The bspec initially provided a single DKL PHY vswing table for both HDMI and DP, but was recently updated to include an independent table for HDMI.

When userspace writes into the GTT itself, it is supposed to call set-domain to let the kernel keep track and so manage the CPU/GPU caches. As we track writes on the individual i915_vma, we should also be sure to mark them as dirty. Signed-off-by:

In order to avoid some nasty mutex inversions, commit 09c5ab38 ("drm/i915: Keep rings pinned while the context is active") allowed the intel_ring unpinning to be run concurrently with the next context pinning it. Thus each step in intel_ring_unpin() needed to be atomic and ordered in a nice onion with intel_ring_pin() so that the lifetimes overlapped and were always safe. Sadly, a few steps in intel_ring_unpin() were overlooked, such as closing the read/write pointers of the ring and discarding the intel_ring.vaddr, as these steps were not serialised with intel_ring_pin() and so could leave the ring in disarray.

When we call intel_dsb_get(), the dsb initialization may fail for various reasons. We already log the error message in that path, making it unnecessary to trigger a warning that refcount == 0 when calling intel_dsb_put(). So here we simplify the logic and do lazy shutdown: leaving the extra refcount alive so when we call intel_dsb_put() we end up calling i915_vma_unpin_and_release(). Signed-off-by:

The current dsb API is not really prepared to handle multithread access. I was debugging an issue that ended up fixed by commit a096883d ("drm/i915/dsb: Remove PIN_MAPPABLE from the DSB object VMA") and was puzzled how these atomic operations were guaranteeing atomicity. if (atomic_add_return(1, &dsb->refcount) != 1) return dsb; Thread A could still be initializing dsb struct (and even fail in the middle) while thread B would take a reference and use it (even derefencing a NULL cmd_buf). I don't think the atomic operations here will help much if this were to support multithreaded scenario in future, so just remove them to avoid confusion. v2: Use refcount++ != 0 instead of ++refcount != 1 (from Ville) Signed-off-by:

When the connector has VCPI allocated and is being moved to another pipe it causes drm_dp_atomic_release_vcpi_slots() and drm_dp_atomic_find_vcpi_slots() to be called in the same atomic check causing the error bellow. This happens because at this point Intel's hw.enable(and all other flags in the same struct) is not set but checking to on the uapi one it have the expected value.

VBT revision 229 adds a new "Generic DTD" block 58 and deprecates the old LFP panel mode data in block 42. Let's start parsing this block to fill in the panel fixed mode on devices with a >=229 VBT. v2: * Update according to the recent updates: - DTD size is now 16 bits instead of 24 - polarity is now just a single bit for hsync and vsync and is properly documented * Minor checkpatch fix v3: * Now that panel options are parsed separately from the previous patch, move generic DTD parsing into a function parallel to parse_lfp_panel_dtd. We'll still fall back to looking at the legacy LVDS timing block if the generic DTD fails. (Jani) * Don't forget to actually set lfp_lvds_vbt_mode! (Jani) * Drop "bdb_" prefix from dtd entry structure. (Jani) * Follow C99 standard for structure's flexible array member. (Jani) v4: * Add "positive" to polarity field names for clarity. (Jani) * Move VBT version check and fallback to legacy DTD parsing logic to a helper to keep top-level VBT parsing uncluttered. (Jani) * Restructure reserved bit packing at end of generic_dtd_entry from "u32 rsvd:24" to "u8 rsvd[3]" to prevent copy/paste mistakes in the future.

On some platforms (e.g. KBL) that do not support GuC submission, but the user enabled the GuC communication (e.g for HuC authentication) calling the GuC EXIT_S_STATE action results in lose of ability to enter RC6. We can remove the GuC suspend/resume entirely as we do not need to save the GuC submission status. Add intel_guc_submission_is_enabled() function to determine if GuC submission is active. v2: Do not suspend/resume the GuC on platforms that do not support Guc Submission. v3: Fix typo, move suspend logic to remove goto. v4: Use intel_guc_submission_is_enabled() to check GuC submission status. v5: No need to look at engine to determine if submission is enabled. Squash fix + intel_guc_submission_is_enabled() patch into one. v6: Move resume check into intel_guc_resume() for symmetry. Fix commit Fixes tag.

Currently we're blindly poking at the frame start delay bits in PIPECONF when trying to sanitize the hardware state. Those bits decided to move elsewhere on HSW, so on many platforms we're not doing anything at all here. Also we're forgetting about the PCH transcoder entirely. Add all the bit definitions for the various homes these bits have had throughout the years, and reset them all to zero. However I'm not entirely sure this is a safe thing to do. If not I guess we'd want full readout+statecheck for this stuff. For now let's stick to the current logic and hope for the best. Signed-off-by:

Our callers fall into two categories, those passing timeout=0 who just want to flush request retirements and those passing a timeout that need to wait for submission completion (e.g. intel_gt_wait_for_idle()). Currently, we only wait for a snapshot of timelines at the start of the wait (but there was an expectation that new requests would cause timelines to appear at the end). However, our callers, such as intel_gt_wait_for_idle() before suspend, do require us to wait for the power management requests emitted by retirement as well. If we don't, then it takes an extra second or two for the background worker to flush the queue and mark the GT as idle.

With the new interrupt re-partitioning in Gen11, GuC controls by itself the interrupts it receives, so steering bits and registers have been defeatured. Being this the case, when the GuC is in control of submissions we won't know what to do with the ctx switch interrupt in the driver, so disable it. v2 (Daniele): replace the gen9 paths instead of keeping gen9 and gen11 functions since we won't support guc submission on any pre-gen11 platform.

fbdev uses the physical address of our framebuffer for its fb_mmap() routine. While we need to adapt this address for the new io BAR, we have to fix v5.4 first! The simplest fix is to restore the smem back to v5.3 and we will then probably have to implement our fbops->fb_mmap() callback to handle local memory. Reported-by:
