Gen8+ might have mux configurations per slices/subslices. Depending on whether slices/subslices have been fused off, only part of the configuration needs to be applied. This change reworks the mux configurations query mechanism to allow more than one set of registers to be programmed. v2: s/n_mux_regs/n_mux_configs/ (Matthew) Signed-off-by:

Assuming a uniform mask across all slices, this enables userspace to determine the specific sub slices can be enabled. This information is required, for example, to be able to analyse some OA counter reports where the counter configuration depends on the HW sub slice configuration. Signed-off-by:

I removed the zapping of the reservation_object->fence array of shared fences prematurely. We don't yet have the code to zap that array when retiring the object, and so currently it remains possible to continually grow the shared array trapping requests when reusing the batch_pool object across many timelines.

Having resolved whether or not we would deadlock upon a call to mutex_lock(&dev->struct_mutex), we can then spin for the contended struct_mutex if we are not the owner. We cannot afford to simply block and wait for the mutex, as the owner may itself be waiting for the allocator -- i.e. a cyclic deadlock. This should significantly improve the chance of running the shrinker for other processes whilst the GPU is busy. A more balanced approach would be to optimistically spin whilst the mutex owner was on the cpu and there was an opportunity to acquire the mutex for ourselves quickly. However, that requires support from kernel/locking/ and a new mutex_spin_trylock() primitive. Signed-off-by:

In our first pass, we do not want to use reclaim at all as we want to solely reap the i915 buffer caches (its purgeable pages). But we don't mind it initiates IO or pulls via the FS (but it shouldn't anyway as we say no to reclaim!). Just drop the GFP_IO constraint for simplicity. Signed-off-by:

Chris Wilson authored
I tried __GFP_NORETRY in the belief that __GFP_RECLAIM was effective. It struggles with handling reclaim of our dirty buffers and relies on reclaim via kswapd. As a result, a single pass of direct reclaim is unreliable when i915 occupies the majority of available memory, and the only means of effectively waiting on kswapd to amke progress is by not setting the __GFP_NORETRY flag and lopping. That leaves us with the dilemma of invoking the oomkiller instead of propagating the allocation failure back to userspace where it can be handled more gracefully (one hopes). In the future we may have __GFP_MAYFAIL to allow repeats up until we genuinely run out of memory and the oomkiller would have been invoked. Until then, let the oomkiller wreck havoc. v2: Stop playing with side-effects of gfp flags and await __GFP_MAYFAIL v3: Update comments that direct reclaim only appears to be ignoring our dirty buffers!

Commit 24f8e00a ("drm/i915: Prefer to report ENOMEM rather than incur the oom for gfx allocations") made the bold decision to try and avoid the oomkiller by reporting -ENOMEM to userspace if our allocation failed after attempting to free enough buffer objects. In short, it appears we were giving up too easily (even before we start wondering if one pass of reclaim is as strong as we would like). Part of the problem is that if we only shrink just enough pages for our expected allocation, the likelihood of those pages becoming available to us is less than 100% To counter-act that we ask for twice the number of pages to be made available. Furthermore, we allow the shrinker to pull pages from the active list in later passes. v2: Be a little more cautious in paging out gfx buffers, and leave that to a more balanced approach from shrink_slab(). Important when combined with "drm/i915: Start writeback from the shrinker" as anything shrunk is immediately swapped out and so should be more conservative.

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.

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.

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 "~".

Add support for changing the cdclk frequency on CNL.

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.
