      drm/ttm: remove no_wait_reserve, v3 · 97a875cb
      Maarten Lankhorst 提交于
      All items on the lru list are always reservable, so this is a stupid
      thing to keep. Not only that, it is used in a way which would
      guarantee deadlocks if it were ever to be set to block on reserve.
      
      This is a lot of churn, but mostly because of the removal of the
      argument which can be nested arbitrarily deeply in many places.
      
      No change of code in this patch except removal of the no_wait_reserve
      argument, the previous patch removed the use of no_wait_reserve.
      
      v2:
       - Warn if -EBUSY is returned on reservation, all objects on the list
         should be reservable. Adjusted patch slightly due to conflicts.
      v3:
       - Focus on no_wait_reserve removal only.

      drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2) · 312fec14
      Dave Airlie 提交于
      This is the initial driver for the Aspeed Technologies chips found in
      servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
      doesn't support the AST11xx due to lack of hw to test it on, and them requiring
      different codepaths.
      
      This driver is intended to be used with xf86-video-modesetting in userspace.
      
      This driver has a slightly different design than other KMS drivers, but
      future server chips will probably share similiar setup. As these GPUs commonly
      have low video RAM, it doesn't make sense to put the kms console in VRAM
      always. This driver places the kms console into system RAM, and does dirty
      updates to a copy in video RAM. When userspace sets a new scanout buffer,
      it forcefully evicts the video RAM console, and X can create a framebuffer
      that can use all of of video RAM.
      
      This driver uses TTM but in a very simple fashion to control the eviction
      to system RAM of the console, and multiple servers.
      
      v2: add s/r support, fix Kconfig.
