the BIG cores are online on my device with CONFIG_ARM64_ERRATUM_1319367=y. Tasks seem to be scheduled to them as well. Also corrupted TLBs don't sound particularly fun to me. Are you sure I should disable that option?

unexpected! so I built a kernel with this enabled and the two cores didn't come up, and specifically listed this erratum in error. rebuilding with the sole change of disabling the erratum brought the cores up. I AM using maxcpus=4 uboot option.

I used linaro arm 9.2 cross compiler on an amd64 system.

if this is working for you then the issue must be on my side. thoughts?
