similar to: [PATCH V2] xen/arm: implement smp_call_function

smp_call_function and smp_call_function_single are almost complete duplicates of the same logic. This patch combines them by implementing them in terms of the more general smp_call_function_mask(). [ Jan, Andi: This only changes arch/i386; can x86_64 be changed in the same way? ] [ Rebased onto Jan's x86_64-mm-consolidate-smp_send_stop patch ] Signed-off-by: Jeremy Fitzhardinge

Short of getting an explanation for the odd difference to native, make the code match native (and also, in the case of x86-64, __smp_call_function_single()). As usual, written and tested against 2.6.24-rc3 and made apply against 2.6.18 without further testing.

Currently, enable/disable turbo mode on AMD is broken: $ xenpm enable-turbo-mode 0 <-- works and proper CPU MSR bit is set $ xenpm enable-turbo-mode 1 <-- silently broken, MSR bit not set Since ->turbo is per policy, when user requests to enable/disable turbo mode, we need to set the bit in all of the ->cpus that this policy affects. --- xen/arch/x86/acpi/cpufreq/powernow.c | 2

Attached and below are a patch that unifies the shutdown code paths in Xen, including those from EARLY_FAIL. This will facilitate the use of Intel(R) TXT for measured launch by ensuring that all shutdowns will call the necessary hook to tear down the measured environment. It also centralizes any future shutdown-related changes. The patch also postpones clearing the online status APs in

This adds an smp_ops for voyager, and hooks things up appropriately. This is the first baby-step to making subarch runtime switchable.

We need to write the irq number to GICC_DIR on the physical cpu that previously received the interrupt, but currently we are doing it on the pcpu that received the maintenance interrupt. As a consequence if a vcpu is migrated to a different pcpu, the irq is going to be EOI''ed on the wrong pcpu. This covers the case where dom0 vcpu0 is running on pcpu1 for example (you can test this

Hi, This is the fifth version of this patch series. With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen relies on it to set the logical ID and the GIC, it won''t be possible to use Xen with this use case. This patch series is divided in 3 parts: - Patch 1: prepare Xen

Currently cpufreq and xenpm are out of sync. Fix cpufreq reporting of if turbo mode is enabled or not. Fix xenpm to not decode for tristate, but a boolean.

A NO_IDLE_HZ implementation is provided for i386 VMI builds. When a VCPU enters its idle loop, it disables its periodic alarm and sets up a one shot alarm for the next time event. That way, it does not become ready to run just to service the periodic alarm interrupt. Instead, it can remain halted until there is some real work pending for it. This allows the hypervisor to use the physical
