    Phoronix: AMD Submits Initial AMDGPU Graphics Driver Improvements Ahead Of Linux 5.1

    The initial batch of new AMDGPU feature changes slated for the Linux 5.1 were sent out on Friday evening for staging in DRM-Next until the 5.1 kernel merge window opens at the end of February or early March...

    Any chances we will get proper reset mechanism for VM's for Polaris and Vega cards? It's silly that i have to reboot my host every time i run VM because when i try to launch it second time - vm hangs. Also, support for proper amdgpu driver unloading would be usefull so my Polaris GPU can be switched between host an VM.
    Now, it's time to test if 5.0-rc4 kernel fixes problems with kms on my Ryzen APU introduced in 4.20 series...

    It's more like the inverse... People do not care much about Vega, and that's why it has some bugs that really disturb me. For example,- wait, I'll be back.

    *argh, screw this. When this happens there is no way out, other than rebooting, and therefore losing my work!*

    DCC is a technique for improving effective memory bandwidth and from what I can tell this is improvement to how it can be used. AMD's lower end cards are obviously going to be the main recipients of any performance benefit due to the higher end ones having massive memory bandwidth thanks to HBM and the massively wide buses that go with it (2048 lanes when planar memory very rarely goes beyond 384, 256 being the most common bus width). Not that there aren't cases where even HBM equipped cards become memory bandwidth constrained, 4k gaming being the obvious use case.

    I'm looking forward to NAVI hoping for day1 Linux driver support (that rx590 episode hopefully woke up everybody involved).

    - Support for Delta Color Compression (DCC) on scanout surfaces.
    this should improve performance, right?

    That's actually a lot of cool changes.
    I forget - have we seen benchmarks of PowerPlay vs the old DPM?
