Got it installed, but am now having some interesting problems.
# getconf _NPROCESSORS_ONLN
# head /sys/devices/system/cpu/cpu*/online
==> /sys/devices/system/cpu/cpu0/online <==
==> /sys/devices/system/cpu/cpu1/online <==
==> /sys/devices/system/cpu/cpu2/online <==
==> /sys/devices/system/cpu/cpu3/online <==
For whatever reason, CPUs 1-3 are offline and refuse to come online:
# cd /sys/devices/system/cpu
# echo 1 > cpu1/online
# cat cpu1/online
dmesg says its booting the CPU then shuts it right back down. Unfortunately it doesn't provide any insight into this decision:
[ 2051.521460] CPU1: Booted secondary processor
[ 2051.521727] tegra_cpu_init : emc_clk->min_rate to 204M
[ 2051.525034] Switched to NOHz mode on CPU #1
[ 2051.615318] cpu_down(1)+
[ 2051.907510] CPU1: shutdown
[ 2051.914031] cpu_down(1)-
[ 2052.398490] cpu ext_temperature=36
Anyone seen this before and/or have solutions?
Also, is there a git tree for this kernel? Where's the boot configuration stored (e.g kernel image, boot command line, etc)?
