Merge tag 'drm-intel-fixes-2013-07-03' of git://people.freedesktop.org/~danvet/drm-intel into drm-next Pile of fixes for 3.11. A bit large in patch count, but that's simply due to two fixes being split up into really small parts. Also I've included a few more vlv patches than I'd have included for other platforms. But since vlv is officially supported for the first time only in 3.11 that shouldn't result in unbearable risks. Highlights: - ghost eDP fixes for hsw from Paulo - fix PCH detection in virtualized enviroments (Rui Guo) - duct-tape dma sg construction when swiotlb is in use (Konrad), dupe with a patch in your drm-fixes branch - fix sdvo hotplug on i965g - tune down a bunch of dmesg ERRORs which can be hit under normal conditions - detect invalid pitches for tiled scanout buffers (Chris) - a pile of vlv fixes from Ville: rps improvements, fixes for the dpll LPF, fixup the sprite mmio offsets - fix context size on hsw (Ben) - locking fixes for the hotplug code, specifically the storm handling - fix get_config on CPT (Xiong Zhang) - Fix the domain tracking when an unlocked seqno wait was interrupt (Chris), this seems to explain tons of little corruption bugs in the ddx. Chris also added a nice igt to exercise this. - work around stack-corrupting vnsprintf in our error state dumper * tag 'drm-intel-fixes-2013-07-03' of git://people.freedesktop.org/~danvet/drm-intel: (39 commits) drm/i915: Don't try to tear down the stolen drm_mm if it's not there drm/i915: Break up the large vsnprintf() in print_error_buffers() drm/i915: Refactor the wait_rendering completion into a common routine drm/i915: Only clear write-domains after a successful wait-seqno drm/i915: correct intel_dp_get_config() function for DevCPT drm/i915: fix hpd interrupt register locking drm/i915: fold the no-irq check into intel_hpd_irq_handler drm/i915: fold the queue_work into intel_hpd_irq_handler drm/i915: fold the hpd_irq_setup call into intel_hpd_irq_handler drm/i915: s/hotplug_irq_storm_detect/intel_hpd_irq_handler/ drm/i915: close tiny race in the ilk pcu even interrupt setup drm/i915: fix locking around ironlake_enable|disable_display_irq drm/i915: Fix context sizes on HSW drm/i915: Fix VLV sprite register offsets Revert "drm/i915: Don't use the HDMI port color range bit on Valleyview" drm/i915: s/LFP/LPF in DPIO PLL register names drm/i915: Fix VLV PLL LPF coefficients for DAC drm/i915: Jump to at least RPe on VLV when increasing the GPU frequency drm/i915: Don't increase the GPU frequency from the delayed VLV rps timer drm/i915: GEN6_RP_INTERRUPT_LIMITS doesn't seem to exist on VLV ...

Every other place properly checks whether we've managed to set up the stolen allocator at boot-up properly, with the exception of the cleanup code. Which results in an ugly *ERROR* Memory manager not clean. Delaying takedown at module unload time since the drm_mm isn't initialized at all. v2: While at it check whether the stolen drm_mm is initialized instead of the more obscure stolen_base == 0 check. v3: Fix up the logic. Also we need to keep the stolen_base check in i915_gem_object_create_stolen_for_preallocated since that can be called before stolen memory is fully set up. Spotted by Chris Wilson. v4: Readd the conversion in i915_gem_object_create_stolen_for_preallocated, the check is for the dev_priv->mm.gtt_space drm_mm, the stolen allocatot must already be initialized when calling that function (if we indeed have stolen memory).

So it appears that I have encountered some bogosity when trying to call i915_error_printf() with many arguments from print_error_buffers(). The symptom is that the vsnprintf parser tries to interpret an integer arg as a character string, the resulting OOPS indicating stack corruption. Replacing the single call with its 13 format specifiers and arguments with multiple calls to i915_error_printf() worked fine. This patch goes one step further and introduced i915_error_puts() to pass the strings simply. It may not fix the root cause, but it does prevent my box from dying and I think helps make print_error_buffers() more friendly. Signed-off-by:

Harmonise the completion logic between the non-blocking and normal wait_rendering paths, and move that logic into a common function. In the process, we note that the last_write_seqno is by definition the earlier of the two read/write seqnos and so all successful waits will have passed the last_write_seqno. Therefore we can unconditionally clear the write seqno and its domains in the completion logic. v2: Add the missing ring parameter, because sometimes it is good to have things compile. Signed-off-by:

In the introduction of the non-blocking wait, I cut'n'pasted the wait completion code from normal locked path. Unfortunately, this neglected that the normal path returned early if the wait returned early. The result is that read-only waits may return whilst the GPU is still writing to the bo.

Our interrupt handler (in hardirq context) could race with the timer (in softirq context), hence we need to hold the spinlock around the call to ->hdp_irq_setup in intel_hpd_irq_handler, too. But as an optimization (and more so to clarify things) we don't need to do the irqsave/restore dance in the hardirq context. Note also that on ilk+ the race isn't just against the hotplug reenable timer, but also against the fifo underrun reporting. That one also modifies the SDEIMR register (again protected by the same dev_priv->irq_lock). To lock things down again sprinkle a assert_spin_locked. But exclude the functions touching SDEIMR for now, I want to extract them all into a new helper function (like we do already for pipestate, display interrupts and all the various gt interrupts). v2: Add the missing 't' Egbert spotted in a comment. v3: Actually fix the right misspelled comment (Paulo).

The combination of Paulo's fifo underrun detection code and Egbert's hpd storm handling code unfortunately made the hpd storm handling code racy. To avoid duplicating tricky interrupt locking code over all platforms start with a bit of refactoring. This patch is the very first step since in the end the irq storm handling code will handle all hotplug logic (and so also encapsulate the locking nicely). v2: Rebase on top of the i965g/gm sdvo hpd fix.

By the time we write DEIER in the postinstall hook the interrupt handler could run any time. And it does modify DEIER to handle interrupts. Hence the DEIER read-modify-write cycle for enabling the PCU event source is racy. Close this races the same way we handle vblank interrupts: Unconditionally enable the interrupt in the IER register, but conditionally mask it in IMR. The later poses no such race since the interrupt handler does not touch DEIMR. Also update the comment, the clearing has already happened unconditionally above. v2: Actually shove the updated comment into the right train^W commit, as spotted by Paulo.

The haswell unclaimed register handling code forgot to take the spinlock. Since this is in the context of the non-rentrant interupt handler and we only have one interrupt handler it is sufficient to just grab the spinlock - we do not need to exclude any other interrupts from running on the same cpu. To prevent such gaffles in the future sprinkle assert_spin_locked over these functions. Unfornately this requires us to hold the spinlock in the ironlake postinstall hook where it is not strictly required: Currently that is run in single-threaded context and with userspace exlcuded from running concurrent ioctls. Add a comment explaining this. v2: ivb_can_enable_err_int also needs to be protected by the spinlock. To ensure this won't happen in the future again also sprinkle a spinlock assert in there. v3: Kill the 2nd call to ivb_can_enable_err_int I've accidentally left behind, spotted by Paulo.

With updates to the spec, we can actually see the context layout, and how many dwords are allocated. That table suggests we need 70720 bytes per HW context. Rounded up, this is 18 pages. Looking at what lives after the current 4 pages we use, I can't see too much important (mostly it's d3d related), but there are a couple of things which look scary. I am hopeful this can explain some of our odd HSW failures. v2: Make the context only 17 pages. The power context space isn't used ever, and execlists aren't used in our driver, making the actual total 66944 bytes. v3: Add a comment to the code. (Jesse & Paulo) Reported-by:
