Hello, This is the second version of the kernel driver meant to support new Mali GPUs which are delegating the scheduling to a firmware. The RFC has been dropped as the major blocking points have been addressed (request to use drm_sched, request to implement a VM_BIND-like ioctl, request to use drm_gpuva_mgr for the VM logic, lack of PM/devfreq support). This series is based on drm-misc-next and depends on some drm_sched [1] and iommu [2] changes. A branch containing all those dependencies is available here[3], and here [4] is another one containing all the patches needed to have a working GPU on rk3588 on top. The CSF firmware binary can be found here[5]. The mesa branch used to test this new driver is available here [6]. It's still under development and it's just a gallium driver right now, but we are working on that ;-). Here is a non-exaustive changelog, check each commit for a detailed changelog. v2: - Rename the driver (pancsf -> panthor) - Split the commit adding the driver to ease review - Use drm_sched for dependency tracking/job submission - Add a VM_BIND ioctl - Add the concept of exclusive VM for BOs that are only ever mapped to a single VM - Document the code and uAPI - Add a DT binding doc I tried to Cc anyone that was involved in any development of the code I picked from panfrost, so they can acknowledge the GPL2 -> MIT+GPL2 change. If I missed someone, please let me know.
