Hi Greg, Sasha, and David, I noticed a regression report in bugzilla.kernel.org that seems to be specific to the linux-6.6.y series: Quoting from https://bugzilla.kernel.org/show_bug.cgi?id=218484 : > After upgrading to version 6.6.16, the kernel compilation on a i586 > arch (on a 32bit chroot in a 64bit host) fails with a message: > > virtual memory exhausted: Cannot allocate memory > > this happens even lowering the number of parallel compilation > threads. On a x86_64 arch the same problem doesn't occur. It's not > clear whether some weird recursion is triggered that exhausts the > memory, but it seems that the problem is caused by the patchset > 'minmax' added to the 6.6.16 version, in particular it seems caused > by these patches: > > - minmax-allow-min-max-clamp-if-the-arguments-have-the-same-signedness.patch > - minmax-fix-indentation-of-__cmp_once-and-__clamp_once.patch > - minmax-allow-comparisons-of-int-against-unsigned-char-short.patch > - minmax-relax-check-to-allow-comparison-between-unsigned-arguments-and-signed-constants.patch > > Reverting those patches fixes the memory exhaustion problem during compilation. The reporter later added: > From a quick test the same problem doesn't occur in 6.8-rc4. See the ticket for more details. Note, you have to use bugzilla to reach the reporter, as I sadly[1] can not CCed them in mails like this. [TLDR for the rest of this mail: I'm adding this report to the list of tracked Linux kernel regressions; the text you find below is based on a few templates paragraphs you might have encountered already in similar form.] BTW, let me use this mail to also add the report to the list of tracked regressions to ensure it's doesn't fall through the cracks: #regzbot introduced: 204c653d5d0c79940..9487d93f172acef https://bugzilla.kernel.org/show_bug.cgi?id=218484 #regzbot title: minmax: virtual memory exhausted in 6.6.16 with i586 chroot #regzbot ignore-activity Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) -- Everything you wanna know about Linux kernel regression tracking: https://linux-regtracking.leemhuis.info/about/#tldr If I did something stupid, please tell me, as explained on that page.
