Given the history, there's some chance we'll keep the same WM code for a bit (previously, we were able to reuse the same WM code from ILK to BDW, so that sounds like a fair assumption). Signed-off-by:

Write and reads following the block changed use engine specific use counters and unless that is matched here force wake use counting goes bad. Same force wake is attempted to be taken twice which leads to at least time outs. NOTE: Depending on feedback from hardware designers it may not be necessary to grab force wakes on Gen9 here. But for Gen8 it is needed due to a race between RC6 and ELSP writes. v2: Added blitter force wake engine and made more future proof. Added commit note.

Ville found out that the DATA1 register exists since SNB with some scarce apparitions in the specs throughout the times. In his own words: Also according to Bspec the mailbox data1 register already existed since snb. The hsw cdclk change sequence also mentions that it should be set to 0, but eg. the bdw IPS sequence doesn't mention it. I guess in theory some pcode command might cause it to be clobbered, so I'm thinking we should just explicitly set it to 0 for all platforms in the pcode read/write functions Reviewed-by:

On skylake, DPLL 1, 2 and 3 can be used for DP and HDMI. The shared dpll framework allows us to share those DPLLs among DDIs when possible. The most tricky part is to provide a DPLL state that can be easily compared. DPLL_CRTL1 is shared by all the DPLLs, 6 bits each. The per-dpll crtl1 field of the hw state is then normalized to be the same value if 2 DPLLs do indeed have identical values for those 6 bits. v2: Port the code to the shared DPLL infrastructure (Damien) v3: Rebase on top of Ander's clock computation staging work for atomic (Damien) Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> (v2) Signed-off-by: Satheeshakrishna M <satheeshakrishna.m@intel.com> (v1) Signed-off-by:

This is not used within the driver, and merely saving/restoring these registers isn't going to do any good anyway. In fact, it's possible it's actively harmful.

AFAICT i9xx_pfit_disable() on the GMCH display crtc disable path in i9xx_crtc_disable() will always disable the panel fitter by writing 0 to PFIT_CONTROL. The register save will always save/restore 0. Also we completely recompue both in intel_gmch_panel_fitting so there's no way we depend upon leftover bits. Move the PFIT_CONTROL and PFIT_PGM_RATIOS save/restore to UMS code. While at it, save/restore them both under the same conditions. Signed-off-by:

The predicate source registers are needed to implement conditional rendering without stalling. The two source registers are used to load the previous values of the PS_DEPTH_COUNT register saved from PIPE_CONTROL commands. These can then be compared and used to set the predicate enable bit via the MI_PREDICATE command. The command parser version number is increased to 2 to make it easier to detect the new functionality in user space. Signed-off-by:

This only affects the fastboot path as-is. In that case, we simply need to make sure that we update the pipe size at the first mode set. Rather than putting it off until we decide to flip (if indeed we do end up flipping), update the pipe size as appropriate a bit earlier in the set_config call. This sets us up for better pipe tracking in later patches. Signed-off-by:

Now that the backlight device no longer gets registered too early we should be able to drop most of the INVALID_PIPE checks from the backlight code. The only exceptio is the opregion stuff where we may (in theory at least) get a request from the BIOS already during driver init as soon as the backlight setup has been done. In which case we can still get the INVALID_PIPE from intel_get_pipe_from_connector(). So leave that check in place, and add a comment explaining why. For the rest, if we still manage to get here with INVALID_PIPE on VLV/CHV we will now get a WARN from the lower level functions and can then actually investigate further. v2: Leave the check in the BIOS related code (Jani) Cc: Jani Nikula <jani.nikula@intel.com> Signed-off-by:

Currently we register the backlight device as soon as we register the connector. That means we can get backlight requests from userspace already before reading out the current modeset hardware state. That means we don't yet know the current crtc->encoder->connector mapping, which causes problems for VLV/CHV which need to know the current pipe in order to figure out which BLC registers to poke. Currently we just ignore such requests fairly deep in the backlight code which means the backlight device brightness property will get out of sync with our backlight.level and the actual hardware state. Fix the problem by delaying the backlight device registration until the entire modeset init has been performed. And we also move the backlight unregisteration to happen as the first thing during the modeset cleanup so that we also won't be bothered with userspace backlight requested during teardown. This is a real world problem on machines using systemd, because systemd, for some reason, wants to restore the backlight to the level it used last time. And that happens as soon as it sees the backlight device appearing in the system. Sometimes the userspace access makes it through before the modeset init, sometimes not. v2: Do not lie to the user in the debug prints (Jani) Include connector name in the prints (Jani) Fix a typo in the commit message (Jani) Reviewed-by: -

On VLV/CHV both pipes A and B have their own backlight control registers. In order to correctly read out the current hardware state at init we need to know which pipe is driving the eDP port. Pass that information down from the eDP init code into the backlight code. To determine the correct pipe we first look at which pipe is currently configured in the port control register, if that look invalid we look at which pipe's PPS is currently controlling the port, and if that too looks invalid we just assume pipe A.

If the connector would have an encoder but the encoder didn't have a crtc we might dereference a NULL crtc here. I suppose that should never happen due to intel_sanitize_encoder(), but let's be a bit paranoid print a warning if we ever hit this and return INVALID_PIPE to the caller. Signed-off-by:

On VLV/CHV when the display is off, we can't read out the current backlight level from the hardware since we have no pipe to do so. Currently we end up reading a bigus register due to passing INVALID_PIPE to VLV_BLC_PWM_CTL(). Skip the entire .get_backlight() call if the backlight isn't enabled according to backlight.enabled. This problem can be reproduced simply by reading the backlight device actual_brightness file while the display is off. Cc: Jani Nikula <jani.nikula@intel.com> Suggested-by:
