We'll need to disable/re-enable the display-side IRQs when turning off/on the VLV display power well. Factor out the helper functions for this. For now keep the display IRQs enabled by default, so the functionality doesn't change. This will be changed to enable/disable the IRQs on-demand when adding support for VLV power wells in an upcoming patch. v2: - take the irq spin lock for the whole enable/disable sequence as these can be called with interrupts enabled Signed-off-by: NImre Deak <imre.deak@intel.com> Reviewed-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

Since the encoder is tied to its port, we need to make sure the power domain for that port is on before reading out the encoder HW state.

Parts that poke port specific HW blocks like the encoder HW state readout or connector hotplug detect code need a way to check whether required power domains are on or enable/disable these. For this purpose add a set of power domains that refer to the port HW blocks. Get the proper port power domains during modeset. For now when requesting the power domain for a DDI port get it for a 4 lane configuration. This can be optimized later to request only the 2 lane power domain, when proper support is added on the VLV PHY side for this. Atm, the PHY setup code assumes a 4 lane config in all cases.

Split the 'set' power well handler into an 'enable', 'disable' and 'sync_hw' handler. This maps more conveniently to higher level operations, for example it allows us to push the hsw package c8 handling into the corresponding hsw/bdw enable/disable handlers and the hsw BIOS hand-over setting into the hsw/bdw sync_hw handler.

Whenever we request a power domain it has to guarantee that all HW resources are enabled that are needed to access a HW register associated with that power domain. In case a register is on an always-on power well this won't result in turning on a power well, but it may require enabling some other HW resource. One such resource is the HSW/BDW device D0 state that is required for all register accesses and thus for all power wells/power domains. So far the init power domain (guaranteeing access to all HW registers) was part of the default i9xx always-on power well, but not the HSW/BDW always-on power wells. Add the domain to the latter power wells too. Atm, all the always-on power wells have noop handlers, so this doesn't change the functionality. v2: - clarify semantics of always-on power wells (Paulo) Signed-off-by: NImre Deak <imre.deak@intel.com> Reviewed-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

There are too many oustanding issues: - Fence handling in the current code is broken. There's a patch series from me, but it's blocked on and extended review (which includes writing the testcases). - IOMMU mapping handling is broken, we need to properly refcount it - currently it gets destroyed when the first vma is unbound, so way too early. - There's a pending reset issue on snb. Since Mika's reset work and full ppgtt have been pulled in in separate branches and ended up intermittingly breaking each another it's unclear who's the exact culprit here. - We still have persistent evidince of crazy recursion bugs through vma_unbind and ppgtt_relase, e.g. https://bugs.freedesktop.org/show_bug.cgi?id=73383 This issue (and a few others meanwhile resolved) have blocked our performance measuring/tuning group since 3 months. - Secure batch dispatching is broken. This is blocking Brad Volkin's command checker work since 3 months. All these issues are confirmed to only happen when full ppgtt is enabled, falling back to aliasing ppgtt resolves them. But even aliasing ppgtt itself still has a regression: - We currently unconditionally bind objects into the aliasing ppgtt, which means all priviledged objects like ringbuffers are visible to unpriviledged access again. On top of that this also breaks the command checker for aliasing ppgtt, since it can't hide the validated batch any more. Furthermore topic/full-ppgtt has never been reviewed: - Lifetime rules around vma unbinding/release are unclear, resulting into this awesome hack called ppgtt_release. Which seems to take the blame for most of the recursion fallout. - Context/ring init works different on gpu reset than anywhere else. Such differeneces have in the past always lead to really hard to track down bugs. - Aliasing ppgtt is treated in a bunch of places as a real address space, but it isn't - the real address space is always the global gtt in that case. This results in a bit a mess between contexts and ppgtt object, further complication the context/ppgtt/vma lifetime rules. - We don't have any docs describing the overall concepts introduced with full ppgtt. A short, concise overview describing vmas and some of the strange bits around them (like the unbound vmas used by execbuf, or the new binding rules) really is needed. Note that a lot of the post topic/full-ppgtt merge fallout has already been addressed, this entire list here of 10 issues really only contains the still outstanding issues. Finally the 3.15 merge window is approaching and I think we need to use the remaining time to ensure that our fallback option of using aliasing ppgtt is in solid shape. Hence I think it's time to throw the switch. While at it demote the helper from static inline status because really.

On DDI there's no PLL as such to generate the pixel clock for VGA. Instead we derive the pixel clock from the FDI link frequency. So to make .compute_config match what .get_config does, we need to set the port_clock based on the FDI link frequency. Note that we don't even check the port_clock when selecting the PLL for VGA output. We just assume SPLL at 1.35GHz is what we want, and that does match with the asumption of FDI frequency of 2.7Ghz we have in intel_fdi_link_freq().
