This patch reads the memory latency values for all the 8 levels for SKL. These values are needed for the Watermark computation. v2: Incorporated the review comments from Damien on register indentation. v3: Updated the code to use the sandybridge_pcode_read for reading memory latencies for GEN9. v4: Don't put gen 9 in the middle of an ordered list of ifs (Damien) v5: take the rps.hw_lock around sandybridge_pcode_read() (Damien) v6: Use gen >= 9 in the pcode_read() function for data1. Move the defines near the gen6 ones and prefix them with PCODE. Remove unused timeout define (the pcode_read() code has a larger timeout already).

There's some serious confusion regarding ELD valid bit that gets set and cleared back and forth etc. Rewrite it all based on the documented audio codec enable/disable sequences. v3: replace vblank wait with a comment v4: expand the comment on what should be done with the vblank wait Signed-off-by:

Make audio related register defines conform to existing style: Add _MASK where relevant, indent the defines for register contents, don't indent the defines for register addresses, prefix pipe specific register address defines with underscores, drop self explanatory comments. No functional changes. Signed-off-by:

Userspace cares about whether or not swizzling depends on the page address for its direct access into bound objects. Extend the get_tiling ioctl to report the physical swizzling value in addition to the logical swizzling value so that userspace can accurately determine when it is possible for manual detiling.

Always require PIN_GLOBAL when we want a mappable offset (PIN_MAPPABLE). This causes the pin to fixup the global binding in cases were the vma was already bound (and due to the proceeding bug, we considered it to be already mappable).

We use the obj->map_and_fenceable hint for when we already have a valid mapping of this object in the aperture. This hint can only apply to the GGTT and not to the aliasing-ppGTT. One user of the hint is execbuffer relocation, which began to fail when it tried to follow the hint and perform the relocate through the non-existent GGTT mapping.

Currently we program just DPSCNTR and DSPSTRIDE directly from the ring interrupt handler, which is fine since the hardware guarantees that those are update atomically. When we have atomic page flips we'll want to be able to update also the offset registers, and then we need to use the vblank evade mechanism to guarantee atomicity. Since that mechanism introduces a wait, we need to do the actual register write from a work when it is triggered by the ring interrupt. v2: Explain the need for mmio_flip.work in the commit message (Paulo) Initialize the mmio_flip work in intel_crtc_init() (Paulo) Prevent new flips the previous flip work finishes (Paulo) Don't acquire modeset locks for mmio flip work Note: Paulo had reservations about the work item leaking over a plane disable. But insofar as we do lack these checks that issue is already present with the existing code. Signed-off-by:Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reviewed-by:

A follow up patch will call this funcion from a work context for the mmio flip, in which case we cannot acquire the modeset locks. That's not a problem though, since the check is there to protect vblank and the mode, but the code that changes that waits for pending flips first. Signed-off-by:

An earlier commit (c8725f3d: Do not call retire_requests from wait_for_rendering) removed the use of the ring parameter within wait_rendering__tail() but did not remove the parameter itself. As the plan is to remove obj->ring which is where this parameter comes from, it is simpler to just remove the parameter completely than to update it with a new source. For: VIZ-4377 Signed-off-by:

With this patch, the RPS sequence for runtime suspend/resume is exactly like the sequence for S3 suspend/resume: - flush_delayed_work(&dev_priv->rps.delayed_resume_work) - intel_runtime_pm_disable_interrupts() - intel_suspend_gt_powersave() (suspended) - intel_runtime_pm_enable_interrupts() - intel_enable_gt_powersave() With this, we get rid of WARNs that are currently intermittently triggered by the system-suspend-execbuf subtest of runtime PM. Notice that these WARNs could also be triggered in other ways that involved doing lots of RPM suspend/resume cycles just after a system S3 resume.

The extra VLV_IIR writes at the end of vlv_display_irq_postinstall() serve no purpose. Remove them. The VLV_IMR/IER/IIR setup at the start of the function also seems a bit pointless since it doesn't unmask/enable anything. But leave it be for now. Signed-off-by:

When disabling interrupts we do the writes in this order: IMR,IER,IIR,IIR. But when enabling interrupts we don't do use the mirrored order, and instead do IIR,IIR,IMR,IER. I like consistency unless there's a good reason against it, which I can't think of here, so change the enable order to IIR,IIR,IER,IMR. Signed-off-by:

On pre-ddi platforms we don't shut down the link when changing link training parameters. Except when clock recovery fails too hard and we restart with channel eq training. Which doesn't make a lot of sense really, since just stopping/restarting the DP port at this point violates the modeset sequence documented in the Bspec. So let's tempt fate and try this.

It's really part of the "push all new_* state into current state pointers" done in that function. So let's move it there to make this clear. Also, with the conversion done the num_shared_dpll check the function does in it's loop is enough, so we can drop the check for the dpll compute callback, too.

Ander Conselvan de Oliveira authored
It is possible for a mode set to fail if there aren't shared DPLLS that match the new configuration requirement or other errors in clock computation. If that step is executed after disabling crtcs, in the failure case the hardware configuration is changed and needs to be restored. Doing those things early will allow the mode set to fail before actually touching the hardware. Follow up patches will convert different platforms to use the new infrastructure. v2: Keep pll->new_config valid only during mode set (Ville) Use kmemdup() in i915_shared_dpll_start_config() (Ville) Restore old pll config if something fails before commit (Ville) Don't set compute_clock hooks since dev_priv is kzalloc()'d (Ville) Signed-off-by: -
