This results in all\nthese cores with the same physical_core_id using the same entry in the\nrapl_counter_info_perdomain[]. Since rapl_perf_init() skips the\nperf-initialization for cores whose domain_ids have already been\nvisited, cores that have the same physical_core_id always read the\nperf file corresponding to the physical_core_id of the first package\nand thus the package-energy is incorrectly reported to be the same\nvalue for different packages.\n\nNote: This issue only arises when RAPL counters are read via perf and\nnot when they are read via MSRs since in the latter case the MSRs are\nread separately on each core.\n\nFix this issue by associating each CPU with rapl_core_id which is\nunique across all the packages in the system.\n\nFixes: 05a2f07db888 (\"tools/power turbostat: read RAPL counters via perf\")\nSigned-off-by: Gautham R.

Fix regression of waiting a long time on updating trace event filters\n\n When the faultable trace points were added, it needed task trace RCU\n synchronization.\n\n This was added to the tracepoint_synchronize_unregister() function.\n The filter logic always called this function whenever it updated the\n trace event filters before freeing the old filters. This increased\n the time of \"trace-cmd record\" from taking 13 seconds to running over\n 2 minutes to complete.\n\n Move the freeing of the filters to call_rcu*() logic, which brings\n the time back down to 13 seconds.\n\n - Fix ring_buffer_subbuf_order_set() error path lock protection\n\n The error path of the ring_buffer_subbuf_order_set() released the\n mutex too early and allowed subsequent accesses to setting the\n subbuffer size to corrupt the data and cause a bug.\n\n By moving the mutex locking to the end of the error path, it prevents\n the reentrant access to the critical data and also allows the\n function to convert the taking of the mutex over to the guard()\n logic.\n\n - Remove unused power management clock events\n\n The clock events were added in 2010 for power management. In 2011 arm\n used them. In 2013 the code they were used in was removed. These\n events have been wasting memory since then.\n\n - Fix sparse warnings\n\n There was a few places that sparse warned about trace_events_filter.c\n where file-\u003efilter was referenced directly, but it is annotated with\n an __rcu tag.

There are still some more small tweaks left to be done\n here, and those patches are still out for review and arguing among\n the different hardware companies, but this is a major step forward\n and a great example of how to do upstream development well.\n\n - small number of thunderbolt fixes and updates, things seem to be\n slowing down here (famous last words...)\n\n - xhci refactors and reworking to try to handle some rough corner\n cases in some hardware implementations where things don\u0027t always\n work properly\n\n - typec driver updates\n\n - USB3 power management reworking and updates\n\n - Removal of some old and orphaned UDC gadget drivers that had not\n been used in a very long time, dropping over 11 thousand lines from\n the tree, always a nice thing, making up for the 12k lines added\n for the USB offload feature.\n\n - lots of little updates and fixes in different drivers\n\n All of these have been in linux-next for over 2 weeks, the USB offload\n logic has been in there for 8 weeks now, with no reported issues\"\n\n* tag \u0027usb-6.16-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (172 commits)\n ALSA: usb-audio: qcom: fix USB_XHCI dependency\n ASoC: qdsp6: fix compile-testing without CONFIG_OF\n usb: misc: onboard_usb_dev: fix build warning for CONFIG_USB_ONBOARD_DEV_USB5744\u003dn\n usb: typec: tipd: fix typo in TPS_STATUS_HIGH_VOLAGE_WARNING macro\n USB: typec: fix const issue in typec_match()\n USB: gadget: udc: fix const issue in gadget_match_driver()\n USB: gadget: fix up const issue with struct usb_function_instance\n USB: serial: pl2303: add new chip PL2303GC-Q20 and PL2303GT-2AB\n USB: serial: bus: fix const issue in usb_serial_device_match()\n usb: usbtmc: Fix timeout value in get_stb\n usb: usbtmc: Fix read_stb function and get_stb ioctl\n ALSA: qc_audio_offload: try to reduce address space confusion\n ALSA: qc_audio_offload: avoid leaking xfer_buf allocation\n ALSA: qc_audio_offload: rename dma/iova/va/cpu/phys variables\n ALSA: usb-audio: qcom: Fix an error handling path in qc_usb_audio_probe()\n usb: misc: onboard_usb_dev: Fix usb5744 initialization sequence\n dt-bindings: usb: ti,usb8041: Add binding for TI USB8044 hub controller\n usb: misc: onboard_usb_dev: Add support for TI TUSB8044 hub\n usb: gadget: lpc32xx_udc: Use USB API functions rather than constants\n usb: gadget: epautoconf: Use USB API functions rather than constants\n ...\n" }, { "commit": "378ec25aec5a8444879f8696d580c94950a1f1df", "tree": "db4fc794dc959351ea03d7da8e9b422b79e41b07", "parents": [ "c26f4fbd58375bd6ef74f95eb73d61762ad97c59", "b495021a973e2468497689bd3e29b736747b896f" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 06 12:32:02 2025 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Jun 06 12:32:02 2025 -0700" }, "message": "Merge tag \u0027tty-6.16-rc1\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty\n\nPull tty/serial updates from Greg KH:\n \"Here is the big set of tty and serial driver changes for 6.16-rc1.\n\n A little more churn than normal in this portion of the kernel for this\n development cycle, Jiri and Nicholas were busy with cleanups and\n reviews and fixes for the vt unicode handling logic which composed\n most of the overall work in here.\n\n Major changes are:\n\n - vt unicode changes/reverts/changes from Nicholas.
