VMware Publishes Set Of 33 Major GPU DRM Patches
Earlier this week I shared VMware might have a big GPU driver update for the Linux 3.14 kernel and now in time they have successfully delivered. This new "vmwgfx" virtual GPU driver adapts to their new virtual GPU (SVGA2) hardware revision.
SVGA2 Hardware Revision 11 will be a new version of the graphics processor they expose to VMware virtual machines for tapping and allowing guest VMs to have 3D hardware acceleration provided by the host.
The 11th hardware revision to the SVGA2 adapter introduces a concept of "guest backed objects" and resources. Thomas Hellstrom of VMware explained these fundamental VMware SVGA driver changes in a new mailing list post:
The device will in principle get all of its memory from the guest, which has big advantages from the device point of view.These VMware GPU DRM patches for the Linux 3.14 kernel can be found queued up on the dri-devel list until their landing in the drm-next tree and then in the next few weeks ahead in the mainline Linux Git repository.
