[Bug 198909] KPTI: acpi_pm_finish: 10x performance regression on XPS 13 9360
https://bugzilla.kernel.org/show_bug.cgi?id=198909 --- Comment #9 from Chen Yu (yu.c.c...@intel.com) --- Wait...or maybe you can just test only tracking acpi_pm_finish() by: 1. append no_console_suspend in grub 2. after boot up, echo acpi_pm_finish > /sys/kernel/debug/tracing/set_graph_function 3. do the test 4. provide dmesg and /sys/kernel/debug/tracing/trace -- You are receiving this mail because: You are watching the assignee of the bug. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla

https://bugzilla.kernel.org/show_bug.cgi?id=198909 --- Comment #8 from Chen Yu (yu.c.c...@intel.com) --- @Esokrarkose @Paul Do you have a change to test with pm-graph using -f option? It might take some time to generate/parse the html result, but it is very helpful to narrow down at which stage it is most time-consuming. -- You are receiving this mail because: You are watching the assignee of the bug. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla

I also have a Dell XPS 13 9360 on hand, but can not reproduce the issue. I'm using 4.16-rc4 kernel, and the acpi_pm_finish always takes around 21ms. in your case, does the long latency and short latency happens in the same boot? or is the behavior consistent (always long or always short) for a single boot? -- You are receiving this mail because: You are watching the assignee of the bug. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla

But I don't think PTI could be dynamically turned off/on during suspend/resume, could you provide pm-suspend with -f to see the backtrace of this stage -- You are receiving this mail because: You are watching the assignee of the bug. -- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ___ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
