tim at home work and in between.

At Home.

Nothing much to report, my eldest asked for a chemical brothers CD for his birthday - pretty cool Huh!

At Work.

Spent half the day trying to decode what a customer's problem really was. We had several iterations of decoding techno babble until a clear problem statement emerged. With that we have a plan to work to a solution so lets wait and see what happens.

Connected the webcam to a sunblade 2000 in our lab, pulled down the usbskel driver from http://docs.sun.com/app/docs/doc/816-4854/6mb1o3ah2?q=usbskel&a=view the only thing missing is a Makefile. Here is what I used..

all: usbskel

usbskel: usbskel.c usbskel.h

        cc -D_KERNEL -xarch=v9 -c usbskel.c

        ld -dy -r -o usbskel usbskel.o -N misc/usba

Not the most elegant but enough to get a driver to put in /kernel/drv/sparcv9 together with this in /kernel/drv/usbskel.conf

usbskel_dumptree=1;

usbskel_parse_level=1;

and when I add_drv the usbskel driver to own interface 0 of the device thus..

add_drv -m '* 0666 bin bin' -i  'usbif46d,8f0.100.config1.0' usbskel

I get this in /var/adm/messages...

I just need to work out what that means...

In Between.

15 miles in the bus ( ford galaxy - one of the best buys I have ever made).

0 miles on the bike, but I will ride it tomorrow as the bus gets serviced.

200 pounds on a set of front tyres for the bus, mind you they have done 35000 miles.
