gdb: invalid register name 'ttbr1_el1' 'elr_el1'

[clingfei]

When debugging use gdb, I want to view the value in some system registers such as elr_el1, ttbr1_el1, tcr_el1,..., etc. However, it gdb can not identicate these registers. Does m1n1 support them?

I dont think so you can access system register with gdb..... there should be some other way around... if you are running macos on VM then you can access these using "re re --all" ... however on what system(specs) you are running m1n1?

Thanks for your reply. I am not running macos on VM.
I boot asahi under hypervisor as target and use another asahi as host, following to the steps in this document(Tethered Boot Setup (For Developers)). And i run gdbserver in hypervisor console, connect gdb to it and start debugging.
If I boot linux on qemu, and connect gdb to qemu, I can access these system register just like " i r TTBR1_EL1".
