Note that a later patch will use these functions in some other file and drop the static. Hence the kerneldoc looks appropriate. 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: -

This shouldn't change the behavior of those functions, since they are called after the new_config is made effective and that points to the current config. In a follow up patch, the mode set sequence will be changed so this is called before disabling crtcs, and in that case those functions should work on the staged config. Signed-off-by:

execlists_submit_context() always returns 0, which is redundant. And its name is inaccurate, since it actually submits (up to) TWO contextS. So we rename it, change it to "void", and remove the WARN_ON() testing its return value. Change-Id: Ie225b0eca7754c6093c8b8bd15550b251b6feb82 Signed-off-by:

If a ring failed to initialise for any reason then the error path would try to clean up all rings including those that had not yet been allocated. The ring clean up code did a check that the ring was valid before starting its work. Unfortunately, that was after it had already dereferenced the ring to obtain a dev_private pointer. Signed-off-by:

When looking at the bug report logs with triggered WARN_ON, the person doing bug triaging will have to find exact kernel source and match file/line. Attach the condition that triggered the WARN_ON to kernel log. In most cases the context is self evident and this way we can save developer time. The drawback is ~16kbytes bigger i915.ko Signed-off-by:

When we suspend we turn everything off so the pps should be idle, and we also (or at least should) disable all power wells which will reset the power sequencer port assignment. So when we resume all power sequencers should be in their reset state. However it's at least theoretically possible that the BIOS would touch the power seuqencer(s), so to be safe we ought to read out the current port assignment like we do at driver init time. To do that we can simply call vlv_initial_power_sequencer_setup() from the encoder ->reset() hook before calling intel_edp_panel_vdd_sanitize(). There's no danger or clobbering the pps delays since we now have those stored within intel_dp and we don't change them once initialized. This will make sure that the vdd state gets correctly tracked post-resume in case the BIOS enabled it. We need to shuffle things around a bit to get the locking right, and while at it, make intel_edp_panel_vdd_sanitize() static and move it around a bit to avoid a forward declaration.
