Hi all,
This is just updating the last commit on which that Matthew requested
a couple of changes. Otherwise all reviewed.
Thanks a lot,
Lionel Landwerlin (4):
drm/i915/perf: update generated files headers
drm/i915/perf: remove redundant oa buffer initialization
drm/i915/perf: pass stream

We initialize the OA buffer everytime we enable the OA unit (first call in
gen[78]_oa_enable), so we don't need to initialize when preparing the metric
set.

Hi all,
Chris recommended we stick on what the HW can do with regard to the
buffer size parameter. This is reflected in the update of patch 4.
Added patch 1 which was requested for newer test config files by
Lucas. I figured we could update the existing files too.
Cheers,

trying to guess what the
user wanted and selected the smallest buffer size, but in the end an
actual size parameter is better, giving userspace more flexibility and
removing guesses from i915.

We would like to make use of perf in Vulkan. The Vulkan API is much
lower level than OpenGL, with applications directly exposed to the
concept of command buffers (pretty much equivalent to our batch

Here we introduce a mechanism by which the execbuf part of the i915
driver will be able to request that a batch buffer containing the
programming for a particular OA config be created.
We'll execute
making the execbuf with this flag to
also own the perf fd at the time of execbuf.

executed with a given OA configuration.
This mechanism essentially allows the userspace driver to go through
several OA configuration without having to open/close the i915/perf
stream.

s are in no way final, in particular the execbuf uapi
changes is probably unworkable in production (it was just a quick way
to prove things are working). I heard discussions about execbuf3, this
could probably be tied into that.
Looking forward to your comments.
Thanks,
