add preliminary aarch64 (arm64) support
|
|
|
c7ea89 |
|
|
|
c7ea89 |
There has been some work to build fedora 19 on 64-bit arm armv8 machines
|
|
|
c7ea89 |
(aarch64). I took a look that the why the papi build was failing. The
|
|
|
c7ea89 |
attached is a set of minimal patches to get papi to build. The patch is
|
|
|
c7ea89 |
just a step toward getting aarch64 support for papi. Things are not all
|
|
|
c7ea89 |
there for papi to work in that environment. Still need libpfm to
|
|
|
c7ea89 |
support aarch64 and papi_events.csv describing mappings to machine
|
|
|
c7ea89 |
specific events.

Add aarch64 Cortex A57 presets
|
|
|
c7ea89 |
|
|
|
c7ea89 |
The events for the ARM Cortex A57 events look to be the same as the
|
|
|
c7ea89 |
events for the ARM Cortex A15 events. Add an entry so the preset are
|
|
|
c7ea89 |
available for the ARM Cortex A57.
