Hi, I'm interested in trying to port qhypstub to msm8953 for my old phone Xiaomi Redmi 6 Pro. But I don't know how the find the two addresses mentioned in README . Would someone be so kind to tell me that if there are any documents available？

Thanks a lot!

Sadly the Snapdragon 410 is pretty much the only Qualcomm chipset with a basic set of public documentation. I'm not aware of any public documentation for MSM8953. :(

However, if I remember correctly the main problem you will have on MSM8953 is that it actually does not have a separate hyp firmware. The hypervisor level is likely skipped in the tz firmware, or something like that. You can verify this by checking if your device has a hyp partition.

I've tried. You're right, there isn't a hyp partition on my device.

$ fastboot erase hyp
erasing 'hyp'...
FAILED (remote: Partition table doesn't exist
)
finished. total time: 0.031s

Thanks anyway. I'll close this issue.
