Subject: [PATCH v5 0/4] perf: AARCH64 arch support
Date: Wed, 22 Jan 2014 15:11:15 +0100 [thread overview]
Message-ID: <1390399879-5109-1-git-send-email-jean.pihet@linaro.org> (raw)
Add AARCH64 specific support. This includes the following:
- AARCH64 perf registers definition and hooks,
- compat mode registers use, i.e. profiling a 32-bit binary on
a 64-bit system,
- unwinding using the dwarf information from the .debug_frame
section of the ELF binary,
- unwinding using the frame pointer information; in 64-bit and
compat modes.
Note: support for unwinding using the dwarf information in compat
mode requires some changes to the libunwind code. Those changes
have been submitted on the libunwind ML and are in discussion.
Tested on ARMv7, ARMv8 and x86_64 platforms. The compat mode has been
tested on ARMv8 using statically built 32-bit binaries.
