| * cpumask: convert struct clock_event_device to cpumask pointers.Rusty Russell2008-12-131-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Impact: change calling convention of existing clock_event APIs struct clock_event_timer's cpumask field gets changed to take pointer, as does the ->broadcast function. Another single-patch change. For safety, we BUG_ON() in clockevents_register_device() if it's not set. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Ingo Molnar <mingo@elte.hu>
* | at91: warn if irqs are enabled in set_next_eventUwe Kleine-König2008-12-121-0/+9
|/ | | | | | | | | | | | | Thomas claims that irqs are disabled when set_next_event is called. But David and Remy claim they saw irqs being enabled here. As both sides don't seem to have time to investigate here, start with a warning that might trigger if the problem still exists.

* [ARM] 4539/1: clocksource and clockevents for at91rm9200David Brownell2007-10-121-65/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GENERIC_TIME and GENERIC_CLOCKEVENTS support for the at91rm9200. - Oneshot mode (used for NO_HZ and high res timers) uses the alarm to emulate a real oneshot timer; the trickiest bit is how to avoid some lowlevel races. Thanks to Remy Bohmer for various fixes to this code. - Tighten up periodic mode support using the PIT. - Streamline reads of the 32KHz counter. Thanks to Marc Pignat for some testing results: the CRTR register has *very* odd behavior. The reread appears to work around stranger glitches than just getting an old clock value (which would quickly self-correct). - Remove the rounding-up of tick_usec to 10.009 msec (32KiHz/100), since that no longer acts correct (time increases too fast). Note that the at91sam9 and at91x40 chips need other solutions, since they don't have the same system timer module.

* [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor2007-02-081-0/+146
Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
