no enable-method?
As the rk3228 also does not have a pmu, does the newly created
"rockchip,rk3036-smp" work for you?
unlucky, that doesn't work...and our 3.10 kernel is using psci for
rk3228's smp ops, maybe i should check that too, but i know nothing
about psci for now :(
Using PSCI on more rockchip socs will make the ARM people very happy ;-) .
So definitly no argument from me against it. I guess you should only need the
enable-method and psci node you should already have in your 3.10 dts, to
actually enable it.
cpu@xxx {
enable-method = "psci";
};
psci {
compatible = "arm,psci-0.2";
...
};
But we can of course add that in a later patch as well.
Heiko
yes, you're right~
after added psci node and enabled CONFIG_ARM_PSCI, it could bring up all
cpus :
[ 0.090371] CPU0: thread -1, cpu 0, socket 15, mpidr 80000f00
[ 0.091018] Setting up static identity map for 0x60100000 - 0x60100058
[ 0.095260] CPU1: thread -1, cpu 1, socket 15, mpidr 80000f01
[ 0.096648] CPU2: thread -1, cpu 2, socket 15, mpidr 80000f02
[ 0.098070] CPU3: thread -1, cpu 3, socket 15, mpidr 80000f03
[ 0.098228] Brought up 4 CPUs
[ 0.100145] SMP: Total of 4 processors activated (192.00 BogoMIPS).
[ 0.100732] CPU: All CPU(s) started in SVC mode.
patch coming :)
