Subject: [PATCH 0/3] perf: Add Arm Network-on-Chip PMU driver
Hi all,
Somewhat later than hoped (sorry!), now that it's finally had the chance
for enough testing to flush out all the silly bugs, here's the NI-700
driver I've had kicking around in various forms for the last 18 months.
I squashed in NI-710AE support since that appeared in the meantime and
the differences are minimal, however I have not felt compelled to go
back and genericise all the original NI-700 references. I don't think
I'm giving too much away to say that there will be further new product
support to add in future, so I will be back with more soon enough.
Note that the driver patch depends on the the cpumask_any_and_but()
addition queued in arm64/for-next/perf.
Thanks,
Robin.
