This adds support for a default of 4 heads, with a command line parameter to change the default number. It also overhauls the modesetting code to handle this case properly, and send the correct things to the hardware at the right time. Signed-off-by:Dave Airlie <airlied@redhat.com>

There are missing parts to handle error in drm_open_helper(). The priv->minor, assigned by idr_find() which can return NULL, should be checked whether it is NULL or not before referencing it. put_pid(), drm_gem_release(), and drm_prime_destory_file_private() should be called when error happens after their pair functions are called. If an error occurs after executing dev->driver->open() which allocates driver specific per-file private data, then the private data should be released. Signed-off-by:

If raw_edid of drm_edid_block_vaild() is null, it will crash, so checking in bad label is removed and instead assertion is added at the top of the function. The type of return for the function is bool, so it fixes to return true and false instead of 1 and 0. Signed-off-by:

Convert drivers/gpu/drm class to use dev_pm_ops for power management and remove Legacy PM ops hooks. With this change, drm class registers suspend/resume callbacks via class->pm (dev_pm_ops) instead of Legacy class->suspend/resume. When __device_suspend() runs call-backs, it will find class->pm ops for the drm class. drm_class_suspend() hook calls driver legacy ops with the state information. e.g: drm_class_suspend() calls into driver suspend routines via drm_dev->driver->suspend(drm_dev, state). Once drm_class_suspend() is converted to dev_pm_ops, it will no longer have access to pm_transition which it has to pass into driver legacy suspend calls. A new freeze and suspend hooks are added to address the not having access to the state information. The new freeze and suspend hooks simply call __drm_class_suspend() with the appropriate pm state information. __drm_class_suspend() is the original suspend hook with a new name. Signed-off-by:

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).
