Drop the APB-timer TSC calibration, which hasn't been used since the removal of Moorestown support by commit 1a8359e411eb ("x86/mid: Remove Intel Moorestown").

2011-06-27clocksource: apb: Share APB timer code with other platformsJamie Iles1-20/+2
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 <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: "H.

2011-06-09x86: i8253: Consolidate definitions of global_clock_eventRalf Baechle1-1/+0
There are multiple declarations of global_clock_event in header files specific to particular clock event implementations. Consolidate them in <asm/time.h> and make sure all users include that header.

2010-08-12x86, cleanup: Remove obsolete boot_cpu_id variableRobert Richter1-1/+0
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 <[email protected]> LKML-Reference: <[email protected]> Signed-off-by: H. Peter Anvin <[email protected]>
2010-05-19x86, mrst: add more timer config optionsJacob Pan1-1/+0
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.

2010-02-24x86, apbt: Moorestown APB system timer driverJacob Pan1-0/+70
Moorestown platform does not have PIT or HPET platform timers. Instead it has a bank of eight APB timers. The number of available timers to the os is exposed via SFI mtmr tables. All APB timer interrupts are routed via ioapic rtes and delivered as MSI. Currently, we use timer 0 and 1 for per cpu clockevent devices, timer 2 for clocksource.
