Merge tag 'timers-v7.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/daniel.lezcano/linux into timers/clocksource - Use designated initializers for sh_mtu2, sh_cmt, and sh_tmu, and drop the unused initializer in the platform_device_id table for sh_mtu2 (Uwe Kleine-König) - Remove redundant dev_err()/dev_err_probe() messages when devm_request_*_irq() fails, as the helper already logs an error message (Pan Chuang) - Fix a boot hang on Allwinner D1 when a forced minimum delta is used with the sun4i timer (Felix Yan) - Fix an IRQ leak in the cpuhp_setup_state() error path by freeing the IRQ on failure in the NXP PIT driver (WenTao Liang) - Fix incorrect unmapping of shared MMIO between the clocksource and clockevent drivers. If one of them fails to initialize, the error path unmaps the shared MMIO region, leaving the other driver with an invalid mapping on clps711x (Guangshuo Li) - Make the samsung_pwm driver compatible with PREEMPT_RT by replacing regular spinlocks with raw_spinlock_t in atomic contexts (Marek Szyprowski) - Use __raw_readl() and __raw_writel() instead of ioread32() and iowrite32() to support SWAP_IO_SPACE in the rtl-otto driver (Rustam Adilov) - Fix a missing clk_disable_unprepare() call in the timer initialization error path of the Armada driver (Yuho Choi)Link: https://lore.kernel.org/lkml/75feea31-683d-45a1-87f4-ab045e0152ae@oss.qualcomm.com List of files: /linux/kernel/irq/debugfs.h

Merge tag 'irq-core-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tipPull interrupt core updates from Thomas Gleixner: - Rework of /proc/interrupt handling: /proc/interrupts was subject to micro optimizations for a long time, but most of the low hanging fruit was left on the table. This rework addresses the major time consuming issues: - Printing a long series of zeros one by one via a format string instead of counting subsequent zeros and emitting a string constant. - Simplify and cache the conditions whether interrupts should be printed - Use a proper iteration over the interrupt descriptor xarray instead of walking and testing one by one. - Provide helper functions for the architecture code to emit the architecture specific counters - Convert the counter structure in x86 to an array, which simplifies the output and add mechanisms to suppress unused architecture interrupts, which just occupy space for nothing. Adopt the new core mechanisms. This adjusts the gdb scripts related to interrupt counter statistics to work with the new mechanisms. - Prevent a string overflow in the /proc/irq/$N/ directory name creation code.* tag 'irq-core-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip: x86/irq: Add missing 's' back to thermal event printout genirq/proc: Speed up /proc/interrupts iteration genirq/proc: Runtime size the chip name genirq: Expose irq_find_desc_at_or_after() in core code genirq: Add rcuref count to struct irq_desc genirq/proc: Increase default interrupt number precision to four genirq: Calculate precision only when required genirq: Cache the condition for /proc/interrupts exposure genirq/manage: Make NMI cleanup RT safe genirq: Expose nr_irqs in core code scripts/gdb: Update x86 interrupts to the array based storage x86/irq: Move IOAPIC misrouted and PIC/APIC error counts into irq_stats x86/irq: Suppress unlikely interrupt stats by default x86/irq: Make irqstats array based genirq/proc: Utilize irq_desc::tot_count to avoid evaluation genirq/proc: Avoid formatting zero counts in /proc/interrupts x86/irq: Optimize interrupts decimals printing genirq/proc: Size interrupt directory names for 10-digit interrupt numbers List of files: /linux/kernel/irq/debugfs.h

61b51a167c524b65a59b1342e70c2008d514a796 - genirq/proc: Runtime size the chip name

Sun, 17 May 2026 22:02:44 +0200

genirq/proc: Runtime size the chip nameThe chip name column in the /proc/interrupt output is 8 characters andright aligned, which causes visual clutter due to the fixed length and thealignment. Many interrupt chips, e.g. PCI/MSI[X] have way longer names.Update the length when a chip is assigned to an interrupt and utilize thisinformation for the output. Align it left so all chip names start at thebegin of the column.Update the GDB script as well and disentangle the header maze so itactually works with all .config combinations.Signed-off-by: Thomas Gleixner Tested-by: Michael Kelley Reviewed-by: Dmitry Ilvokhin Link: https://patch.msgid.link/20260517194932.085786035@kernel.org List of files: /linux/kernel/irq/debugfs.h
