I get an "out of memory" error when building Linux kernels 5.15.164, 5.15.165 and 5.15.166-rc1: ... cc1: out of memory allocating 180705472 bytes after a total of 283914240 bytes ... make[4]: *** [scripts/Makefile.build:289: drivers/staging/media/atomisp/pci/isp/kernels/ynr/ynr_1.0/ia_css_ynr.host.o] Error 1 ...
I found a work around for this problem.
Remove the six minmax patches introduced with kernel 5.15.164:
minmax: allow comparisons of 'int' against 'unsigned char/short' minmax: allow min()/max()/clamp() if the arguments have the same minmax: clamp more efficiently by avoiding extra comparison minmax: fix header inclusions minmax: relax check to allow comparison between unsigned arguments minmax: sanity check constant bounds when clamping
Can these 6 patches be removed or fixed?
It's a bit late, as we rely on them for other changes.
Perhaps just fixes for the files that you are seeing build crashes on? I know a bunch of them went into Linus's tree for this issue, but we didn't backport them as I didn't know what was, and was not, needed. If you can pinpoint the files that cause crashes, I can dig them up.
The first one to fail on 5.15.164 was: drivers/media/pci/solo6x10/solo6x10-core.o
So I found and applied this patch to 5.15.164: [PATCH] media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)
What is the git commit id of that change? I can't seem to find it.
31e97d7c9ae3
From Salvatore Bonaccorso to stable on 22 Aug 2024 19:19:27 +0200
Subject: Please apply commit 31e97d7c9ae3 ("media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)") to 6.1.y ... "Note I suspect it is required as well for 5.15.164 (as the commits were backported there as well and 31e97d7c9ae3 now missing there)"
Then the next to fail on 5.15.164 was: drivers/staging/media/atomisp/pci/isp/kernels/ynr/ynr_1.0/ia_css_ynr.host.o
What .c file is this happening for?
Probably this one: drivers/staging/media/atomisp/pci/isp/kernels/ynr/ynr_1.0/ia_css_ynr.host.c
