[PATCH] x86-64: get rid of ARCH_HAVE_XTIME_LOCK

2007-02-13T12:26:21Z

ARCH_HAVE_XTIME_LOCK is used by x86_64 arch . This arch needs to place a read only copy of xtime_lock into vsyscall page. This read only copy is named __xtime_lock, and xtime_lock is defined in arch/x86_64/kernel/vmlinux.lds.S as an alias. So the declaration of xtime_lock in kernel/timer.c was guarded by ARCH_HAVE_XTIME_LOCK define, defined to true on x86_64. We can get same result with _attribute__((weak)) in the declaration. linker should do the job. Signed-off-by: Eric Dumazet Signed-off-by: Andi Kleen Cc: Andi Kleen Signed-off-by: Andrew Morton

[PATCH] Add const for time{spec,val}_compare arguments

2007-02-11T18:51:31Z

The arguments are really const. Mark them const to allow these functions being called from places where the arguments are const without getting useless compiler warnings. Signed-off-by: Rolf Eike Beer Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] per-task-delay-accounting: setup

2006-07-15T04:53:56Z

Initialization code related to collection of per-task "delay" statistics which measure how long it had to wait for cpu, sync block io, swapping etc. The collection of statistics and the interface are in other patches. This patch sets up the data structures and allows the statistics collection to be disabled through a kernel boot parameter.

[PATCH] x86_64: Add useful constants to time.h

2006-06-26T17:48:19Z

In timekeeping code, one often does need to use conversion constants. Naming these leads to code that's easier to understand, showing the reader between which units the conversion is made. Signed-off-by: Vojtech Pavlik Signed-off-by: Andi Kleen Signed-off-by: Linus Torvalds

[PATCH] Time: Introduce arch generic time accessors

2006-06-26T16:58:20Z

Introduces clocksource switching code and the arch generic time accessor functions that use the clocksource infrastructure. Signed-off-by: John Stultz Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Time: Use clocksource infrastructure for update_wall_time

2006-06-26T16:58:20Z

Modify the update_wall_time function so it increments time using the clocksource abstraction instead of jiffies. Since the only clocksource driver currently provided is the jiffies clocksource, this should result in no functional change. Additionally, a timekeeping_init and timekeeping_resume function has been added to initialize and maintain some of the new timekeping state.

[PATCH] hrtimers: remove nsec_t typedef

2006-03-26T16:57:03Z

nsec_t predates ktime_t and has mostly been superseded by it. In the few places that are left it's better to make it explicit that we're dealing with 64 bit values here.

[PATCH] sys_alarm() unsigned signed conversion fixup

2006-03-25T16:22:48Z

alarm() calls the kernel with an unsigend int timeout in seconds. The value is stored in the tv_sec field of a struct timeval to setup the itimer. The tv_sec field of struct timeval is of type long, which causes the tv_sec value to be negative on 32 bit machines if seconds > INT_MAX. Before the hrtimer merge (pre 2.6.16) such a negative value was converted to the maximum jiffies timeout by the timeval_to_jiffies conversion. It's not clear whether this was intended or just happened to be done by the timeval_to_jiffies code. hrtimers expect a timeval in canonical form and treat a negative timeout as already expired. This breaks the legitimate usage of alarm() with a timeout value > INT_MAX seconds. For 32 bit machines it is therefor necessary to limit the internal seconds value to avoid API breakage. Instead of doing this in all implementations of sys_alarm the duplicated sys_alarm code is moved into a common function in itimer.c Signed-off-by: Thomas Gleixner Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
