Add 'u32 offset' to the uncore register access functions. For now it's the same as 'reg', but once type safety gets added 'reg' will be the type safe register variable and 'offset' the raw offset. v2: s/uint32_t/u32/ (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1446839236-20035-1-git-send-email-ville.syrjala@linux.intel.comReviewed-by: Chris Wilson <chris@chris-wilson.co.uk>

We'll want to avoid performing arithmetic with register offsets, so instead calculating the vgpu PDP as pdp0_lo+offset, make the PDPs into an array. This way we can simply loop through them.

Most of our register defines follow the convention that if there's a need for the raw register offset, that one has an underscore sa a prefix. The define (possibly parametrized) without the underscore is the one people should normally use, since it will take into account all the parameters and other potential offsets that are needed. Fix up the few stragglers that don't follow this convention.

If we ignore the BXT situation, we can observe that the only variables affecting gpio_mmio_base is IS_VALLEVIEW and HAS_GMCH_DISPLAY. The BXT situation we can fit into the same pattern if we change gmbus_pins_bxt[] to house the GMCH GPIO register offsets (like we do for all other platfotms). So let's do that. We could even simplify the VLV situation more by including the display_mmio_offset in the GPIO register defines, but let's leave it be for now.

i915 register defines are going to become type safe, so going forward the register defines can't be used as straight numbers. Since quirks.c needs just a few extra register defines from i915_reg.h, decouple the two by defining the required registers locally in quirks.c. This was already done for a few other igpu related registers.

It was created at 'commit aabc95dc (drm/i915: Dont -ETIMEDOUT on identical new and previous (count, crc).")' becase the counter wasn't reliable. Now that we properly wait for the counter to be reset we can rely a bit more in the counter. Also that patch stopped to return -ETIMEDOUT so the test case is unable to skip when it is unreliable and end up in many fails that should be skip instead. So, with the counter more reliable we can remove this hack that just makes things more confusing when test cases are really expecting the same CRC and let test case skip if that's not the case.

Currently the gmbus code uses intel_aux_display_runtime_get/put in an effort to make sure the hardware is powered up sufficiently for gmbus. That function only takes the runtime PM reference which on VLV/CHV/BXT is not enough. We need the disp2d/pipe-a well on VLV/CHV and power well 2 on BXT. So add a new power domnain for gmbus and kill off the now unused intel_aux_display_runtime_get/put. And change intel_hdmi_set_edid() to use the gmbus power domain too since that's all we need there. Also toss in a BUILD_BUG_ON() to catch problems if we run out of bits for power domains. We're already really close to the limit...

Introduce intel_display_port_aux_power_domain() which simply returns the appropriate AUX power domain for a specific port, and then replace the intel_display_port_power_domain() with calls to the new function in the DP code. As long as we're not actually enabling the port we don't need the lane power domains, and those are handled now purely from modeset_update_crtc_power_domains(). My initial motivation for this was to see if I could keep the DPIO power wells powered down while doing AUX on CHV, but turns out I can't so this doesn't change anything for CHV at least. But I think it's still a worthwile change. v2: Add case for PORT E. Default to POWER_DOMAIN_AUX_D for now.

When this option is 0 (so the power well support is disabled) we are supposed to enable all power wells once and don't disable them unless we system suspend the device. Currently if the option is 0, we can call the power well enable handlers multiple times, whenever their refcount changes from 0->1. This may not be a problem for the HW, but it's not logical and may trigger some warnings in the power well code which doesn't expect this. So simply keep around a reference while we are not system suspended to solve this. For simplicity mark the module option read only, so we don't need to deal with re-enabling the feature during runtime. If someone really needs that it could be added later in a more proper way. v2: - fix typo in comment in intel_power_domains_suspend() (Patrik) Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Patrik Jakobsson <patrik.jakobsson@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1447775063-24438-1-git-send-email-imre.deak@intel.com
