Currently we just clamp that value to the highest supported one, however that means, we are not able to fit this into our available bandwidth range, so we might see glitches or FIFO underruns. While choosing less compressed bpp than min bpp required to handle the mode is harmless and might even save some bandwidth, choosing higher compressed bpp than min bpp required to handle the required mode config, can cause issues. So in that case lets just conclude that even with DSC, we are not able to comply with bandwidth requirements and fail. v2: - s/clamp_t/min_t/ (Luca Coelho) Signed-off-by:

Instead of modifying the device info on the fly, use static const mock device info. It's not okay to modify device info at runtime; we've added separate runtime info for info that needs to be modified at runtime. We've added safeguards to device info to prevent it from being modified, but commit 5e352e32 ("drm/i915: preparation for using PAT index") just cast the const away and modified it anyway. This prevents device info from being moved to rodata. Fixes: 5e352e32 ("drm/i915: preparation for using PAT index") Suggested-by:

DC states are disabled / re-enabled around each modeset, which may lead to a needless off->on->off toggling of the DC_off power well. This has some overhead as toggling DC states involves running a DMC firmware handler and also running a periodic firmware handler while DC states are enabled. The limit of when DC states have a benefit is at 30 FPS (using DC3co) and below 30 FPS (using DC5/6), where the firmware can actually disable clocks / power off power wells. Accordingly delay powering off the DC_off powerwell (which re-enables DC states) by 17 ms at the end of a modeset to avoid the above overhead at or above 60 FPS. Reviewed-by:

Add support for specifying a delay different than the current 100 ms default for powering off a display power domain. This is needed by the next patch which delays re-enabling DC states during modesets to avoid the off->on->off toggling overhead of the DC_off power well, but does this using a < 100 ms delay for a better utilization of DC power saving states.

Make HSW/BDW use port_mask for output probing as well. To achieve that the strap checks are moved into intel_ddi_init() itself. Or should we move them to the runtime port_mask init instead?

Instead of listing every platform's possible DDI outputs in intel_setup_outputs() just loop over the new port_mask to achieve the same thing. HSW/BDW were left as is since they still look at the straps as well. DSI is still a mess. For now just check for the relevant platforms explicitly. Reviewed-by:

The SDVO code already warns when the port in question doesn't actually support SDVO. Let's make that also bail the encoder registration like the generic assert_port_valid() we added. And add a similar thing for g4x HDMI, mainly because on g4x itsefl port D only supports DP but not SDVO/HDMI. For the other platforms the generic port_mask check should actually be sufficient, but since we're here might as well list the ports. Reviewed-by:

Sprinkle some asserts to catch any mishaps in the port_mask vs. output init. For DDI/DP/HDMI/SDVO I decided that we want to bail out for an invalid port since those are the encoder types where we might want consider driving the whole thing from the VBT child device list, and bogus VBTs could be a real issue (if for no other reason than the i915.vbt_firmware). For DVO and HSW/BDW CRT port I just threw the assert in there for good measure. Reviewed-by:

Declare the available DVO/SDVO/HDMI/DP/DDI ports in the device info. The other outputs (LVDS/TV/DSI/VGA) are left out since for most of them we don't consider them as "ports". DSI we should probably perhaps include somehow in the device info. Just not sure how. Or we just introduce a HAS_DSI() and call it a day? TODO: figure out what to do about the subplatform stuff. Would it be better to declare those directly with a different device info or not? Also not sure the icl port-f stuff matters even. Bspec claims there are icl SKUs with far less ports than that and we don't seem to check for those either? v2: Fix TC5 vs. TC6 mixup on TGL (Jani) Drop DDI C for now on TGL, and add a FIXME (Jani) Reviewed-by:Uma Shankar <uma.shankar@intel.com> Signed-off-by:

hsw/bdw lack the pipe register vs. display register distinction in their PSR masking capabilities. So to keep our CURSURFLIVE tricks working we need to just unmask all display register writes on these platforms. The downside being that any display regitster (eg. even SWF regs) will cause a PSR exit. Note that WaMaskMMIOWriteForPSR asks us to mask this on bdw, but that won't work since we need those CURSURFLIVE tricks. Observations on actual hardware show that this causes one extra PSR exit ~every 10 seconds, which is pretty much irrelevant. I suspect this is due to the pcode poking at IPS_CTL. Disabling IPS does not stop it however, so either I'm wrong or pcode pokes at the register regardless of whether it's actually trying to enable/disable IPS. Also when the machine is busy (eg. just running 'find /') these extra PSR exits cease, which again points at pcode or some other PM entity as being the culprit. Signed-off-by:

Bspec asks us to unmask "vblank to registers" in the DPRS unit. Note that I was unable to observe any change in hardware behviour due to this bit on HSW. But let's do this anyway in case it matters in some cases, and the corresponding bit on BDW is abolutely critical as without it the hardware won't generate any vblanks whatsoever after PSR exit.

Implement WaPsrDPAMaskVBlankInSRD:hsw, which makes the hardware generate the extra vblank between link training and first frame being transmitted. This is the same thing that's controlled by TRANS_CHICKEN[21] on skl+ (but due to the funky double buffering it's effectively always at the rest value after DC5 exit). So for consistent behaviour we want every platform to generate said vblank. BDW is already setting this up correctly. Signed-off-by:
