Hi, sorry you are having problems with this. What type of server/machine are you running on? If you don't care about using Caladan's memory bandwidth controller, you can just disable it by using this command: 'sudo ./iokerneld ias nobw'
It's just a physical server (not a virtual instance like AWS). It works fine when using the nobw option, but I'd like to try out the memory controller feature, is there any workaround? I separately installed pcm on my server and ran pcm-memory and it worked fine, so I don't think it's a hardware issue.
In your clean build, PCM may be using a different interface to access the performance counters. We need to directly access the PCI configuration space using /dev/mem to read the counters. What is the model of your server?
my server model is : 30BES2C300 (Manufacturer: [Lenovo] (https://www.lenovo.com/)) and this is information about my server:
Hello, I'm having a problem running your code.
This is my server information:
Hardware

Ubuntu 18.04 with kernel 5.2

When I run the sudo ./iokerneld ias command, I get the following message:
Why am I getting the following error even though I am already running as root? My server is using a Xeon cpu, so I don't think there is a hardware issue.
