2010-11-22drm/kms/radeon: Add support for precise vblank timestamping.Mario Kleiner
This patch adds new functions for use by the drm core: .get_vblank_timestamp() provides a precise timestamp for the end of the most recent (or current) vblank interval of a given crtc, as needed for the DRI2 implementation of the OML_sync_control extension. It is a thin wrapper around the drm function drm_calc_vbltimestamp_from_scanoutpos() which does almost all the work and is shared across drivers. .get_scanout_position() provides the current horizontal and vertical video scanout position and "in vblank" status of a given crtc, as needed by the drm for use by drm_calc_vbltimestamp_from_scanoutpos(). The function is also used by the dynamic gpu reclocking code to determine when it is safe to reclock inside vblank. For that purpose radeon_pm_in_vbl() is modified to accomodate a small change in the function prototype of the radeon_get_crtc_scanoutpos() which is hooked up to .get_scanout_position(). This code has been tested on AVIVO hardware, a RV530 (ATI Mobility Radeon X1600) in a Intel Core-2 Duo MacBookPro and some R600 variant (FireGL V7600) in a single cpu AMD Athlon 64 PC.

2010-10-06drm/radeon: Add function for display scanout position query.Mario Kleiner
radeon_get_crtc_scanoutpos() returns the current horizontal and vertical scanout position of a crtc. It also reports if the display scanout is currently inside the vblank area. hpos reports current horizontal pixel scanout position. vpos reports the current scanned out line as a value >= 0 in active scanout. If the scanout is inside vblank area, it reports a negative value, the number of scanlines until end of vblank aka start of active scanout, e.g., -3 == "At most 3 scanlines until end of vblank". This code is derived from radeon_pm_in_vbl(), tested on R500 and R600.

2010-10-01drm/gem: handlecount isn't really a kref so don't make it one.Dave Airlie
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.

2010-08-02drm: radeon: fix sign bugDan Carpenter
The "error" variable is unsigned so it's never less than zero. I changed it to check if (freq < current_freq) directly. "best_error" is also unsigned so "best_error - 100" could be a large number instead of a negative. Since "error" is unsigned it is never less than a negative and so the cases where "best_error" is less than or equal to 100 are false.

2010-05-18drm/radeon/kms/pm: rework power managementAlex Deucher
- Separate dynpm and profile based power management methods. 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.
