#*sigh* And this would also mean that my joystick driver will fallback into
#PIT timing mode on a Cyrix, though it could safely use the TSC timer, since
#there isn't a chance of the CPU getting a HLT instruction while it is timing
#the joystick input ...
Thank you SO much Vojtech. I've been trying to remember something that
REALLY relies on the TSC to support my suggestion all day. Now I can reply
to Linus' mail! Yay! }:)
#If I could suggest a solution, add a bug flag for this behaviour, and check
#for presence of TSC and absence of the bug in do_fast_gettimeofday. The TSC
#simply is there, though not suitable for all uses.
Perhaps, perhaps not. There IS a way to address it correctly in ALL
situations, I just don't remember it.
#Also, it'd be neat if the kernel had some public variable containing the
#real TSC increment speed for each CPU, say in ticks per second or
#microsecond, so that drivers using the TSC wouldn't need to calibrate it.
Oooo, that WOULD be *VERY* handy. Instant-sync. I like. :)
