* smbios: Add length sanity checkingWarner Losh2024-07-251-3/+5
| | | | | | | | | | | D28743 was commited, reverted and then f689cb23b2782 landed before it was recommitted. However, D28743 included an extra length check. Redo that functionality so we check both the number of entries as well as the length checks for wacky data.

* smbios: handle smbios3 for arm64Andrew Gallatin2023-11-151-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | Get smbios working on arm64 where it seems to be exclusively smbios version 3.x The "interesting" thing here is that the smbios table seems to be RAM in the EFI runtime services table. This makes it owned by "ram0", and not io memory. That prevents bus_alloc_resource() from being able to claim it, since ram0 already owns it. According to jhb, this is how things are supposed to work. Eg, bus_alloc_resource() is meant to be used with IO memory, not physical memory. Following his suggestion, I converted the driver to simply use pmap_mapbios(). This is a prerequisite for getting IPMI to attach via the SSIF attachment on arm64 servers, where all IPMI that I've seen uses SSIF. Note that this change is based on initial work by Allan Jude in https://reviews.freebsd.org/D28739.
