+/* Sun4v hypervisor interfaces and defines.
+ *
+ * Hypervisor calls are made via traps to software traps number 0x80
+ * and above. Registers %o0 to %o5 serve as argument, status, and
+ * return value registers.
+ *
+ * There are two kinds of these traps. First there are the normal
+ * "fast traps" which use software trap 0x80 and encode the function
+ * to invoke by number in register %o5. Argument and return value
+ * handling is as follows:
+ *
+ * -----------------------------------------------
+ * | %o5 | function number | undefined |
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * The second type are "hyper-fast traps" which encode the function
+ * number in the software trap number itself. So these use trap
+ * numbers > 0x80. The register usage for hyper-fast traps is as
+ * follows:
+ *
+ * -----------------------------------------------
+ * | %o0 | argument 0 | return status |
+ * | %o1 | argument 1 | return value 1 |
+ * | %o2 | argument 2 | return value 2 |
+ * | %o3 | argument 3 | return value 3 |
+ * | %o4 | argument 4 | return value 4 |
+ * -----------------------------------------------
+ *
+ * Registers providing explicit arguments to the hypervisor calls
+ * are volatile across the call. Upon return their values are
+ * undefined unless explicitly specified as containing a particular
+ * return value by the specific call. The return status is always
+ * returned in register %o0, zero indicates a successful execution of
+ * the hypervisor call and other values indicate an error status as
+ * defined below. So, for example, if a hyper-fast trap takes
+ * arguments 0, 1, and 2, then %o0, %o1, and %o2 are volatile across
+ * the call and %o3, %o4, and %o5 would be preserved.
+ *
+ * If the hypervisor trap is invalid, or the fast trap function number
+ * is invalid, HV_EBADTRAP will be returned in %o0. Also, all 64-bits
+ * of the argument and return values are significant.

+ *
+ * tsbnum TSB number. Indentifies which io-tsb is used.
+ * For this version of the specification, tsbnum
+ * must be zero.
+ *
+ * tsbindex TSB index. Identifies which entry in the TSB
+ * is used. The first entry is zero.
+ *
+ * tsbid A 64-bit aligned data structure which contains
+ * a tsbnum and a tsbindex. Bits 63:32 contain the
+ * tsbnum and bits 31:00 contain the tsbindex.
+ *
+ * Use the HV_PCI_TSBID() macro to construct such
+ * values.
+ *
+ * io_attributes IO attributes for IOMMU mappings. One of more
+ * of the attritbute bits are stores in a 64-bit
+ * value. The values are defined below.
+ *
+ * r_addr 64-bit real address
+ *
+ * pci_device PCI device address. A PCI device address identifies
+ * a specific device on a specific PCI bus segment.
+ * A PCI device address ia a 32-bit unsigned integer
+ * with the following format:
+ *
+ * 00000000.bbbbbbbb.dddddfff.00000000
+ *
+ * Use the HV_PCI_DEVICE_BUILD() macro to construct
+ * such values.
+ *
+ * pci_config_offset
+ * PCI configureation space offset. For conventional
+ * PCI a value between 0 and 255. For extended
+ * configuration space, a value between 0 and 4095.
+ *
+ * Note: For PCI configuration space accesses, the offset
+ * must be aligned to the access size.
+ *
+ * error_flag A return value which specifies if the action succeeded
+ * or failed. 0 means no error, non-0 means some error
+ * occurred while performing the service.
+ *
+ * io_sync_direction
+ * Direction definition for pci_dma_sync(), defined
+ * below in HV_PCI_SYNC_*.
+ *
+ * io_page_list A list of io_page_addresses, an io_page_address is
+ * a real address.
+ *
+ * io_page_list_p A pointer to an io_page_list.
+ *
+ * "size based byte swap" - Some functions do size based byte swapping
+ * which allows sw to access pointers and
+ * counters in native form when the processor
+ * operates in a different endianness than the

