works great on progressive, but I'm getting a green screen on xbmc (on progressive and black screen on interlaced). But it's maybe something wrong with my system - I haven't tried it on clean install.
(Also, there is a warning at xbmc.org by fritsch "Installation of the wsnipex repository which includes all relevant mesa patches in a stable version. Don't use oibaf ppa - it will produce black screens only.")
I think that wsnipex PPA only added this patch more than my PPA, so the warning could be ignored. No idea about the green screen, try asking to xbmc people.
I had to use gross hacks for LLVM, since its daily debian builds wouldn't work with a launchpad recipe (basically, I set up a script to automatically wget the latest successful build from the llvm jenkins, and import them into my ppa).
The problem is, libclc and mesa won't automatically recompile when LLVM is updated in my PPA. This is bad news, since they're both linked with the llvm runtime. Does anyone know how to set it up so that both of these will automatically recompile?
The primary purpose of this PPA is to provide the most up-to-date development snapshot of OpenCL support in the Mesa drivers. Bugs are being fixed and new cards are being supported every day in the LLVM and libCLC trunks, so this will give you a good idea of the state of open source OpenCL.
This requires you also have the oibaf PPA added to your sources as well, to install dependencies.
As always, the disclaimer is: this is an unstable development snapshot, so don't be surprised when things break.
