SVN rev 224919 on 2011-08-16 21:51:29Z by mav Always check current HPET counter value after comparator programming to avoid lost timer interrupts. Previous optimization attempt doing it only for intervals less then 5000 ticks (~300us) reported to be unreliable by some people. Probably because of some heavy SMI code on their boards. Introduce additional safety interval of 128 counter ticks (~9us) between programmed comparator and counter values to cover different cases of delayed write found on some chipsets.

SVN rev 212541 on 2010-09-13 07:25:35Z by mav Refactor timer management code with priority to one-shot operation mode. The main goal of this is to generate timer interrupts only when there is some work to do. When CPU is busy interrupts are generating at full rate of hz + stathz to fullfill scheduler and timekeeping requirements. But when CPU is idle, only minimum set of interrupts (down to 8 interrupts per second per CPU now), needed to handle scheduled callouts is executed. This allows significantly increase idle CPU sleep time, increasing effect of static power-saving technologies. Also it should reduce host CPU load on virtualized systems, when guest system is idle. There is set of tunables, also available as writable sysctls, allowing to control wanted event timer subsystem behavior: kern.eventtimer.timer - allows to choose event timer hardware to use. On x86 there is up to 4 different kinds of timers. Depending on whether chosen timer is per-CPU, behavior of other options slightly differs. kern.eventtimer.periodic - allows to choose periodic and one-shot operation mode. In periodic mode, current timer hardware taken as the only source of time for time events. This mode is quite alike to previous kernel behavior. One-shot mode instead uses currently selected time counter hardware to schedule all needed events one by one and program timer to generate interrupt exactly in specified time. Default value depends of chosen timer capabilities, but one-shot mode is preferred, until other is forced by user or hardware. kern.eventtimer.singlemul - in periodic mode specifies how much times higher timer frequency should be, to not strictly alias hardclock() and statclock() events. Default values are 2 and 4, but could be reduced to 1 if extra interrupts are unwanted. kern.eventtimer.idletick - makes each CPU to receive every timer interrupt independently of whether they busy or not. By default this options is disabled. If chosen timer is per-CPU and runs in periodic mode, this option has no effect - all interrupts are generating. As soon as this patch modifies cpu_idle() on some platforms, I have also refactored one on x86. Now it makes use of MONITOR/MWAIT instrunctions (if supported) under high sleep/wakeup rate, as fast alternative to other methods. It allows SMP scheduler to wake up sleeping CPUs much faster without using IPI, significantly increasing performance on some highly task-switching loads.

SVN rev 212238 on 2010-09-05 19:24:32Z by mav Several improvements to HPET driver: - Add special check for case when time expires before being programmed. This fixes interrupt loss and respectively timer death on attempt to program very short interval. Increase minimal supported period to more realistic value. - Add support for hint.hpet.X.allowed_irqs tunable, allowing manually specify which interrupts driver allowed to use. Unluckily, many BIOSes program wrong allowed interrupts mask, so driver tries to stay on safe side by not using unshareable ISA IRQs. This option gives control over this limitation, allowing more per-CPU timers to be provided, when FSB interrupts are not supported. Value of this tunable is bitmask. - Do not use regular interrupts on virtual machines. QEMU and VirtualBox do not support them properly, that may cause problems. Stay safe by default. Same time both QEMU and VirtualBox work fine in legacy_route mode. VirtualBox also works fine if manually specify allowed ISA IRQs with above.

It can be suitable for HPETs without FSB interrupts support, as it gives them two unshared IRQs. It allows them to provide one per-CPU event timer on dual-CPU system, that should be suitable for further tickless kernels.

SVN rev 209371 on 2010-06-20 21:33:29Z by mav Implement new event timers infrastructure. It provides unified APIs for writing event timer drivers, for choosing best possible drivers by machine independent code and for operating them to supply kernel with hardclock(), statclock() and profclock() events in unified fashion on various hardware. Infrastructure provides support for both per-CPU (independent for every CPU core) and global timers in periodic and one-shot modes. MI management code at this moment uses only periodic mode, but one-shot mode use planned for later, as part of tickless kernel project. For this moment infrastructure used on i386 and amd64 architectures. Other archs are welcome to follow, while their current operation should not be affected. This patch updates existing drivers (i8254, RTC and LAPIC) for the new order, and adds event timers support into the HPET driver. These drivers have different capabilities: LAPIC - per-CPU timer, supports periodic and one-shot operation, may freeze in C3 state, calibrated on first use, so may be not exactly precise. HPET - depending on hardware can work as per-CPU or global, supports periodic and one-shot operation, usually provides several event timers. i8254 - global, limited to periodic mode, because same hardware used also as time counter. RTC - global, supports only periodic mode, set of frequencies in Hz limited by powers of 2. Depending on hardware capabilities, drivers preferred in following orders, either LAPIC, HPETs, i8254, RTC or HPETs, LAPIC, i8254, RTC. User may explicitly specify wanted timers via loader tunables or sysctls: kern.eventtimer.timer1 and kern.eventtimer.timer2. If requested driver is unavailable or unoperational, system will try to replace it. If no more timers available or "NONE" specified for second, system will operate using only one timer, multiplying it's frequency by few times and uing respective dividers to honor hz, stathz and profhz values, set during initial setup.

Fix a few minor issues based on a bug report and reading over the HPET spec: - Use read/modify/write cycles to enable and disable the HPET instead of writing 0 to reserved bits. - Shutdown the HPET during suspend as encouraged by the spec. - Fail to attach to an HPET with a period of zero.

Fix the HPET table probe routine to run from device_identify() instead of directly from acpi0. Before it would attach prior to the sysresource devices, causing the later allocation of its memory range to fail and print a warning like "acpi0: reservation of fed00000, 1000 (3) failed". Use an explicit define for our probe order base value of 10. Help from: jhb Tested by: Abdullah Ibn Hamad Al-Marri <almarrie / gmail.com> MFC after: 3 days Approved by: re

Dynamically choose the quality of the ACPI timer depending on whether the fast or safe/slow method is in use. Fast remains at 1000, slow is now at 850 (always preferred to TSC). Since the HPET has proven slower than ACPI-fast on some systems, drop its quality to 900. In the future, it is hoped that HPET performance will improve as it is the main timer Intel supports. HPET may move back to 2000 in -current once RELENG_7 is branched to ensure that it gets tested. Approved by: re

The HPET appears to be broken on silby's Acer Pentium M system, never advancing. Read from the timer before attaching to be sure it advances in 1 us. Since the slowest rate allowed by the spec is 10 MHz, the timer is guaranteed to change in this interval if it is working. Tested by: Rui Paulo Approved by: re MFC after: 3 days
