[v2,0/5] Replace hibmc code with generic implmentation

Message

Thomas Zimmermann Nov. 26, 2019, 9:15 a.m. UTC

The patch set replaces code in hibmc with generic implementation.

Patches 1 to 4 replace fbdev emuation, framebuffer and creation of
dumb buffers with respective code from DRM helpers. Patch 5 adds an
additional interface to debugfs that displays the allocated and free
areas in video memory.

The patches have only been compile-tested. Further testing is
appreciated.

v2:
	* split [3/4] into vram and hibmc changes
	* verify that pitch_align is power of two

Thomas Zimmermann (5):
  drm/hisilicon/hibmc: Switch to generic fbdev emulation
  drm/hisilicon/hibmc: Replace struct hibmc_framebuffer with generic
    code
  drm/vram: Support scanline alignment for dumb buffers
  drm/hisilicon/hibmc: Implement hibmc_dumb_create() with generic
    helpers
  drm/hisilicon/hibmc: Export VRAM MM information to debugfs
