loader: Move to using linker sets to bring in optional bits2024-04-16T19:54:24ZWarner Loshimp@FreeBSD.org2024-02-16T03:53:47Zurn:sha1:94e1374b55c7c3ac484bbe0631591545a5536c8d
The graphics stuff is optional. When it is pulled into the system, we
use a linker set to initialize the lua bindings for it now.

Create a new gfx global table. Put into it all the graphics bindings
that we have in loader today. For now, have compatability binding for
loader. Remove them from loader.

loader: Fetch initial script from loader_lua env2024-04-16T19:54:23ZWarner Loshimp@FreeBSD.org2024-02-14T17:51:38Zurn:sha1:8ea26f3280f7df1aad1c34d5bad1472a02c18fdf
Sometimes it is nice to override the initial script that we run. Make it
possible by fetching loader_lua from the env and using that instead of
the default if prsent.

loader: Use tslog to instrument some functions2021-06-21T03:09:48ZColin Percivalcperciva@FreeBSD.org2021-05-31T00:01:25Zurn:sha1:313724bab940c1844fda3d797cf88cd46780e62a
In my initial testing, these are the functions which showed up as
being worth instrumenting. More may be added later.
common/console.c: cons_probe
common/gfx_fb.c: read_list, insert_font, autoload_font
common/interp.c: interact
common/interp_lua.c: interp_init, interp_run
efi/libefi/efipart.c: efipart_readwrite
i386/libi386/biosdisk.c: bd_init, bd_open, bd_edd_io, bd_chs_io, bd_io
libsa/open.c: open
libsa/read.c: read
libsa/twiddle.c: twiddle
Note that profiling interp_run may be of questionable utility as it
may depend on user behaviour (e.g. pressing keys).

stand: liblua: add a pager module2020-12-12T21:25:38ZKyle Evanskevans@FreeBSD.org2020-12-12T21:25:38Zurn:sha1:0a0d522b368b31ec51611b798047a75b52855f39
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.

lualoader: drop the filename and word "LUA" from errors2020-06-03T18:29:32ZKyle Evanskevans@FreeBSD.org2020-06-03T18:29:32Zurn:sha1:48260b4b5320a68fd13f9f9dd52e85dc4b750ebb
The filename is nearly always wrong since it's /boot/lua/loader.lua, which
is not useful for diagnostics. The actual errmsg will include a lua filename
if this is relevant.
Dropping "LUA" while we're here because that's almost universally
irrelevant to whatever error follows, unless the error states that it's
actually a lua problem.
Both of these are minor nits that just detract from identifying the
pertinent information.

interp_lua: fix bogus indentation, NFC2020-02-12T16:10:00ZKyle Evanskevans@FreeBSD.org2020-02-12T16:10:00Zurn:sha1:8e173ae7f494838227893430bda0c5c4ec8a312clualoader: disable autoboot on high-level interpreter errors2020-02-12T16:09:01ZKyle Evanskevans@FreeBSD.org2020-02-12T16:09:01Zurn:sha1:17f0dc77a4e511cd5b35e50bccf71e236c78c574
If we hit an error at this level, we are almost certainly not in any kind
of sane state where autoboot can do the right thing. Instead of letting it
try and probably failing, disable autoboot so they immediately get kicked
into a loader prompt for manual remediation/diagnosis.
