drm/etnaviv: replace license text with SPDX tags

2018-05-18T13:27:56+00:00

This replaces the repetitive GPL-2.0 license text in code and header files
with the SPDX tags. Generated hardware headers aren't changed, as any changes
there need to be done in the upstream rnndb repository.

drm/etnaviv: use submit exec_state for perfmon sampling

2018-01-02T16:33:01+00:00

The GPU exec state may have changed at the time when the perfmon sampling
is done, as it reflects the state of the last submission, not the current
GPU execution state.

So for proper sampling we must use the submit exec_state.

drm/etnaviv: add infrastructure to query perf counter

2017-10-10T09:45:41+00:00

Make it possible that userspace can query all performance domains and
its signals. This information is needed to sample those signals via
submit ioctl.

At the moment no performance domain is available.

Changes from v1 -> v2:
- use a 16 bit value for signals
- fix padding issues
- add id member to domain and signal struct

Changes v4 -> v5
- provide for each pipe an own set of pm domains
