* drm: Stop using drm_vblank_count() as the hw frame counterVille Syrjälä2015-10-071-1/+1
| | | | | | | | | | | | | | | | | drm_vblank_count() returns the software counter. We should not pretend it's the hw counter since we use the hw counter to figuere out what the software counter value should be. So instead provide a new function drm_vblank_no_hw_counter() for drivers that don't have a real hw counter. The new function simply returns 0, which is about the only thing it can do.

* drm/rockchip: Don't grab dev->struct_mutex for in mmap offset ioctlDaniel Vetter2015-08-111-8/+4
| | | | | | | | | | | | | | | | | | | | Since David Herrmann's mmap vma manager rework we don't need to grab dev->struct_mutex any more to prevent races when looking up the mmap offset. Drop it and instead don't forget to use the unref_unlocked variant (since the drm core still cares). Aside: I stumbled over the mmap handler which directly does a dma_mmap_attrs. But totally fails to grab a reference on the underlying object and hence looks like it happily just leaks the ptes since there's no guarantee the mmap isn't still around when gem_free_object is called. Which the kerneldoc of dma_mmap_attrs explicitly forbids. v2: Fixup compile fail 0-day spotted.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 765d5b9c2b72f5b9 ("fbdev: fbcon: select VT_HW_CONSOLE_BINDING") made FRAMEBUFFER_CONSOLE always select VT_HW_CONSOLE_BINDING, but forgot to remove select VT_HW_CONSOLE_BINDING if FRAMEBUFFER_CONSOLE from the individual drivers' sections that already did this before. Remove it, also from new drivers. Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
