[PATCH] clocksource: Fix thinko in watchdog selection

2007-03-25T21:57:34Z

The watchdog implementation excludes low res / non continuous clocksources from being selected as a watchdog reference unintentionally. Allow using jiffies/PIT as a watchdog reference as long as no better clocksource is available. This is necessary to detect TSC breakage on systems, which have no pmtimer/hpet. The main goal of the initial patch (preventing to switch to highres/nohz when no reliable fallback clocksource is available) is still guaranteed by the checks in clocksource_watchdog().

[PATCH] dynticks: fix hrtimer rounding error in next_timer_interrupt

2007-03-25T21:57:34Z

The rework of next_timer_interrupt() fixed the timer wheel bugs, but invented a rounding error versus the next hrtimer event. This is caused by the conversion of the hrtimer internal representation to relative jiffies. This causes bug #8100: http://bugzilla.kernel.org/show_bug.cgi?id=8100 next_timer_interrupt() returns "now" in such a case and causes the code in tick_nohz_stop_sched_tick() to trigger the timer softirq, which is bogus as no timer is due for expiry. This results in an endless context switching between idle and ksoftirqd until a timer is due for expiry. Modify the hrtimer evaluation so that, it returns now + 1, when the conversion results in a delta < 1 jiffie. It's confirmed to resolve bug #8100 Reported-by: Emil Karlson Signed-off-by: Thomas Gleixner Signed-off-by: Linus Torvalds

After dvb tuner refactoring, the pllbuff has been altered such that the pll address is now stored in buf[0]. Instead of sending buf to set_pll_input, we should send buf+1. Signed-off-by: Michael Krufky Cc: Mauro Carvalho Chehab Cc: Ivan Andrewjeski Signed-off-by: Linus Torvalds

[ARM] 4278/1: configure pxa27x I2C SCL as "input"

2007-03-24T23:24:39Z

It has been reported by Julian Deng that configuring the pxa27x i2c SCL line as output generates a short negative pulse on it during the call to pxa_gpio_mode(GPIO117_I2CSCL_MD); as it first switches it to output and then configures it for the alternate function. The SCL line is in fact bidirectional and can also be configured as 117 | GPIO_ALT_FN_1_IN, in which case the pulse is not generated. This is exactly what this patch does.

[PATCH] i386: Prevent early access to TSC to avoid crash on TSCless systems

2007-03-24T22:45:53Z

commit f9690982b8c2f9a2c65acdc113e758ec356676a3 removed the check for cpu_khz from sched_clock(), which prevented early access to the TSC by non obvious magic. This is harmless as long as the CPU has a TSC. On TSCless systems this results in an illegal instruction trap. Replace tsc_disabled and tsc_unstable by tsc_enabled, which is only set when the tsc is available and not unstable. Signed-off-by: Thomas Gleixner Acked-by: Ingo Molnar Signed-off-by: Linus Torvalds
