Maybe should add that ubunut/suse folks seem ok. Also, it's for libva, in the past that's been very far down the list of contentious topics.

Hi all, I would like to have some Acked-by's from you, the distro media folks Cc'd here, to document your intent to start using Intel's new media driver[1]. So if you recognize yourself (or are otherwise interested), please read on. TL;DR Distro folks, please give your Acked-by on patch [5/6] I believe most are already aware of the situation that Intel is moving to the new codebase for libva backend to support new Intel integrated graphics devices. The existing intel-libva-driver will be continue to be be supported for pre-Icelake platforms (<Gen11). Icelake and further platforms will only be supported from the new codebase. There's the complication that some Icelake features of the new driver will require new kernel uAPIs to work... But the new driver has not yet been well-established in the community from perspective of fulfilling [2]. This is very much due to the demand being low as Icelake is not widely available yet. So it's bit of a chicken and egg problem as we have a new platform *and* a new codebase for it simultaneously. Ahead of that community adoption, to ensure that Icelake has good kernel support from day one, we'd like to merge kernel support for the parts that have functional effect (this series). This is to avoid the scenario where end users have to update their distro kernels, like happened with Skylake. So if I could get Acked-by's from distro folks on the patch [5/6] that adds the new uAPI. That would document their intent to become an active user of the media-driver[1]. If that happens in the next week or two, it would mean that Icelake hardware features would be supported in kernel version 5.1 fully from kernel driver point of view. The new uAPI is needed to make VME feature functionally work on Icelake. It's pretty much a simple enable/disable switch for hardware configuration that only includes hardware slices compatible with the VME workload. So it's currently limited to the required on/off choice to keep things straightforward. The uAPI can be extended in the future for possible performance gains for more fine-grained control. VME is shared function to handle motion estimation. One intended usercase is in Hierarchical Motion Estimation (HME) media kernel. It provides a bigger search range with reduced cost for the search. HME should improve the encode quality with scenarios where the video has a lot of motion in it. Carl (Cc'd) can provide more details if needed. The respective IGT tests are reviewed and can be found at: https://patchwork.freedesktop.org/series/49190/ The userspace changes are reviewed and rebased here: https://github.com/intel/media-driver/pull/271 https://github.com/intel/media-driver/pull/463 Best Regards, Joonas Lahtinen Cc: dri-devel@lists.freedesktop.org Cc: Timo Aaltonen <timo.aaltonen@canonical.com> Cc: Takashi Iwai <tiwai@suse.de> Cc: Stephane Marchesin <stephane.marchesin@gmail.com> Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Vetter <daniel@ffwll.ch> PS. This series might result in some CI failures reported as it adds new uAPI and Patchwork / CI synchronization of tests and kernel is currently WIP.
