Mainline Kernel on Tegra K1 (Acer Chromebook 13 CB5-311)

[tincman]

4.7 turned out to be a bust as well with the same wifi/sdhci errors.

However, 4.8-rc1 seems to be working! Wifi is stable and working well.

Also, 4.8-rc1 has some tegra-dmaengine work and that seems to have fixed the APD/EMEM errors when using USB with LPAE!

I have not tried USB3/XUSB yet, but it's supposed to be enabled.

My EMMC speed dropped to non-UHS speed, even though some of the 4.8-rc1 commits were related to re-implementing it...

There seems to have been a lot of tegra related commits this round as well, and I haven't gotten through most of them yet, but this definitely seems a good kernel for us!

A solution for kwin on wayland?
$this->bbcode_second_pass_quote('', 'S')upport for render devices

Our virtual rendering platform in KWin/Wayland gained a new feature. Like the normal DRM device it now uses udev to find all possible devices and will default to a render device (e.g. /dev/dri/renderD128) if present. If not present it will look for a card device created through the vgem driver. This is a change intended mostly for the use on build.kde.org so that we can properly test OpenGL compositing, but is also a handy feature for running KWin in the cloud on systems with “real” GPUs. If no GPU is present one can easily make KWin pick the virtual device.

Probably half of one? Judging from the description, it's equivalent to "off-screen" rendering (does the rendering, but does not display it).

My guess is this would make it much easier to patch to do the equivalent with Gnurou's xserver/westonr patches, but still would need a hack to manually set buffer formats and open the control node for display (which gnurou hardcodes in his patches), so nothing upstreamable.

On a different note, I'm having trouble with the AC adapter not working again (bq24735-charger). My patches should still be working and I haven't been able to figure out what exactly is going wrong.

[haagch]

Yea, I asked him and he said
$this->bbcode_second_pass_quote('', 'U')nfortunately not. Render device support is only available in the virtual rendering platform.

Hi!, Im planning on buying this chromebook. However, i can only buy the Acer C810, that seems to be an education variant.
I cant see specifications differences, but maybe a education variant could be more locked down? Have someone tried to install ALARM on this model?

Thanks

I tried to install arch by editing the script mentioned in second post and installing it. Installation runs flawless but i'm unable to get nouveau running. My Laptop boots fine but hangs at loading lightdm (black screen with white command-dot ( _ )), no tty, have to reboot here. Here r my specs:

Kernel: 4.8-rc6
Nouveau: provided by Kernelpackage
Xserver: build from tincman's PKGBUILD (but i've also tested unpachted)

There is! Xorg-server 1.18.4 introduced present extensions to the mode setting driver that I haven't figured out how to merge with the tegra hacks from gnurou.

For the time being, 1.18.3 should still work: https://github.com/sctincman/PKGBUILDs/ ... org-server

nope doesn't work for me
