Bug Description

== Comment: #0 - Frederic Barrat - 2016-08-10 09:28:02 ==
---Problem Description---
In the cxl driver, the psl_fir_cntl register is set to the recommended value for a lab environment. This should be converted to use the recommended setting for a production environment.

Contact Information = <email address hidden>

---uname output---
Linux freak 4.4.0-34-generic #53-Ubuntu SMP Wed Jul 27 16:04:07 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux

---Additional Hardware Info---
CAPI fpga card

Machine Type = any

---Steps to Reproduce---
 setting of the psl_fir_cntl can be accessed through
# cat /sys/kernel/debug/cxl/card0/fir_cntl

Fix is in powerpc maintainer's tree and will find its way in 4.8-rc2;

cxl: Set psl_fir_cntl to production environment value
https://git.kernel.org/powerpc/c/c6d2ee09c2fffd3efdd31be2b2

However, though simple, the upstream patch won't apply cleanly to the Xenial tree due to other patches merged in 4.8. So I'm attaching a version of the patch which applies on Xenial

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
