drm/radeon: workaround a hw bug on some radeon chipsets with all-0 EDIDs.

2011-06-16T06:30:54+00:00

Some RS690 chipsets seem to end up with floating connectors, either
a DVI connector isn't actually populated, or an add-in HDMI card
is available but not installed. In this case we seem to get a NULL byte
response for each byte of the i2c transaction, so we detect this
case and if we see it we don't do anymore DDC transactions on this
connector.

I've tested this on my RS690 without the HDMI card installed and
it seems to work fine.

drm: Take lock around probes for drm_fb_helper_hotplug_event

2011-05-16T02:01:43+00:00

We need to hold the dev->mode_config.mutex whilst detecting the output
status. But we also need to drop it for the call into
drm_fb_helper_single_fb_probe(), which indirectly acquires the lock when
attaching the fbcon.

Failure to do so exposes a race with normal output probing. Detected by
adding some warnings that the mutex is held to the backend detect routines:

drm: mm: fix debug output

2011-05-08T23:14:45+00:00

The looping helper didn't do anything due to a superficial
semicolon. Furthermore one of the two dump functions suffered
from copy&paste fail.

While staring at the code I've also noticed that the replace
helper (currently unused) is a bit broken.
