In theory, the BIOS should not even request these from us now that we aren't claiming we support these, but when it does anyway, don't pretend it succeeded. It should be the right thing to do, but might confuse the BIOS. Signed-off-by:

In theory, this should prevent the BIOS from requesting them from us, and this should be the right thing. In practice, this is not always the case, and might surprise the BIOS. Signed-off-by:

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. The locking in register save/restore covers a little more than is strictly necessary, including non-modeset case, for simplicity. v2: Cover register access, save/restore, i915_read_blc_pwm_ctl() and code paths leading there.

In preparation of adding locking to backlight, make max backlight value (the modulation frequency the PWM duty cycle value must not exceed) internal to intel_panel.c. Have intel_panel_set_backlight() accept a caller defined range for level, and scale input to max backlight value internally. Clean up intel_panel_get_max_backlight() and usage internally.

Prevents black screens when using 30bpp framebuffers on my HDMI screens here. The DP input on the same screen though reports a 1.4 EDID with the correct 8bpc limit set. v2: Actually check for the right thing! Reviewed-by:

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.

Ville noticed this while doing another review; we may as well cancel this work just to make sure we don't try anything fancy after disabling the RPS interfaces. Reported-by:

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:

Let's introduce one more of those orthogonal feature macros. This should hopefully make the code more readable and make things easier for new platform enabling. This time, HAS_FPGA_DBG_UNCLAIMED() is true for platforms that have bit 31 of FPGA_DBG able to signal unclaimed writes. Signed-off-by:

Instead of calling into the DRM helper layer to poll all connectors for changes in connected displays probe only those connectors which have received a hotplug event. v2: Resolved conflicts with changes in previous commits.

Sandybridge/Ivybridge, Bay Trail, and Haswell all have slightly different page table entry formats. Rather than polluting one function with generation checks, simply use a function pointer and set up the correct PTE encoding function at startup. v2: Move the gen6_gtt_pte_t typedef to i915_drv.h so that the function pointers and implementations have identical signatures. Also remove inline keyword on gen6_pte_encode. Both suggested by Jani Nikula.

... inside haswell_get_pipe_config. Because there's one TRANS_DDI_FUNC_CTL register per CPU transcoder, not per pipe.

In this commit we enable both CPU and PCH FIFO underrun reporting and start reporting them. We follow a few rules: - after we receive one of these errors, we mask the interrupt, so we won't get an "interrupt storm" and we also won't flood dmesg; - at each mode set we enable the interrupts again, so we'll see each message at most once per mode set; - in the specific places where we need to ignore the errors, we completely mask the interrupts. The downside of this patch is that since we're completely disabling (masking) the interrupts instead of just not printing error messages, we will mask more than just what we want on IVB/HSW CPU interrupts (due to GEN7_ERR_INT) and on CPT/PPT/LPT PCHs (due to SERR_INT). So when we decide to mask PCH FIFO underruns for pipe A on CPT, we'll also be masking PCH FIFO underruns for pipe B, because both are reported by SERR_INT, which has to be either completely enabled or completely disabled (in othe words, there's no way to disable/enable specific bits of GEN7_ERR_INT and SERR_INT). V2: Rename some functions and variables, downgrade messages to DRM_DEBUG_DRIVER and rebase. Signed-off-by: -
