Title:
  PSL data cache should be flushed before resetting CAPI adapter

  ---Problem Description---
  The PSL data cache should be flushed before resetting a CAPI adapter.
  If the PSL data cache holds dirty cache line when it is reset, the host 
trying to access that memory when the link is down may face a Uncorrectable 
Error (UE), forcing a reboot of the system.

ppc64le ppc64le ppc64le GNU/Linux
   
  ---Additional Hardware Info---
  CAPI adapter needed + AFU image using the PSL cache (e.g. afu_directed 
memcpy) 

   
  Machine Type = Tuleta 

  ---Steps to Reproduce---
   There's some randomness to it, but triggering a memcpy test + card reset in 
a loop can produce it:

  memcpy_afu_ctx -p100 -l1000
  echo 1 > /sys/class/cxl/card0/reset
  Fix is already upstream under commit ID:
  aaa2245ed836824f21f8e42e0ab63b1637d1cb20 
  "cxl: Flush PSL cache before resetting the adapter"

  We would like the fix released for both 16.04 and 16.10 please.

[Kernel-packages] [Bug 1632049] Re: PSL data cache should be flushed before resetting CAPI adapter

[Seth Forshee]

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-
yakkety' to 'verification-done-yakkety'.

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!

  Machine Type = Tuleta 

  ---Steps to Reproduce---
   There's some randomness to it, but triggering a memcpy test + card reset in 
a loop can produce it:

  memcpy_afu_ctx -p100 -l1000
  echo 1 > /sys/class/cxl/card0/reset
  Fix is already upstream under commit ID:
  aaa2245ed836824f21f8e42e0ab63b1637d1cb20 
  "cxl: Flush PSL cache before resetting the adapter"

  We would like the fix released for both 16.04 and 16.10 please.

  PSL data cache should be flushed before resetting CAPI adapter

Bug description:
  ---Problem Description---
  The PSL data cache should be flushed before resetting a CAPI adapter.
  If the PSL data cache holds dirty cache line when it is reset, the host 
trying to access that memory when the link is down may face a Uncorrectable 
Error (UE), forcing a reboot of the system.
   
  ---uname output---
  Linux freak 4.4.0-38-generic #57-Ubuntu SMP Tue Sep 6 15:40:06 UTC 2016 
ppc64le ppc64le ppc64le GNU/Linux
   
  ---Additional Hardware Info---
  CAPI adapter needed + AFU image using the PSL cache (e.g. afu_directed 
memcpy) 

   
  Machine Type = Tuleta

  memcpy_afu_ctx -p100 -l1000
