- This avoids returning with a mode count of 0, thus not allocating space for the 2nd ioctl.

We need to initialize the edid_blob_ptr to NULL when we init a connector,
otherwise drm_mode_connector_update_edid_property may think there's a valid
EDID lying around and try to destroy it, causing a crash.
|
|
Idea being if you want to add new crtc/output/encoder dynamically later,
you just increase the generation counter and userspace should re-read
all the resources

Move TTM code into the driver
|
|
This creates a default group attached to the legacy drm minor nodes.
It covers all the objects in the set. make set resources only return
objects for this set. Need to fix up other functions to only work on
objects in their allowed set.
|
|
handle crtc/encoders/connectors/fb/mode/property/blob using this system.
|
|
Not 100% sure this is a good idea, but I think I'd rather things
communicate with bo handles not fb ids.
|

This asks the driver to suggest the best encoder for the connector
during the pick crtcs stage.
Need to also do this during mode setting stages
|
|
Migrated the output mode collection into the helper.
|
|
|
|
Move dpms into the helper functions.
Move crtc into the encoder.
Move disable unused functions into the helper.
|
|
|
|
Okay we have crtc, encoder and connectors.
No more outputs exposed beyond driver internals
I've broken intel tv connector stuff.
Really for TV we should have one TV connector, with a sub property for the
type of signal been driven over it
|
|
Time to do some renaming on the connectors I think

Use subclassing from the drivers to allocate the objects. This saves
two objects being allocated for each crtc/output and generally makes
exit paths cleaner.
|
|
This splits a lot of the core modesetting code out into a file of
helper functions, that are only called from themselves and/or the driver.
The driver gets called into more often or can call these functions from itself
if it is a helper using driver.
I've broken framebuffer resize doing this but I didn't like the API for that
in any case.

Makes printing modelines from some routines easier.

drm_crtc->fb may point to NULL, f.e X server will allocate a new fb
and assign it to the CRTC at startup, when X server exits, it will destroy
the allocated fb, making drm_crtc->fb points to NULL.

It needs to take arguments from the caller about supported TV formats,
so declare it in drm_crtc.h and export it.
|
|
Cleanup some random cruft left over from the initial port.
|
|
Some fields had snuck into the drm_output structure. Put them back and
fill in more stuff from the EDID block.
|
|
Put off registering new outputs with sysfs until they're properly configured,
or we may get duplicates if the type hasn't been set yet (as is the case with
SDVO initialization). This also means moving de-registration into the cleanup
function instead of output destroy, since the latter occurs during the normal
course of setup when an output isn't found (and therefore not registered with
sysfs yet.
|

This patch ties outputs, output properties and hotplug events into the
DRM core. Each output has a corresponding directory under the primary
DRM device (usually card0) containing dpms, edid, modes, and connection
status files.
New hotplug change events occur when outputs are added or hotplug events
are detected.
|
|
Also adjust i915 irq handling as it follows the 16bit'ism's
of the i8xx series.
|
|
just flip the framebuffer in when required.

Allow mode to be set with fb_id set to -1, meaning set
the mode with the current fb (if we have one bound).
Allow intelfb to hook back up it's fb if modesetting
clears it (maybe temporary).
Move any crtc->fb related register changes to set_base
in intel_fb.
General intelfb cleanups.
