  • Per-Window Flipping In Present With XWayland Support Revised

    While the belated X.Org Server 1.20 is onto the release candidate stage, there still are some feature patches expected to land and among them is the per-window flipping support in the Present extension with support wired through for XWayland.

    Worked on last summer via GSoC 2017 was this support by Roman Gilg with a goal of reducing tearing in XWayland windowed environments by adding per-window page-flipping support to Present and wiring that up to XWayland so those X11 apps atop Wayland wouldn't be bound to using just one buffer.

  • Airlie Moves Ahead With His Plan For Soft FP64 For Mesa, OpenGL 4.3 For Evergreen GPUs

    Yesterday we wrote about David Airlie working on a fresh push to get "soft FP64" support in Mesa for allowing some older graphics cards on the R600g driver to then have OpenGL 4 support thanks to this double-precision floating-point support being their last blocker. That code is moving forward.

    The soft FP64 support within GLSL shaders is the work originally done by former GSoC contributor Elie Tournier. Airlie is preparing to merge that code along with various changes he has made since then, including the option for Gallium3D drivers to individually decide about opting in or not to this emulated FP64 support.

  • Mesa Developers Working To Figure Out How To Improve Their Release Process

    Following the very bumpy Mesa 17.3 releases, Mesa developers are currently discussing ideas for improving the release process moving forward.

    Mesa 17.3 was shipping with some nasty bugs that went uncaught among other issues leading some to feel that the 17.3 series has been their worst release in recent memory. But the good news is that's been igniting the discussion the past week about how to turn this situation around.

Endless OS Version 3.3.13

Improved Chromium behaviour with low memory. The Chromium browser now frees up the memory used by other tabs much more effectively when you’re running very low on memory. This means you have to wait a little longer after you switch to one of these tabs, but keeps the system running more smoothly and helps to prevent crashes. Read more

Ubuntu 18.10 Will Boot Faster, Thanks to LZ4 Initramfs Compression

Canonical's Balint Reczey recently proposed the implementation of LZ4 compression to Ubuntu's initramfs (initial ramdisk) instead of the older gzip compression used in previous releases of the wildly used operating system. LZ4 is a lossless data compression algorithm that offers extremely fast compression and decompression speed. During some initial tests on an old laptop, the developer reports that the initramfs extraction time decreased from approximately 1.2 seconds to about 0.24 seconds. The creation of the initramfs also received a speed boost of 2-3 seconds, decreasing from roughly 24 seconds to about 21 seconds, despite of slightly bigger initramfs files. Read more

Fresh Benchmarks Of CentOS 7 On Xeon & EPYC With/Without KPTI/Retpolines

While every few weeks or so we have ended up running benchmarks of the latest Linux Git kernel to see the evolving performance impact of KPTI (Kernel Page Table Isolation) and Retpolines for Meltdown and Spectre V2 mitigation, respectively, a request came in last week from a premium supporter to see some new comparison test runs on CentOS 7 with its older 3.10-evolved kernel.

Reviewing logins on Linux

The last command provides an easy way to review recent logins on a Linux system. It also has some useful options –- such as looking for logins for one particular user or looking for logins in an older wtmp file. The last command with no arguments will easily show you all recent logins. It pulls the information from the current wtmp (/var/log/wtmp) file and shows the logins in reverse sequential order (newest first). Read more
