日本电子维修技术 显卡Broadcom VC5 DRM 驱动程序开始使用 AMD GPU 调度
Eric Anholt of Broadcom is looking at making use of the AMDGPU DRM scheduler within the VC5 direct rendering manager driver.
In Linux 4.16, the AMDGPU scheduler code was punted off into a common area of the DRM subsystem due to interest stemming from the Etnaviv team in making use of this "marvelous" scheduler in their own driver. With Linux 4.17, Etnaviv is indeed making use of the AMDGPU scheduler that also is now known as just "drm/scheduler" after being generalized for use by other DRM drivers.
Etnaviv though isn't the only user as Eric Anholt as the VC4/VC5 lead driver developer is also thinking about using this new scheduker for the up and coming VideoCore V DRM code. Confirming this he was asking some questions on the mailing list about the best way of making use of this scheduler. (In there he also makes another VC6 reference as well.)

AMD这票开源的都是良心的BSD协议，MIT协议？

The open-source driver developers responsible for the reverse-engineered, open-source Vivante GC graphics driver "Etnaviv" have sent in the pull request of their updates for DRM-Next that is of material to be found in the upcoming Linux 4.17 development cycle.
The most notable addition to the Etnaviv Direct Rendering Manager driver for Linux 4.17 is that it's now wired into the DRM GPU scheduler, or rather it's the AMDGPU scheduler that was punted into the common DRM space. It will be interesting to see the impact of Etnaviv now making use of AMD's optimized GPU scheduler.
The Etnaviv DRM driver also has prep work for supporting the latest-generation GC7000L hardware. The GC7000L support is important since that is what's used by the NXP i.MX8 SoC that will be used by the Purism Librem 5 smartphone and other devices. But the actual GC7000L support in Etnaviv isn't expected until the Linux 4.18 kernel cycle.
The good news is that while the code hasn't yet landed, they have open-source 3D already running on the i.MX8M / GC7000 hardware.
The complete list of Etnaviv DRM changes for Linux 4.17 can be found via this pull request.
