From cdeaeb9dd762d7711241a62459dfb730b2cd0281 Mon Sep 17 00:00:00 2001 From: Danilo Krummrich Date: Thu, 24 Apr 2025 18:02:50 +0200 Subject: drm: nova-drm: add initial driver skeleton Add the initial nova-drm driver skeleton. nova-drm is connected to nova-core through the auxiliary bus and implements the DRM parts of the nova driver stack. For now, it implements the fundamental DRM abstractions, i.e. creates a DRM device and registers it, exposing a three sample IOCTLs. DRM_IOCTL_NOVA_GETPARAM - provides the PCI bar size from the bar that maps the GPUs VRAM from nova-core DRM_IOCTL_NOVA_GEM_CREATE - creates a new dummy DRM GEM object and returns a handle DRM_IOCTL_NOVA_GEM_INFO - provides metadata for the DRM GEM object behind a given handle I implemented a small userspace test suite [1] that utilizes this interface.
