Once upon a time before we had automated GPU state capture upon hangs, we had intel_gpu_dump. Now we come almost full circle and reinstate that view of the current GPU queues and registers by using the error capture facility to snapshot the GPU state when debugfs/.../i915_gpu_info is opened - which should provided useful debugging to both the error capture routines (without having to cause a hang and avoid the error state being eaten by igt) and generally. v2: Rename drm_i915_error_state to i915_gpu_state to alleviate some name collisions between the error state dump and inspecting the gpu state.

We currently capture the GPU state after we detect a hang. This is vital for us to both triage and debug hangs in the wild (post-mortem debugging). However, it comes at the cost of running some potentially dangerous code (since it has to make very few assumption about the state of the driver) that is quite resource intensive. This patch introduces both a method to disable error capture at runtime (for users who hit bugs at runtime and need a workaround) and to disable error capture at compiletime (for realtime users who want to minimise any possible latency, and never require error capture, saving ~30k of code). The cost is that we now have to be wary of (and test!) a kconfig flag and a module parameter. The effect of the module parameter is easy to verify through code inspection and runtime testing, but a kconfig flag needs regular compile checking.

Our goal is to rename the anonymous per-engine struct beneath the current intel_context. However, after a lively debate resolving around the confusion between intel_context_engine and intel_engine_context, the realisation is that the two structs target different users. The outer struct is API / user facing, and so carries the higher level GEM information. The inner struct is hw facing. Thus we want to name the inner struct intel_context and the outer one i915_gem_context. As the first step, we need to rename the current struct: s/struct intel_context/struct i915_gem_context/ which fits much better with its constructors already conveying the i915_gem_context prefix!

The cherryview device shares many characteristics with the valleyview device. When support was added to the driver for cherryview, the corresponding device info structure included .is_valleyview = 1. This is not correct and leads to some confusion. This patch changes .is_valleyview to .is_cherryview in the cherryview device info structure and simplifies the IS_CHERRYVIEW macro. Then where appropriate, instances of IS_VALLEYVIEW are replaced with IS_VALLEYVIEW || IS_CHERRYVIEW or equivalent. v2: Use IS_VALLEYVIEW || IS_CHERRYVIEW instead of defining a new macro. Also add followup patches to fix issues discovered during the first review. (Ville) v3: Fix some style issues and one gen check. Remove CRT related changes as CRT is not supported on CHV.

Make I915_READ and I915_WRITE more type safe by wrapping the register offset in a struct. This should eliminate most of the fumbles we've had with misplaced parens. This only takes care of normal mmio registers. We could extend the idea to other register types and define each with its own struct. That way you wouldn't be able to accidentally pass the wrong thing to a specific register access function. The gpio_reg setup is probably the ugliest thing left. But I figure I'd just leave it for now, and wait for some divine inspiration to strike before making it nice. As for the generated code, it's actually a bit better sometimes. Eg. looking at i915_irq_handler(), we can see the following change: lea 0x70024(%rdx,%rax,1),%r9d mov $0x1,%edx - movslq %r9d,%r9 - mov %r9,%rsi - mov %r9,-0x58(%rbp) - callq *0xd8(%rbx) + mov %r9d,%esi + mov %r9d,-0x48(%rbp) callq *0xd8(%rbx) So previously gcc thought the register offset might be signed and decided to sign extend it, just in case. The rest appears to be mostly just minor shuffling of instructions. v2: i915_mmio_reg_{offset,equal,valid}() helpers added s/_REG/_MMIO/ in the register defines mo more switch statements left to worry about ring_emit stuff got sorted in a prep patch cmd parser, lrc context and w/a batch buildup also in prep patch vgpu stuff cleaned up and moved to a prep patch all other unrelated changes split out v3: Rebased due to BXT DSI/BLC, MOCS, etc. v4: Rebased due to churn, s/i915_mmio_reg_t/i915_reg_t/ Signed-off-by: NVille Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: NChris Wilson <chris@chris-wilson.co.uk> Link: http://patchwork.freedesktop.org/patch/msgid/1447853606-2751-1-git-send-email-ville.syrjala@linux.intel.com

Currently we don't call valleyview_set_rps() when changing the min/max limits through sysfs if the current frequency is still within the new limits. However that means we sometimes forget to update PMINTRMSK. Eg. if the current frequency is at the old minimum, and then we reduce the minum further we should then enable the 'down' interrupts in PMINTRMSK but currently we don't. Fix it up by always calling valleyview_set_rps() (just like we do for !vlv/chv platforms). This also allows the code to be simplified a bit.

On VLV/CHV the rc6 residency calculations read a second register to determine the actual units used for the residency value. The variable name 'reg' where that register value is stored shadows the function argument 'reg'. That can easily leave the reader utterly confused, so rename the internal variable to 'clk_reg'.

We don't register the rc6p and rc6pp sysfs files on VLV, so there's no point in having any VLV checks in them. Drop the checks.

Avoid to expose RC6 and RC6pp to the platforms that doesn't support it. So powertop can be changed to show RC6p and RC6pp only on the platforms they are available. v2: Simplify by merging RC6p and RC6pp groups and respect the spec that mentions deep and deepest RC6 on SNB and IVB although they keep disabled by default. v3: Remove unecessary space. v4: RC6p and RC6pp is only for SNB and IVB; unify debug msg and use has_rc6p() on sanitize options instead of is gen 6 and ivb. v5: yet another fix on has_rc6p macro. final is_gen6 or is_ivb! To make sure we are excluding hsw and baytrail.

The register to read cz count is different from vlv. Also the counts returned from CCK_CTL1 for BSW are (ticks in 30ns - 1). czcount_30ns of value 1 is a special case for 320Mhz.

Up until now, contexts had one (and only one) backing object that was used by the hardware to save/restore render ring contexts (via the MI_SET_CONTEXT command). Other rings did not have or need this, so our i915_hw_context struct had a 1:1 relationship with a a real HW context. With Logical Ring Contexts and Execlists, this is not possible anymore: all rings need a backing object, and it cannot be reused. To prepare for that, rename our contexts to the more generic term intel_context. No functional changes.
