Good morning. This is your Linux Kernel Daily weekly recap for June 8th through 15th, 2026.
Zero pull request activity items and 30 additional commits this week, all delivered through Linus Torvalds' merge activity from subsystem maintainer trees.
This week represents one of the most significant timer infrastructure updates in recent memory, with coordinated changes across timing, interrupt handling, and hardware support that will improve system performance and expand platform compatibility.
The standout theme is precision timing modernization. The kernel gained expanded timekeeping snapshot mechanisms that now support auxiliary clocks and expose underlying hardware counter values to userspace. This affects PTP implementations, allowing better control and steering for time-sensitive applications. The…
Virtual timer support saw major architectural improvements, particularly for ARM EL2 virtual timers with corresponding ACPI changes, and comprehensive cleanup of MIPS VDSO handling. The MIPS changes are especially significant - they eliminate unnecessary VDSO mappings when no capable clocksource is available,…
Interrupt handling performance received substantial optimization. The…
