It's a shame that the amazing progress made in Exynos5 Chromebook upstreaming support - where it works with barely a handful of patches on top of current mainline - is disregarded by people who try a three-year old vendor tree and conclude the whole ecosystem is broken and in need of a messiah.

Looking forward to full atomic modesetting support in 3.21, but still having mainline run virtually out of the box on actual bulk consumer devices is fantastic, and such a refreshing change from a few years ago.

You shouldn't have to battle random vendor trees to run Linux on your device, you shouldn't have to pay a consultancy like us to fight those random vendor trees to ship a device, and anyone who suggests this is a good idea has learned nothing from the past few years.

Many thanks to those who do the quiet, unappreciated work to push this forward and make sure it continues working - including the fantastic kernelci.org.

Great atomic progress, including by our own Gustavo Padovan - with more Exynos atomic queued for 3.21.
 
Great post by @danvet about Linux 3.20, atomic mode setting and drm: http://bit.ly/1J1MW6n
Linux 3.19 was just released and my usual overview of what the next merge window will bring is more than overdue. The big thing overall is certainly all the work around atomic display updates, but read on for what else all ha...

Any chance android will adopt this solution instead of their ADF ?

An overview of the ARMv8.1 architecture extensions (enhancements over current ARMv8). An important feature is the possibility to run a host OS kernel directly in EL2 (Hypervisor mode) saving some extra context switches for KVM. But there are other interesting features, so enjoy the article (though I would say pretty high level at this stage).
ARMv8-A, the ARMv8 A-profile version of the ARM architecture, was first publically previewed in October 2011. Over the past two years, there have been a growing number of ARMv8-A announcements from ARM, such as its Cortex-A53 and Cortex-A57 products, plus additional cores and end-user devices ...

My first introduction to Maniac Mansion was the bit in Day of the Tentacle where you could play that as a sub-game ... amazing.
 
Sweet!
25 years ago, Ron Gilbert and Gary Winnick designed Maniac Mansion, one of the defining titles from the golden era of adventure games. Now they're making a spiritual successor. The two creators...

For the sake of posterity: That thing on the picture is a storage medium - hence the omnipresent icon for save action. :D

And to think the US forces the use of a fixed digit numbering plan whereas other countries use flexible digit counts. Perhaps Bruce needs a better analogy

We've sold over five million Pis! The photo shows the first batch ever made, a pallet load of 2000; we've come a long way. And none of it would have happened without you, our community. Thank you - we'd be nowhere without you.

#raspberrypi
Yesterday we received some figures which confirmed something we've suspected for a few weeks now: we've sold over five million Raspberry Pis. The Pi has gone from absolutely nothing just under three years ago, to becoming the fastest-selling British computer. (We still have Sir Alan Sugar to ...

A really useful tool, but just the start of a long debugging/profiling journey.
 
+Pekka Paalanen just posted a very good article about reducing the latency between the moment an application requests a repaint and when it actually reaches the screen.

To support this work and better debug bad behavior, he developed a tool called Wesgr that displays the log files exported by Weston and outputs a nice graph in svg or png.

Kudos for his work!

Great stuff, and glad the (sometimes painful) work to implement strict isolation at all levels of the Wayland protocol hasn't gone to waste.
 
Got a fully sandboxed game running under xdg-app in a wayland session!
Its not a secret that I've been working on sandboxed desktop applications recently. In fact, I recently gave a talk at devconf.cz about it. However, up until now I've mainly been focusing on the bundling and deployment aspects of the problem. I've been running applications in their own ...

Fixed in Wayland, obviously ;)
 
Having a maximum keycode of 255 is a long-standing problem with X, surprisingly there was no writeup of why it is a problem. Well, here is one now:

http://who-t.blogspot.com.au/2014/12/why-255-keycode-limit-in-x-is-real.html
A long-standing and unfixable problem in X is that we cannot send a number of keys to clients because their keycode is too high. This doesn't affect any of the normal keys for typing, but a lot of multimedia keys, especially ...

A couple weeks ago, qualcomm (quic) surprised some by sending kernel patches to enable the new adreno 4xx family of GPUs found in their latest SoCs.  Such as the apq8084 powering my ifc6540 board with the a420 GPU.  Note that...
