Venki Pallipadi authored
Force detect and/or enable HPET on ICH chipsets. This patch just handles the detection part and following patches use this information. Adds a function to repeat the force enabling during resume time. Using HPET this way, instead of PIT increases the time CPUs can reside in C-state when system is totally idle. On my test system with Core 2 Duo, average C-state residency goes up from ~20mS to ~80mS. [ Build fixed from Andrew Morton ] Signed-off-by:

AMDs C1E enabled CPUs stop the local apic timer, when both cores are idle. This is a hardware feature which breaks highres/dynticks. Add the same quirk as we have for 32 bit already. Signed-off-by:
-
Thomas Gleixner authored
The clock events merge introduced a change to the nmi watchdog code to handle the not longer increasing local apic timer count in the broadcast mode. This is fine for UP, but on SMP it pampers over a stuck CPU which is not handling the broadcast interrupt due to the unconditional sum up of local apic timer count and irq0 count. To cover all cases we need to keep track on which CPU irq0 is handled. In theory this is CPU#0 due to the explicit disabling of irq balancing for irq0, but there are systems which ignore this on the hardware level. The per cpu irq0 accounting allows us to remove the irq0 to CPU0 binding as well. Add a per cpu counter for irq0 and evaluate this instead of the global irq0 count in the nmi watchdog code.

setup_APIC_timer disables interrupts anyway. So no need to do the same in setup_boot_APIC_clock and setup_secondary_APIC_clock. Disable interrupts explicit in the calibration code. Signed-off-by:

setup_APIC_timer takes the file global calibration result as an argument. Remove it. Signed-off-by:
-
Thomas Gleixner authored
APIC_DIVISOR is rather useless. It makes the calibration result more accurate in the first place, but we discard this later when we write the value to the APIC timer by dividing the calibration value by APIC_DIVISOR. Signed-off-by:

Thomas Gleixner authored
Let the calibration code fill in calibration_result directly and move the variable on top of the file. Fixup a printk w/o log level while at it. Signed-off-by:
-
Thomas Gleixner authored
The APIC timer setup code synchronizes the local APIC timer to the PIT/HPET. This is pointless as the PIT and the local APIC timer frequency are not correlated and the APIC timer calibration can never be accurate enough to avoid that the local APIC timer and the PIT/HPET drift apart. Simply remove it. Signed-off-by:

PIT clock events work already and the PIT handling is the same for i386 and x86_64. x86_64 does not support PIT as a clock source, so disable the PIT clocksource for x86_64. Use the i386 i8253.h include file for x86_64 as well to share the exports and the PIT constants. Signed-off-by:

Add the x8664 specific bits (mapping) to share the hpet code later. Move the reserve_platform_timer call to late init. This is necessary for x86_64, as hpet enable() is called before memory is setup. i386 calls it in late_time_init, but it does not hurt to do it later for both. Pull in the x8664 hpet disable command line option as well. Signed-off-by:

Thomas Gleixner authored
The hpet implementations of i386 and x8664 has been mostly the same before the clock events conversion of i386. The clock events conversion of i386 hpet is already done. So it makes sense to share the code for the x86_64 clock events conversion. Abstract out the mapping functions. Signed-off-by:
