Testing For The Latest Linux Kernel Power Regression

Filed under
Graphics/Benchmarks

Frame-buffer compression (FBC) support was disabled by default in the Linux 3.15 stable series for Haswell hardware and newer since the support wasn't mature and there were Intel HD Graphics users reporting issues with this feature being turned on, so it was disabled by default and hidden behind a kernel module parameter. After an Arch Linux user experienced a 4+ Watt increase in power draw for his Apple laptop, he bisected it to this FBC feature, but Intel Linux developers weren't expecting FBC to make such a huge difference in power draw. The matter is still being investigated but FBC simply can't be flipped back on by default since the code is incomplete and there's still some unmerged patches under review that won't make it until at least the Linux 3.18 kernel.

FSF's High Priority Project List Now Has A Committee

The Free Software Foundation has now built up a committee to review their "High Priority Projects" list and they're looking for more feedback from the community. Nearly ten years ago is when the Free Software Foundation began listing what they viewed as the High Priority Free Software Projects in a list. This list has over time contained some definite high-priority projects related to freeing Java and Adobe PDF support and open graphics drivers to some more obscure projects of high priority like a free version of Oracle Forms, a replacement to OpenDWG libraries for CAD files, automatic transcription software, etc. I've personally called out many of the FSF HPP for what they're worth with my thoughts over the years.
