2012-09-27drm/radeon: work around KMS modeset limitations in PLL allocation (v2)Alex Deucher
Since the current KMS API sets the mode independantly on each crtc, we may end up with resource conflicts. The PLL allocation is one of those cases. In the following example we have 3 crtcs in use driving 2 DVI connectors and 1 DP connector. On the initial kernel modeset for fbdev, the display topology ends up as follows: crtc0 -> DP-0 crtc1 -> DVI-0 crtc2 -> DVI-1 Because this is the first modeset, all of the PLLs are available as none have been assigned. So we end up with the following: crtc0 uses DCPLL crtc1 uses PPLL2 crtc2 uses PPLL1 When X starts, it assigns a different topology: crtc0 -> DVI-0 crtc1 -> DP-0 crtc2 -> DVI-1 However, since the KMS API is per crtc, we set the mode on each crtc independantly. When it comes time to set the mode on crtc0, the topology for crtc1 and crtc2 are still intact. crtc1 and crtc2 are already assigned PPLL2 and PPLL1 so when it comes time to set the mode on crtc0, crtc1 and crtc2 have not been torn down yet, so there appears to be no PLLs available. In reality, we are reconfiguring the entire display topology, however, since each crtc is handled independantly, we don't know that in the driver at each crtc mode set time. This patch checks to see if the same connector is being driven by another crtc, and if so, uses the PLL already associated with it. v2: store connector in the radeon crtc struct, simplify checking.

2012-09-20drm/radeon: rework crtc pll setup to better support PPLL sharingAlex Deucher

2012-09-20drm/radeon: allow PPLL sharing on non-DP displaysAlex Deucher
If several non-DP displays use the same pixel clock we can use the same PPLL for all of them. If all relevant displays have the same pixel clock, this allows the driver to: - use fewer PPLLs which saves power - support more than two non-DP displays on DCE4+ The current drm modesetting infrastructure doesn't really provide a good framework for validating combinations that work or won't work, so it's possible you could go from a working configuration to a non-working one by changing the mode a one of the displays. However, there this is better than what was there before. Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2012-09-20drm/radeon/dce3: use a single PPLL for all DP displaysAlex Deucher

2012-09-20drm/radeon: rework pll selection (v4)Alex Deucher
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>

2012-09-20drm/radeon: rework the VM code a bit more (v2)Christian König

2012-09-20ACPI video: allow events handlers to veto the keypressLuca Tettamanti
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>
