Comment 17 for bug 1688158

Jeff,

Could someone from QTI please help test
http://launchpad.net/bugs/1688158 zesty-proposed kernel for SMMU
passthough? We won't have an NVME drive (yet) installed in time for
this SRU verification. I have boot tested this kernel and it boots fine
on the QDF2400.

To enable proposed add the following line to your /etc/apt/sources.list

deb http://us.ports.ubuntu.com/ubuntu-ports/ zesty-proposed main
restricted

Then install the kernel and fio tool.
$ sudo apt update

$ sudo apt install linux-image-4.10.0-23-generic
linux-image-extra-4.10.0-23-generic

$ sudo apt install fio

For kernel parameter cases 0/1 run the tests.
iommu.passthough=0/1

$ sudo fio --name=global --readonly --group_reporting --direct=1
--ioengine=libaio --rw=read --eta-newline=1s --size=1T --blocksize=512k
--iodepth=32 --numjobs=1 --runtime=10s --name=nvme_0
--filename=/dev/nvme0n1

After you are done posting the results to the bug. Please update the
tag "verification-needed-zesty" to "verification-done-zesty"

Thanks
Manoj Iyer
