[PATCH v2 00/13] selftests/resctrl: resctrl_val() related cleanups & improvements

by Ilpo Järvinen

Hi all, This series does a number of cleanups into resctrl_val() and generalizes it by removing test name specific handling from the function. One of the changes improves MBA/MBM measurement by narrowing down the period the resctrl FS derived memory bandwidth numbers are measured over. My feel is it didn't cause noticeable difference into the numbers because they're generally good anyway except for the small number of outliers. To see the impact on outliers, I'd need to setup a test to run large number of replications and do a statistical analysis, which I've not spent my time on. Even without the statistical analysis, the new way to measure seems obviously better and makes sense even if I cannot see a major improvement with the setup I'm using. This series has some conflicts with SNC series from Maciej and also with the MBA/MBM series from Babu. -- i. v2: - Resolved conflicts with kselftest/next - Spaces -> tabs correction Ilpo Järvinen (13): selftests/resctrl: Convert get_mem_bw_imc() fd close to for loop selftests/resctrl: Calculate resctrl FS derived mem bw over sleep(1) only selftests/resctrl: Consolidate get_domain_id() into resctrl_val() selftests/resctrl: Use correct type for pids selftests/resctrl: Cleanup bm_pid and ppid usage & limit scope selftests/resctrl: Rename measure_vals() to measure_mem_bw_vals() & document selftests/resctrl: Add ->measure() callback to resctrl_val_param selftests/resctrl: Add ->init() callback into resctrl_val_param selftests/resctrl: Simplify bandwidth report type handling selftests/resctrl: Make some strings passed to resctrlfs functions const selftests/resctrl: Convert ctrlgrp & mongrp to pointers selftests/resctrl: Remove mongrp from MBA test selftests/resctrl: Remove test name comparing from write_bm_pid_to_resctrl() tools/testing/selftests/resctrl/cache.c | 6 +- tools/testing/selftests/resctrl/cat_test.c | 5 +- tools/testing/selftests/resctrl/cmt_test.c | 21 +- tools/testing/selftests/resctrl/mba_test.c | 34 ++- tools/testing/selftests/resctrl/mbm_test.c | 33 ++- tools/testing/selftests/resctrl/resctrl.h | 48 ++-- tools/testing/selftests/resctrl/resctrl_val.c | 269 ++++++------------ tools/testing/selftests/resctrl/resctrlfs.c | 55 ++-- 8 files changed, 224 insertions(+), 247 deletions(-) -- 2.39.2

[PATCH v1 0/5] Add support for the Idle HLT intercept feature

by Manali Shukla

The upcoming new Idle HLT Intercept feature allows for the HLT instruction execution by a vCPU to be intercepted by the hypervisor only if there are no pending V_INTR and V_NMI events for the vCPU. When the vCPU is expected to service the pending V_INTR and V_NMI events, the Idle HLT intercept won’t trigger. The feature allows the hypervisor to determine if the vCPU is actually idle and reduces wasteful VMEXITs. Presence of the Idle HLT Intercept feature is indicated via CPUID function Fn8000_000A_EDX[30]. Document for the Idle HLT intercept feature will be available in the next version of "AMD64 Architecture Programmer’s Manual". Testing Done: Added a selftest to test the Idle HLT intercept functionality. Tested SEV and SEV-ES guest for the Idle HLT intercept functionality.
