This is an important part of the DDI initalization as well as for changing the voltage during DisplayPort link training. This new sequence for Cannonlake is more like Broxton style but still with different registers, different table and different steps. v2: Do not write to DW4_GRP to avoid overwrite individual loadgen. Fix PORT_CL_DW5 SUS Clock Config set. v3: As previous platforms use only eDP table if low voltage was requested. v4: fix Werror:maybe uninitialized (Paulo) v5: Rebase on top of dw2_swing_sel changes on previous patches. v6: Using flexible SCALING_MODE_SEL(x).

These tables are used on voltage wswing sequence initialization on Cannonlake. It is a complete new format now in use by the voltage swing team, not following any other standard in use by any other platform. Also the registers are different as well. So let's redefine the translation table for Cannonlake. The table is huge. So we minimized with the fields that are different or might be different anytime soon. The common values will be hardcoded on the voltage swing sequence. v2: Merge the lower and the upper bits to match the spec table and make review easier. This was possible with the good idea for Manasi with a better way to handle it on the bit macro definition presented on previous patch.

This are the registers and bits needed for the voltage swing sequence on Cannonlake. v2: Remove CL_DW5 that was wrongly defined. v3: Use (1 << 1) instead of (1<<1) as Paulo suggested Change DW2 swing sel upper and lower macros to do the bit selection instead of definint a table that doesn't match the spec. It is based on a Manasi version of it. Credits-to: Manasi. v4: Let SCALING_MODE_SEL flexible.

Also new registers can have different mmio offsets per different lane per port. v2: Use _PICK as PORT3 instead of creating a new macro with if per port. v3: Use _PICK directly on MMIO_PORT6. While MMIO_PORT isn't flexible enough let's continue with MMIO_PORT6 as we have MMIO_PORT3.

Although CNL follows PLL initialization more like Skylake than Broxton we have a completely different initialization sequence and registers used. One big difference from SKL is that CDCLK PLL is now exclusive (ADPLL) and for DDIs and MIPI we need to use DFGPLLs 0, 1 or 2. v2: Accept all Ander's suggestions and fixes: - Registers and bits names prefix - Group pll functions - bits masks fixes - remove read and modify on cfgcr1 - fix cfgcr0 setup v3: Set SSC_ENABLE for DP. Fix HDMI_MODE cfgcr0. Avoid touch cfgcr0 on DP. Add missed else on dpll_mgr definition so we use cnl one, not hsw. v3: Centra freq should be always set to default and change bits definitions to (1 << 1) instead of (1<<1). (by Paulo) v4: Rebased.

One of the steps for PLL (un)initialization is to (un)map the correspondent DDI that is actually using that PLL. So, let's do this step following the places already stablished and used so far, although spec put this as part of PLL initialization sequences. v2: Use proper prefix on bits names as suggested by Ander. v3: Add missed "~". Without that the logic was inverted so we were disabling interrupts. Credits-to: Clinton Credits-to: Art v4: Spec is getting updated to do DDI -> PLL mapping and clock on in 2 separated reg writes.

All the low level cdclk bits are present, so let's add the required hooks to reconfigure cdclk on the fly. Cannonlake also needs to adjust the minimal pixel rate as gen9 platforms.

Add support for changing the cdclk frequency on CNL. Again, quite similar to BXT, but there are some annoying differences which means trying to share more code might not be feasible: * PLL ratio now lives in the PLL enable register * pcode came from SKL, not from BXT We support three cdclk frequencies: 168,336,528 Mhz.

Pass crtc_state to the enable callback, and connector_state to all callbacks. This will eliminate the need to guess for the correct pipe in these callbacks. The crtc state is required for pch_enable_backlight to obtain the correct cpu_transcoder. intel_dp_aux_backlight's setup function is called before hw readout, so crtc_state and connector_state->best_encoder are NULL in the enable() and set() callbacks.

Coffee Lake is a Intel
® Processor containing Intel® HD Graphics following Kabylake. It is Gen9 graphics based platform on top of CNP PCH. Let's start by adding the platform definition based on previous platforms but yet as preliminary_hw_support. On following patches we will start adding PCI IDs and the platform specific changes. v2: Also add BS2 ring that is present on GT3. As on KBL, according spec: "GT3 also has additional media blocks with second instance of VEBox and VDBox each", i.e. BSD2 ring in our case. Noticed when reviewing PCI ID patches. v3: CFL_PLATFORM instead for CFL_FEATURES because it contains Platform information and no new features when compared to BDW_FEATURES definition. v4: Rebased on top of Cannonlake patches.

Originally we would enable and disable the breadcrumb interrupt immediately on demand. This was slow enough to have a large impact (>30%) on tasks that hopped between engines. However, by using a shadow to keep the irq alive for an extra interrupt (see commit 67b807a8 ("drm/i915: Delay disabling the user interrupt for breadcrumbs")) and by recently reducing the cost in adding ourselves to the signal tree, we no longer need to spin-request during await_request to avoid delays in throughput tests. Without the earlier patches to stop the wakeup when signaling if the irq was already active, we saw no improvement in execbuf overhead (and corresponding contention in other clients) despite the removal of the spinner in a simple test like glxgears. This means there will be scenarios where now we spend longer enabling the interrupt than we would have spent spinning, but these are not likely to have as noticeable an impact as the high frequency test cases (where there should not be any regression). Ulterior motive: generalising the engine->sync_to to handle different types of semaphores and non-semaphores.

The important condition that we need to check after enabling the interrupt for signaling is whether the request completed in the process (and so we missed that interrupt). A large cost in enabling the signaling (rather than waiters) is in waking up the auxiliary signaling thread, but we only need to do so to catch that missed interrupt. If we know we didn't miss any interrupts (because we didn't arm the interrupt) then we can skip waking the auxiliary thread.

Setting up the irq to signal the request completion takes a finite amount of time, during which it is possible that the request already completed. Check afterwards, just in case, so that we can respond immediately.

Replace the large comment about requiring the powerwell for intel_uncore_arm_unclaimed_mmio_detection() by moving the arming of the mmio error detection into the powerwell held for modesetting. Thereby also accomplishing the goal of only arming the mmio detection after a full modeset.

This patch clean up a bit the platform definition block in a way to avoid duplications and to let clear that GT3 for the current platform only have the extra Media engine (BSD2). v2: Kabylake IS_KABYLAKE as Anusha noticed. v3: Avoid EXTRA_ENGINE_MASK and list rings out on GT3 to make it more clear.

Let's be picky and just use PICK directly. So we can extend this later without creating a new PORT_X por every new number of ports we have to handle.

The workaround added in commit c6782b76 ("drm/i915/gen9: Reset secondary power well equests left on by DMC/KVMR") needs to be applied on Cannonlake as well. So let's assume any platform using this power well setup will also need and let's just go ahead and remove if condition.

CNL power wells are very similar to SKL, with the exception that the misc IO well has been split into separate AUX IO wells. Not sure if DMC is supposed to manage the AUX wells for us or not. Let's assume so for now. v2: DDI A power well wants DDI A domains, not DDI B domains v3: s/BIT/BIT_ULL and add proper Aux IO domains. (Rodrigo) v4: Remove PW_DDI_E. Not supported on Current CNL SKUs. (Rodrigo). v5: Removed DDI_E_IO_DOMAINS and moved PORT_DDI_E_IO to DDI_A_IO for the same reasons as v4 when we found out that current CNL SKUs don't have the full port E split.
