SBI PMU Extension Support in Linux Kernel


Dan Mangum
 

Hey folks,

I have been following along with the addition of the addition of the Performance Monitoring Unit Extension that was added to SBI in v0.3. I noticed that it has not been implemented in the RISC-V Linux kernel upstream yet and I was wondering if there was an ongoing effort to do so? If there is opportunity for contributing to that effort I would love to get involved. If I am looking in the wrong places for where this would be implemented, or if there are references where I could answer my own questions please feel free to redirect me to those sources and I will happily dive in.

Thanks!
Dan

Would recommend joining the linux-riscv@ list if you want to get involved with the kernel
