* sh: Convert sh to use read/update_persistent_clockJohn Stultz2010-03-041-5/+1
| | | | | | | | | | | | This patch converts the sh architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future.

| * sh: Fix up clockevents broadcasting.Paul Mundt2009-08-191-4/+0
| | | | | | | | | | | | | | | | | | This fixes up the clockevents broadcasting code as detailed in commit ee348d5a1d810bc9958cabb7c27302aab235d36e ("[ARM] realview: fix broadcast tick support"). This saves us from having to do strange ordering things with the broadcast clockevent device, relying on the rating instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: hwblk base implementationMagnus Damm2009-07-041-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is the hwblk base implementation, containing structures and shared functions dealing with hardware blocks. A each processor model should provide a list of hwblks and describe which module stop bit that is associated with each hwblck and how the hwblks are grouped together into areas. The shared code keeps track of the usage count for each hwblk and the areas. Fallback implementations for processor specific code are also kept as weak symbols. The clock framework, the runtime pm code and cpuidle will all tie into this hwblk implementation. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Bump the earlytimer probe devices up.Paul Mundt2009-06-141-2/+7
| | | | | | | | | | Presently the earlytimer probe handles the clockevents driver, which requires that the clockevents driver be registered first. This bumps it up by 1 to include the clocksource device, which can be safely ignored if it doesn't exist, as we will simply error out on that path and defer to the jiffies clocksource.

* sh: Use generic sched_clock().Paul Mundt2009-06-141-5/+0
| | | | | | | The generic sched_clock() handles INITIAL_JIFFIES now as well, so we can just use that instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Bump the earlytimer bits back to time_init().Paul Mundt2009-06-141-11/+6
| | | | | | | | | | These were handled through late_time_init due to kmalloc() and friends not being available earlier on previously. Now with slab caches being available much earlier, this is no longer necessary, and we can move the initialization up to an earlier point. One of the benefits with this is that printk times are available a bit earlier! Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Kill off the remnants of the old timer code.Paul Mundt2009-05-121-27/+2

* sh: Account for INITIAL_JIFFIES when using jiffies clocksource.Paul Mundt2009-05-111-1/+1
| | | | | | | | In the case where we fall back on the generic jiffies clocksource, INITIAL_JIFFIES needs to be accounted for so that printk times aren't completely skewed. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | Now that all of the possible users for rtc_lock have gone away, it is no longer necessary to keep this lock definition around.

* sh: Wire up GENERIC_CMOS_UPDATE for the platforms that need it.Paul Mundt2009-05-081-0/+14
| | | | | | | | | | Now that everything has converted over to generic timekeeping, we need an alternate method for keeping the RTC updated for those platforms that are still using the rtc_sh_get/set_time pairs, presently limited to SH-03 and the Dreamcast. This wires up the GENERIC_CMOS_UPDATE hooks for those to maintain the same behaviour. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: clockevent/clocksource/hrtimers/nohz TMU support.Paul Mundt2007-05-091-117/+55
| | | | | | | | | | | | | | | | | | | This adds basic support for clockevents and clocksources, presently only implemented for TMU-based systems (which are the majority of SH-3 and SH-4 systems). The old NO_IDLE_HZ implementation is also dropped completely, the only users of this were on TMU-based systems anyways. More work needs to be done to generalize the TMU handling, in that the current implementation is rather tied to the notion of TMU0 and TMU1 utilization. Additionally, as more SH timers switch over to this scheme, we'll be able to gut most of the remaining system timer infrastructure that existed before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Turn off IRQs around get_timer_offset() calls.Paul Mundt2006-12-061-4/+9
| | | | | | | | | Since all of the sys_timer sources currently do this on their own within the ->get_offset() path, it's more sensible to just have the caller take care of it when grabbing xtime_lock. Incidentally, this is more in line with what others (ie, ARM) are doing already. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: First step at generic timeofday support.Paul Mundt2006-10-061-0/+2
| | | | | | | | | | | | | At the moment we wrap GENERIC_TIME around our existing timer API. As boards start providing their own clocksources, they're able to select GENERIC_TIME accordingly and optimize out most of the timer API. Once the current timers have been reworked as proper clocksource drivers, the rest of the place holders for the timer API can go away and we can flip on GENERIC_TIME unconditionally.

* [PATCH] kill wall_jiffiesAtsushi Nemoto2006-10-011-9/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies. So we can kill wall_jiffies completely. This is just a cleanup and logically should not change any real behavior except for one thing: RTC updating code in (old) ppc and xtensa use a condition "jiffies - wall_jiffies == 1". This condition is never met so I suppose it is just a bug. I just remove that condition only instead of kill the whole "if" block.

* [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)Atsushi Nemoto2006-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390 timer interrupt handler with this change. Currently update_times() calculates ticks by "jiffies - wall_jiffies", but callers of do_timer() should know how many ticks to update. Passing ticks get rid of this redundant calculation. Also there are another redundancy pointed out by Martin Schwidefsky. This cleanup make a barrier added by 5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes it. As a bonus, this cleanup make wall_jiffies can be removed easily, since now wall_jiffies is always synced with jiffies. (This patch does not really remove wall_jiffies. It would be another cleanup patch) Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: "Eric W.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
