--- Comment #9 from Mark Millard <marklmi26-f...@yahoo.com> --- (In reply to Mark Millard from comment #8) I've tried a 1 GiByte aarch64 context for a -j4 buildworld buildkernel . . . I had a RPi3 that was based on head -r358966 do a build world buildkernel of the same version, from scratch, -j4 style. The RPi3 is a 1 GiByte RAM context. I had 3072 GiBytes for the swap partition. That ,and the ufs file system, were on a USB SSD, not the microsd card. The build completed without any /var/log/message or console output during the build. My modified version of top reported (details copied from a ssh window) . . . For Mem: 738512Ki MaxObsActive, 190608Ki MaxObsWired, 906372Ki MaxObs(Act+Wir) For Swap: 1927Mi MaxObsUsed (top was started before the build. "MaxObs" is short for "Maximum Observed".) The build took a few minutes under 31 hrs. The build used (my PINE64 media are also set up to boot the RPi3, explaining some naming): vm.pageout_oom_seq=120 vm.pfault_oom_attempts=-1 vfs.root.mountfrom="ufs:/dev/gpt/PINE642Groot" dumpdev="/dev/gpt/PINE642Gswp2" /dev/gpt/PINE642Groot / ufs rw,noatime 1 1 /dev/gpt/PINE642Gswap none swap sw 0 0 (So this avoided the microsd card for ufs and swap/page space.) Overall, it looks like having more than 2 GiBytes of swap partition is appropriate for -j4 : 1927 MiByte is not much less than 2048 MiByte. But, with appropriate configuration anyway, the RPi3 can do buildworld buildkernel for head 13, even -j4 style. This was aarch64. armv7 style with 1 GiByte RAM does not allow as much swap/page space without complaining at boot. It does not appear that such a -j4 build would be appropriate for armv7. But I've not investigated what would fit. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ freebsd-toolchain@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-toolchain To unsubscribe, send any mail to "freebsd-toolchain-unsubscr...@freebsd.org"
