Hello, It's my understanding that the changes for DMC and L3C events have been merged to the mainline kernel and that the CCPI2 changes are our for review. I've reminded my management that papi/libpfm4 will need an update. This should be on the workplan soon.
Is the official source for libpfm4 still over on bitbucket?
