HW engineers have listened and given us again a real interrupt with masking and status regs. Yay! For consistency with other platforms call the #define FIFO_UNDERRUN. Eventually we also might need to have some enable/disable functions for bdw display interrupts, but for now open-coding seems to be good enough. Reviewed-by:

Let's cache the IMR value like on other platforms. This is needed to implement the underrun reporting since then we'll have two places that change the same register at runtime. Reviewed-by:

The layout of the CRC registers is the same as on hsw, only the interrupt handling has changed a bit. So trivial to wire up, yay! Reviewed-by:

Gives us hotplug, gmbus, dp aux and south errors (underrun reporting!). Reviewed-by:

Useful for dp aux to work better. Also stop enabling the port A hotplug event - eDP panels are expected to fire that interupt and we're not really ready to deal with them. This is consistent with how we handle port A on ilk-hsw. The more important bit is that we must delay the enabling of hotplug interrupts until all the encoders are fully set up. But we need irq support earlier than that, hence hotplug interrupts can only be enabled in the ->hpd_irq_setup callback. v2: Drop the _HOTPLUG, it isn't (Ville).

- Pipe underrun can't just be enabled, we need some support code like on ilk-hsw to make this happen. So drop it for now. - CRC error is a special mode of the CRC hardware that we don't use, so again drop it. Real CRC support for bdw will be added later. - All the other error bits are about faults, so rename the #define and adjust the output. v2: Use pipe_name as pointed out by Ville. Ville's comment was on a previous patch, but it was easier to squash in here. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

We have a per-pipe bit in the master irq control register, so use it. This allows us to drop the masks for aggregate interrupt bits and be a bit more explicit in the code. It also removes one indentation level. Reviewed-by:

The handling of the error interrupts isn't wired up at all. And it hasn't been ever since ilk happened, so don't bother. Reviewed-by:

Early platforms use the same PCH as HSW, and to avoid triggering the !ULT, and !HSW warnings, simply put it first in the search. Signed-off-by:

Broadwell should also use hsw_crt_get_config(). Just move the function pointer assignment to the if HAS_DDI block we already have there. Signed-off-by:

We've done insufficient testing on them thus far, so keep them disabled until we do test. v2: Use WARN when not enabling preliminary HW support as this should only be disabled for that case. v3: Rip out the now useless (and really noisy) DRM_INFO output.

This is mostly what we have for HSW with the exceptions of: no writes: GEN6_RC1_WAKE_RATE_LIMIT GEN6_RC6pp_WAKE_RATE_LIMIT GEN6_RC1e_THRESHOLD GEN6_RC6p_THRESHOLD GEN6_RC6pp_THRESHOLD GEN6_RP_DOWN_TIMEOUT - use 1s instead of 1.28s Don't try to overclock, or program ring/IA frequency tables since we don't quite have sufficient docs yet. NOTE: These values do not reflect the changes made recently by Chris. Since we have no evidence yet what the proper way to tweak for this platform is, I think it is good to go, and can be optimized by Chris, or whomever, later.

Just like HSW. This means we can scan out a mode with a 300Mhz pixel clock with a depth of 24 bits, but only a 200Mhz one with a 36bits depth. Signed-off-by:

The current formula we use for HSW is not what is in current docs. However, changing to the HSW formula on my HSW does not improve power usage, and decreases performance by about 5% in limited xonotic testing. For gen8, until we know otherwise, or run experiments, let's use the HSW formula - which should be the same used in the Windows driver (and thus help make an apples-applies comparison) on gen8. v2: Use >= 8 instead of > 7 to be consistent with all other gen checks.

Broadwell PSR support is a superset of Haswell. With this simple register base calculation, everything that worked on HSW for eDP PSR should work on BDW. Note that Broadwell provides additional PSR support. This is not addressed at this time. v2: Make the HAS_PSR include BDW v3: Use the correct offset (I had incorrectly used one from my faulty brain) (Art!) v4: It helps if you git add v5: Be explicit about not setting min link entry time for BDW. This should be no functional change over v4 (Jani) Reviewed-by:

Broadwell has different DDI buffer translations for eDP and DP, so add support for the missing eDP and keep Haswell the same. A future patch addresses the suggestion from Art to check for eDP on port D and use the eDP values there, too. v2: Make checkpatch happy. Reviewed-by:

And it inherits some bits from the previous TRANS_CONF (aka PIPE_CONF on previous gens). v2: Rebase on to of the pipe config bpp handling rework. v3: Rebased on top of the pipe_config->dither refactoring. v4: Drop the read-modify-write cycle for PIPEMISC, similarly to how we now also build up PIPECONF completely ourselves - keeping around random stuff set by the BIOS just isn't a good idea.

So you can use the panel fitter while the power well is disabled and you also don't need to set the "pipe" bit. v2: Rebased on top of Jesse's pfit refactor, which moved pfit state into the pipe_config. v3: Rebase on top of the latest Haswell/panel fitter rework, which neatly resolves a FIXME we have in this patch here: v4: Rebase on top of the new power domain framework.

The platforms we currently have all have LPT LP on them. As such, we have no way to identify the new WPT PCH that will ship with Broadwell. NOTE: For all purposes relevant to the driver that this point, LPT and WPT are equivalent.
