Drivers: hv: vmbus: Use the new infrastructure for delivering VMBUS interrupts

2013-02-27T18:15:53Z

Use the infrastructure for delivering VMBUS interrupts using a special vector. With this patch, we can now properly handle the VMBUS interrupts that can be delivered on any CPU. Also, turn on interrupt load balancing as well. This patch requires the infrastructure that was implemented in the patch: X86: Handle Hyper-V vmbus interrupts as special hypervisor interrupts Signed-off-by: K. Y.

x86, hyperv: HYPERV depends on X86_LOCAL_APIC

2013-02-13T01:46:23Z

In order to compile in the special Hyper-V interrupt vector, we need infrastructure in arch/x86/apic/apic.c. At least for now, simply require CONFIG_X86_LOCAL_APIC in order to enable CONFIG_HYPERV.

Drivers: hv: balloon: Prevent the host from ballooning the guest too low

2013-02-08T23:42:01Z

Based on the amount of memory being managed set a floor on how low the guest can be ballooned. Signed-off-by: K. Y. Srinivasan Reviewed-by: Haiyang Zhang Signed-off-by: Greg Kroah-Hartman

Drivers: hv: balloon: Add a parameter to delay pressure reporting

2013-02-08T23:42:01Z

Delay reporting memory pressure by a specified amount of time. This addresses the problem where the host may take memory balancing decisions based on incorrect memory pressure data that will be posted as soon as the balloon driver is loaded. Signed-off-by: K. Y.

Drivers: hv: balloon: Make adjustments to the pressure report

2013-01-30T05:06:07Z

The host expects that the pressure report includes the pressure due to the pages that have been ballooned. Make necessary adjustments to reflect that. Also, include the free memory information in the pressure report. Signed-off-by: K. Y. Srinivasan Signed-off-by: Greg Kroah-Hartman
