kernel/time/clocksource.c needs struct task_struct on m68k

2007-03-09T18:50:30+00:00

kernel/time/clocksource.c needs struct task_struct on m68k.

Because it uses spin_unlock_irq(), which, on m68k, uses hardirq_count(), which
uses preempt_count(), which needs to dereference struct task_struct, we
have to include sched.h. Because it would cause a loop inclusion, we
cannot include sched.h in any other of asm-m68k/system.h,
linux/thread_info.h, linux/hardirq.h, which leaves this ugly include in
a C file as the only simple solution.

[PATCH] clocksource: add usage of CONFIG_SYSFS

2006-12-10T17:57:22+00:00

Simply adds some ifdefs to remove clocksoure sysfs code when CONFIG_SYSFS
isn't turn on.

[PATCH] time: rename clocksource functions

2006-06-26T16:58:21+00:00

As suggested by Roman Zippel, change clocksource functions to use
clocksource_xyz rather then xyz_clocksource to avoid polluting the
namespace.

[PATCH] Time: i386 Clocksource Drivers

2006-06-26T16:58:21+00:00

Implement the time sources for i386 (acpi_pm, cyclone, hpet, pit, and tsc).
With this patch, the conversion of the i386 arch to the generic timekeeping
code should be complete.

The patch should be fairly straight forward, only adding the new clocksources.

[PATCH] Time: Use clocksource infrastructure for update_wall_time

2006-06-26T16:58:20+00:00

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] Time: Clocksource Infrastructure

2006-06-26T16:58:20+00:00

This introduces the clocksource management infrastructure.  A clocksource is a
driver-like architecture generic abstraction of a free-running counter.  This
code defines the clocksource structure, and provides management code for
registering, selecting, accessing and scaling clocksources.

Additionally, this includes the trivial jiffies clocksource, a lowest common
denominator clocksource, provided mainly for use as an example.
