Instead of doing a hack during primary plane commit the state is updated during atomic evasion. It handles differences in pipe size and the panel fitter. This is continuing on top of Daniel's work to make faster modesets atomic, and not yet enabled by default. Signed-off-by:

The initial state is read out correctly and the state is atomic, so it's safe to preserve the fb without any hacks if it's suitable. Signed-off-by:

This function was still using the legacy state, convert it to atomic. While we're at it, fix the FIXME too and disable the primary plane. v2 (Daniel): - Add FIXME explaining that update_primary_planes should soon get removed anyway. - Don't call ->disable_plane since we can't disable the primary plane with a CS flip (noticed by Ville).

Normally we determine the backlight PWM modulation frequency (which we also use as backlight max value) from the backlight registers at module load time, expecting the registers have been initialized by the BIOS. If this is not the case, we fail. The VBT contains the backlight modulation frequency in Hz. Add platform specific functions to convert the frequency in Hz to backlight PWM modulation frequency, and use them to initialize the backlight when the registers are not initialized by the BIOS. v2: Fix SPT and VLV. Thanks to Clint for the VLV code. Cc: Clint Taylor <clinton.a.taylor@intel.com> Signed-off-by:

Currently the difference between backlight control on HSW vs. BDW/SKL is that on HSW we modify the duty cycle on the CPU register, and have the hardware pass the changes on to the PCH registers. We still drive the PCH PWM on both. While HSW and BDW use the same LPT PCH, BDW does not pass these messages on to the PCH. Therefore on BDW we need to enable the PCH override bit, and program the PCH directly. (On SPT PCH, this mode is the default.) We could as well do this on HSW too, and in fact I've been told this is what a certain other operating system does. So use PCH backlight override on HSW too. This simplifies some follow-up code, but it does have the danger of breaking backlight on HSW machines. It should work, but mysterious are the ways of backlight. While at it, name the related backlight hooks according to the PCH rather than the CPU for clarity. Cc: Clint Taylor <clinton.a.taylor@intel.com> Signed-off-by:

These registers exist only before GEN5, so currently we may access undefined registers on VLV/CHV and BXT. Apply the workaround only pre GEN5. Since the workaround is relevant only when LVDS is present, for clarity apply it only if this is the case.

TPS3 is mandatory for downstream devices that support HBR2, and Intel platforms that support HBR2 also support TPS3. Whenever TPS3 is supported by both the source and sink, it should be used. In other words, whenever the source and sink are capable of 5.4 Gbps link, we should anyway go for TPS3, regardless of the link rate being selected. Log an error if the sink has advertized HBR2 capability without TPS3 capability. Reviewed-by:

On each call to gen8_alloc_va_range_3lvl we're allocating temporary bitmaps needed for error handling. Unfortunately, when we increase address space size (48b ppgtt) we do additional (512 - 4) calls to kcalloc, increasing latency between exec and actual start of execution on the GPU. Let's just do a single kcalloc, we can also drop the size from free_gen8_temp_bitmaps since it's no longer used. v2: Use GFP_TEMPORARY to make the allocations reclaimable. v3: Drop the 2D array, just allocate a single block. v4: Rebase to handle gen8_preallocate_top_level_pdps. v5: Align misaligned bracket.

Rewrite the BXT hpd setup to match the way we do it on other platforms: - Throw out BXT_HOTPLUG_CTL since it's the same as PCH_PORT_HOTPLUG - Enable the HPD bits in the DE port IER in gen8_de_irq_postinstall() - Update DE port IMR using bdw_update_port_irq() Also throw out port D from bxt_port_hotplug_long_detect() since BXT only goes up to C.

A lot of the hpd irq handling is duplicated code, so refactor it a bit by observing that in several places the only difference is the hpd[] array. So pull the code to a few functions and pass in the hpd[] array from the caller. Another option would be to determine the correct array to use within the functions themselves, but somehow passing it in felt nicer. Further code reduction could be achieved by passing in the hotplug register offset, and the long pulse detection function pointer. But that didn't feel as good for some reason, so I left it at the middle ground. Signed-off-by:
