- We should be setting a known graphics mode on conout, but we aren't.
- We shouldn't be setting gop mode if we didn't find a good resolution to
set, but we were. This made efi_max_resolution=1x1 effectively worthless,
since it would always set gop mode 0 if nothing else.
Harry Schmalzbauer reports that some firmware, in his experience, trips
over the ESP we install due to the volume label. It has been theorized that
this is due to some confusion with the label and the path on the ESP to
boot1.efi.
Regardless, Harry found that renaming the label seems to fix it.

With r328289 we attempt to make sure we free the resources allocated in
help_getnext(), however, it is possible that we get no resources allocated
and help_getnext() will return early.
Make sure we have pointers set to NULL early in help_getnext().

While Arcnet has some continued deployment in industrial controls, the
lack of drivers for any of the PCI, USB, or PCIe NICs on the market
suggests such users aren't running FreeBSD.
Evidence in the PR database suggests that the cm(4) driver (our sole
Arcnet NIC) was broken in 5.0 and has not worked since.

Refactor the currdev setting to find the device we booted from. Limit
searching when we don't already have a reasonable currdev from that to
the same device only. Search a little harder for ZFS volumes as that's
needed for loader.efi to live on an ESP.

Earlier efforts to stop loading the menu broke the ability to skip the menu
with, e.g., beastie_disable in loader.conf(5) as it was decided before
configuration was read.
Defer bringing in the menu module until we've loaded configuration so that
we can make a more informed decision on whether the menu should be skipped
or not.
btxld does not correctly handle input with other than 2 PT_LOAD

When booted via isoboot(8) loader will be handed a disk that simply contains
an ISO9660 image. Currently this confuses it greatly. Teach it how to spot
that it's in this situation and that ISO9660 has one "partition" covering

This is part of a project for adding the ability to create hybrid CD/USB boot
images. In the BIOS case when booting from something that isn't a CD we need
some extra boot code to actually find our next stage (loader) within an
ISO9660 filesystem. This code will reside in a GPT partition (similar to
gptboot(8) from which it is derived) and looks for /boot/loader in an
ISO9660 filesystem on the image.

Effectively disabling the mode changing bits in the loader. No matter which
way we go with it, it seems to be wrong- either the firmware doesn't change
the resolution and reports the resolution we requested, or the firmware
changes the resolution and doesn't report the resolution we requested. It
some cases, it does the right thing, but the bad cases outweight those.
Interested individuals can still set efi_max_resolution to 1080p or whatnot
in loader.conf(5) to restore the new behavior, but the new behavior does not
work out well for many cases.

This commit splits all of the logodefs/graphics out into their own own files
and provides a method for these files to register their logodefs with the
drawer. Graphics are now loaded on demand if they don't exist in the current
set of logodefs.
The drawer module becomes a little easier to navigate through without all of
the graphics mixed in. It's also easy to do one-off graphics like the
9.2 Die Hard tribute by dteske@ without adding even more to our memory
requirements.
- No need for a 'goto' when our entire loop body is then wrapped in a
conditional.
- No need to leave commented out prints laying around
- If an expression is clearly going to be either nil or an expression that
isn't likely to be a boolean, we might as well use `or` to specify a
default value for the expression. e.g. `loader.getenv(...) or "no"`
The previous iteration of this assumed that {module}_load was set. In the
old world order of default loader.conf(5), this was probably a safe
assumption given that we had almost every module explicitly not-loaded in
it.
In the new world order, this is no longer the case, so one could delete a
_load line inadvertently while leaving a _name, _type, _flags, _before,
_after, or _error. This would have caused a confusing Lua error and borked
module loading.
If the network interface or the uefi implementation do not support the
ReceiveFilter interface do not return only and just print a message.
U-Boot doesn't support is and likely never will. Also even if this fails
it doesn't mean that network in EFI isn't supported.
hrs@ and kuriyama@ have found that on some HP BIOS, a system will fail to
boot immediately after installation with the claim that it can't work out
which disk they are booting from.
They tracked it down to a buffer overrun, and found that it could be
alleviated by doing a dummy read before-hand.

It was previously only printed, but we do actually want to raise it as a
full blown error so that things don't look OK when they've actually gone
wrong.
The second parameter to error, level, is set to 2 here so that the error
message reflects the position of the try_include caller, rather than the
try_include itself. Example:
LUA ERROR: /boot/lua/loader.lua:46: /boot/lua/local.lua:1: attempt to call a
nil value (global 'cxcint').
This provides a way to optionally include a module without having to wrap it
in filesystem checks. try_include is a little more robust, using the lua
search path instead of forcing us to explicitly consider all of the places
we could want to include a module. Errors are still generally raised from
trying to load the module, but ENOENT will not get raised unless we're doing
a verbose load.
This will also be used to split out logo/brand graphics into their own files
so that we can safely scale up the number of graphics included without
worrying about the extra memory consumption- opting to lazily load graphics
instead.

UGA does not have the same kind of mode enumeration that GOP does. Implement
it instead as a call to text_autoresize so that firmwares with only UGA
present still get some kind of autoresizing behavior.
While here, rename a typo'd "gop" to "uga", although it will remain unused
for the time being.
This pertains exclusively to the set/restore functionality that we offer,
where any changes made by loader.conf previously will be effectively removed
upon reload of the configuration. We don't currently have a need to export
these, so don't bother.
Not all systems use efifb; pull hw.vga.textmode and choose a good console
mode instead if it's set to something non-zero. This is basically a revival
of the code that used to live in boot1, but instead rebased onto this
different way of doing mode selection in loader.efi.
Interestingly enough, the regression that was previously introduced where
GOP would not reflect the console setting does not seem to exist when
console mode selection is done here. I've not done any investigation as to
why this is the case. Nevertheless, boot1.efi is still not the best place to
do mode selection.
Default the max resolution to 1080p, we'll accept Width x Height
specifications along with the following presets:
- 480p
- 720p
- 1080p
- 2160p or 4k
- 5k

I thought I tested this scenario, but clearly I failed to. =(
BIOS boots won't have efi-autoresizecons, so trying to use it as a forth
word fails during include. Use evaluate on "efi-autoresizecons" as a string
instead to move any potential errors to runtime- safely after we've already
checked that we're booting UEFI.
Pointy hat to: me
Reported by: cy
r331321 delegated autoresizing to an efi-autoresizecons command that
currently is expected to be done in forth/lua prior to drawing anything
useful.
Add the Forth version of the lua addition in r331321, hook efi.4th up to be
installed.
efiboot? was written by dteske@; anything outside of that may be blamed on
me.
boot1 is too early to be deciding a good resolution. Console modes don't map
cleanly/predictably to actual screen resolutions, and GOP does not reflect
the actual screen resolution after a console mode change. Rip it out.
Add an efi-autoresizecons command to loader to choose an optimal screen
resolution based on the current environment. We'll explicitly execute this
later, preferably before we draw anything of value but after we load config
and pick up any tunables we may need to decide where we're going.
This method also allows us to actually pass the correct framebuffer
information on to the kernel.
UGA autoresizing is not implemented because it doesn't have the kind of mode
enumeration that GOP does. If an interested person with relevant hardware
could get in contact, we can take a look at implementing UGA autoresize.
This effectively "fixes" the breakage caused by r327058, but doesn't
actually set the resolution correctly until the interpreter calls
efi-autoresizcons. The lualoader version of this has been included for
reference; the forth equivalent will follow.
