* perf: restrict libunwind dependency to archs that actually support libunwindMatthias Schiffer2018-02-251-1/+1
| | | | | | | | | | Allow building perf on uncommon targets again. Depending on the kernel version, not all of these archs will actually use libunwind in perf. Still, it seems simpler and less error-prone to use the same list that is defined in the libunwind package. Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
* perf: use libunwindMaxim Gorbachyov2018-01-271-1/+1
| | | | | | | Without libunwind perf does not show userspace stack frames. Tested on mvebu. Signed-off-by: Maxim Gorbachyov <maxim.gorbachyov@gmail.com>
* perf: Depend on KERNEL_PERF_EVENTSFlorian Fainelli2017-06-051-1/+1
| | | | | | | | | | | | | | | | | | | | The kernel needs to have PERF_EVENTS built otherwise we will run into the following: root@(none):/# perf top perf_event_open(..., PERF_FLAG_FD_CLOEXEC) failed with unexpected error 89 (Function not implemented) perf_event_open(..., 0) failed unexpectedly with error 89 (Function not implemented) Error: The sys_perf_event_open() syscall returned with 89 (Function not implemented) for event (cycles). /bin/dmesg may provide additional information. No CONFIG_PERF_EVENTS=y kernel support configured? Make sure this functional dependency is captured. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>
* perf: Disable perf for ARC770 only, enable for ARC HS38Alexey Brodkin2017-05-111-1/+1
| | | | | | | | | | | | | | | Toolchain built for ARCv1 (read for ARC700 cores) by default has disabled atomic ops (-mno-atomic). When we build Linux kernel for ARC770 which has LL/SC instructions and thus may handle normally atomic ops we explicitly add "-matomic" in CFLAGS. But since user-space perf utility has no way to extract CPU config options from Kconfig/defconfig it uses compiler default settings. In case of ARCv2 (read ARC HS38) atomics are enabled by default and so perf builds perfectly fine thus reenabling perf for ARC HS38 (actually for non-ARC700 targets).
