[PATCH V2 11/12] hv_balloon: fix bugs in num_pages_onlined accounting

From: Vitaly Kuznetsov Our num_pages_onlined accounting is buggy: 1) In case we're offlining a memory block which was present at boot (e.g. when there was no hotplug at all) we subtract 32k from 0 and as num_pages_onlined is unsigned get a very big positive number. 2) Commit 6df8d9aaf3af (

From: Vitaly Kuznetsov We have a mix of different ideas of which loglevel should be used. Unify on the following: - pr_info() for normal operation - pr_warn() for 'strange' host behavior - pr_err() for all errors. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y. Srinivasan --- drivers/hv/

[PATCH V2 08/12] Drivers: hv: vmbus: Implement Direct Mode for stimer0

From: Michael Kelley The 2016 version of Hyper-V offers the option to operate the guest VM per-vcpu stimer's in Direct Mode, which means the timer interupts on its own vector rather than queueing a VMbus message. Direct Mode reduces timer processing overhead in both the hypervisor and the guest,

[PATCH 1/1] Drivers: hv: vmbus: Fix ring buffer signaling

From: Michael Kelley Fix bugs in signaling the Hyper-V host when freeing space in the host->guest ring buffer: 1. The interrupt_mask must not be used to determine whether to signal on the host->guest ring buffer 2. The ring buffer write_index must be read (via hv_get_bytes_to_write) *after

[PATCH 2/4] Drivers: hv: vmbus: do not mark HV_PCIE as perf_device

From: Dexuan Cui The pci-hyperv driver's channel callback hv_pci_onchannelcallback() is not really a hot path, so we don't need to mark it as a perf_device, meaning with this patch all HV_PCIE channels' target_cpu will be CPU0. Signed-off-by: Dexuan Cui Cc: sta...@vger.kernel.org Cc: Stephen He
