termrc and aux/realemu

[kokamoto]

Please rewrite the /rc/bin/termrc to load aux/realemu, 
enen if we have
monitor=vesa
vgasize=...x...x..
lines in the plan9.ini file.

kenji,

termrc does call aux/realemu at line 107.

		@{
			rfork n
			if(~ $monitor vesa)
				aux/realemu
			aux/vga -l $vgasize
		}

what is the problem with it?

I don't like shell script, so this is from my experience.

 termrc does call aux/realemu at line 107.

This is called only when vga and vgasize are set to be
asked?
I had to write aux/realemu line expricitly in
/cfg/xxx/termrc file.

Have you tested it when you have
monitor=vesa
vgasize=...x...x..?

in my thinkpad X301 plan9.ini is:

monitor=vesa
vgasize=1440x900x32

it works. when i tcpboot to my fileserver, rio starts automatically.

working as intended :-)

do you get any messages on the console when aux/realemu doesn't run?

I think we may be misunderstanding what your situation is. The language
is too ambiguous. Can you please:

1.) describe what you did
2.) describe what you expected to happen
3.) describe what actually happened

Thanks!

Ok.
my /rc/bin/termrc is the same as distribution.
My termrc.local has only one line of
TIMESYNCARGS=(-n ntp.jst.mfeed.ad.jp)

/cfg/pxe/xxxxx file is as follows:
#saturn C2D machine
bootfile=/386/9pcf
bootargs=tcp
fs=192.168.11.5
auth=192.168.11.5
mouseport=ps2intellimouse
monitor=vesa
#monitor=s2231wA
#vgasize=1024x768x16
vgasize=1400x1050x16
#vgasize=1680x1050x32
#vgasize=1600x1200x32

and /cfg/saturn/termrc has a line of
#!/bin/rc
aux/realemu

and /cfg/saturn/termrc has a line of
#!/bin/rc
aux/realemu

If I don't have the last file, it bootup with no problem.
However there is no /dev/realmode file.
To have this file I have to have the last file.

Is this Ok?

Re: [9front] termrc and aux/realemu

kenji, why do you need /dev/realmode file? the file is only used
when setting up graphics with the vesa driver which is done in
termrc. the reason you do not see the file is because termrc
*intentionally* forks the namespace and runs aux/realemu
and aux/vga in that namespace. so we wont clutter /dev
with slow userspace fileservers. it also doesnt start
realemu when you'r not using vesa. this is all intentional.

why do you need /dev/realmode file? why do you not just
set monitor=vesa and vgasize= variable to set graphics mode?
do you wish to set up graphics later in your own scripts?
in that case, you can just run aux/realemu yourself there
before running aux/vga. what are you trying todo?

Ok, I got you intentionaly did so. Then,
I don't undestand why /dev/realmode makes the system slow.

Why we need to separate this.
You don't want user mode device should not appear in /dev?
We couldn't have /dev/realmode anytime?

If it's not good, we should make aux/vga do it automatically.
I'm wrong?
