      drm/radeon: introduce kernel modesetting for radeon hardware · 771fe6b9
      Jerome Glisse 提交于
      Add kernel modesetting support to radeon driver, use the ttm memory
      manager to manage memory and DRM/GEM to provide userspace API.
      In order to avoid backward compatibility issue and to allow clean
      design and code the radeon kernel modesetting use different code path
      than old radeon/drm driver.
      
      When kernel modesetting is enabled the IOCTL of radeon/drm
      driver are considered as invalid and an error message is printed
      in the log and they return failure.
      
      KMS enabled userspace will use new API to talk with the radeon/drm
      driver. The new API provide functions to create/destroy/share/mmap
      buffer object which are then managed by the kernel memory manager
      (here TTM). In order to submit command to the GPU the userspace
      provide a buffer holding the command stream, along this buffer
      userspace have to provide a list of buffer object used by the
      command stream. The kernel radeon driver will then place buffer
      in GPU accessible memory and will update command stream to reflect
      the position of the different buffers.
      
      The kernel will also perform security check on command stream
      provided by the user, we want to catch and forbid any illegal use
      of the GPU such as DMA into random system memory or into memory
      not owned by the process supplying the command stream. This part
      of the code is still incomplete and this why we propose that patch
      as a staging driver addition, future security might forbid current
      experimental userspace to run.
      
      This code support the following hardware : R1XX,R2XX,R3XX,R4XX,R5XX
      (radeon up to X1950). Works is underway to provide support for R6XX,
      R7XX and newer hardware (radeon from HD2XXX to HD4XXX).

      drm: reorganise drm tree to be more future proof. · c0e09200
      Dave Airlie 提交于
      With the coming of kernel based modesetting and the memory manager stuff,
      the everything in one directory approach was getting very ugly and
      starting to be unmanageable.
      
      This restructures the drm along the lines of other kernel components.
      
      It creates a drivers/gpu/drm directory and moves the hw drivers into
      subdirectores. It moves the includes into an include/drm, and
      sets up the unifdef for the userspace headers we should be exporting.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
