* edk2: Move ProcessorBind.h to contrib/edk2Warner Losh2025-11-161-3/+0
| | | | | | | | | | | | | | | | | | | Have our own ProcessorBind.h. It just includes sys/efi-edk2.h, but undefines TRUE, FALSE and MAC. The first two are from acpica and are redefined to something almost the same. MAC is a global option that, well, interferes with using EDK2, dangit. I suppose I should redefine it after, but I don't think you can save the value of a pre-processor variable. This breaks a little with the tradition of having this in a seprate directory and using build magic. However, the build is already magical enough and having this here makes things less magical. Also, EDK2 puts this in a processor specific directory, so we won't have conflicts (they need it there since they run on more processors than we do: we can just include sys/efi-edk2.h which covers the smallar variance we have in processors).

* efi: Move edk2 compat defines to sys/efi-edk2.hWarner Losh2025-11-167-123/+2
| | | | | | | | | | | | | | | | | | | | Create efi-freebsd.h, which is safe to include from the FreeBSD context (all of userland, except the small bits we share with edk2 and the kernel). This defines anything that we need. At the moment, it just includes NULL definitions. Create efi-edk2.h, which is approximately ProcessorBind.h from edk2 that we can include in FreeBSD compontents that are re-using edk2 components (bits of the boot laoder, and libefi*). Update the efi_gid definitions to match edk2 better. Add this file to badfiles.inc, since we can't write it in a way that's compatible. This is copied from the old efi-osdep.h. This has to be done in one commit that's bigger than I like since we can't easily move things piecemeal around they are so inter-related.

| | | | | | | | | | | | | uuid_table was the linux name. When libefivar was started, I tried to make it compatible with Linux. However, that's no longer relevant: (a) little to no Linux code was subsequently ported and (b) Linux compat has eroded. This erodes it a bit more to cope with the uuid_t -> efi_guid_t changes. This also moves a couple of functions around to reduce copying and updates consumers for the visible parts of this change.

| | | | | | | | | | In these cases, memcmp is a perfectly fine substitute for the uuid functions. We don't need checking to make sure the uuids are good, we know the pointers are non-ULL, etc. memcmp will reduce the number of places we need to know these are actually UUIDs, or similar.

However, the only way to find that is to iterate through all the geoms that belong to the glabel geom class, looking for those geoms with the same name as the provider with the right efimedia. Do this in a way that caches glabel class, and allows for it to be absent. Tighten the filter for mounted filesystems to only look for the ones that are mounted on /dev/.. since the rest of the code assumes that.

* libefivar: Handle USBxxx device path when optional para is not specifiedJose Luis Duran2022-02-271-5/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | According to UEFI spec, for the Messaging Device Path with USB Class SubType, some paras are optional in the text device path. Take UsbClass(VID,PID,Class,SubClass,Protocol) for example, The VID is an integer between 0 and 65535 and is optional. The default value is 0xFFFF. The PID is an integer between 0 and 65535 and is optional. The default value is 0xFFFF. The Class is an integer between 0 and 255 and is optional. The default value is 0xFF. The SubClass is an integer between 0 and 255 and is optional. The default value is 0xFF. The Protocol is an integer between 0 and 255 and is optional. The default value is 0xFF. So if any the optional para is not specified in the text device, we should set related para in the node structure to default value. This commit is to do the enhancement for USB Class device path when optional para is not specified.
