[Maq]

Hello.

I try to install amduprof-5.0-1479.x86_64 on RHEL 8.10.

I use rpm wirh rpm -ivh amduprof-5.0-1479.x86_64.rpm. And after i start yum install bcc.

BCC and uprof are intall on 4 servers and i can start /usr/share/bcc/tools/execsnoop.

But only one is compliance with BCC. The 3 others not.
