xtensa: remove CCOUNT_PER_JIFFY

2013-09-06T16:48:59Z

Use ccount_freq directly to make the code a little more readable. Signed-off-by: Baruch Siach Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa: fix !CONFIG_XTENSA_CALIBRATE_CCOUNT build failure

2013-09-06T16:48:51Z

Commits 925f5532 (xtensa: ccount based clockevent implementation) and e3f43291 (xtensa: ccount based sched_clock) introduced users of ccount_freq. This variable doesn't exist when CONFIG_XTENSA_CALIBRATE_CCOUNT is disabled. Add ccount_freq definition in this case.

xtensa: delete __cpuinit usage from all xtensa files

2013-07-14T23:36:56Z

The __cpuinit type of throwaway sections might have made sense some time ago when RAM was more constrained, but now the savings do not offset the cost and complications. For example, the fix in commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time") is a good example of the nasty type of bugs that can be created with improper use of the various __init prefixes. After a discussion on LKML[1] it was decided that cpuinit should go the way of devinit and be phased out. Once all the users are gone, we can then finally remove the macros themselves from linux/init.h. Note that some harmless section mismatch warnings may result, since notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c) are flagged as __cpuinit -- so if we remove the __cpuinit from arch specific callers, we will also get section mismatch warnings. As an intermediate step, we intend to turn the linux/init.h cpuinit content into no-ops as early as possible, since that will get rid of these warnings. In any case, they are temporary and harmless. This removes all the arch/xtensa uses of the __cpuinit macros from all C files. Currently xtensa does not have any __CPUINIT used in assembly files.

xtensa: cleanup ccount frequency tracking

xtensa: add IRQ domains support

2012-12-19T05:10:23Z

IRQ domains provide a mechanism for conversion of linux IRQ numbers to hardware IRQ numbers and vice versus. It is used by OpenFirmware for linking device tree objects to their respective interrupt controllers. Signed-off-by: Max Filippov Signed-off-by: Chris Zankel

xtensa:fix the incompatible pointer type warning in time.c

2012-12-19T05:10:20Z

Fix the definition of the function ccount_read to be compatible to the member read of the structure clocksource. Signed-off-by: Wanlong Gao Signed-off-by: Chris Zankel

clocksource: xtensa: Convert to clocksource_register_hz/khz

2011-11-22T03:01:04Z

This converts the xtensa clocksource to use clocksource_register_hz/khz This is untested, so any assistance in testing would be appreciated! CC: Chris Zankel CC: Thomas Gleixner Signed-off-by: John Stultz

xtensa: Switch do_timer() to xtime_update()

2011-01-31T13:55:46Z

xtime_update() takes the xtime_lock itself. set_linux_timer() does not need to be protected by xtime_lock.
