| * drm/radeon: add properties to configure the width of the underscan bordersMarius Gröger2010-10-061-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows for a more exact fitting on the physical display. The new properties default to zero which corresponds to the previous underscan border width[height] formula: (display_width[display_width] >> 5) + 16. Example to set a horizontal border width of 30 and a vertikal border height of 22: xrandr --output HDMI-0 --set underscan on --set "underscan hborder" 30 --set "underscan vborder" 22 Signed-off-by: Marius Gröger <marius.groeger@googlemail.com> Reviewed-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
* | radeon, kdb, kms: Save and restore the LUT on atomic KMS enter/exitJason Wessel2010-10-061-0/+32
|/ | | | | | | | | | | | | | When changing VTs non-atomically the kernel works in conjunction with the Xserver in user space and receives the LUT information from the Xserver via a system call. When changing modes atomically for kdb, this information must be saved and restored without disturbing user space as if nothing ever happened.

* drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie2010-10-011-1/+2
| | | | | | | | | | | | | | | | | | | There were lots of places being inconsistent since handle count looked like a kref but it really wasn't. Fix this my just making handle count an atomic on the object, and have it increase the normal object kref. Now i915/radeon/nouveau drivers can drop the normal reference on userspace object creation, and have the handle hold it. This patch fixes a memory leak or corruption on unload, because the driver had no way of knowing if a handle had been actually added for this object, and the fbcon object needed to know this to clean itself up properly.

| | | | | | | | | | | When enabling underscan for hdmi monitors, attempt to detect whether we are driving a TV or a monitor. The should hopefully prevent underscan from being enabled on monitors attached via hdmi that do not overscan the image. Only enable underscan if the mode is a common hdtv mode (480p, 720p, etc.).

"best_error" is also unsigned so "best_error - 100" could be a large number instead of a negative.

You can select the pm method by echoing the selected method ("dynpm" or "profile") to power_method in sysfs. - Expose basic 4 profile in profile method "default" - default clocks "auto" - select between low and high based on ac/dc state "low" - DC, low power mode "high" - AC, performance mode The current base profile is "default", but it should switched to "auto" once we've tested on more systems. Switching the state is a matter of echoing the requested profile to power_profile in sysfs. The lowest power states are selected automatically when dpms turns the monitors off in all states but default. - Remove dynamic fence-based reclocking for the moment. We can revisit this later once we have basic pm in. - Move pm init/fini to modesetting path. pm is tightly coupled with display state. Make sure display side is initialized before pm. - Add pm suspend/resume functions to make sure pm state is properly reinitialized on resume. - Remove dynpm module option.
