This checks the failure that was fixed by kernel commit edde99ce0529 ("KVM: Write protect memory after slot swap"). Two threads are used; a guest thread continuously updates a shared variable, which is also sampled by a host thread that also checks if dirty logging marked it as dirty. It detects about 5 million failures with the fix reverted, and 0 failures with the fix applied. Signed-off-by:Avi Kivity <avi@redhat.com> Signed-off-by:

This patch provides a way to establish an "identity" guest which has a 1:1 gva->hva translation. This allows the host to switch to guest mode, call a function in the same address space, and return. Because long mode virtual addresses are 47 bits long, and some hosts have smaller physical addresses, we target 32-bit mode only. On x86_64 the code needs to be run with 'setarch i386 -3' to limit the address space to 3GB, so the address space occupied by the local APIC is left unused. Signed-off-by:

Just figured out that it makes a lot of sens to measure the latency of stgi and clgi too in this test. Here is an updated one. >From 350d33d155db8928f81cc801587787c84d6bc8c5 Mon Sep 17 00:00:00 2001 From: Joerg Roedel <joerg.roedel@amd.com> Date: Sun, 19 Sep 2010 15:34:37 +0200 Subject: [PATCH] svm: Add VMLOAD/VMSAVE and STGI/CLGI latency test This patch adds a test to measure the latency of the VMLOAD and VMSAVE instructions as well as for STGI and CLGI.

This patch implements three tests for kvmclock. First one check whether the date of time returned by kvmclock matches the value got from host. Second one check whether the cycle of kvmclock grows monotonically in smp guest and the count of warps and stalls are also recorded. The last test is a performance test to measure the guest cycles cost when trying to read cycle of kvmclock. Three parameters were accepted by the test: test loops, seconds since 1970-01-01 00:00:00 UTC which could be easily get through date +%s and the max accepted offset value between the tod of guest and host.

Most of the codes were borrowed from arxh/x86/kernel/kvmclock.c. A special bit: PV_CLOCK_CYCLE_RAW_TEST_BIT is used to notify the driver to return unadjusted cycles. Signed-off-by:
