Vojtech Pavlik b2df3ddb68 [PATCH] x86_64: Explain why HPET T0_CMP register is written twice ... After writing the CFG register, the first value written to the T0_CMP register is the value at which next interrupt should be triggered, every value after that sets the period of the interrupt. For that reason, the code needs to write the value twice - to set both the phase and period. [AK: I had already figured it out by myself, but it's still useful to have a comment for this.] Signed-off-by: Vojtech Pavlik <vojtech@suse.cz> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>		2006-06-26 10:48:19 -07:00
