Any idea how long its been broken? Sorry, not yet. I haven't yet looked into where/how it's broken that would narrow that down... The other thing to bear in mind is that the userspace tools have not seen any MIPS additions since 2010, the last commit being to add 1004K and 34K support: https://sourceforge.net/p/oprofile/oprofile/ci/master/tree/events/mips/ Though I'm not sure if anyone is maintaining a vendor specific fork containing further support. > > I'll let it sit on the list for a bit in case anybody does object and > wants to fix it instead.
