Re: entire cache is busy, 999 dirty

Hello erik,

probably not.
I will refresh my file server.

Thanks

To all of you who put the FTDI usb/serial driver in place, I thank you.  I'll be exercising it significantly
over the next week or so.

Re: venti problem

Thanks for the links, now everything is working (apparently), but I
have no idea what was the source of my error(s).

Retargeting 8{al}?

Hi,

I am working on a 32-bit microprocessor-on-an-FPGA; anyone know
what'd be involved in retargeting 8{al} (or friends) to a new 
CPU? Where is the line between what 8a and 8l do? (which is
responsible for the pseudoregisters? instruction selection?)

Thanks,

building the 9phone

For all of you who have not seen this:
http://www.sparkfun.com/commerce/product_info.php?products_id=7917

The manual is here:
http://www.gm862.com/en/products/gsm-gprs.php?p_id=12&p_ac=show&p=7

You can build up a little phone with a gumstix and one of these. You
can script with Python. Or you can use a beagleboard, and you have the
option of plugging your phone into display/keyboard when you are home.
It's the anti-iPhone, you own the whole thing, you can do what you
want. Headphone/mic would not go via Plan 9, it is a direct connect.
These really are little cell phones in a module.

I worked with these several years ago at LANL. It was not so easy back
then as the SIM support was not great in the US. I never got PPP
working on it as you were supposed to be able to do.

You have to be careful, too: I fried one, guess it was static
sensitive? But note that they're even selling modules for use as
controllers for your
house!http://www.sparkfun.com/commerce/product_info.php?products_id=8700

Just an interesting project for someone. I think it would be easier
now, I even see SIMs for sale in airports.

Can't compile kernel

Hello!

In parallel to the old Laptops i have installed Plan9 now on an ACP 
mini motherboard.  Did not work out, until i found the Eric Qanstroms 
9atom.iso - a Big thank you to Erik.

Why would it be that this ISO not mentioned in the installation 
instructions on the Plan9 wiki...?

Next step would have been, to compile a pccpuf kernel.  Easy enough:
  cd /sys/src/9/pc
  mk 'CONF=pccpuf'

But! instead of a kernel i get:
  ../port/flags: '../port/flags' does not exist
  ../boot/libboot.a8 doesn't exist: assuming it will be an archive
  8c -FTVw i8253.c
  mk: no recipe to make 'devcec.8' in directory sys/src/9/pc

A 'pull' updates some files, but does not change the situation.

Any tip to get me working?

Regards,

	Jorge-León

it's because i've screwed something up.  big apoligies to everyone
who's found this problem.  here are two work arounds until i get
this fixed:

a) remount the 9atom.iso iso.  copy -x the kernel files onto your
/sys/src/9/*

b) downloead ftp://ftp.quanstro.net/other/kernel.mkfs.bz2
unpack into /sys/src/9

evidently i need to modify the replica configuration files to
get this file to copy over.  the point of this extra file is to
support the linker tricks needed to get ron's excellent tracing.

again, i'm really sorry about this.  i will fix soon and put out
a new image.

contrib/gui

after talking about it for some time
I got tired of talking and wrote a simple
gui installer for contrib
so if you pull contrib, you'll get a contrib/gui

here's a shot:

ah, the code is not the best, but
it gets the job done
