[patch V6 00/16] Improve /proc/interrupts further
From: Thomas Gleixner
Date: Sun May 17 2026 - 16:01:35 EST
This is a follow up to v5 which can be found here:
https://lore.kernel.org/20260401195625.213446764@xxxxxxxxxx
The v1 cover letter contains a full analysis, explanation and numbers:
https://lore.kernel.org/20260303150539.513068586@xxxxxxxxxx
TLDR:
- The performance of reading of /proc/interrupts has been improved
piecewise over the years, but most of the low hanging fruit has been
left on the table.
Changes vs. V5:
- Rebased against v7.1-rc2
- Addressed some formatting/alignment details - Radu, Michael
- Fixed some 0-day fallout vs. various Kconfig combinations
- Picked up tags where appropriate
Delta patch against v5 is below.
The series applies on top of v7.1-rc2 and is also available via git:
git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git irq-proc-v6
Thanks,
tglx
