+Realtek PC Beep Hidden Register
+===============================
+
+This file documents the "PC Beep Hidden Register", which is present in certain
+Realtek HDA codecs and controls a muxer and pair of passthrough mixers that can
+route audio between pins but aren't themselves exposed as HDA widgets. As far
+as I can tell, these hidden routes are designed to allow flexible PC Beep output
+for codecs that don't have mixer widgets in their output paths. Why it's easier
+to hide a mixer behind an undocumented vendor register than to just expose it
+as a widget, I have no idea.
+
+Register Description
+====================
+
+The register is accessed via processing coefficient 0x36 on NID 20h. Bits not
+identified below have no discernible effect on my machine, a Dell XPS 13 9350::
+
+ MSB LSB

+ When zero, expose the PC Beep line (from the internal beep generator, when
+ enabled with the Set Beep Generation verb on NID 01h, or else from the
+ external PCBEEP pin) on the 1Ah pin node. When nonzero, expose the headphone
+ jack (or possibly Line In on some machines) input instead. If PC Beep is
+ selected, the 1Ah boost control has no effect.
+
+Amplify 1Ah loopback, left (L): 1 bit
+ Amplify the left channel of 1Ah before mixing it into outputs as specified

+
+Amplify 1Ah loopback, right (R): 1 bit
+ Amplify the right channel of 1Ah before mixing it into outputs as specified
+ by h and S bits. Does not affect the level of 1Ah exposed to other widgets.
+
+Loopback 1Ah to 21h [active low] (h): 1 bit
+ When zero, mix 1Ah (possibly with amplification, depending on L and R bits)
+ into 21h (headphone jack on my machine). Mixed signal respects the mute
+ setting on 21h.
+
+Loopback 1Ah to 14h (S): 1 bit
+ When one, mix 1Ah (possibly with amplification, depending on L and R bits)
+ into 14h (internal speaker on my machine). Mixed signal **ignores** the mute
+ setting on 14h and is present whenever 14h is configured as an output.

+
+Background
+==========
+
+All Realtek HDA codecs have a vendor-defined widget with node ID 20h which
+provides access to a bank of registers that control various codec functions.
+Registers are read and written via the standard HDA processing coefficient
+verbs (Set/Get Coefficient Index, Set/Get Processing Coefficient). The node is
+named "Realtek Vendor Registers" in public datasheets' verb listings and,
+apart from that, is entirely undocumented.
+
+This particular register, exposed at coefficient 0x36 and named in commits from
+Realtek, is of note: unlike most registers, which seem to control detailed
+amplifier parameters not in scope of the HDA specification, it controls audio
+routing which could just as easily have been defined using standard HDA mixer
+and selector widgets.
+
+Specifically, it selects between two sources for the input pin widget with Node
+ID (NID) 1Ah: the widget's signal can come either from an audio jack (on my
+laptop, a Dell XPS 13 9350, it's the headphone jack, but comments in Realtek
+commits indicate that it might be a Line In on some machines) or from the PC
+Beep line (which is itself multiplexed between the codec's internal beep
+generator and external PCBEEP pin, depending on if the beep generator is
+enabled via verbs on NID 01h). Additionally, it can mix (with optional
+amplification) that signal onto the 21h and/or 14h output pins.
+
+The register's reset value is 0x3717, corresponding to PC Beep on 1Ah that is
+then amplified and mixed into both the headphones and the speakers. Not only
+does this violate the HDA specification, which says that "[a vendor defined
+beep input pin] connection may be maintained *only* while the Link reset
+(**RST#**) is asserted", it means that we cannot ignore the register if we care
+about the input that 1Ah would otherwise expose or if the PCBEEP trace is
+poorly shielded and picks up chassis noise (both of which are the case on my
+machine).
+
+Unfortunately, there are lots of ways to get this register configuration wrong.
+Linux, it seems, has gone through most of them. For one, the register resets
+after S3 suspend: judging by existing code, this isn't the case for all vendor
+registers, and it's led to some fixes that improve behavior on cold boot but
+don't last after suspend. Other fixes have successfully switched the 1Ah input
+away from PC Beep but have failed to disable both loopback paths. On my
+machine, this means that the headphone input is amplified and looped back to
+the headphone output, which uses the exact same pins! As you might expect, this
+causes terrible headphone noise, the character of which is controlled by the
+1Ah boost control. (If you've seen instructions online to fix XPS 13 headphone
+noise by changing "Headphone Mic Boost" in ALSA, now you know why.)
+
+The information here has been obtained through black-box reverse engineering of
+the ALC256 codec's behavior and is not guaranteed to be correct. It likely
+also applies for the ALC255, ALC257, ALC235, and ALC236, since those codecs
+seem to be close relatives of the ALC256. (They all share one initialization
+function.) Additionally, other codecs like the ALC225 and ALC285 also have this
+register, judging by existing fixups in ``patch_realtek.c``, but specific
+data (e.g. node IDs, bit positions, pin mappings) for those codecs may differ
+from what I've described here.

+ DPAA FMan erratum A050385 software workaround implementation:
+ align buffers, data start, SG fragment length to avoid FMan DMA
+ splits.
+ FMAN DMA read or writes under heavy traffic load may cause FMAN
+ internal resource leak thus stopping further packet processing.
+ The FMAN internal queue can overflow when FMAN splits single
+ read or write transactions into multiple smaller transactions
+ such that more than 17 AXI transactions are in flight from FMAN
+ to interconnect. When the FMAN internal queue overflows, it can
+ stall further packet processing. The issue can occur with any
+ one of the following three conditions:
+ 1. FMAN AXI transaction crosses 4K address boundary (Errata
+ A010022)
+ 2. FMAN DMA address for an AXI transaction is not 16 byte
+ aligned, i.e. the last 4 bits of an address are non-zero
+ 3. Scatter Gather (SG) frames have more than one SG buffer in
+ the SG list and any one of the buffers, except the last
+ buffer in the SG list has data size that is not a multiple
+ of 16 bytes, i.e., other than 16, 32, 48, 64, etc.
+ With any one of the above three conditions present, there is
+ likelihood of stalled FMAN packet processing, especially under
+ stress with multiple ports injecting line-rate traffic.

+ * For mixer (0x64):
+ * * b selects an input channel (see below).
+ * * c selects an output channel pair (see below).
+ * * d selects left (0) or right (1) of that pair.
+ * * e 0-> disconnect, 0x01000000-> connect,
+ * 0x0109-> used for stereo-linking channels,
+ * e is also used for setting volume levels
+ * in which case b is also set so I guess
+ * this way it is possible to set the volume
+ * level from the specified input to the
+ * specified output.
+ *
+ * IN Channels:
+ * 0 - 7 Mic/Inst/Line (Analog inputs)
+ * 8 - 9 S/PDIF
+ * 10 - 17 ADAT
+ * 18 - 35 DAW (Inputs from the host)
+ *
+ * OUT Channels (pairs):
+ * 0 -> Main out
+ * 1 -> Line1/2
+ * 2 -> Line3/4
+ * 3 -> S/PDIF
+ * 4 -> ADAT?
+ *
+ * For device (0):
+ * * b and c are not used, at least not on the
+ * dumps I got.
+ * * d sets the control id to be modified
+ * (see below).
+ * * e sets the setting for that control.
+ * (so for the switches I was interested
+ * in it's 0/1)
+ *
+ * For output (0x65):
+ * * b is the output channel (see above).
+ * * c is zero.
+ * * e I guess the same as with mixer except 0x0109
