Merge tag 'trace-ringbuffer-v7.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-tracePull ring-buffer fixes from Steven Rostedt: - Fix reporting MISSED EVENTS in trace iterator When the "trace" file is read with tracing enabled, if the writer were to pass the iterator reader, it resets, sets a "missed_events" flag and continues. The tracing output checks for missed events and if there are some, it prints out "[LOST EVENTS]" to let the user know events were dropped. But the clearing of the missed_events happened when the tracing system queried the ring buffer iterator about missed events. This was premature as the ring buffer is per CPU, and the tracing code reads all the CPU buffers and checks for missed events when it is read. If the CPU iterator that had missed events isn't printed next, the output for the LOST EVENTS is lost. Clear the missed_events flag when the iterator moves to the next event and not when the missed_events flag is queried. Also clear it on reset. - Flush and stop the persistent ring buffer on panic On panic the persistent ring buffer is used to debug what caused the panic. But on some architectures, it requires flushing the memory from cache, otherwise, the ring buffer persistent memory may not have the last events and this could also cause the ring buffer to be corrupted on the next boot. - Fix nr_subbufs initialization in simple_ring_buffer_init_mm The remote simple ring buffer meta data nr_subbufs is initialized too early and gets cleared later on, making it zero and not reflect the actual number of sub-buffers. - Fix unload_page for simple_ring_buffer init rollback On error, the pages loaded need to be unloaded. To unload a page it is expected that: page = load_page(va); -> unload_page(page). But the code was doing: unload_page(va) and not unload_page(page). - Create output file from cmd_check_undefined The check for undefined symbols checks if the file *.o.checked exists and if so it skips doing the work. But the *.o.checked file never was created making every build do the work even when it was already done previously.* tag 'trace-ringbuffer-v7.1-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Create output file from cmd_check_undefined tracing: Fix unload_page for simple_ring_buffer init rollback tracing: Fix nr_subbufs initialization in simple_ring_buffer_init_mm() ring-buffer: Flush and stop persistent ring buffer on panic ring-buffer: Fix reporting of missed events in iterator List of files: /linux/arch/s390/include/asm/Kbuild

Thu, 30 Apr 2026 05:28:16 +0200

ring-buffer: Flush and stop persistent ring buffer on panicOn real hardware, panic and machine reboot may not flush hardware cacheto memory. This means the persistent ring buffer, which relies on acoherent state of memory, may not have its events written to the bufferand they may be lost. Moreover, there may be inconsistency with thecounters which are used for validation of the integrity of thepersistent ring buffer which may cause all data to be discarded.To avoid this issue, stop recording of the ring buffer on panic andflush the cache of the ring buffer's memory.Fixes: e645535a954a ("tracing: Add option to use memmapped memory for trace boot instance")Cc: stable@vger.kernel.orgCc: Will Deacon Cc: Mathieu Desnoyers Cc: Ian Rogers Link: https://patch.msgid.link/177751969602.2136606.12031934362587643488.stgit@mhiramat.tok.corp.google.comSigned-off-by: Masami Hiramatsu (Google) Acked-by: Catalin Marinas Acked-by: Geert Uytterhoeven Signed-off-by: Steven Rostedt List of files: /linux/arch/s390/include/asm/Kbuild

Merge tag 'perf-core-2026-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull performance event updates from Ingo Molnar: "x86 PMU driver updates: - Add support for the core PMU for Intel Diamond Rapids (DMR) CPUs (Dapeng Mi) Compared to previous iterations of the Intel PMU code, there's been a lot of changes, which center around three main areas: - Introduce the OFF-MODULE RESPONSE (OMR) facility to replace the Off-Core Response (OCR) facility - New PEBS data source encoding layout - Support the new "RDPMC user disable" feature - Likewise, a large series adds uncore PMU support for Intel Diamond Rapids (DMR) CPUs (Zide Chen) This centers around these four main areas: - DMR may have two Integrated I/O and Memory Hub (IMH) dies, separate from the compute tile (CBB) dies. Each CBB and each IMH die has its own discovery domain. - Unlike prior CPUs that retrieve the global discovery table portal exclusively via PCI or MSR, DMR uses PCI for IMH PMON discovery and MSR for CBB PMON discovery. - DMR introduces several new PMON types: SCA, HAMVF, D2D_ULA, UBR, PCIE4, CRS, CPC, ITC, OTC, CMS, and PCIE6. - IIO free-running counters in DMR are MMIO-based, unlike SPR. - Also add support for Add missing PMON units for Intel Panther Lake, and support Nova Lake (NVL), which largely maps to Panther Lake. (Zide Chen) - KVM integration: Add support for mediated vPMUs (by Kan Liang and Sean Christopherson, with fixes and cleanups by Peter Zijlstra, Sandipan Das and Mingwei Zhang) - Add Intel cstate driver to support for Wildcat Lake (WCL) CPUs, which are a low-power variant of Panther Lake (Zide Chen) - Add core, cstate and MSR PMU support for the Airmont NP Intel CPU (aka MaxLinear Lightning Mountain), which maps to the existing Airmont code (Martin Schiller) Performance enhancements: - Speed up kexec shutdown by avoiding unnecessary cross CPU calls (Jan H. Schönherr) - Fix slow perf_event_task_exit() with LBR callstacks (Namhyung Kim) User-space stack unwinding support: - Various cleanups and refactorings in preparation to generalize the unwinding code for other architectures (Jens Remus) Uprobes updates: - Transition from kmap_atomic to kmap_local_page (Keke Ming) - Fix incorrect lockdep condition in filter_chain() (Breno Leitao) - Fix XOL allocation failure for 32-bit tasks (Oleg Nesterov) Misc fixes and cleanups: - s390: Remove kvm_types.h from Kbuild (Randy Dunlap) - x86/intel/uncore: Convert comma to semicolon (Chen Ni) - x86/uncore: Clean up const mismatch (Greg Kroah-Hartman) - x86/ibs: Fix typo in dc_l2tlb_miss comment (Xiang-Bin Shi)"* tag 'perf-core-2026-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (58 commits) s390: remove kvm_types.h from Kbuild uprobes: Fix incorrect lockdep condition in filter_chain() x86/ibs: Fix typo in dc_l2tlb_miss comment x86/uprobes: Fix XOL allocation failure for 32-bit tasks perf/x86/intel/uncore: Convert comma to semicolon perf/x86/intel: Add support for rdpmc user disable feature perf/x86: Use macros to replace magic numbers in attr_rdpmc perf/x86/intel: Add core PMU support for Novalake perf/x86/intel: Add support for PEBS memory auxiliary info field in NVL perf/x86/intel: Add core PMU support for DMR perf/x86/intel: Add support for PEBS memory auxiliary info field in DMR perf/x86/intel: Support the 4 new OMR MSRs introduced in DMR and NVL perf/core: Fix slow perf_event_task_exit() with LBR callstacks perf/core: Speed up kexec shutdown by avoiding unnecessary cross CPU calls uprobes: use kmap_local_page() for temporary page mappings arm/uprobes: use kmap_local_page() in arch_uprobe_copy_ixol() mips/uprobes: use kmap_local_page() in arch_uprobe_copy_ixol() arm64/uprobes: use kmap_local_page() in arch_uprobe_copy_ixol() riscv/uprobes: use kmap_local_page() in arch_uprobe_copy_ixol() perf/x86/intel/uncore: Add Nova Lake support ...
