drm: use the right function name in documentation

2016-10-10T09:24:10+00:00

There is no late_unregister(), it looks like the comment meant
late_register(). Also fix a typo while at it.

drm/prime: Take a ref on the drm_dev when exporting a dma_buf

2016-10-05T13:30:32+00:00

dma_buf may live a long time, longer than the last direct user of the
driver. We already hold a reference to the owner module (that prevents
the object code from disappearing), but there is no reference to the
drm_dev - so the pointers to the driver backend themselves may vanish.

v2: Resist temptation to fix the bug in armada_gem.c not setting the
correct flags on the exported dma-buf (it should pass the flags through
and not be arbitrarily setting O_RDWR).

Use a common wrapper for exporting the dmabuf and acquiring the
reference to the drm_device.

drm/prime: Pass the right module owner through to dma_buf_export()

2016-10-05T13:29:08+00:00

dma_buf_export() adds a reference to the owning module to the dmabuf (to
prevent the driver from being unloaded whilst a third party still refers
to the dmabuf). However, drm_gem_prime_export() was passing its own
THIS_MODULE (i.e. drm.ko) rather than the driver. Extract the right
owner from the device->fops instead.

v2: Use C99 initializers to zero out unset elements of
dma_buf_export_info
v3: Extract the right module from dev->fops.

drm: simple_kms_helper: Add prepare_fb and cleanup_fb hooks

2016-10-05T13:18:02+00:00

Add .prepare_fb and .cleanup_fb plane hooks into the drm_simple_kms.
These can be used by drivers to call ie. the drm_fb_cma_setup_fence()
helper.

drm/fb-helper: add DRM_FB_HELPER_DEFAULT_OPS for fb_ops

2016-10-04T06:23:16+00:00

The define DRM_FB_HELPER_DEFAULT_OPS provides the drm_fb_helper default
implementations for functions in struct fb_ops. A drm driver can use it
like:

    static struct fb_ops drm_fbdev_cma_ops = {
        .owner          = THIS_MODULE,
        DRM_FB_HELPER_DEFAULT_OPS,
        /* driver specific implementations */
    };

drm: Document caveats around atomic event handling

2016-10-04T06:23:15+00:00

It's not that obvious how a driver can all race the atomic commit with
handling the completion event. And there's unfortunately a pile of
drivers with rather bad event handling which misdirect people into the
wrong direction.

Try to remedy this by documenting everything better.

v2: Type fixes Alex spotted.

v3: More typos Alex spotted.

drm: Simplify drm_printk to reduce object size quite a bit

2016-10-04T06:23:14+00:00

Remove function name and special " *ERROR*" from argument list

$ size drivers/gpu/drm/built-in.o* (x86-32 defconfig, most drm selected)
   text	   data	    bss	    dec	    hex	filename
5635366	 182579	  14328	5832273	 58fe51	drivers/gpu/drm/built-in.o.new
5779552	 182579	  14328	5976459	 5b318b	drivers/gpu/drm/built-in.o.old

Using "%ps", __builtin_return_address(0) is the same as "%s", __func__
except for static inlines, but it's more or less the same output.

Miscellanea:

o Convert args... to ##__VA_ARGS__
o The equivalent DRM_DEV_ macros are rarely used and not
  worth conversion
