  • 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: Linux 4.19 and Vega 20 PowerPlay

  • Power Management Updates Land In The Linux 4.19 Kernel
    Intel's Rafael Wysocki has submitted the ACPI and power management updates today for the Linux 4.19 kernel which were subsequently merged by Linus Torvalds.
  • Linux 4.19 Git Contains a lot of Performance Impacting Spectre Mitigation Updates
    Another round of commits regarding anti-Spectre security have landed up in the Linux 4.19 kernel git tree, which may have possible performance impacts for the kernel. While Spectre is still only a somewhat theoretical threat, as its entirely too slow to be used in a serious attack, many folks are taking its future potential quite seriously and arming up against it.
  • Linux 4.19 Kernel to Receive a Ton of Audio Hardware Updates for Improved Linux Sound Capabilities
    Linux audiophiles may have something to rejoice about, as a recent pull request from SUSE’s Takashi Iwai focuses on a plethora of sound subsystem updates for the Linux 4.19 kernel, including a lot of latest hardware support and overall improvements for Linux’s audio capabilities.
  • Updated Vega 20 Open-Source Driver Patches Posted, Including PSP & PowerPlay Support
    Back in May AMD posted initial open-source "Vega 20" patches and support for that yet-to-launch graphics processor was subsequently merged for the Linux 4.18 kernel. More of the Vega 20 AMDGPU kernel driver enablement has now been posted. This latest 69,910 lines of code -- before fretting, most of that is auto-generated header files for the GPU -- notably adds PSP (Platform Security Processor) and SMU (System Management Unit) for Vega 20. With the SMU enablement code, it's also now wired in to enable Vega 20 PowerPlay support as well as related power/clocking-functionality like OverDrive overclocking is also available.
