If an event on a particular processor revision is broken or unusable it can be excluded from the list of events with a corrected list of events. There certainly have been errata listing events that do not work on specific revisions of armv8 processor implementations. >>> >> >> Then there are vendors who do not always properly implemenent MIDR or IIDRs (people who live in glass houses...). >> >> Btw, topic originally discussed here: >> https://lkml.org/lkml/2017/5/2/113 >> >> Thanks, >> John >> >>> -Will > > Hi John, > > Attached is a patch that leaves the MIDR value unmodified and uses regular expressions in the mapfile.csv instead to ignore those bits. I have verified that the changes work on ARM Cortex a53 processor. Does it look reasonable? > Hi Will, This looks ok. Personally I find the regular expression in the cpuid slightly difficult to read. I mean, for example, for the revision digit we are using a 12-char regular expression in place, which warps the cpuid string length. BTW, can you also update the pmu events README to mention that posix regular expressions in the CPUID are acceptable?
