Belongs in PCH enable instead. The duplication is worrying and the specs explicitly list transcoder select *after* actual PLL enable, which doesn't occur until later.

At the point where we check, we can't do much about the failure, but it can aid debugging. Note that the auto-train override bit will be reset as part of normal mode setting with this patch if a pipe ever does get stuck, but that's consistent with the workaround for CPT provided by the hardware team. This patch helped catch the fact that the pipe wasn't running in the !composite sync FDI case on my IVB SDV, so has already shown to be useful.

Add two new fields to the intel_crtc struct for 3 pipe support: no_pll and use_pll_a. The no_pll field is only set on the 3rd pipe to indicate that it doesn't have a PLL of its own and so shouldn't try to write the main PLL regs. The use_pll_a field controls which PLL pipe 3 will share, A or B. The core code will try to share PLLs with whichever pipe has the same timings, rejecting the mode set if none is found. This means that pipe 3 must always be set after one of the other pipes has been configured with real PLL settings.

Well almost anyway. IVB has 3 planes, pipes, transcoders, and FDI interfaces, but only 2 pipe PLLs. So two of the pipes must use the same pipe timings (e.g. 2 DP plus one other, or two HDMI with the same mode and one other, etc.).

[Description from: Daniel Vetter] I've just discussed this quickly with Chris on irc and it's probably best to just kill the list_empty early bailout. gpu_idle isn't a fastpath, so who cares. One candidate where we emit commands to the ring without adding anything onto these lists is e.g. pageflip. There are probably more.

We really don't want this to work in the general case; device drivers *shouldn't* care whether they are behind an IOMMU or not. But the integrated graphics is a special case, because the IOMMU and the GTT are all kind of smashed into one and generally horrifically buggy, so it's reasonable for the graphics driver to want to know when the IOMMU is active for the graphics hardware.

To work around a hardware issue, we have to submit IOTLB flushes while the graphics engine is idle. The graphics driver will (we hope) go to great lengths to ensure that it gets that right on the affected chipset(s)... so let's not screw it over by deferring the unmap and doing it later.

For the !HAVE_ATOMIC_IOMAP case the stub functions did not call pagefault_disable/_enable. The i915 driver relies on the map actually being atomic, otherwise it can deadlock with it's own pagefault handler in the gtt pwrite fastpath. This is exercised by gem_mmap_gtt from the intel-gpu-toosl gem testsuite. v2: Chris Wilson noted the lack of an include.

This patch closes the following race: We get a PM interrupt A, mask it, set dev_priv->iir = PM_A and kick of the work item. Scheduler isn't grumpy, so the work queue takes rps_lock, grabs pm_iir = dev_priv->pm_iir and pm_imr = READ(PMIMR). Note that pm_imr == pm_iir because we've just masked the interrupt we've got. Now hw sends out PM interrupt B (not masked), we process it and mask it. Later on the irq handler also clears PMIIR. Then the work item proceeds and at the end clears PMIMR. Because (local) pm_imr == pm_iir we have pm_imr & ~pm_iir == 0 so all interrupts are enabled. Hardware is still interrupt-happy, and sends out a new PM interrupt B. PMIMR doesn't mask B (it does not mask anything), PMIIR is cleared, so we get it and hit the WARN in the interrupt handler (because dev_priv->pm_iir == PM_B). That's why I've moved the WRITE(PMIMR, 0) up under the protection of the rps_lock. And write an uncoditional 0 to PMIMR, because that's what we'll do anyway. This races looks much more likely because we can arbitrarily extend the window by grabing dev->struct mutex right after the irq handler has processed the first PM_B interrupt.

Quoting Chris Wilson's more concise description: "Ah I think I see the problem. As you point out we only mask the current interrupt received, so that if we have a task pending (and so IMR != 0) we actually unmask the pending interrupt and so could receive it again before the tasklet is finally kicked off by the grumpy scheduler." We need the hw to issue PM interrupts A, B, A while the scheduler is hating us and refuses to run the rps work item. On receiving PM interrupt A we hit the WARN because dev_priv->pm_iir == PM_A | PM_B Also add a posting read as suggested by Chris to ensure proper ordering of the writes to PMIMR and PMIIR. Just in case somebody weakens write ordering.

There's no good reason to turn off the eDP force VDD bit synchronously while probing devices; that just sticks a huge delay into all mode setting paths. Instead, queue a delayed work proc to disable the VDD force bit and then remember when that fires to ensure that the appropriate delay is respected before trying to turn it back on.
