Many times in the past we have concluded that the cause of the GPU hang has been that the hw status page was stale, usually because the GPU and CPU disagreed over the address of the page. Having stumbled across yet another issue that seems to be related to the HWSP, it is time to include that information in the GPU error dump. Signed-off-by:

Through a twisty and circuituous path it is possible to currently trick the code into creating a default context and forgetting to pin it immediately into the GGTT. (This requires a system using contexts without an aliasing ppgtt, which is currently restricted to Baytrails machines manually specifying a module parameter to force enable contexts, or on Sandybridge and later that manually disable the aliasing ppgtt.) The consequence is that during module unload we attempt to unpin the default context twice and encounter a BUG remonstrating that we attempt to unpin an unbound object.

Having a 4 byte register at 0x321b seems unlikely as that's not 4 byte aligned. Since later platforms have more or less the same FBC registers with new names, assume that FBC_FENCE_OFF is at 0x3218 just like DPFC_FENCE_YOFF. This feels like a simple typo in BSpec. 321Bh looks a lot like 3218h after all. Should still be tested on real hardware of course. But I don't have any mobile gen4 systems. Signed-off-by:

We will anyway re-enable FBC normally after resume, so trying to save and restore the register makes little sense. We do need to preserve the FBC1 interval bits in FBC_CONTROL since we only initialize them during driver load, and try to preserve them after that. v2: s/I915_HAS_FBC/HAS_FBC/ and fix the check for gen4 Signed-off-by:

The ILK/SNB docs don't really mention the the DPFC_HT_MODIFY bit. CTG docs clearly state that it should be set only when tracking back buffer modification in persistent mode. The bit is supposed to be set by software after the first CPU modification to the back buffer, and it would get automagically cleared by the hardware on the next page flip. Since we only track front buffer modification we don't need to set this bit. GTT modification tracking still appears to work on ILK and SNB with the bit unset. I don't have a CTG to verify how that behaves. Signed-off-by:

Ville Syrjälä authored
The ILK/SNB docs are a bit unclear what the persistent mode does, but the CTG docs clearly state that it was meant to be used when we're tracking back buffer modifications. We never do that, so leave it in non-persistent mode. Signed-off-by:

Currently we print all pipe underruns on GMCH platforms. Hook up the same logic we use on PCH platforms where we disable the underrun reporting after the first underrun. Underruns don't actually generate interrupts themselves on GMCH platforms, we just can detect them whenever we service other interrupts. So we don't have any enable bits to worry about. We just need to remember to clear the underrun status when enabling underrun reporting. Note that the underrun handling needs to be moved to the non-locked pipe_stats[] loop in the interrupt handlers to avoid having to rework the locking in intel_set_cpu_fifo_underrun_reporting().

Currently we're doing the reset handling a bit late, and we're doing it both in the driver load code and on resume. This makes it unusable for e.g. resetting the panel power sequence state like Paulo wants to. Instead of adding yet another single-use callback shuffle things around: - Output handling code is responsible to reset/init all state on its own at driver load time. - We call the reset functions much earlier, before we start using any of the modeset code. Compared to Paulo's new ->resume callback the only difference in placement is that ->reset is still called without dev->struct_mutex held. Which is imo a feature. v2: Rebase on top of the now merge dinq. Cc: Paulo Zanoni <przanoni@gmail.com> Reviewed-by:

Because we already do the wait in software: see ironlake_wait_backlight_on and ironlake_edp_wait_backlight_off. For the "backlight on" delay, even BSpec says we need to program 0x1 to PP_ON_DELAYS 12:0. For the "backlight off" delay, if we don't do the same thing, when we call ironlake_wait_panel_off we'll end up waiting for the it again. On my machine the off delay is 200ms, so we save this amount of time whenever we disable the panel (e.g, suspend). Signed-off-by:
