This patch adds the DP MST audio support on i915 platform and it will enable dyn_pcm_assign feature. DP MST supports several device entry on the same port and each device entry can map to one pcm stream. For example, on i915, there are 3 pins, and each pin has 3 device entries. This means there should be 3x3 pcms. However, there is only 3 pipe lines in i915. This means 3 pcms are actived at most at the same moment. We will create 5 pcms (pin number + dev entry num - 1) in this case. For the details, please refer commit a76056f2 ("ALSA: hda - hdmi dynamically bind PCM to pin when monitor hotplug") Each device entry is a virtual pin. It is described by pin_nid and dev_id in struct hdmi_spec_per_pin. Reviewed-by:

The vma->exec_list is still the only means we have for both reserving an object in execbuf, and for constructing the eviction list. So during the construction of the eviction list, we must treat anything already on the exec_list as being pinned. Yes, this sharing of two semantically different lists will be fixed! But in the meantime, we have the issue that this is tripping up CI since we started using i915_gem_gtt_reserve_node() + i915_gem_evict_for_node() from the regular execbuf reservation path in commit 606fec95 ("drm/i915: Prefer random replacement before eviction search"): [ 108.424063] kernel BUG at drivers/gpu/drm/i915/i915_vma.h:254!

It is an error to start a new request on the same timeline (ringbuffer) as the current one before the current is submitted. If there are two requests emitting to the ringbuffer at the same time, the operation is undefined. We can catch this by checking for the timeline having a later seqno than ours when we come to submit our request. Currently we have this check at the end of __i915_add_request, but having an early check as well isolates a failure in the caller versus a failure in sealing the request (i.e. from inside __i915_add_request itself). For example, CI is currently tripping over this late assertion on ctg/ilk: [ 100.329399] [IGT] gem_cs_tlb: starting subtest basic-default [ 100.336333] ------------[ cut here ]------------ [ 100.336341] kernel BUG at drivers/gpu/drm/i915/i915_gem_request.c:908!

Performing an eviction search can be very, very slow especially for a range restricted replacement. For example, a workload like gem_concurrent_blit will populate the entire GTT and then cause aperture thrashing. Since the GTT is a mix of active and inactive tiny objects, we have to search through almost 400k objects before finding anything inside the mappable region, and as this search is required before every operation performance falls off a cliff. Instead of performing the full search, we do a trial replacement of the node at a random location fitting the specified restrictions. We lose the strict LRU property of the GTT in exchange for avoiding the slow search (several orders of runtime improvement for gem_concurrent_blit 4KiB-global-gtt, e.g. from 5000s to 20s). The loss of LRU replacement is (later) mitigated firstly by only doing replacement if we find no freespace and secondly by execbuf doing a PIN_NONBLOCK search first before it starts thrashing (i.e. the random replacement will only occur from the already inactive set of objects). v2: Ascii-art, and check preconditionst v3: Rephrase final sentence in comment to explain why we don't bother with if (i915_is_ggtt(vm)) for preferring random replacement.

Start converting over from the byte count to its semantic macro, either we want to allocate the size of a physical page in main memory or we want the size of a virtual page in the GTT. 4096 could mean either, but PAGE_SIZE and I915_GTT_PAGE_SIZE are explicit and should help improve code comprehension and future changes. In the future, we may want to use variable GTT page sizes and so have the challenge of knowing which hardcoded values were used to represent a physical page vs the virtual page. v2: Look for a few more 4096s to convert, discover IS_ALIGNED(). v3: 4096ul paranoia, make fence alignment a distinct value of 4096, keep bdw stolen w/a as 4096 until we know better. v4: Add asserts that i915_vma_insert() start/end are aligned to GTT page sizes.

