  • How the 60-evdev.hwdb works

    libinput made a design decision early on to use physical reference points wherever possible. So your virtual buttons are X mm high/across, the pointer movement is calculated in mm, etc. Unfortunately this exposed us to a large range of devices that don't bother to provide that information or just give us the wrong information to begin with. Patching the kernel for every device is not feasible so in 2015 the 60-evdev.hwdb was born and it has seen steady updates since. Plenty a libinput bug was fixed by just correcting the device's axis ranges or resolution. To take the magic out of the 60-evdev.hwdb, here's a blog post for your perusal, appreciation or, failing that, shaking a fist at. Note that the below is caller-agnostic, it doesn't matter what userspace stack you use to process your input events.

  • Mesa 18.2-RC2 Released With 17 Fixes So Far

    One week after branching Mesa 18.2 and issuing the first release candidate, the second weekly RC is now available for testing.

    Mesa 18.2-RC2 has 17 patches queued, including several V3D (formerly "VC5") Broadcom driver fixes, build system updates, fixing the DRISW compilation for Android Nougat, and other small fixes.

  • Mesa 18.2.0-rc2

    The second release candidate for the Mesa 18.2.0 is now available.

  • AMDGPU LRU Bulk Move Functionality Increases Performance In OpenCL And Vulkan
  • AMD Releases 18.Q3 Linux Drivers for Radeon Pro, Including Ubuntu 18.04 LTS Support

    This update also brings Vulkan 1.1 support, and initial support for Ubuntu 18.04 LTS – which is great news for those who recently upgraded to the latest Ubuntu 18.04 LTS package.

    The package is mainly intended for Vega Frontier, Radeon Pro, Radeon Pro WX, and FirePro S/W graphics cards, and the entire driver stack is derived from the 18.20 driver branch which includes both PRO and All-Open driver options.

Kernel: Qualcomm/Atheros "Ath10k", FUSE and Code of Conduct

  • Linux's Qualcomm Ath10k Driver Getting WoWLAN, WCN3990 Support
    The Qualcomm/Atheros "Ath10k" Linux driver coming up in the Linux 4.20~5.0 kernel merge window is picking up two prominent features. First up, the Ath10k driver is finally having WoWLAN support -- Wake on Wireless LAN. WoWLAN has been supported by the kernel for years and more recently is getting picked up by Linux networking user-space configuration utilities. Ath10k is becoming the latest Linux wireless driver supporting WoWLAN (WIPHY_WOWLAN_NET_DETECT) for automatically waking up the system when within range of an a known SSID.
  • FUSE File-Systems Pick Up Another Performance Boost With Symlink Caching
    FUSE file-systems in user-space are set to be running faster with the upcoming Linux 4.20~5.0 kernel thanks to several performance optimizations. The FUSE kernel code for this next Linux kernel cycle already has a hash table optimization and separately is copy file range support for efficient file copy operations. Staged today into the FUSE tree for the next cycle was yet another performance-boosting patch.
  • Another Change Proposed For Linux's Code of Conduct
    With the Linux 4.19-rc8 kernel release overnight, one change not to be found in this latest Linux 4.19 release candidate are any alterations to the new Code of Conduct. The latest proposal forbids discussing off-topic matters while protecting any sentient being in the universe. While some immediate changes to the Linux kernel Code of Conduct have been talked about by upstream kernel developers, for 4.19-rc8 there are no changes yet. We'll presumably see some basic changes land this week ahead of Linux 4.19.0 expected next Sunday as not to have an unenforceable or flawed CoC found in a released kernel version.

Plasma 5.14 – Phasers on stun

Linux is much like the stock market. Moments of happiness broken by crises. Or is the other way around? Never mind. Today shall hopefully be a day of joy, for I am about to test Plasma 5.14, the latest version of this neat desktop environment. Recently, I’ve had a nice streak of good energy with Linux, mostly thanks to my experience with Slimbook Pro2, which I configured with Kubuntu Beaver. Let’s see if we can keep the momentum. Now, before we begin, there are more good news woven into this announcement. As you can imagine, you do need some kind of demonstrator to test the new desktop. Usually, it’s KDE neon, which offers a clean, lean, mean KDE-focused testing environment. You can boot into the live session, try the desktop, and if you like it, you can even install it. Indeed, neon is an integral part of my eight-boot setup on the Lenovo G50 machine. But what makes things really interesting is that neon has also switched to the latest Ubuntu LTS base. It now comes aligned to the 18.04 family, adorned with this brand new Plasma. Proceed. Read more
