If the pipe or output have been set to DPMSOff, then load detection will not
work correctly. Also, share the load detection configuration code between
crt and tv outputs.
|
|
Make the application of crtc desiredModes generic code instead of
per-driver by creating xf86SetDesiredModes from the code that was in EnterVT
and calling it.
Also, move the frame buffer clear until just before mode setting to make
sure things are mapped correctly.
|
|
New hooks replace explicit invocation of DPMS functions to manage mode
setting sequencing.
|
|
These two sources are placed in higher priority to the BIOS data when
available, since the BIOS data has proven unreliable. The BIOS data is still
read, and warnings printed if it doesn't match what we probe. The BIOS data
remains useful for the situation where we want to turn on LVDS but there is no
EDID available and no current mode programmed (i.e. booting with VGA or TV
connected).

Makes the mode setting logic device independent.
Magic rename hooks allow multiple drivers to provide the
generic code without name conflicts.
Rotation code requires special pixmap creation hook, and uses
Render to perform the actual rotation.
|
|
This makes the CRTCs now always run in gamma-enabled mode, rather than having
flaky logic for switching modes. Also, it should clear up issues with the LUTs
being uninitialized when outputs are first brought up.
|
|
Add the modelines specified in the per-output monitor and all of the default
modes to the list to each output. Prune the resulting list to specified sync
limits and virtual sizes. Sort the resulting mode list on
preferred/size/refresh.

It compiles. It definitely doesn't run.
|
|
Outputs and Crtcs now have a driver-independent representation which should
permit generic code to control RandR 1.2 and startup configuration.
|
|
This also replaces calls to compat code with the real names of the functions,
and slips #defines to an i830-namespaced version in when doing compat.
The current server version (7.1.99.2) is still left as requiring compat code,
since the version hasn't been bumped yet.
This also fixes some failures to call the compat code, and some failures to
actually compile the compat code. Oops.
|
|
The X Server now has most of the mode helper functions we want, and we can
start removing compilation of our copies when the server is new enough.
|
|
Place crtc/output in separate structure at head
of driver private structure. Use this from the config code
to make it driver-independent. Still lots of effectively driver
independent code that continues to use driver dependent stuff,
but that will change.
|
|
Outputs and Crtcs are now split between 'generic'
and 'driver specific' pieces in the hope that more code
will be able to migrate to the xf86-generic layer.
Right now, the code remains tangled together, significant
work remains to tease the pieces apart. First the code
needs to be made to actually work as-is though.
|
|
Using pre-init computed RandR information, make reasonable
default choices for the output configuration at startup time.
Either some preferred size or a size which yields 96dpi is chosen,
from which other monitors are set to a similar size. The largest
size sets the screen size.
This needs to be extended to respect config file settings, but
those have not been defined yet.

This will be used by RandR, and should let us clean up some of the initial
display configuration, hopefully.
Also, analog hotplug-based detection is now enabled on G965.

All the SDVO code should now be in lower case rather than StudlyCaps.
This also adjusts the I2C setup to create a bus per SDVO output we set up.
The previous setup with shared buses was failing in some circumstances, which
is probably due to the lack of refcounting in xf86i2c.c.
|

This is not a very clean interface, as a number of outputs require tweaks to
the DPLL registers. When possible, the DPLLs are just adjusted in the
per-output post_set_mode, which happens just after the DPLL is enabled.
However, this seems better than the previous method of having all outputs
programmed in the same function.

Also add code to deal with disabling pipes.
|
|
This is not entirely what I'd like to see, but it's at least functional.
Limitations:
Can't disable/enable crtcs
Can't move outputs on/off crtcs
But, it does handle monitor hot-plug, detecting changes in VGA and SDVO
status on-the fly. Which makes for good demo material.
|
|
This method is slower (~5ms), but works on older chipsets. Also, load-based
detection is disabled, as it can be fooled by other outputs on the pipe being
active, such as LVDS.

slave address on the first device as well. This gets me to the point of
bringing up some modes on my device.

replaced by symbolic names in many places. I tried to restrain myself from
functional changes in airlied's code in this pass.

and AdjustFrame. Rename AdjustFrame to reflect the fact that it doesn't touch
the BIOS.

doesn't have BIOS-setup workarounds. Multihead behavior may be wrong, and it is
all untested.
