| | * | | perf stat: Use common printout function to avoid duplicated codeAndi Kleen2015-11-041-37/+20Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of every caller deciding whether to call abs or nsec printout do it all in a single central function. No functional changes.

This reduces the dependency of Bzy_MHz calculation on the TSC. Previously, there were 4 TSC readings required in each caculation, the raw TSC delta combined with the measurement_interval. This also removes the "tsc_tweak" correction factor used when TSC runs on a different base clock from the CPU's bclk. After this change, tsc_tweak is used only for %Busy. The end-result should be a Bzy_MHz result slightly less prone to jitter. Signed-off-by: Len Brown <len.brown@intel.com>

This fix hides offlined cores where topology cannot be accessed. With a recent kernel patch suggested from Prarit Bhargava it may be possible that soft offlined cores' topology can still be parsed.

And since it looks like the syscall ABI is inconsistent on arm-compat, so we must work around it (and document it) in the test.

We add two scripts: - pstore_crash_test This script causes kernel crash and reboot. It is executed by 'make run_pstore_crash' in selftests. It can also be used with kdump. - pstore_post_reboot_tests This script includes test cases which check pstore's behavior after crash and reboot. It is executed together with pstore_tests by 'make run_tests [-C pstore]' in selftests. The test cases in pstore_post_reboot_tests are currently following. - Check pstore backend is registered - Mount pstore filesystem - Check dmesg/console/pmsg files exist in pstore filesystem - Check dmesg/console files contain oops end marker - Check pmsg file properly keeps the content written before crash - Remove all files in pstore filesystem Example usage is following.

There were a handful of development topics this cycle, dax get_user_pages, dax fsync, and raw block dax, that need more more iteration and will wait for 4.5. The patches to make devm and the pmem driver NUMA aware have been in -next for several weeks. The hot-add support has not, but is contained to the NFIT driver and is passing unit tests. The coredump support is straightforward and was looked over by Jeff. All of it has received a 0day build success notification across 107 configs. Summary: - Add support for the ACPI 6.0 NFIT hot add mechanism to process updates of the NFIT at runtime. - Teach the coredump implementation how to filter out DAX mappings. - Introduce NUMA hints for allocations made by the pmem driver, and as a side effect all devm allocations now hint their NUMA node by default" * tag 'libnvdimm-for-4.4' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: coredump: add DAX filtering for FDPIC ELF coredumps coredump: add DAX filtering for ELF coredumps acpi: nfit: Add support for hot-add nfit: in acpi_nfit_init, break on a 0-length table pmem, memremap: convert to numa aware allocations devm_memremap_pages: use numa_mem_id devm: make allocations numa aware by default devm_memremap: convert to return ERR_PTR devm_memunmap: use devres_release() pmem: kill memremap_pmem() x86, mm: quiet arch_add_memory()

From this, evaluate the _FIT ACPI method which returns the updated NFIT with handles for the hot-plugged NVDIMM. Iterate over the new NFIT, and add any new tables found, and register/enable the corresponding regions. In the nfit test framework, after normal initialization, update the NFIT with a new hot-plugged NVDIMM, and directly call into the driver to update its view of the available regions.
