* Use the local APIC timer to drive the various kernel clocks on SMP machinesjhb2005-02-081-19/+19
| | | | | | | | | | | | | | | | | | | | | | | rather than forwarding interrupts from the clock devices around using IPIs: - Add an IDT vector that pushes a clock frame and calls lapic_handle_timer(). - Add functions to program the local APIC timer including setting the divisor, and setting up the timer to either down a periodic countdown or one-shot countdown. - Add a lapic_setup_clock() function that the BSP calls from cpu_init_clocks() to setup the local APIC timer if it is going to be used. The setup uses a one-shot countdown to calibrate the timer. We then program the timer on each CPU to fire at a frequency of hz * 3. stathz is defined as freq / 23 (hz * 3 / 23), and profhz is defined as freq / 2 (hz * 3 / 2). This gives the clocks relatively prime divisors while keeping a low LCM for the frequency of the clock interrupts. Thanks to Peter Jeremy for suggesting this approach. - Remove the hardclock and statclock forwarding code including the two associated IPIs. The bitmap IPI handler has now effectively degenerated to just IPI_AST. - When the local APIC timer is used we don't turn the RTC on at all, but we still enable interrupts on the ISA timer 0 (i8254) for timecounting purposes.

* Improve sync recovery algorithm:gibbs2004-08-271-97/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Remove PSM_SYNCERR_THRESHOLD1. This value specified how many sync errors were required before the mouse is re-initialised. Re-initialisation is now done after (packetsize * 2) sync errors as things aren't likely to improve after that. o Reset lastinputerror when re-initialisation occurs. We don't want to continue to drop data after re-initialisation. o Count the number of failed packets independently of the syncerrors statistic. syncerrors is useful for recovering sync within a single packet. pkterrors allows us to detect when the mouse changes its packet mode due to some external event (e.g. KVM switch). o Reinitialize the mouse if we see more than psmpkterrthresh errors during the validation period. The validation period begins as soon as a sync error is detected and continues until psmerrsecs/msecs time has elapsed. The defaults for these two values force a reset if we see two packet errors in a 2 second period. This allows rapid detection of packet framing errors caused by the mouse changing packet modes. o Export psmpkterrthresh as a sysctl o Export psmloglevel as a sysctl. o Enable more debugging code to be enabled at runtime via psmloglevel. o Simplify verbose conditioned loging by using a VLOG macro. o Add several comments describing the sync recovery algorithm of this driver.

In the case of many KVM's, this avoids a bug in their mouse emulation that sends back incorrect sync when you explicitly request a data packet from the mouse.

* Partially revert previous commit. Calling getit() unconditionally fixedmarcel2004-07-111-11/+22
| | | | | | | | | | | | | | a problem that could also be fixed differently without reverting previous attempts to fix DELAY while the debugger is active (rev 1.204). The bug was that the i8254 implements a countdown timer, while for (k)db_active a countup timer was implemented. This resulted in premature termination and consequently the breakage of DELAY. The fix (relative to rev 1.211) is to implement a countdown timer for the kdb_active case. As such the ability to step clock initialization is preserved and DELAY does what is expected of it.
