Occasional linux kernel driver hacking.
It's three weeks now I'm in France working at Sophia- Antipolis for Conexant. Things are starting to settle down and I hope I will restart coding for the emu10k1 project soon. For now I just try to keep up to date and follow the mailing list.
Not much work done today, but then again it's only 4 am ;-)
Movie of the Day
Lars von Trier "Dancer in the Dark" starring Bjork and Catherine Deneuve. A very strong movie in it's beauty and sadness. Not your every day musical. A definite must see, but be prepared to be moved.
Finally saw Emir Kusturica "UnderGround". Very good, better than "Black Cat, White Cat" I saw last week, which was already quite good.
As for the driver, implemented mmap() of the record buffer and done some bug fixing and cleanup. Also took the time to learn a bit more about linux memory management and memory maping.
I'm considering doing a rewrite of the sound driver just to see if I can reduce the amount of locking that is currently needed. The idea was inspired mainly by the sound drivers written by Jeff Garzik (which have little to no locking). This will probably remain as a private project until I can proof it is worth it (probably never). What I need to find is a way to measure the driver performance quantitatively.
I've have accepted the job in France (near Nice) and will start on the 13th November. I'll be working in Conexant Inc. developing linux drivers for their hardware. More details later.
Went to see an Apocalyptica concert. For those who don't know them they are a Finish group composed of four cello players, they are also a heavy metal band, doing covers of groups like Metallica, Sepultura and Slayer besides their original compositions. I'm not a big heavy metal fan but this concert was excellent. Have to get their latest album.

New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
