https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234778 Bug ID: 234778 Summary: Only 1 CPU core out of 4 is usable on RPi2 v1.2 Product: Base System Version: 12.0-STABLE Hardware: arm OS: Any Status: New Severity: Affects Only Me Priority: --- Component: arm Assignee: freebsd-arm@FreeBSD.org Reporter: t_uemura@macome.co.jp The architecture of recent 12-STABLE for RPi2 (32 bit) is armv7, rather than armv6 on 11-STABLE. This means that there is a chance that the same build c= an run also on RPi2 v1.2 equipped with the newer ARMv8 based BCM2837 SoC. Actually, the build works almost perfectly on v1.2 board except one big iss= ue, that only 1 CPU logical core is used/assigned to all processes and the remaining 3 cores are completely ignored, despite all 4 cores are listed in top, for example. This doesn't happen on v1.1 board. The same microSD (just pulled out from v= 1.2 board) runs fine on v1.1 board. I can't see any significant differences bet= ween both boards in top, dmesg or sysctl output. The OS is r341492, rpi-firmware is 1.20180619 or the GIT rev. 077fbe8 (as of 6th Dec. 2018) and u-boot is 2018.11. --=20 You are receiving this mail because: You are the assignee for the bug.=
