* Don't sync the I/D caches when they are coherentAndrew Turner2021-12-201-1/+1
| | | | | | | | | | | | In the arm64 loader we need to syncronise the I and D caches. On some newer CPUs the I and D caches are coherent so we don't need to perform these operations. While here remove the arguments to cpu_inval_icache as they are unneeded. Reported by: cperciva Tested by: cperciva Sponsored by: Innovate UK
* loader.efi: Do not use as frame buffer BLT-only GOPs.Alexander Motin2021-12-161-4/+16
| | | | | | | | | | | | Kernel needs physical frame buffer address and size, which Block Transfer-only Graphics Output Protocol instances do not have. Some recent ASUS boards like PRIME Z690M-PLUS D4 and PRIME H570-Plus report two GOPs, out of which the second one support ConOut protocol, that made it preferable, but is BLT-only, that made console unusable.

| | | | | | | | | | | | | | | | Booting on an EC2 c5.xlarge instance, this reduces the number of I/Os performed from 609 to 432, reduces the total number of blocks read from 61963 to 60797, and reduces the time spent in the loader by 39 ms. Note that b4cb3fe0e39a allowed the bcache to be retained for most of the boot process, but relies on mounting filesystems; this commit allows the bcache to be retained at the start of the boot process, before the root filesystem has been located.

For now, by default the old mode of copying kernel to 2M phys is retained. It is going to be changed in several weeks. On amd64, add some slop to the staging area to satisfy both requirements of the kernel startup allocator, and to have space for minor staging data increase after the final size is calculated.

Include cross reference for the preferred method described in efibootmgr(8) as well as cross links in both gptboot(8) and gptboot.efi(8) to the other. This man page was heavily copied from the gptboot.8 man page by Warren Block. They are different enough to need separate man pages for clarity, but there's enough similarity that I worry about the duplication. In the really long term, gptboot(8) will disappear, so having the same info here will help when that day comes. In the short to medium term, the information is likely to not change in gptboot(8) and any changes to gptboot.efi(8) will be easier to make in a separate copy. loader.efi(8) needs a complete rewrite from scratch, otherwise I'd have referenced gptboot.efi(8) from there.

| | | | | | | | | | | | | | | | | | | | Add some basic multiboot2 infrastructure to the EFI loader in order to be capable of booting a FreeBSD/Xen dom0 when booted from UEFI. Only a very limited subset of the multiboot2 protocol is implemented in order to support enough to boot into Xen, the implementation doesn't intend to be a full multiboot2 capable implementation. Such multiboot2 functionality is hooked up into the amd64 EFI loader, which is the only architecture that supports Xen dom0 on FreeBSD. The options to boot a FreeBSD/Xen dom0 system are exactly the same as on BIOS, and requires setting the xen_kernel and xen_cmdline options in loader.conf.
