Make the min_pixclk thing less confusing by changing it to track the minimum acceptable cdclk frequency instead. This means moving the application of the guardbands to a slightly higher level from the low level platform specific calc_cdclk() functions. The immediate benefit is elimination of the confusing 2x factors on GLK/CNL+ in the audio workarounds (which stems from the fact that the pipes produce two pixels per clock). v2: Keep cdclk higher on CNL to workaround missing DDI clock voltage handling v3: Squash with the CNL cdclk limits patch (DK) v4: s/intel_min_cdclk/intel_pixel_rate_to_cdclk/ (DK) Cc: Paulo Zanoni <paulo.r.zanoni@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Reviewed-by:

On clock recovery this function is called to find out the max voltage swing level that we could go. However gen 9 functions use the old buffer translation tables to figure that out. That table is not valid for CNL causing an invalid number of entries and an invalid selection on the max voltage swing level. v2: Let's use same approach that previous platforms. v3: Actually use n_entries and avoid duplicated -1. v4: Avoid cnl_max_level and use current style.

Let's get a proper HDMI DDI entry level for vswing programming sequences on CNL. Spec doesn't specify any default for HDMI tables, so let's pick the last entry as the default for now. Signed-off-by:

No functional changes. But those functions will be needed to get max level for HDMI and DP, so let's move those up closer to other similar functions existent for previous platforms. Signed-off-by:

Let's start converging CNL buf translations to same style used on previous platforms. So first thing is to use the standard signature so we don't need to propagate the voltage check into other parts of the code, but only on the parts that it is really useful. Signed-off-by:

Sequences for DisplayPort asks us to " Configure voltage swing and related IO settings. Refer to DDI Buffer section." before "Configure and enable DDI_BUF_CTL" On BXT and CNL this means to execute the ddi vswing sequences. At this point these sequences calls are getting duplicated for DP because they are all called from DP link trainning sequences. However this patch is not yet removing it before a futher discussion since spec also allows that during link training without disabling anything: " Notes Changing voltage swing during link training: Change the swing setting following the DDI Buffer section. The port does not need to be disabled. " Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by:

Vswing sequences on BXT and CNL are equivalent to the ddi buffer registers setting on other platforms. For some reason it got aligned with skl_ddi_set_iboost what is semantically incorrect. This forced us to keep skipping ddi buffer translation tables on the platforms that has the vswing sequences. v2: Don't mess with DP signal levels on this patch.

Let's decouple bxt, glk and cnl dp signal levels from other DDIs to avoid confusion. No functional change. Only a reorg to avoid messing with currently working DP signal levels when moving voltage swing sequences around to match spec. v2: ddi_signal_levels is also called from other ddi platforms, so don't remove IS_GEN9_BC check from skl_ddi_set_iboos.

Driver’s CPU access to GTT is via the GTTMMADR BAR. The current HW implementation of that BAR is to only support <= DW (and maybe QW) writes—not 16/32/64B writes that could occur with WC and/or SSE/AVX moves. GTTMMADR must be marked uncacheable (UC). Accesses to GTTMMADR(GTT), must be 64 bits or less (ie. 1 GTT entry). v2: Get clarification on the reasons and spec is getting updated to reflect it now.

Since we hold the device wakeref when writing through the GTT (otherwise the writes would fail), we presumed that before the device sleeps those writes would naturally be flushed and that we wouldn't need our mmio read trick. However, that presumption seems false and a sleepy bxt seems to require us to always manually flush the GTT writes prior to direct access.

Chris Wilson authored
When we do a locked idle we know that afterwards all requests have been completed and the engines have been cleared of tasks. For whatever reason, this doesn't always happen and we may go into a suspend with ELSP still full, and this causes an issue upon resume as we get very, very confused. If the engines refuse to idle, mark the device as wedged. In the process we get rid of the maybe unused open-coded version of wait_for_engines reported by Nick Desaulniers and Matthias Kaehlcke. v2: Suppress the -EIO before suspend, but keep it for seqno wrap.

Sometimes we know we are the only user of the bo, but since we take a protective pin_pages early on, an attempt to change the vmap on the object is denied because it is busy. i915_gem_object_pin_map() cannot tell from our single pin_count if the operation is safe. Instead we must pass that information down from the caller in the manner of I915_MAP_OVERRIDE. This issue has existed from the introduction of the mapping, but was never noticed as the only place where this conflict might happen is for cached kernel buffers (such as allocated by i915_gem_batch_pool_get()). Until recently there was only a single user (the cmdparser) so no conflicts ever occurred. However, we now use it to allocate batches for different operations (using MAP_WC on !llc for writes) in addition to the existing shadow batch (using MAP_WB for reads). We could either keep both mappings cached, or use a different write mechanism if we detect a MAP_WB already exists (i.e. clflush afterwards), but as we haven't seen this issue in the wild (it requires hitting the GPU reloc path in addition to the cmdparser) for simplicity just allow the mappings to be recreated. v2: Include the i915_MAP_OVERRIDE bit in the enum so the compiler knows about all the valid values.
