* drm/radeon/dce3: use a single PPLL for all DP displaysAlex Deucher2012-09-201-0/+24
| | | | | | | If possible, use a single PPLL for multiple DP displays on DCE3.x. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* drm/radeon: rework pll selection (v4)Alex Deucher2012-09-201-34/+129
| | | | | | | | | | | | | | | | | | | | | For DP we can use the same PPLL for all active DP encoders. Take advantage of that to prevent cases where we may end up sharing a PPLL between DP and non-DP which won't work. Also clean up the code a bit. v2: - fix missing pll_id assignment in crtc init v3: - fix DP PPLL check - document functions - break in main encoder search loop after matching. no need to keep checking additional encoders. v4: - same as v3, but re-apply to drm-next as the corner cases are fixed properly in subsequent patches. fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54471 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* drm/radeon: rework the VM code a bit more (v2)Christian König2012-09-204-72/+154
| | | | | | | | | | | | | Roughly based on how nouveau is handling it. Instead of adding the bo_va when the address is set add the bo_va when the handle is opened, but set the address to zero until userspace tells us where to place it.

* drm/radeon: block the keypress on ATIF eventsLuca Tettamanti2012-09-201-1/+6
| | | | | | | | | The AMD ACPI interface may use ACPI_VIDEO_NOTIFY_PROBE to signal SBIOS requests; block the keypress in this case since the user did not actually press the mode switch key. Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
* ACPI video: allow events handlers to veto the keypressLuca Tettamanti2012-09-201-4/+4
| | | | | | | | | | | | | | | | The standard video events may be overloaded for device specific purposes. For example AMD ACPI interface overloads ACPI_VIDEO_NOTIFY_PROBE (0x81) to signal AMD-specific events. In such cases we don't want to send the keypress (KEY_SWITCHVIDEOMODE) to the userspace because the user did not press the mode switch key (the spurious keypress confuses the DE which usually changes the display configuration and messes up a dual-screen setup). This patch gives the handlers the chance to examine the event and block the keypress if the event is device specific. v2: refactor as suggested by Zhang Rui <rui.zhang@intel.com> Signed-off-by: Luca Tettamanti <kronos.it@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

* Replace int2float() with an optimized version.Steven Fuerst2012-09-201-23/+28
| | | | | | | | | | | | We use __fls() to find the most significant bit. Using that, the loop can be avoided. A second trick is to use the behaviour of the rotate instructions to expand the range of the unsigned int to float conversion to the full 32 bits in a branchless way. The routine is now exact up to 2^24. Above that, we truncate which is equivalent to rounding towards zero. Signed-off-by: Steven Fuerst <svfuerst@gmail.com>
