Bug description:
[Impact]
The IBM GenWQE Accelerator Adapter does not work correctly in the latest 3.16 kernel.
[Test Case]
1) Create a guest system on PowerKVM using image disk file, install from virutal SCSI DVD. Especially assign the GenWQE card via PCI passthrough.
2) Start up the guest
3) lspci -knd :044b
3) dmesg|grep genwqe
4) ) modprobe genwqe_card.ko
No module is assigned to the card
5) ls -l /dev/genwq* shows no file at all.
One device file would be expected here.
[Fix]

---Problem Description---
In our opinion the 2.0.15 version of the IBM GenWQE Accelerator Adapter driver part of Ubuntu 15.04 is not working. A higher version would be needed. The driver is part of the linux-image-extra-3.16.0-24-generic package.

---uname output---
Linux tulg3 3.16.0-24-generic #32-Ubuntu SMP Tue Oct 28 13:06:19 UTC 2014 ppc64le ppc64le ppc64le GNU/Linux
---Additional Hardware Info---
0001:00:02.0 Processing accelerators: IBM GenWQE Accelerator Adapter
Class: 1200 VendorID: 1014 DeviceId: 044b assigned to the PowerKVM guest via PCI passthrough (vfio-pci)
Machine Type = 8284-22A PowerKVM
---Debugger---
A debugger is not configured
---Steps to Reproduce---
1) Create a guest system on PowerKVM using image disk file, install from virutal SCSI DVD. Especially assign the GenWQE card via PCI passthrough.
2) Start up the guest
3) lspci -knd :044b
3) dmesg|grep genwqe
4) ) modprobe genwqe_card.ko
No module is assigned to the card
5) ls -l /dev/genwq* shows no file at all.
One device file would be expected here.
Stack trace output:
no
Oops output:
no
System Dump Info:
The system is not configured to capture a system dump.

Christian and I tried out CVS version of the driver and that works. Ubuntu picked and unfortunate intermediate version of the driver which had broken irq registration. This was fixed later by Sebastian Ott and Kleber and I added on top of that some more patches which did cleanups and more importantly added System p specific recovery features e.g. like EEH handlers and a method to reload the bitstream for p.
Therefore it would be great if someone could have the Ubuntu folks
pickup the latest version from Kernel.org.
I know that Greg KH has a good version of the code in his tree. We
need to check if that has made it yet into Linux version (both should
be the same).

Christian has checked the linux.git version of the genwqe_card driver compiled against his Ubuntu kernel and found it working.
SHA is 206c5f60a3d902bc4b56dab2de3e88de5eb06108.
Patched affecting the driver are usually prefixed with GenWQE or genwqe
7276883f1f98cd0a92fdc049f69bdc0912f7fc16 misc/GenWQE: fix pci_enable_msi usage
was the one which fixed the problem introduced by
a30d0108b09ae46d24594a2e699c4dad21bb4af4 Use pci_enable_msi_exact() instead of pci_enable_msi_block()
So please have a look how we convince the Ubuntu folks to update their
version of the code. Thanks.

Confirm that version 2.0.25 built against the mainline kernel is working for us.
Used given SHA based on Linux 3.18-rc4, paid attention to the new genwqe_card.h file.
To make matters worse the picked 2.0.15 version leads to system hung soon after the dmesg messages described above (i.e. when the genwqe_card module is loaded).
Thus raising priority to P2 normal.
Hope Franks and my comments answer 'more info'. Setting state back to
open.
