* lualoader: fix lua-lint runKyle Evans2020-12-171-1/+1
| | | | | | | | | | | luacheck rightfully complains that i is unused in the show-module-options loop at the end (it was used for some debugging in the process). We've added a new pager module that's compiled in, so declare that as an acceptable global. Notes: svn path=/head/; revision=368729
* lualoader: cli: provide a show-module-options loader commandKyle Evans2020-12-174-2/+91
| | | | | | | | | | | | | This effectively dumps everything lualoader knows about to the console using the libsa pager; that particular lua interface was added in r368591. A pager stub implementation has been added that just dumps the output as-is as a compat shim for older loader binaries that do not have lpager. This stub should be moved into a more appropriate .lua file if we add anything else that needs the pager. Notes: svn path=/head/; revision=368728

* loader: Ignore the .interp section on RISC-VJessica Clarke2020-12-141-0/+1
| | | | | | | | | | | | | | Without this we risk having the .interp section be placed earlier in the file and mess with section offsets; in particular it has been seen to be placed at the start of the file and cause the PE/COFF header to not be at address 0.

* stand: liblua: add a pager moduleKyle Evans2020-12-124-1/+92
| | | | | | | | | | | | | | | This is nearly a 1:1 mapping of the pager API from libsa. The only real difference is that pager.output() will accept any number of arguments and coerce all of them to strings for output using luaL_tolstring (i.e. the __tostring metamethod will be used). The only consumer planned at this time is the upcoming "show-module-options" implementation. MFC after: 1 week Notes: svn path=/head/; revision=368591

Previously we used the adr instruction to find this address, however this instruction is limited to +/- 1MiB.

* lualoader: improve the design of the brand-/logo- mechanismKyle Evans2020-10-047-138/+171
| | | | | | | | | | | | | | | | | | | | | | | | In the previous world order, any brand/logo was forced to pull in the drawer and call drawer.add{Brand,Logo} with the name their brand/logo is taking and a table describing it. In the new world order, these files just need to return a table that maps out graphics types to a table of the exact same format as what was previously being passed back into the drawer. The appeal here is not needing to grab a reference back to the drawer module and having a cleaner data-driven looking format for these. The format has been renamed to 'gfx-*' prefixes and each one can provide a logo and a brand. drawer.addBrand/drawer.addLogo will remain in place until FreeBSD 13, as there's no overhead to them and it's not yet worth the break in compatibility with any pre-existing brands and logos.

Useful for installs where the default selected may not be quite what you want, or when you are running a dual setup and need to toggle over to the other console being primary. The 'c'/'C' keys will do the cycling through the consoles. Note: you'll still have to drop into the loader to set details about serial consoles.

* Fix video on PCI heuristicWarner Losh2020-09-281-2/+4
| | | | | | | | | | | | | | | | | | The video on PCI heuristic was broken. It was supposed to infer a video device when the last element of the path was a PCI DEVICE PATH node. However, the last node in the device path is an END node, so this heuristic never fired. This leads, among other things, to bhyve only producing output in the serial connection once we leave the boot loader. This restores the dual headed boot on bhyve + UEFI (as we did in 11.2), but will favor serial in the absence of other config which may be a change from 11.2.

While there is no way at that stage to test, the more logical approach would be to pick first matching pool. This patch is assuming we do pass pool guid pointer with guid value 0, this will help us to determine, if the guid value is already set or not.

By default, the bootonce setting is reset on attempt to boot and the next boot will use previously active BE. By setting zfs_bootonce_activate="YES" in rc.conf, the bootonce BE will be set permanently active. bootonce dataset name is recorded in boot pool labels, bootenv area. in case of nextboot, the nextboot_enable boolean variable is recorded in freebsd:nvstore nvlist, also stored in boot pool label bootenv area. On boot, the loader will process /boot/nextboot.conf if nextboot_enable is "YES", and will set nextboot_enable to "NO", preventing /boot/nextboot.conf processing on next boot. bootonce and nextboot features are usable in both UEFI and BIOS boot. To use bootonce/nextboot features, the boot loader needs to be updated on disk; if loader.efi is stored on ESP, then ESP needs to be updated and for BIOS boot, stage2 (zfsboot or gptzfsboot) needs to be updated (gpart or other tools).
