https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234778 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 can 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 issue, 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 v1.2 board) runs fine on v1.1 board. I can't see any significant differences between 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. -- You are receiving this mail because: You are the assignee for the bug.home | help
