way we got the kernel metadata pointer was by calling preload_search_by_type with one of the following three: "elf kernel", "elf32 kernel" and "elf64 kernel". Which one(s) we used wasn't consistent though. Sometimes we would only try "elf kernel", and other times we would try one of the latter two if the first failed. However, the loader only ever sets "elf kernel" as the kernel type. Now, the kmdp is a global, preload_kmdp, and it's initialized using preload_initkmdp in machdep.c (or machdep_boot.c on arm/64). preload_initkmdp takes a single boolean argument that tells us whether not finding the kmdp is fatal or not.
