Novena laptop board, PVT-1 board rev - dmesg, kernel config from rough Debian build

[Martin Langhoff]

Got my hands on a Novena Laptop board, which currently boots to a
cosmetically rough Debian build. It is, however, pretty functional - HDMI,
2x ether, WLAN work, audio looks like it works.

Interesting files from a fully booted system:
http://dev.laptop.org/~martin/novena-pvt1/

I'll be hunting tonight for the kernel patches / kernel git repo. This is a
quickie lunchtime break email ;-)

Hi Peter, list,

The dts file for the patched 3.13-rc4 that comes in the base image is right
now at
https://github.com/xobs/novena-linux/blob/3.13.0-rc4%2B/arch/arm/boot/dts....

The branch (here:
https://github.com/xobs/novena-linux/commits/3.13.0-rc4%2B) shows that
there's a bunch of patches on top of 3.13-rc4. Some are board
quirks (all/most commits from xobs(a)kosagi.com), some are patch series from
Russel King and others that seem to be meant to be upstreamed.

There's what appears to be a rebase of the same work, with less patches,
against 3.14-rc2. Looks like some of the upstream patch series landed in
3.14-rc2.

What's current "universal" kernel rev on the fedora arm builds right now?
What are the policies re patches with board quirks? I'll be happy to help
prep this into the arm kernel rpm, if it's acceptable, or to build a custom
kernel rpm with the appropriate patches.

I'm just a tad out of date with current state of 'universal/dts' kernels in
fedora-arm.

cheers,



m

Russell has been working a lot on the cubox-i and in particular HDMI
support, last I looked he had a series of 35+ patches that should be
headed for 3.15.

There's been a lot of i.MX6 stuff land upstream over the last 3-4
kernels, it's improving rapidly.

So everything regard quirks should be going via a dts file for imx6
these days and then any driver changes to support the device. I
strongly suspect a dts will be enough to get you booting to a serial
console with sata/mmc/network/usb etc which is the state of most imx6
devices such as the wandboard at the moment.

Out side of that I noticed there's a non upstreamed sound and codec
driver but it looks like its under active review so I suspect that's
not far away. Assuming Russell's HDMI patchset land in 3.15 (and we're
all hoping for that for wandboard/cubox/utilite too) I personally
don't believe we'll need much else to make it mostly work well. EG
cubox-i just worked first time without any tweaks needed at all :-)