+ * What is struct pid?
+ *
+ * A struct pid is the kernel's internal notion of a process identifier.
+ * It refers to individual tasks, process groups, and sessions. While
+ * there are processes attached to it the struct pid lives in a hash
+ * table, so it and then the processes that it refers to can be found
+ * quickly from the numeric pid value. The attached processes may be
+ * quickly accessed by following pointers from struct pid.
+ *
+ * Storing pid_t values in the kernel and refering to them later has a
+ * problem. The process originally with that pid may have exited and the
+ * pid allocator wrapped, and another process could have come along
+ * and been assigned that pid.
+ *
+ * Referring to user space processes by holding a reference to struct
+ * task_struct has a problem. When the user space process exits
+ * the now useless task_struct is still kept. A task_struct plus a
+ * stack consumes around 10K of low kernel memory. More precisely
+ * this is THREAD_SIZE + sizeof(struct task_struct). By comparison
+ * a struct pid is about 64 bytes.
+ *
+ * Holding a reference to struct pid solves both of these problems.
+ * It is small so holding a reference does not consume a lot of
+ * resources, and since a new struct pid is allocated when the numeric
+ * pid value is reused we don't mistakenly refer to new processes.

+ * RPC client per-operation statistics provide latency and retry

+ * These statistics are not for detailed problem diagnosis, but simply
+ * to indicate whether the problem is local or remote.
+ *
+ * These counters are not meant to be human-readable, but are meant to be
+ * integrated into system monitoring tools such as "sar" and "iostat". As
+ * such, the counters are sampled by the tools over time, and are never
+ * zeroed after a file system is mounted. Moving averages can be computed
+ * by the tools by taking the difference between two instantaneous samples
+ * and dividing that by the time between the samples.
+ *
+ * The counters are maintained in a single array per RPC client, indexed
+ * by procedure number. There is no need to maintain separate counter
+ * arrays per-CPU because these counters are always modified behind locks.

+/* msp3400 routing
+ ===============
+
+ The msp3400 has a complicated routing scheme with many possible
+ combinations. The details are all in the datasheets but I will try
+ to give a short description here.
+
+ Inputs
+ ======
+
+ There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+ to select which tuner input to use and which SCART input to use. The
+ selected tuner input, the selected SCART input and all I2S inputs go to
+ the DSP (the tuner input first goes through the demodulator).
+
+ The DSP handles things like volume, bass/treble, balance, and some chips
+ have support for surround sound. It has several outputs: MAIN, AUX, I2S
+ and SCART1/2. Each output can select which DSP input to use. So the MAIN
+ output can select the tuner input while at the same time the SCART1 output
+ uses the I2S input.
+
+ Outputs
+ =======
+
+ Most DSP outputs are also the outputs of the msp3400. However, the SCART
+ outputs of the msp3400 can select which input to use: either the SCART1 or
+ SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+ bypassing the DSP.
+
+ Summary
+ =======
+
+ So to specify a complete routing scheme for the msp3400 you will have to
+ specify in the 'input' field of the v4l2_routing struct:
+
+ 1) which tuner input to use
+ 2) which SCART input to use
+ 3) which DSP input to use for each DSP output
+
+ And in the 'output' field of the v4l2_routing struct you specify:
+
+ 1) which SCART input to use for each SCART output
+
+ Depending on how the msp is wired to the other components you can
+ ignore or mute certain inputs or outputs.
+
+ Also, depending on the msp version only a subset of the inputs or
+ outputs may be present. At the end of this header some tables are
+ added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+ 1) the tuner (SIF) input
+ 2) the SCART input
+ Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+ input, bits 4-7 are reserved.

+
+ The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+ (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+ There also is a quasi-peak detector output, but that is not used by
+ this driver and is set to the same input as the loudspeaker output.
+ Not all outputs are supported by all msp models. Setting the input
+ of an unsupported output will be ignored by the driver.
+
+ There are up to 16 DSP inputs to choose from, so each output is
+ assigned 4 bits.
+
+ Note: the 44x8G can mix two inputs and feed the result back to the
+ DSP. This is currently not implemented. Also not implemented is the
