Try to make sure we find the power sequencer that the BIOS used by first looking for one which has the panel power enabled, then fall back to one with VDD force bit enabled, and finally look at just the port select bits. This should make us pick the correct power sequencer when the BIOS has already enabled the panel. Signed-off-by:

Introduce a new mutex (pps_mutex) to protect the power sequencer state. For now this state includes want_panel_vdd as well as the power sequencer registers.

IS_GEN8() is a bad check in the forcewake code due to bdw vs. chv differences. Use IS_BROADWELL() instead. The only actual bug here is that we currently call __gen7_gt_force_wake_mt_reset() on chv. On the other places we have checked for chv before using IS_GEN8(), but change them to use IS_BROADWELL() anyway to reduce the chance of accidents in the future. Signed-off-by:

Those debugfs files are prefixed by i915, the name of the kernel module, presumably to make the difference with files exposed by core DRM. Also, add a ',' at the end of the last entry. This is to ease the conflict resolution when rebasing internal patches that add a member at the end of the array. Without it, wiggle can't do its job as we need to modify an existing line (appending the ','). Signed-off-by:

Currently, CHV is using the same functions as HSW/BDW instead of the same functions as VLV. This looks wrong, especially since, for example, valleyview_modeset_global_resouces even has an IS_CHERRYVIEW check. This patch has the potential to fix display audio and the CHV CDCLK.

No point in calling intel_plane_restore() in .set_property() if the value didn't change. More importantly this papers over a bug where the current primary plane code forgets to update the user coordinates we store under intel_plane unless the primary plane .update_plane() hook is actually called. This means we have 0 in the coordinates straight after boot and any call to intel_restore_plane() (such as from restore_fbdev_mode()) will actually turn off the primary plane. This mess needs to be fixed properly but that's a bigger task and the first step there is killing off intel_pipe_set_base() and just calling the primary plane .update_plane() hook. For the immediate problem of black screen after boot this small patch is enough to hide it. The problem originates from these two commits: commit 3a5f87c2 Author: Thomas Wood <thomas.wood@intel.com> Date: Wed Aug 20 14:45:00 2014 +0100 drm: fix plane rotation when restoring fbdev configuration commit d91a2cb8e5104233c02bbde539bd4ee455ec12ac Author: Sonika Jindal <sonika.jindal@intel.com> Date: Fri Aug 22 14:06:04 2014 +0530 drm/i915: Add 180 degree primary plane rotation support Cc: Thomas Wood <thomas.wood@intel.com> Cc: Sonika Jindal <sonika.jindal@intel.com> Tested-by:

830M has problems when some of the pipes are disabled. Namely if a plane, DVO port etc. is currently assigned to a disabled pipe, it can't moved to the other pipe until the current pipe is also enabled. To keep things simple just leave both pipes running all the time. Ideally I think should turn the pipes off if neither is active, and when either becomes active we enable both. But that would reuquire proper atomic modeset support, and probably a bit of extra care in the order things get enabled. v2: Reorder wrt. double wide handling changes Signed-off-by:

830 really does want the pipe A quirk. The planes and ports don't react to any register writes unless the pipe currently attached to them is running, so it's impossible to move them to the other pipe unless both pipes are running. Also it's documented that the DPLL must be enabled on both pipes whenever it's needed. This reverts commit ac6696d3236bd61503f89a1a99680fd7894d5d53. Signed-off-by:

The vbt on my Fujitsu-Siemens Lifebook S6010 provides two 800x600 modes, 60Hz and 56Hz. The magic register values we have correspond to the 60Hz mode, and as I don't know how one would trick the VGA BIOS to set up the 56Hz mode we can't get the magic values for the orther mode. So when checking whether a mode is valid also check the pixel clock so that we filter out the 56Hz variant. Signed-off-by:

In my earlier rewrite I missed a few important registers. Thomas Richter noticed that they're needed to make his machine resume correctly. Looks like IEGD does a one time init of these three registers. We don't have a good one time init place in the ns2501 driver, so let's just stick them into the .mode_set() hook and see if that helps things along. Signed-off-by:

Try to use the same programming sequence as used by the IEGD driver. Also shovel the magic register values into a big static const array. The register values are actually the based on what the BIOS programs on the Fujitsu-Siemens Lifebook S6010. IEGD seemed to have hardcoded register values (which also enabled the scaler for 1024x768 mode). However those didn't actually work so well on the S6010. Possibly the pipe timings that got used didn't match the ns2501 configuration. Signed-off-by:
