We want to copy to card_res->modes + copied, not &card_res->modes + copied.
|
|
Since the drm_mode_card_res structure contains user pointers, we have to use
put_user and copy_to_user to write stuff out. The DRM ioctl wrapper will only
take care of copying the base drm_mode_card_res struct, not the included
arrays.

Mostly removing typedefs that snuck into the modesetting code and
updating to the latest TTM APIs. As of today, the i915 driver builds,
but there are likely to be problems, so debugging and bugfixes will
come next.

held across any operations that modify mode lists, crtc config, output
config, etc. It should be taken at high level entry points (currently just
initial config and user IOCTL).
Seems to work ok on my system, but needs more testing (with lockdep) and
review from some fresh eyes.

Lots of changes to merge with alanh's latest stuff:
o fix use of fb->pitch now that it has the right value
o add new helper for finding the CRTC given an FB
o fix new fb_probe/fb_remove functions to take a CRTC
o fixup callers of new FB routines
o port drm_fb changes to intel_fb
o check for errors after creating fb buffer object
o go back to using cfb_imageblit since the accel stubs aren't ready

places).
Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver. This will allow acceleration and better handling
of the command stream.

Change from DIRECTCOLOR to TRUECOLOR, and enable
support for PSEUDOCOLOR. DIRECTCOLOR support needs more work.
Add the ability to change the mode on the fbdev device.
Support depth 8, 15, 16 and 24 (and 32).
Add a /dev/fbX device per CRTC, but there's some code which
doesn't allocate the fbX device unless the output is actually
enabled. Read the code on this as it impacts the fbcon map flags.
Pick CRTC's based on the available outputs. More work could
be done here to match modes, so cloning could be achieved on
outputs. This fits more inline with what the X code does.

This allows userspace to specify modes and add them to the modesetting
system and attach modes to outputs
|
|
The mode list sets all the output modes to UNVERIFIED, then probes a new list,
If a mode is on the new list and not on the old, it adds it to the old,
if a mode is on the new list and old, it just updates the status to the new
mode status.
If a mode is on the old list and not on the new, prune invalid modes should
remove all UNVERIFIED modes

This snippet adds a standard 640x480 @ 60Hz mode when
that occurs, so we can continue with a basic mode.
Should we do this here though ???

remove i915_driver_load fb related stuff. Add a small helper for setting up

We need to keep a list of user created fbs to nuke on master exit.
We also need to use the bo properly.

- allow drm_buffer_object_create to be called w/o dev_mapping
- fixup i915 init code to allocate memory, fb and set modes right
- pass fb to drm_initial_config for setup
- change some debug output to make it easier to spot
- fixup lvds code to use DDC probing correctly

So far I can load fbcon, once I use my miniglx to add a framebuffer.
fbcon doesn't show anything on screen but baby steps and all that.
