GPU reset will drop all flips that are still in the ring. So after the reset, call update_plane() for all CRTCs to make sure the primary planes are scanning out from the correct buffer. Also finish all pending flips. That means user space will get its page flip events and won't get stuck waiting for them. v2: Explicitly finish page flips instead of relying on FLIP_DONE interrupt being generated by the base address update. v3: Make two loops over crtcs to avoid deadlocks with the crtc mutex Signed-off-by:Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Since obj->pending_flips was never set, intel_pipe_set_base() never actually waited for pending page flips to complete. We really do want to wait for the pending flips, because otherwise the mmio surface base address update could overtake the flip, and you could end up with an old frame on the screen once the flip really completes. Just call intel_crtc_wait_pending_flips() prior to calling intel_pipe_set_base() instead of calling just intel_finish_fb() from intel_pipe_set_base(). Moving the call outside of intel_pipe_set_base() avoids calling it twice from the full modeset path. v2: Wait for pending flips w/o holding struct_mutex Signed-off-by:

KMS drivers can potentially restore the display configuration without userspace help. Such drivers can can call a new funciton, pm_vt_switch_required(false) if they support this feature. In that case, the PM layer won't VT switch to the suspend console at suspend time and then back to the original VT on resume, but rather leave things alone for a nicer looking suspend and resume sequence. v2: make a function so we can handle multiple drivers (Alan) v3: use a list to track device requests (Rafael) v4: Squash in build fix from Jesse for CONFIG_VT_CONSOLE_SLEEP=n v5: Squash in patch from Wu Fengguang to add a few missing static qualifiers. v6: Add missing EXPORT_SYMBOL.

Whilst IOMMU is enabled for the Intel GPU on Ironlake, it appears that using WC writes to update the PTE on the GPU fails miserably. The result looks like the majority of the writes do not land leading to lots of screen corruption and a hard system hang. v2: s/</<=/ to preserve the current exclusion of Sandybridge Reported-by:

HSW no longer has the PIPECONF bit for limited range RGB output. Instead the pipe CSC unit must be used to perform that task. The CSC pre offset are set to 0, since the incoming data is full [0:255] range RGB, the coefficients are programmed to compress the data into [0:219] range, and then we use either the CSC_MODE black screen offset bit, or the CSC post offsets to shift the data to the correct [16:235] range. Also have to change the confiuration of all planes so that the data is sent through the pipe CSC unit. For simplicity send the plane data through the pipe CSC unit always, and in case full range output is requested, the pipe CSC unit is set up with an identity transform to pass the plane data through unchanged. I've been told by some hardware people that the use of the pipe CSC unit shouldn't result in any measurable increase in power consumption numbers. Signed-off-by:

The bit controlling whether PIPE_CONTROL DW/QW write targets the global GTT or PPGTT moved moved from DW 2 bit 2 to DW 1 bit 24 on IVB. I verified on IVB that the fix is in fact effective.

The FDI link has supported link reversal to make the PCB layout engineer's life easier for quite a while and we have always presered this bit as we programmed FDI_RX_CTL with a read/modify/write sequence. We're trying to take a bit more control over what the BIOS leaves in various register and with the introduction of DDI, started to program FDI_RX_CTL fully. There's a fused bit to indicate DMI link reversal and FDI defaults to mirroring that configuration. We have a bit to override that behaviour that we need to preserve from the BIOS. Signed-off-by:

Support for real RGB332 is a rarity, most hardware only really support C8. So use C8 instead of RGB332 when determining the format based on depth/bpp. This fixes 8bpp fbcon on i915, since i915 will only accept C8 and not RGB332.

As explained by Chris Wilson gem objects in stolen memory are always coherent with the GPU so we don't need to ever flush the CPU caches for these. This fixes a breakage - at least with the compact sg patches applied - during the resume/restore gtt mappings path, when we tried to clflush an FB object in stolen memory, but since stolen objects don't have backing pages we passed an invalid page pointer to drm_clflush_page().

If a GPU reset occurs while a page flip has been submitted to the ring, the flip will never complete once the ring has been reset. The GPU reset can be detected by sampling the reset_counter before the flip is submitted, and then while waiting for the flip, the sampled counter is compared with the current reset_counter value.

With the previous patch "drm/i915: disable shared panel fitter for pipe" we now disable the panel fitter at the right spot in the modeset sequence in the crtc functions on all platforms. Hence the disabling in intel_disable_lvds is no longer required and potentially harmful (since the plane is still enabled at this point). Similarly on the enabling side we enable the panel fitter in the lvds callback only once the plane is enabled. Which is too late. Hence move this into a new intel_pre_enable_lvds callback. Finally we can ditch lvds_encoder->pfit_dirty - this was required to work around the crtc helper semantics, but with the new i915 modeset infrastructure we should enable/disable the pfit only when enabling or disabling the entire output pipeline. So separate state tracking for the pfit is no longer required. Signed-off-by:

If encoder is switched off by BIOS, but the panel fitter is left on, we never try to turn off the panel fitter and leave it still attached to the pipe - which can cause blurry output elsewhere.

Some early bios versions seem to ship with the wrong tuning values for the MCH, possible resulting in pipe underruns under load. Especially on DP outputs this can lead to black screen, since DP really doesn't like an occasional whack from an underrun. Unfortunately the registers seem to be locked after boot, so the only thing we can do is politely point out issues and suggest a BIOS upgrade. Arthur Runyan pointed us at this issue while discussion DP bugs - thus far no confirmation from a bug report yet that it helps. But at least some of my machines here have wrong values, so this might be useful in understanding bug reports. v2: After a bit more discussion with Art and Ben we've decided to only the check the watermark values, since the OREF ones could be be a notch more aggressive on certain machines.
