Let me prefix this with "I don't know what I'm doing" > Does it not work with GLIBC any more or why do you make it depend on > musl only now? Does this work with uclibc-ng? I suspect it'll break spectacularly with glibc. I'm sure the patches could be modified to have both glibc & musl compatibility but it's beyond my wit to know how. I was interested in getting perf to work (without enabling broken packages) under Archer C7 v2 which uses musl now by default. I've no idea about uclibc-ng. > > I assume that this will not work on kernel 3.18 and kernel 4.3, which is > fine, as you haven't added patches for these kernel versions, but the > dependency is missing. Please add @!LINUX_3_18 @!LINUX_4_3 Now that's something I can do....if it's worth the bother bearing in mind other comments? > > Will this be in kernel 4.5? No idea. My Archer (ar71xx) isn't on 4.4 yet let alone 4.5 A few people have put effort into getting perf running on the above mentioned platforms, I thought it worth throwing at OpenWrt devel list as a patch to pass the effort on and see what sticks :-) If it doesn't stick then fair enough.
