* No choice as to use kernel module with my own user space interface. Yeah, hate me kernel developers, i know, it's ugly but NVIDIA does it too ('''/dev/nvidia''', '''/dev/nvidiactl''' and '''nvidia.ko''').

===DRM Device File===
* On FreeBSD, it's '''cdev'''.
* '''si_drv1''' points to '''struct drm_device'''
===Memory===
* There are several types of memory: VRAM (video RAM or memory on GPU), GART (system memory mapped into GPU address space) and CPU (system memory but NOT mapped into GPU address space)
* Implement memory heap managers
* Radeon driver is a good example how to manage VRAM and GART memory heaps. The user specifies memory type, alignment and size. The driver returns the offset of allocated memory region to user. The offset is the handle of allocated memory block.
* http://fxr.watson.org/fxr/source/dev/drm/radeon_mem.c
* Radeon driver supports memory types: VRAM and GART
* Nouveau driver supports memory types: VRAM, GART and CPU
* '''mmap syscall''' is used to map memory buffers into user-space. '''offset''' passed to mmap syscall is the handle of a memory map created previously with '''IOCTL DRM_IOCTL_ADDMAP'''. The handle is returned to user from IOCTL that creates the map.
* http://fxr.watson.org/fxr/source/dev/drm/drm_vm.c
* '''drmMap''' just calls mmap syscall and passes map handle as offset.
* Interesting discussion about DRM map handles: http://comments.gmane.org/gmane.comp.video.dri.devel/19657
* FreeBSD DRM framework uses '''alloc_unr''' to allocate unique map handles
