[timer] Formalise the timer API

2008-10-12T19:22:02+00:00

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().

[Timers] Initialise timers on first use

2008-03-18T15:23:10+00:00

Timers are sometimes required before the call to initialise(), so we cannot rely on initialise() to set up the timers before use. Also fix a potential integer overflow issue in generic_currticks_udelay()

[Timers] Miscellaneous timer system fixes

2008-03-18T14:48:28+00:00

Add missing comments to timer code. Lock system if no suitable timer source is found. Fix initialisation order so that timers are initialised before code that needs to use them.

Cleanups

2008-03-02T01:36:50+00:00

Replace a printf with a DBG in timer_rtdsc.c Replace a printf in timer.c with assert Return proper error codes from timer drivers Signed-off-by: Alexey Zaytsev

Introduce the new timer subsystem.

2008-03-02T00:15:07+00:00

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

Dead code removal.

2007-07-14T14:42:26+00:00

Kill off use of etherboot.h outside drivers/net.

Kill off poll_interruptions(); it is lethal when we're acting as a PXE

stack or INT 13 emulator etc.
