| | | | | | | | | | | | | 9600 was a standard baud rate decades ago, but 115200 is now more common so choose defaults that are useful to the largest number of users. Note that boot0sio does not support rates above 9600 so it remains unchanged.

* stand: Document EFI consolesWarner Losh2022-09-011-8/+180
| | | | | | | | | | | | | | Document how EFI consoles work, at least on x86. There's a number of weird quirks and limitations that are generally known, but not documented until now. Include information on how EFI decides what the defualt console is, how to set it and how to cope with common situations. Note limitations and mismatch between ACPI (which uses UID to identify a device) and our console code (which uses a raw address) and explain why we can't translate between them in the loader.

* loader: create separate man pages for each of the loadersWarner Losh2021-09-295-1064/+911
| | | | | | | | | | | | | | | Create a man page per loader. Loader(8) will have information common to all of them, while loader_${INTERP}(8) will have information relevant to that specific loader. Rewrite loader(8) to give an overview and point to the appropriate man page. Rewrite each of the loader_${INTER}(8) man pages to contain only the relevant information to that loader. Put all the common commands, environment variables, etc in loader_simp(8) and refernce that from the loader_lua or loader_4th man pages. The loader_lua(8) could use more details about the Lua integration. Additional organization may be benefitial. Sponsored by: Netflix Differential Revision: https://reviews.freebsd.org/D31340
* loader: Set twiddle globaldiv to 16 by defaultColin Percival2021-09-282-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | Booting FreeBSD on an EC2 c5.xlarge instance, the loader "twiddles" 810 times over the course of 510 ms, a rate of 1.59 kHz. Even accepting that many systems are slower than this particular VM and will take longer to boot (especially if using spinning-rust disks), this seems like an unhelpfully large amount of twiddling when compared to the ~60 Hz frame rate of many displays; printing the twiddles also consumes roughly 10% of the boot time on the aforementioned VM. Setting the default globaldiv to 16 dramatically reduces the time spent printing twiddles to the console while still twiddling at roughly 100 Hz; this should be ample even for systems which take longer to boot and consequently twiddle slower. Note that this can adjusted via the twiddle_divisor variable in loader.conf, but that file is not processed until nearly halfway through the loader's runtime.

* loader: Create loader_simp(8) to document simple version of loaderWarner Losh2021-07-142-0/+763
| | | | | | | | | | loader_simp is a much simplified version of loader that will process a linear sequence of commands from loader.rc. It has neither Forth nor Lua built in and is much smaller.

| | | | | | | | | | | | | Until now, the boot image can be embedded into the loader with /sys/tools/embed_mfs.sh, and memory disk (MD) is already supported in loader source. But due to memory disk (MD) driver isn't registered to the loader yet, the boot image can't be boot from embedded memory disk.

* gptboot.efi: Add man pageWarner Losh2021-04-061-2/+12
| | | | | | | | | | | | | | | | | | | | | | Add a man page for gptboot.efi. Describe when and how to use this as it differs from the BIOS cases. 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.
