I already had this on 12.2.
What's new to me is the line before:
WARNING: Device "fb" is Giant locked and may be deleted before FreeBSD 14.0.I already had this on 12.2.

screen.font="8x16" will reduce the font size and make it appear the same size as VT 1024x768 font size from FreeBSD 12.2.Although both of these options are still documented in vt(4) for FreeBSD 13, they are indeed not working anymore. A message on the freebsd-current mailing list from january suggests that there are now loader tunables to set fore-/background colors, but no mention of those in loader.conf(5).
(vt_)efifb is a framebuffer device driver that accesses the graphics hardware through UEFI's graphics output protocol (GOP) without needing a specialized graphics device driver. Once a KMS driver is loaded (like one provided by graphics/drm-kmod) it replaces efifb.
This explains it. Hopefully the loader tunable options will show up somewhere.
teken.fg_color="7"
teken.bg_color="4" grep -E "teken\.[fb]g_color" /usr/src/sys/kern/subr_terminal.c TUNABLE_INT_FETCH("teken.fg_color", &fg);
TUNABLE_INT_FETCH("teken.bg_color", &bg);
I've noticed a performance boost of about 3-5%, but the most interesting thing about FreeBSD 13.0 is the loader tunable options.grep -E "teken\.[fb]g_color" /usr/src/sys/kern/subr_terminal.c
There! Feel free to experiment.Code:TUNABLE_INT_FETCH("teken.fg_color", &fg); TUNABLE_INT_FETCH("teken.bg_color", &bg);
I am still working through my 12.2 -> 13.0 update queue but once I'm through I sure will have a closer look at those.
On a sidenote: Thanks to vt_vbefb I now got a high(er) resolution console with loadable fonts and fast vt switching using a 1996 graphics card *yay*
The colors are defined in /usr/src/sys/teken/teken.h and seem to correspond to standard ANSI colors:
typedef unsigned char teken_color_t;
#define TC_BLACK 0
#define TC_RED 1
#define TC_GREEN 2
#define TC_BROWN 3
#define TC_BLUE 4
#define TC_MAGENTA 5
#define TC_CYAN 6
#define TC_WHITE 7
#define TC_NCOLORS 8
#define TC_LIGHT 8 /* ORed with the others. */ fg = bg = -1;
TUNABLE_INT_FETCH("teken.fg_color", &fg);
TUNABLE_INT_FETCH("teken.bg_color", &bg);
if (fg != -1) {
default_message.ta_fgcolor = fg;
kernel_message.ta_fgcolor = fg;
}
if (bg != -1) {
default_message.ta_bgcolor = bg;
kernel_message.ta_bgcolor = bg;
}
if (default_message.ta_bgcolor == TC_WHITE) {
default_message.ta_bgcolor |= TC_LIGHT;
kernel_message.ta_bgcolor |= TC_LIGHT;
}
if (default_message.ta_bgcolor == TC_BLACK &&
default_message.ta_fgcolor < TC_NCOLORS)
kernel_message.ta_fgcolor |= TC_LIGHT;
teken_set_defattr(&tm->tm_emulator, &default_message);options TERMINAL_NORM_ATTR=(FG_LIGHTGREY|BG_BLACK)
options TERMINAL_KERN_ATTR=(FG_LIGHTBLUE|BG_BLACK)The TERMINAL_(NORM|KERN)_ATTR options worked just the same way in vt(4) as the corresponding SC_KERNEL_CONS_ATTR and SC_NORM_ATTR options in sc(4) did before. They got active as soon as the kernel started booting, but not before that (i.e. in loader). The KMS driver should not have any effect on that and is also loaded much later in the boot process. Some tunable options like kern.vt.fb.default_mode however do only work if a KMS driver is present. Not sure when exactly vt(4) became the default console, but it was the default in 12.2 already and has been around since FreeBSD 9.3:
HISTORY
The vt driver first appeared in FreeBSD 9.3.That's when the KMS driver replaces vt_vga/vt_efifb and optionally switches to a higher resolution mode.
Well, looks like someone thought it would be a good idea to have consistent colors during the transition from loader to kernel. YMMV. I generally dislike such restrictions being imposed on me.
teken.fg_color="4"
teken.bg_color="0"
screen.font="8x16"
teken.fg_color="7"
teken.bg_color="4"

exec shouldn't be necessary, giving the mode to efi_max_resolution should work just as well.Actually, I read that laptops are going with a taller and less wide ratio nowadays so you might look into that.
What screen font sizes are available?
Check /boot/fonts
