[Intel-gfx] [PATCH v4 0/3] Add support for loadable OA configs

[Lionel Landwerlin]

Hi all,

Here is a v4 of this series. It is mostly prompted by one of Imre's
series [1] that attracted my attention at how we do locking in the
perf part of the driver.

I believe up to now it was fine due to the fact that we had all
configs always present in kernel space. With this series, configs can
now go away. So locking needs some reworking, in particular
dev_priv->perf.exclusive_stream needs to be locked. This series also
introduce a new lock for adding/modifying/removing configs.

Cheers,
