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). As for the is_initialized flag, we only use to signify that the render state has been initialized (a.k.a. golden context, a.k.a. null context). It doesn't mean anything for the other engines, so make that distinction obvious.
