Subject: [PATCH 0/8] powerpc/book3s64: Hash / SLB fixes & improvements
Date: Sat, 30 Aug 2025 09:21:39 +0530 [thread overview]
Message-ID: <cover.1756522067.git.ritesh.list@gmail.com> (raw)
Hello all,
While working over SLB related multi-hit issue we identified few more Hash / SLB
related issues, which this patch series fixes.
Patches 1-4 are various fixes related to SLB / HASH MMU.
Patches 5-8 are improvements in ptdump, slb preload and the last patch adds slb
user and kernel vmstat counters.
Patch-1 was posted earlier as a standalone fix here [1]. It has no changes
in this version. But since patch-6 is dependent on this, hence we clubbed all
Hash / SLB related patches into a common series.
Other than patch-1 (which was posted earlier), the rest of the patches are
mostly only tested in Qemu tcg for powernv and pseries. I will be testing these
on the real HW too before the next revision. But meanwhile it will be good to
get any reviews/feedback.
