Hi Everyone,
We are using k2h EVM with processor sdk linux 06_01_00_08 prebuild image and root file system,
During the boot, we are seeing following in the boot logs,
0.100032] smp: Bringing up secondary CPUs ... [ 0.174552] CPU1: thread -1, cpu 1, socket 0, mpidr 80000001 [ 0.174559] CPU1: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable [ 0.244638] CPU2: thread -1, cpu 2, socket 0, mpidr 80000002 [ 0.244644] CPU2: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable [ 0.314714] CPU3: thread -1, cpu 3, socket 0, mpidr 80000003 [ 0.314720] CPU3: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable [ 0.314837] smp: Brought up 1 node, 4 CPUs [ 0.314847] SMP: Total of 4 processors activated (1600.00 BogoMIPS). [ 0.314854] CPU: All CPU(s) started in HYP mode.
In the older MCSKD keystone ARM CPU was in SVC mode, will be there any performace issue in HYP mode?
and is this impact of "CPU1: Spectre v2: firmware did not set auxiliary control register IBE bit, system vulnerable" .
Regards,
Snehal
