I was using a relative path and starting in the top of the kernel tree, so: $ cd kernel $ mkdir ../perf $ make -s -C tools/perf JOBS=24 O=../perf put everything in toos/perf (no suprise really) I will change my script to use an absolute path (which I checked does work fine). Sorry for the noise. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
