From 1234471e2d11e4ee47f6de452dd8b8aeb09b45de Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Tue, 23 Oct 2012 22:44:49 +0900 Subject: perf header: Fix numa topology printing Andrew reported that the commit 7e94cfcc9d20 ("perf header: Use pre- processed session env when printing") regresses the header output. It was because of a missed string pointer calculation in the loop.

The strbuf_addf() was checking buffer length with a result of vscnprintf() which cannot be greater than that of strbuf_avail(). Since numa topology and pmu mapping info in header were converted to use strbuf, it sometimes caused uninteresting behaviors with the broken strbuf. Fix it by using vsnprintf() which returns desired output string length regardless of the available buffer size and grow the buffer if needed.

Note that -Iarch/foo/include/uapi is present _before_ -Iarch/foo/include. This makes sure we get the userspace version of the pt_regs struct. Ideally, we wouldn't have the latter -I flag at all, but unfortunately we want asm/svm.h and asm/vmx.h in builtin-kvm.c and these aren't part of the UAPI - at least not for x86. I wonder if the bits outside of the __KERNEL__ guards *should* be transferred there. I note also that perf seems to do its dependency handling manually by listing all the header files it might want to use in LIB_H in the Makefile. Can this be changed to use -MD? Note that to do make this work, we need to export and UAPI disintegrate linux/hw_breakpoint.h, which I think should've been exported previously so that perf can access the bits. We have to do this in the same patch to maintain bisectability.
