> Hi,
Hello Hanjun,
We tested your v5 patch set (and added some GICv3 patches) on Hisilicon ARM64 SoC hardware,
from your change log for v6, there is only one functional change to fix the NULL pointer, I think
the test result is still valid for v6, please refer to the test result below [1].
We can boot the system successfully using PSCI on our ARM64 hardware using this patch set, of course
we need to add some more patches (GICv3), but with this patch set:
You could add my Tested-by: Yijing Wang <wangyijing@xxxxxxxxxx> if you want.
if you want me to test the new version of patch set, please let me know, thanks.
