A few advantages: - Prepares us for the planned split of display uncore from GT uncore - Improves our engine-centric view of the world in the engine code and allows us to avoid jumping back to dev_priv. - Allows us to wrap accesses to engine register in nice macros that automatically pick the right mmio base.

The intel_uncore structure is the owner of register access, so subclass the function to it. While at it, use a local uncore var and switch to the new read/write functions where it makes sense. Signed-off-by:

We have several cases where we don't have forcewake (older gens, GVT and planned display-only uncore), so, instead of checking every time against the various condition, save the info in a flag and use that. Note that this patch also change the behavior for gen5 with vpgu enabled, but this is not an issue since we don't support vgpu on gen5. v2: split out from previous path, fix check for missing case (Paulo) v3: Inline helper for clarity in testing flags Signed-off-by:

By the time icl_ddi_clock_get() is called we've just got the hw state from the pll registers. We don't need to read them again: we can rather reuse what was cached in the dpll_hw_state. While at it, s/refclk/ref_clock/ just to be consistent with the name used in code nearby. Signed-off-by:

By the time cnl_ddi_clock_get() is called we've just got the hw state from the pll registers. We don't need to read them again: we can rather reuse what was cached in the dpll_hw_state. This also affects the code for ICL since it partially reuses the CNL code. However the more intricate part on ICL is left for another patch. Signed-off-by:

Rename state to pll_state and use it as the argument to bxt_calc_pll_link(), similar to how it's done in the skl variant. The WARN_ON(!crtc_state->shared_dpll) is not very useful, so remove it as well. Signed-off-by:

Iterate over child devices instead of ports in parse_ddi_ports() to initialize ddi_port_info. We'll eventually need to decide some stuff based on the child device order, which may be different from the port order. As a bonus, this allows better abstractions for e.g. dvo port mapping. There's a subtle change in the DDC pin and AUX channel sanitization as we change the order. Otherwise, this should not change behaviour. Reviewed-by:

Ville Syrjälä authored
The AGPBUSY thing doesn't work on i945gm anymore. This means the gmch is incapable of waking the CPU from C3 when an interrupt is generated. The interrupts just get postponed indefinitely until something wakes up the CPU. This is rather annoying for vblank interrupts as we are unable to maintain a steady framerate unless the machine is sufficiently loaded to stay out of C3. To combat this let's use pm_qos to prevent C3 whenever vblank interrupts are enabled. To maintain reasonable amount of powersaving we will attempt to limit this to C3 only while leaving C1 and C2 enabled. v2: Use READ_ONCE() (Chris) Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=30364Signed-off-by:

Since commit b7137e0c ("drm/i915: Defer enabling rc6 til after we submit the first batch/context"), intel_suspend_gt_powersave() has been a no-op. As we still do not need to do anything explicitly on suspend (we do everything required on idling), remove the defunct function.

Some monitors apparently forget to mark any mode as preferred in the EDID. In this particular case we have a very generic looking ID "PNP Model 0 Serial Number 4" / "LVDS 800x600" so a specific quirk doesn't seem particularly wise. Also the quirk we have (EDID_QUIRK_FIRST_DETAILED_PREFERRED) is actually defunct so we'd have to fix it first. When there is no preferred mode we currently fall back to the VBT. That approach fails us here as the VBT mode is 1024x768 whereas the panel resolution is 800x600. So instead of falling back to the VBT when there is no preferred mode let's just pick the first probed mode. Only if the EDID provided no modes we fall back to the VBT. For this machine the VBIOS would appear to select the 800x600 60Hz EST mode rather than the first detailed mode (which is the new fallback will pick). The two modes differ only by having opposite sync polarities, which does not seem to matter to the panel in question. v2: Make sure the probed_modes list is not empty Cc: Adam Jackson <ajax@redhat.com> Cc: Roberto Viola <cagnulein@gmail.com> Tested-by:

Previously, our view has been always to run the engines independently within a context. (Multiple engines happened before we had contexts and timelines, so they always operated independently and that behaviour persisted into contexts.) However, at the user level the context often represents a single timeline (e.g. GL contexts) and userspace must ensure that the individual engines are serialised to present that ordering to the client (or forgot about this detail entirely and hope no one notices - a fair ploy if the client can only directly control one engine themselves ;) In the next patch, we will want to construct a set of engines that operate as one, that have a single timeline interwoven between them, to present a single virtual engine to the user. (They submit to the virtual engine, then we decide which engine to execute on based.) To that end, we want to be able to create contexts which have a single timeline (fence context) shared between all engines, rather than multiple timelines. v2: Move the specialised timeline ordering to its own function.

It can be useful to have a single ioctl to create a context with all the initial parameters instead of a series of create + setparam + setparam ioctls.
