Subject: [PATCH v3 0/4] drm/panfrost: Expose perf counters to userspace
Date: Wed, 29 May 2019 11:52:29 +0200	[thread overview]
Message-ID: <20190529095233.26277-1-boris.brezillon@collabora.com> (raw)

Hello,

This a new version of the panfrost perfcnt series, this time exposing
this functionality through 2 ioctls instead of the debugfs approach
used in v2.

I also went for Emil's suggestion to expose those ioctls only when
the unstable_iocts unsafe param is set to true. This way, I hope we'll
be able to deprecate those ioctls when the generic solution to expose
global perf counters is out.

Also addressed the problems reported by Rob and Steven.

Regards,

Boris

Changes in v3:
* Expose things through ioctls instead of debugfs (needed for
  per-FD address space that is being worked on by Rob)

Changes in v2:
* Complete rewrite to expose things through debugfs

Boris Brezillon (4):
  drm/panfrost: Move gpu_{write,read}() macros to panfrost_regs.h
  drm/panfrost: Add a module parameter to expose unstable ioctls
  drm/panfrost: Add an helper to check the GPU generation
  drm/panfrost: Expose performance counters through unstable ioctls
