* stand: Ugly hack due to default changeWarner Losh36 hours2-2/+2
| | | | | | | | | | | So this is a gross hack to fix the 'noclean' build since we changed to text-only loader. We have to fix it in a better way, but for the moment, this will fix non-meta no-clean builds. A better hack is to fix this so we build either vidconsole.c or textvidc.c, but some minor refactoring and variable renaming is needed. Fixes: 23dee252daf2 Sponsored by: Netflix
* loader: Change this BIOS tradeoff: Add back zip and use text onlyWarner Losh5 days1-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | After talking with a number of people about the removal of some things to make the loader fit, readjust things a little. Add back GZIP and BZIP2 compression support. Many of the downstream MFC packaging systems depend on this. This adds back 20k to the size of the loader. Make the boot loader text-only by default. This saves 40k in size. Net, we're 20k smaller. The graphics loader for BIOS is less useful than the zip functionality: You can still boot w/a text only one it and you can build a custom one if you really want it. It's also the default we use for dual console. This should be merged back into stable/14 and stable/13 so it's in the next release for each of these. That way we have only one release (13.4) with the other defaults. MFC After: 3 days Sponsored by: Netflix Reviewed by: olce, rgrimes, emaste Differential Revision: https://reviews.freebsd.org/D47203

* pxeboot: Enforce a 500k limit hereWarner Losh2024-08-061-0/+8
| | | | | | | | | | | | | | Have a separate PXEBOOTSIZE variable that acts much like LOADERSIZE variable to limit the size of the loader used for pxeldr. This allows people to override it independently of LOADERSIZE, which they may need to set larger for other reasons. Combined with PXEBOOT_DEFAULT_INTERP, you can build a larger lua loader, while still being able to build pxeldr with the 4th one, for example.

When /boot/loader needs to be larger like that, this options will disable a component whose build will fail. It is an explicit option rather than implicit when things are too large to force the user to make the explicit tradeoffs rather than wonder why they have a stale pxeboot or other odd failure mode.

* stand: Reduce limit to 500k for x86 loaderWarner Losh2024-08-011-1/+6
| | | | | | | | | | | | | | | | | The largest loader that works for PXE boot is about 500k. PXE needs low memory for packets and other driver state, so the largest safe size for the loader is about 500k. Reduce the size from 560k to 500k so we don't accidentally break PXE in the future. Add a comment for people with special needs. If you control the hardware, it can be safe to have boot loaders as large as 580k or 600k in some cases. Since the BIOS loader is becoming more and more of a legacy item, the build variable LOADERSIZE isn't documented. This change doesn't change that: there's been little demand for this documentation and in general, users shouldn't change it lightly. PR: 257018 Sponsored by: Netflix

Anything older than 3.0 will be given a warning that their boot loader is too old.

| | | | | | | | | | | | | | | | | | | Select between text-only and graphical frame buffer consoles for the BIOS boot loader. Pull one or the other in with #ifdef in conf.c. Add gfx_bios.c for the few routines that are needed for the BIOS support of gfx. These are stubbed out for text-only mode. Move bi_load_vbe_data here since it's only used for the graphical frame buffer. Note: This setup also allows us to build multiple BIOS loaders if we have to, some with text-only and some graphical. We don't do this today. We may be forced to turn this on in the future if ZFS keeps growing. The size savings is 41k, which helps a lot with some of our users that want to enable more options in the BIOS boot loader than are normally safe to do, and they don't need graphics.

This console does no graphics stuff at all, supports no fancy logos, has known bugs in the terminal emulation, etc. However, it is small. It will be a build-time option to select between the two. The BIOS loader is running out of space when too many options are selected, so this allows people to select the smaller one to spend the space elsewhere.

* loader: lua: assume late ACPI detection if the feature isn't enabledKyle Evans2023-12-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | While we're here, enable the feature in the places we detect ACPI. This lets us side-step the existing issues and provide a path forward for folks upgrading from previous releases that haven't updated their ESP yet. Let's also fix core.setACPI: the hint already indicates that the user's disabled it more consistently than loader.acpi_disabled_by_user. Even more, the latter is wrong because we set it by default if we did not detect ACPI. The ACPI hint remains even when we're setting defaults because ACPI loaded into the kernel will make some noise if it's not hinted off, even when we didn't detect it. imp notes that this will result in some relatively harmless noise on platforms that don't support ACPI but aren't using the UEFI loader, as we would enable the ACPI module for loading on them and then loader would not be able to find it. These are non-fatal, but should probably be fixed by just declaring support for EARLY_ACPI in those loaders since we know they won't have ACPI early on -- punting on this for the time being, though, in favor of providing a safer upgrade path sooner.

| | | | | | | | | | | | It would be nice to have larger boot partitions for ESPs to live in one day. It's trivial to carve out 5M 10M or 200M when provisioning, but logistical issues may make it hard to do it after the fact. So only warn when the partition is > 545k. If we ever grow the boot loader larger than that, then it will be responsible for loading the rest anyway.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the 'renaming kludge' that we absolutely cannot do going forward (it's cost us days of engineering time). console=comconsole talks to the hardware directly. This is available only on amd64. It is not available anywhere else (and so requires changes for people doing comconsole on aarch64) console=eficom talks to the console via EFI protocols. It's available on amd64, aarch64 and riscv64. It's the first port that we find, though it can be overriden by efi_com_port (which should be set to the UID of the serial port, not the I/O port, despite the name). devinfo -v will give the UID to uartX mapping. This is an incompatible change for HYPER-V on amd64. It only works with eficom console, so you'll need to change your configuration in loader.conf. No compatibility hack will ever be provided for this (since it requires renamig, which the loader cannot reliably do). It's also an incompatible change for aarch64. comconsole will need to change to eficom. There might be a comconsole "shim" for this. All the interlock to keep only eficom and comconsole from both attaching have been removed.
