Panthor DRM Driver For Arm Mali Graphics Working On User Submission Handling
Arm engineer Mihail Atanassov proposed a set of 'request for comments' patches this week for adding user submission support to the Panthor DRM driver that is used for handling newer Arm Mali graphics under Linux
The RFC patches posted on Monday are the initial design for handling user submission support with this newer Direct Rendering Manager driver. The goal of these changes is to allow userspace to control work submission to the FW/HW directly without kernel intervention in the common case, thereby reducing context switching overhead. Those interested in this user submission work for the Arm Panthor driver can find the RFC patches under review on the mailing list.
