Instead of repeatedly bombarding the user with a request to reboot and increase the stolen size with every fb refresh, just inform them the first time only. v2: Rearrange code so the hint to increase the amount of memory stolen by the BIOS is only emitted if we fail to find sufficient stolen memory for FBC.

This gets the panel fitter working on eDP on VLV, and should also apply to eDP panels on G4x chipsets (if we ever detect and mark an all-in-one panel as eDP anyway). A few cleanups are still possible on top of this, for example the LVDS border control could be placed in the LVDS encoder structure and updated based on the result of the panel fitter calculation. Multi-pipe fitting isn't handled correctly either if we ever get a config that wants to try the panel fitter on more than one output at a time. v2: use pipe_config for storing pfit values (Daniel) add i9xx_pfit_enable function for use by 9xx and VLV (Daniel) v3: fixup conflicts and lvds_dither check Reviewed-by: -

g4x dplls and ilk+ pch plls have a separate field for the reduced p1 setting, so this restriction does not apply. Only older platforms have the restriction that the p1 divisors must match. This unnecessary restriction has been introduced in commit cec2f356 Author: Sean Paul <seanpaul@chromium.org> Date: Tue Jan 10 15:09:36 2012 -0800 drm/i915: Only look for matching clocks for LVDS downcloc Note that with lvds the p2 divisors _always_ match for LVDS, and we don't support auto-downclocking anywhere else. On eDP downclocking works with separate data m/n settings, using the same link clock. Cc: Sean Paul <seanpaul@chromium.org> Reviewed-by:

Up to now we've relied on the bios to get this right for us. Let's try out whether our code has improved a bit, since we should dither always when the output bpp doesn't match the plane bpp. - gen5+ should be fine, since we only use the bios hint as an upgrade. - gen4 changes, since here dithering is still controlled in the lvds register. - gen2/3 has implicit dithering depeding upon whether you use 2 or 3 lvds pairs (which makes sense, since it only supports 8bpc pipe outpu configurations). - hsw doesn't support lvds. v2: Remove redudant dither setting. v3: Completly drop reliance on dev_priv->lvds_dither. v4: Enable dithering on gen2/3 only when we have a 18bpp panel, since up-dithering to a 24bpp panel is not supported by the hw. Spotted by Ville. v5: Also only enable lvds port dithering on gen4 for 18bpp modes. In practice this only excludes dithering a 10bpc plane down for a 24bpp lvds panel. Not something we truly care about. Again noticed by Ville. v6: Actually git add. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

With the exception of hsw, which has dedicated DP clocks which run at the fixed frequency already, and vlv, which doesn't have optmized pre-defined dp clock parameters (yet). v2: Ville asked me to elaborate a bit more on the longer-term goals wrt dpll settings computation: So ultimately my idea is that in the compute config stage first the crtc code puts the default platform pll limits into the pipe_config. Then encoders can either overwrite that limit structure with their own special stuff (mostly for lvds madness). Or they can pick some or all of the parameters (e.g. just the p2 switchover on hdmi, or all the clock parameters for dp/sdvo tv). Once that's done then the generic crtc code can fill out any missing bits (using the find_best_pll code) and then try to assign which pll to use (if it's a platform with shared plls). In the end the modeset could should simply write the computed stuff into registers and never be able to fail. Of course there's still a lot of data to be moved into pipe_config to make this all happen, hence some of the temporary ugliness.

Backlight data and registers are fiddled through LVDS/eDP modeset enable/disable hooks, backlight sysfs files, asle interrupts, and register save/restore. Protect the backlight related registers and driver private fields using a spinlock.

Our rps code relies on the interrupts being off to prevent re-arming of the work items at inopportune moments. Also drop the redundant cancel_work for the main rps work, disable_gt_powersave already takes care of that. Finally add a WARN_ON to ensure we obey that piece of ordering constraint. Long term I want to lock down the setup/teardown code in a similar way to how we painstakingly check modeset sequence constraints already. v2: Disable polling after hpd handling is shut down - since Egbert's hpd irq storm handling the hotplug work can re-arm the polling handler.

On VLV, the Punit doesn't automatically drop the GPU to it's minimum voltage level when entering RC6, so we arm a timer to do it for us from the RPS interrupt handler. It'll generally only fire when we go idle (or if for some reason there's a long delay between RPS interrupts), but won't be re-armed again until the next RPS event, so shouldn't affect power consumption after we go idle and it triggers. v2: use delayed work instead of timer + work queue combo (Ville) v3: fix up delayed work cancel (must be outside lock) (Daniel) fix up delayed work handling func for delayed work (Jesse) v4: cancel delayed work before RPS shutdown (Jani) pass delay not absolute time to mod_delayed_work (Jani) Signed-off-by:
