From d819e7fa76e2b732aa7c33ab0e9a834781090824 Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Thu, 18 Oct 2018 06:28:44 -0700 Subject: perf: fix do_compile failure with /tmp mounted with noexec On a builder which has /tmp mounted nexec, the ARM64 generation of the sycall table will fail: [snip] |perf-1.0/tools/perf/arch/arm64/entry/syscalls//mksyscalltbl: /tmp/create-table-6VGPSt: Permission denied [snip] To avoid the permission denied error, we must instruct the perf build to place temporary files in an appropriate directory (versus always using /tmp). To do this, we need both a kernel source change to perf, and a recipe change to pass the temp directory in by a TMPDIR variable. The linux-yocto has a reference kernel change: [perf arm64: Fix generate system call table failed with /tmp mounted with noexec], that has also been submitted upstream mailing list linux-perf-users@vger.kernel.org Signed-off-by: Hongxu Jia Reviewed-by: Bruce Ashfield Signed-off-by: Richard Purdie --- meta/recipes-kernel/perf/perf.bb | 1 + 1 file changed, 1 insertion(+) diff --git a/meta/recipes-kernel/perf/perf.bb b/meta/recipes-kernel/perf/perf.bb index 586422f769..af099043e1 100644 --- a/meta/recipes-kernel/perf/perf.bb +++ b/meta/recipes-kernel/perf/perf.bb @@ -75,6 +75,7 @@ EXTRA_OEMAKE = '\ perfexecdir=${libexecdir} \ NO_GTK2=1 \ ${PACKAGECONFIG_CONFARGS} \ + TMPDIR="${B}" \ ' EXTRA_OEMAKE += "\ -- cgit 1.2.3-korg
