clocksource: apb: Share APB timer code with other platforms

2011-06-27T22:16:21Z

The APB timers are an IP block from Synopsys (DesignWare APB timers) and are also found in other systems including ARM SoC's. This patch adds functions for creating clock_event_devices and clocksources from APB timers but does not do the resource allocation. This is handled in a higher layer to allow the timers to be created from multiple methods such as platform_devices. Cc: Thomas Gleixner Cc: Ingo Molnar Cc: "H.

x86: i8253: Consolidate definitions of global_clock_event

There are multiple declarations of global_clock_event in header files specific to particular clock event implementations. Consolidate them in and make sure all users include that header.

x86, cleanup: Remove obsolete boot_cpu_id variable

2010-08-12T21:01:38Z

boot_cpu_id is there for historical reasons and was renamed to boot_cpu_physical_apicid in patch: c70dcb7 x86: change boot_cpu_id to boot_cpu_physical_apicid However, there are some remaining occurrences of boot_cpu_id that are never touched in the kernel and thus its value is always 0. This patch removes boot_cpu_id completely. Signed-off-by: Robert Richter LKML-Reference: <1279731838-1522-8-git-send-email-robert.richter@amd.com> Signed-off-by: H. Peter Anvin

x86, mrst: add more timer config options

2010-05-19T20:45:39Z

Always-on local APIC timer (ARAT) has been introduced to Medfield, along with the platform APB timers we have more timer configuration options between Moorestown and Medfield. This patch adds run-time detection of avaiable timer features so that we can treat Medfield as a variant of Moorestown and set up the optimal timer options for each platform. i.e. Medfield: per cpu always-on local APIC timer Moorestown: per cpu APB timer Manual override is possible via cmdline option x86_mrst_timer.
