(Nearly) full tickless operation in 3.10
A line in the sand for graphics drivers

Like the intel driver supports i855? modulo the bugs that made it completely lock up at random moments in recent versions of the driver (2.10 version appears stable, wont try anything newer now that I have a working setup again).
Then again, I have no ATI display adapter use experience. So it just might be the only video driver that never hangs, shows corrupted textures, has problems resuming from suspend, etc when used with too old or new hardware variants...
The too old/too new issue is also with driver versions.
1. Report a bug on driver X.
2. "Thats too old, it might be fixed in the git head"
3. compile, try, hit another issue
4. "you are running it on too old kernel, upgrade to latest kernel from the drm tree"
5. compile, try, hit some other bugs
6. "you are running the developer versions of kernel and graphics driver, of course there are some bugs."
I'm not criticizing the driver developers. There is just too few dedicated and active X driver developers compared to the amount of hardware variants that needs supporting and the complexity of graphics driver development...

I have an 855-based laptop as well, and the lockups are very frustrating. But it isn't a matter of "driver bugs" so much as "failure to find a good workaround for hardware bugs".

No, no such chip-wide breakage in the ati land. I've r200 working fine, and r100 is reportedly also pretty ok (for the class of hardware it is) under KMS. I've also r700 with the ati driver without a hitch and more stable (that is = stable) than the proprietary driver.

I must just be unlucky, then. It seems all of my ATI cards are among those with bugs (which yes, have all been reported). I have still yet to find an ATI card with working KMS :-(

(I've got a 4870, FWIW.)
