  • IGT Is Helping Keep Intel's Display Driver & Other DRM/KMS Drivers In Good Shape

    Formerly known as Intel GPU Tools, the scope of "IGT" has been expanding now for providing tools and functionality testing not only around the Intel DRM/KMS driver but also the other mainline Linux display drivers.

    The tool goes just by IGT these days with the scope expanding beyond just supporting the Intel driver, but the focus remains on providing good test coverage and various features for testing DRM/KMS code. IGT ships with tests around various hardware/driver-specific interfaces as well as PRIME buffer sharing, kernel mode-setting, GEM memory management, and other test/tooling programs.

  • Intel Sends In Their Last Batch Of Graphics Driver Feature Updates For Linux 5.1

    As anticipated with the DRM-Next feature cutoff upon us for the next kernel cycle, Intel's open-source developers today sent out their last planned set of feature changes slated for the Linux 5.1 kernel cycle.

    In preparation for the Linux 5.1 kernel cycle that will officially get underway when Linux 5.0 debuts around the end of February, Intel has already queued a lot of new material into the DRM-Next staging area. That earlier work most notably includes enabling Fastboot graphics by default for newer generations of graphics hardware for enhancing the boot experience. That Fastboot support by default is for Skylake and newer as well as various Atom SoCs. Also notable is Coffeelake GVT support for graphics virtualization. And the pull requests to DRM-Next over recent weeks have also included various Icelake fixes and other low-level improvements and code clean-ups.

  • AMDGPU Sends In More Linux 5.1 Updates With Seamless Boot Bits, FreeSync Fixes

    With the cutoff this weekend of new material in DRM-Next that hopes to make it in the upcoming Linux 5.1 cycle, besides Intel sending in a last batch, so has AMD with some more AMDGPU changes for this next version of the Linux kernel.

    The Linux 5.1 material for AMDGPU already queued include PCI Express bandwidth utilization being exported to user-space now via sysfs, initial BACO (Bus Active, Chip Off) support for Vega, exposing shader and memory clocks via hwmon, delta color compression on scan-out surfaces, and other changes. A secondary pull brought Vega 20 fixes and other miscellaneous fixes.