Let userspace know if its request was resubmitted due to it being executed at the time of a global reset. In this case, the reset was for a guilty request on another engine, and this request was an innocent victim that will be re-executed upon restarting. However, since it was running at the time of the reset, we can not guarantee that it suffered no ill-effects from the reset (e.g. some context state may be lost, or some self-modifying fragment shaders will be restarted from the final state not their initial state), to let userspace know that it has been corrupted set a special value on the fence->error, -EAGAIN. If the request does hang on resubmission, the error will be overwritten with -EIO. Signed-off-by:

The struct dma_fence carries a status field exposed to userspace by sync_file. This is inspected after the fence is signaled and can convey whether or not the request completed successfully, or in our case if we detected a hang during the request (signaled via -EIO in SYNC_IOC_FILE_INFO). v2: Mark all cancelled requests as failed.

Always reset the requests of the guilty context, including the hung request that we tell the hardware to skip. This should help if the reprogram fails entirely, but more importantly makes the guilty path more uniform (and simplifies the subsequent patch to tweak the cancelled requests). Signed-off-by:

The core provides now an ABI to userspace for generation of frame CRCs, so implement the ->set_crc_source() callback and reuse as much code as possible with the previous ABI implementation. When handling the pageflip interrupt, we skip 1 or 2 frames depending on the HW because they contain wrong values. For the legacy ABI for generating frame CRCs, this was done in userspace but now that we have a generic ABI it's better if it's not exposed by the kernel. v2: - Leave the legacy implementation in place as the ABI implementation in the core is incompatible with it. v3: - Use the "cooked" vblank counter so we have a whole 32 bits. - Make sure we don't mess with the state of the legacy CRC capture ABI implementation. v4: - Keep use of get_vblank_counter as in the legacy code, will be changed in a followup commit. v5: - Skip first frame or two as it's known that they contain wrong data. - A few fixes suggested by Emil Velikov. v6: - Rework programming of the HW registers to preserve previous behavior. v7: - Address whitespace issue. - Added a comment on why in the implementation of the new ABI we skip the 1st or 2nd frames. v9: - Add stub for intel_crtc_set_crc_source. v12: - Rebased. - Remove stub for intel_crtc_set_crc_source and instead set the callback to NULL (Jani Nikula). v15: - Rebased.

Rename i915_gem_get_ggtt_size() and i915_gem_get_ggtt_alignment() to i915_gem_fence_size() and i915_gem_fence_alignment() respectively to better match usage. Similarly move the pair of functions into i915_gem_tiling.c next to the fence restrictions. Suggested-by:

Restricting the fence to the end of the previous tile-row breaks access to the final portion of the object. On gen2/3 we employed lazy fencing to pad out the fence with scratch page to provide access to the tail, and now we also pad out the object on gen4+ we can apply the same fix.

The fence size/alignment is a combination of the vma size plus object tiling parameters. Those parameters are rarely changed, making the fence size/alignemnt roughly constant for the lifetime of the VMA. We can simplify subsequent calculations by precalculating the size/alignment required for GGTT vma taking fencing into account (with an update if we do change the tiling or stride). Signed-off-by:

All of these conditions are prechecked by i915_tiling_ok() before we allow setting the tiling/stride on the object and so we should never fail asserting those conditions before writing the register. Signed-off-by:

Ensure the view occupies the full tile row so that reads/writes into the VMA do not escape (via fenced detiling) into neighbouring objects - we will pad the object with scratch pages to satisfy the fence. This applies the lazy-tiling we employed on gen2/3 to gen4+. Signed-off-by:

Computing the tile row size of a tiled object (for use with fence registers) is repeated, so extract it to a common helper. Signed-off-by:

The dma_fence.error field (formerly known as dma_fence.status) is an optional field that may be set by drivers before calling dma_fence_signal(). The field can be used to indicate that the fence was completed in err rather than with success, and is visible to other consumers of the fence and to userspace via sync_file. This patch renames the field from status to error so that its meaning is hopefully more clear (and distinct from dma_fence_get_status() which is a composite between the error state and signal state) and adds a helper that validates the preconditions of when it is suitable to adjust the error field.

The fence->status is an optional field that is only valid once the fence has been signaled. (Driver may fill the fence->status with an error code prior to calling dma_fence_signal().) Given the restriction upon its validity, wrap querying of the fence->status into a helper dma_fence_get_status(). Signed-off-by:
