Qualcomm's QuIC Adds Open-Source DRM For Brand New Snapdragon 820

HARDWARE --
Qualcomm's Innovation Center (QuIC) sent out patches this morning for providing open-source hardware enablement for their new Snapdragon 820 (MSM8996) via the free software MSM DRM/KMS driver.

In late 2014 was the big surprise when Qualcomm's QuIC began contributing to the MSM DRM driver that was started as a reverse-engineered, community-driven DRM display driver led by Rob Clark who has also been developing the Freedreno Gallium3D driver for reverse-engineered Qualcomm 3D GPU support.

That open-source DRM driver enablement work has continued and the latest patches out of their innovation center offer MSM8996 support, a.k.a. the Snapdragon 820.

What makes this even more amazing? For those not paying attention to the mobile space, the Snapdragon 820 is very new with details on it still being released and it not yet shipping in devices. See the Snapdragon blog, "The Snapdragon 820 is the most powerful mobile processor we’ve ever made. So it only made sense that we would give it the most advanced modem we’ve ever designed. Qualcomm Technologies is proud to announce that the Snapdragon 820 will feature breakthrough LTE and Wi-Fi technologies, made possible by an integrated, and newly upgraded, X12 LTE modem."

The Snapdragon 820 uses a Adreno 530 graphics processor that right now has OpenGL ES 3.1 + AEP support while OpenGL ES 3.2 drivers are coming. The Adreno 500 series are Qualcomm's first graphics processors designed as well with Vulkan in mind. While there's the MSM8996 display support, it's a pity that QuIC isn't yet backing any open-source user-space via Freedreno Gallium3D.

The patch series (ten patches in total right now) for adding support to the MSM DRM driver explains, "This series of patches adds support for MSM8996, including MDP5 v1.7. Note that only the HDMI interface is supported for now."
