[9fans] Trap in 5c compiling rc?

[9fans] Trap in 5c compiling rc?

[Paul Lalonde]

[-- Attachment #1: Type: text/plain, Size: 400 bytes --]

I'm trying to build an arm userspace, and I'm dying building rc; 5c is dying
at /sys/src/cmd/5c/peep.c:1338, with joinsplit() having been called with
r=0x0.

I'm running from an old distro, but with today's sysfromiso by ron.

Any (non-null) pointers?

Paul

hmmm works on all 5cs i have. charles will fix the glitch, maybe.

5c is interesting in that there are more arms than on capitol hill. i
have a little plan...

it seems to work with the ones i've got.
i'll see how those compare with sources.

i can't get 5c to fail when compiling rc. ghostscript might be another matter;
i haven't tried that yet.

Re: [9fans] Trap in 5c compiling rc?

that's what i wouldn't attempt.

at least on my openrd, everything in /sys/src/cmd
compiles with no problems, including gs.

I've rebuilt my x86 userspace, nuked, rebuilt objtype=arm, and still in rc,
bang.
I'm running on 9vx, so I can imagine some random interaction there (I can't
justify the power bills to keep a plan9 386 box going these days given the
frequency I use it).
An rc would let me move all this over to my plug and worry less, methinks.

Erik sorted me out - and our wee conversation made me remember that in the
presence of 'bind -b /sysfromiso /' it's important not to get the arguments
backwards.
Mea maxima culpa, apologies for the noise.

now that paul has things fixed, perhaps this is of no value, but since it's
already done, i'll put it out there.

i've generated two tarballs, one for 16-bit runes, and one for 32-bit runes
containing /arm with libraries executables.

	hget ftp://ftp.quanstro.net/other/slasharm16.tbz | bunzip | @{cd / ; tar x arm/bin}
	# sha1sum
	# cb057e9335c99b5f75f715358735653a8b1fe17c	slasharm16.tbz

or for 32-bit runes (use this if you're using 9atom)
	hget ftp://ftp.quanstro.net/other/slasharm32.tbz | bunzip | @{cd / ; tar x arm/bin}
	# sha1sum

the atom boards are not too bad.

Re: [9fans] Trap in 5c compiling rc?

[ron minnich]

just a reminder, when I build from sysfromiso, on 9vx:

cd sysfromiso
hg pull
hg up
bind sys/src /sys/src
bind sys/include /sys/include
cd /sys/src
objtype=arm
mk nuke
mk install

I've used this to build bootable openrd kernels. I'm rerunning it now.
It always takes time because of gs, but gs is a great test. I'll
update with a note on how it went.


I just did a push from sources to the sysfromiso repo.

I got it clean, finally.  I had mis-mapped some pieces while updating my x86
userland, without which 5c crapped out a lot.

Next question: How do I build my plug kernel?  Among my early build
problems:
    mk: no recipe to make 'devtwsi.5' in directory /sys/src/9/kw
    ../boot/libboot.a5 doesn't exist: assuming it will be an archive
    mk: no recipe to make 'syscallfmt.5' in directory /sys/src/9/kw

I'm not finding current "how to build a kernel" bits anywhere :-(

I thought that stuff was already in sysfromiso -- done a pull lately?

you can just chop twsi out of your kernel configuration and build.
i'd be happy to put a pre-built arm kernel out, too.

Getting closer.  I still seem to be lacking syscallfmt.c which is called out
explicitly in the mkfile but isn't in sysfromiso.  The version in sys/pc
clearly won't work.

You can't just grab it off sources?

	9fs sources
	fcp /n/sources/plan9/sys/src/9/kw/syscallfmt.c /sys/src/9/kw/

I rebuilt 9plug on a fresh native plan 9n distribution in the last hour,
without a hitch.  I even tested it on my sheevaplug and other that I
haven't yet figured out how to get flash going, it worked without any
intervention.

Any suggestions on getting rid of the need for a console by supplying
#F/flash/flash0 and putting intelligent settings in there?  I'd love
to get to the point where the sheeva just starts up without human
intervention when there are file and auth services for it to use.

I'm a little concerned about guessing my way around flash, I'd rather
have instructions that are known to work.  But the sheer simplicity of
the whole system is mind boggling.

see /cfg/pxe/example-kw.  with careful selection of a flash address,
one can also put the nvram on #F.

there is no current version in pc.  this is what you're intersted in

Time for that consolidation of fsfs, disksim and other such disk tools
into one.  In your case, I think fsfs is what you need, but I'd hate
to be the one to figure it all out.

I have a successful boot off my USB stick onto the Guru.

Now, how do I tell it to use the USB stick as a root filesystem?  I'm
guessing I'll want to have two partitions, one to hold the image and another
as a native P4 fs of some sort (if only to get case-sensitive filenames).
 How do I specify the later to the "root is from" prompt?

I've gotten part of the way there. I set up a 9fat on the first
partition and I can boot the kernel from u-boot with the 9fat. But I'm
not quite done the rest.

The plug really needs fully hands-off booting and this does not seem to
be the direction you're heading.  I suppose my approach where the file
server is on the network isn't great either, although it may be suitable
for an auth server.

What are the various eventual uses for a plug running P9?  I can think of

	Stealth CPU server/AUTH server
	ARM development system (where's Go?)

Can't think of anything else, but I'm not great on the imagination thing.

I'm particularly fragmented now, but soon I'll want to focus on only a few
projects, so I'm offering to help any sort of concrete goals.  I have only
an oldish plug, probably a year old now, but it's dedicated to Plan 9.

Mind you, so is the YeeLoong and that doesn't seem to be going anywhere.

actually it is. My openrd (same as a plug) has a 500 GB USB hard drive
($50 from Frys; I was using a flash drive but ventifmt made it die)
and I'm working to a hands-off booting. I changed the boot environment
variables to default to booting from 9fat on the disk, and that gets
me to Plan 9. I don't understand why you think this is not hands-off?

Currently things don't work out so well when I boot :-)
But I have not touched it for a bit.

I don't want to have an outward-facing OSX or Linux. I trust Plan 9
more if only because I figure most people will ignore it ...

ARMs are great! Just look at the gumstix.

My application is home-control; I have an off-grid cabin that wants to run a
3G usb stick and a low-power cpu server to manage automation - pre-heating,
hot water, etc.  This lets me geek a little at the same time.

what do you mean by "image" here?
