From: Sean Christopherson Date: Fri, 17 Jan 2025 23:42:03 +0000 (-0800) Subject: KVM: selftests: Print out the actual Top-Down Slots count on failure X-Git-Tag: v6.15-rc1~195^2~9^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=54108e73344480c3e5f3799129970009f52c59f4;p=thirdparty%2Flinux.git KVM: selftests: Print out the actual Top-Down Slots count on failure Print out the expected vs. actual count of the Top-Down Slots event on failure in the Intel PMU counters test. GUEST_ASSERT() only expands constants/macros, i.e. only prints the value of the expected count, which makes it difficult to debug and triage failures.
