This time around another cute hack to pre-fill the pll->hw_state with the right values. And also remove a bunch of checks which will be replaced by lots more checks in the common framework.

Currently still with a redudant WARN_ON in there, the common shared dpll code will take care of this in the future. Also we need to flip the switch for the transitional hack now to make sure that we disable the right pll.

Just filing in names and ids, but not yet officially registering them so that the hw state cross checker doesn't completely freak out about them. Still since we do already read out and cross check config->shared_dpll the basics are now there to flesh out the wrpll shared dpll implementation. The idea is now to roll out all the callbacks step-by-step and then at the end switch to the shared dpll framework. This way hw and sw changes are clearly separated.

To make things a bit more manageable extract a new function for reading out common ddi port state. This means a bit of duplication between encoders and the core since both look at the same registers, but doesn't seem worth to make a fuzz about. We can also remove the state readout code in intel_ddi_setup_hw_pll_state. That code is only called from the hardware take over and not the cross check code, and only after the crtc state is reconstructed. So we can rely on an accurate value of crtc->config.ddi_pll_sel already. Compared to the old code also trust the hw state more and don't special-case port A - we want to cross-check the actual-state, not bake in our own assumptions about how this is supposed to all be linked up. v2: Make use of the read-out ddi_pll_sel in intel_ddi_clock_get.

Similar to how the ->crtc_mode_set hook should touch the hardware to enable anything the ->crtc_off hook should disable anything in the hardware. Otherwise runtime pm for dpms will not work. Currently the only things left int the haswell_crtc_off hook is disabling the ddi plls. We can't move the WRPLL enabling out yet because the current ddi pll sharing code used by the haswell code doesn't separately track active users and overall users. This must be fixed by porting it to the generic shared display pll framework, which is powerful enough. But the SPLL source is only used by the crt encoder and so can be moved already. We only need to make sure that the ddi port E is already off, which hsw_fdi_disable does by calling intel_ddi_post_disable. With this the code reorg to shuffle hsw fdi/lpt specific code into a new hsw-specific crt encoder type is now finally complete.

The call to intel_ddi_pll_enable in haswell_crtc_mode_set is the only function that still touches the hardware state from the crtc mode_set callback on hsw. Since the SPLL isn't ever shared we can easily take it out into the hsw crt encoder functions. Temporarily we'll loose a bit of WARN_ON coverage with this, but once the WRPLLs are switched over that will be restored. For the SPLL selection add a WARN in the hsw fdi link training code.

All the other checks also check hw state, so checking our software refcounts for the plls looks a bit odd. Also this will simplify the conversion over to the shared dpll framework, which itself has massive amounts of checks to make sure that we never leave a display pll enabled when we shouldn't. So after that conversion we should stil have a good enough coverage of asserts for entering pc8/runtime pm on hsw/bdw.

On HSW, the D_COMP register can be accessed through the mailbox (read and write) or through MMIO on a MCHBAR offset (read only). On BDW, the access should be done through MMIO on another address. So to account for all these cases, create hsw_read_dcomp() with the correct implementation for reading, and also fix hsw_write_dcomp() to do the correct thing on BDW. With this patch, we can now get back from the PC8+ state on BDW. We were previously getting a black screen and lots of dmesg errors. Please notice that the bug only happens when you actually reach the PC8+ states, not when you only allow it.

On g33, the documentation states "HWS_PGA: Format = Bits 28:12 of graphics memory address (bits 31:29 MBZ)." which translates to that the address of the HWS must be below 256MiB, which is conveniently the mappable aperture. This also appears to be true (but not documented as so) for gen4 and gen5. To generalise we force it into the low mappable region for all non-LLC platforms.

This is an Execlists preparatory patch, since they make context ID become an overloaded term: - In the software, it was used to distinguish which context userspace was trying to use. - In the BSpec, the term is used to describe the 20-bits long field the hardware uses to it to discriminate the contexts that are submitted to the ELSP and inform the driver about their current status (via Context Switch Interrupts and Context Status Buffers). Initially, I tried to make the different meanings converge, but it proved impossible: - The software ctx->id is per-filp, while the hardware one needs to be globally unique. - Also, we multiplex several backing states objects per intel_context, and all of them need unique HW IDs. - I tried adding a per-filp ID and then composing the HW context ID as: ctx->id + file_priv->id + ring->id, but the fact that the hardware only uses 20-bits means we have to artificially limit the number of filps or contexts the userspace can create.

We have already advanced that Logical Ring Contexts have their own kind of backing objects, but everything will be better explained in the Execlists series. For now, suffice it to say that the current backing object is only ever used with the render ring, so we're making this fact more explicit (which is a good reason on its own).
