2008-10-12[timer] Formalise the timer APIMichael Brown1-4/+14
We now have two implementations for the timer API: one using the time-of-day counter at 40:70 and one using RDTSC. Both make use of timer2_udelay().
2008-03-02Introduce the new timer subsystem.Alexey Zaytsev1-1/+7
Timer subsystem initialization code in core/timer.c Split the BIOS and RTDSC timer drivers from i386_timer.c Split arch/i386/firmware/pcbios/bios.c into the RTSDC timer driver and arch/i386/core/nap.c Split the headers properly: include/unistd.h - delay functions to be used by the gPXE core and drivers. include/gpxe/timer.h - the fimer subsystem interface to be used by the timer drivers and currticks() to be used by the code gPXE subsystems. include/latch.h - removed include/timer.h - scheduled for removal. Some driver are using currticks, which is only for core subsystems. Signed-off-by: Alexey Zaytsev <alexey.zaytsev@gmail.com>
