[Xen-devel] [PATCH v2 11/14] x86/hvm: Move saving/loading vcpu's TSC to common code

Both VMX and SVM save/load vcpu's TSC when saving/loading vcpu's context, so this patch moves saving/loading vcpu's TSC to the common functions hvm_[save|load]_cpu_ctxt(). Signed-off-by: Haozhong Zhang Acked-by: Jan Beulich ---

[Xen-devel] [PATCH v2 09/14] x86/hvm: Setup TSC scaling ratio

[Xen-devel] [PATCH v2 00/14] Add VMX TSC scaling support

This patchset adds support for VMX TSC scaling feature which is available on Intel Skylake Server CPU. The specification of VMX TSC scaling can be found at http://www.intel.com/content/www/us/en/processors/timestamp-counter-scaling-virtualization-white-paper.html VMX TSC scaling allows guest TSC

[Xen-devel] [PATCH v2 03/14] x86/time.c: Use correct guest TSC frequency in tsc_set_info()

When TSC_MODE_PVRDTSCP is used for a HVM container and TSC scaling is available, use the non-zero value of argument gtsc_khz of tsc_set_info() as the guest TSC frequency rather than using the host TSC frequency. Otherwise, TSC scaling will not be able get the correct ratio between the host and

[Xen-devel] [PATCH v2 08/14] x86/hvm: Collect information of TSC scaling ratio

Both VMX TSC scaling and SVM TSC ratio use the 64-bit TSC scaling ratio, but the number of fractional bits of the ratio is different between VMX and SVM. This patch adds the architecture code to collect the number of fractional bits and other related information into fields of struct

[Xen-devel] [PATCH v2 04/14] x86/time.c: Use correct guest TSC frequency in tsc_get_info()

When the TSC mode of a HVM container is TSC_MODE_DEFAULT or TSC_MODE_PVRDTSCP and no TSC emulation is used, the existing tsc_get_info() uses the host TSC frequency (cpu_khz) as the guest TSC frequency. However, tsc_set_info() may set the guest TSC frequency to a value different than the host. In

[Xen-devel] [PATCH v2 05/14] x86/hvm: Scale host TSC when setting/getting guest TSC

The existing hvm_[set|get]_guest_tsc_fixed() calculate the guest TSC by adding the TSC offset to the host TSC. When the TSC scaling is enabled, the host TSC should be scaled first. This patch adds the scaling logic to those two functions. Signed-off-by: Haozhong Zhang

[Xen-devel] [PATCH v2 06/14] x86/time.c: Scale host TSC in pvclock properly
