Hashcat on AMD 780M

[darkside]

I wanted to play a little with hashcat on my laptop. I remember that some time ago I was able to run it, but currently there is an error I don't know how to solve.

System: arch Linux
Ryzen 7840U with 780M GPU

Code:

[font=monospace][color=#000000]hashcat -I [/color]
hashcat (v6.2.6) starting in backend information mode

After running hashcat I get:

see line

error: unknown argument: '-flegacy-pass-manager'

This error was mentioned in this forum before, not quite sure whether this has something todo with AMD/HIP or LLVM

LLVM on the hand removed this flag some time ago but the Hashcat HIP Backend seems to need it

you can try to downgrade your llvm to a version where the falg legacy-pass-manager ist still available or you have to wait for hashcat to support the new pass-manager

Ok.
I found a solution. It seems that there is something wrong with HID.
I tried to use -D 2 option to change my device. With -d 2 it worked.
