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:Jesse Barnes <jbarnes@virtuousgeek.org> Reviewed-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:

Now that we have function pointers, it's cleaner to just create a new per-platform PTE encoding function. This should be identical in behavior to the previous code. v2: Drop accidental inline keyword on hsw_pte_encode. Signed-off-by:

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: -

In Valleyview voltage swing, pre-emphasis and lane control registers can be programmed only through the h/w side band fabric. Update vlv_update_pll, i9xx_crtc_enable, and intel_enable_pll with the appropriate programming.

We can only enable the pfit if the pipe is disabled. Ensure that this is obeyed with a neat assert.

For a bunch of reason we need to more accurately track this: - hw pipe state readout for Haswell needs the cpu transcoder. - We need to know the right cpu transcoder in a bunch of places in ->disable and other modeset callbacks. In the future we need to add hw state readout&check support, too. But to avoid ugly merge conflicts do the rote sed job now without any functional changes. v2: Preserve the cpu_transcoder value when overwriting crtc->config. Reported by Paulo.
