+==================================================
+QEMU and ACPI BIOS Generic Event Device interface
+==================================================
+
+The ACPI *Generic Event Device* (GED) is a HW reduced platform
+specific device introduced in ACPI v6.1 that handles all platform
+events, including the hotplug ones. GED is modelled as a device
+in the namespace with a _HID defined to be ACPI0013. This document
+describes the interface between QEMU and the ACPI BIOS.
+
+GED allows HW reduced platforms to handle interrupts in ACPI ASL
+statements. It follows a very similar approach to the _EVT method
+from GPIO events. All interrupts are listed in _CRS and the handler
+is written in _EVT method. However, the QEMU implementation uses a
+single interrupt for the GED device, relying on an IO memory region
+to communicate the type of device affected by the interrupt. This way,
+we can support up to 32 events with a unique interrupt.
+
+**Here is an example,**
+
+::
+
+ Device (\_SB.GED)
+ {
+ Name (_HID, "ACPI0013")
+ Name (_UID, Zero)
+ Name (_CRS, ResourceTemplate ()
+ {
+ Interrupt (ResourceConsumer, Edge, ActiveHigh, Exclusive, ,, )
+ {
+ 0x00000029,
+ }
+ })
+ OperationRegion (EREG, SystemMemory, 0x09080000, 0x04)
+ Field (EREG, DWordAcc, NoLock, WriteAsZeros)
+ {
+ ESEL, 32
+ }
+ Method (_EVT, 1, Serialized)
+ {
+ Local0 = ESEL // ESEL = IO memory region which specifies the
+ // device type.
+ If (((Local0 & One) == One))
+ {
+ MethodEvent1()
+ }
+ If ((Local0 & 0x2) == 0x2)
+ {
+ MethodEvent2()
+ }
+ ...
+ }
+ }
+
+GED IO interface (4 byte access)
+--------------------------------
+**read access:**
+
+::
+
+ [0x0-0x3] Event selector bit field (32 bit) set by QEMU.
+
+ bits:
+ 0: Memory hotplug event
+ 1: System power down event
+ 2-31: Reserved
+
+**write_access:**
+
+Nothing is expected to be written into GED IO memory

+ * This function performs quick remapping of an original file inode number
+ * on host to an appropriate different inode number on guest. This remapping
+ * of inodes is required to avoid inode nr collisions on guest which would
+ * happen if the 9p export contains more than 1 exported file system (or
+ * more than 1 file system data set), because unlike on host level where the
+ * files would have different device nrs, all files exported by 9p would
+ * share the same device nr on guest (the device nr of the virtual 9p device
+ * that is).
+ *
+ * Inode remapping is performed by chopping off high end bits of the original
+ * inode number from host, shifting the result upwards and then assigning a
+ * generated suffix number for the low end bits, where the same suffix number
+ * will be shared by all inodes with the same device id AND the same high end
+ * bits that have been chopped off. That approach utilizes the fact that inode
+ * numbers very likely share the same high end bits (i.e. due to their common
+ * sequential generation by file systems) and hence we only have to generate
+ * and track a very limited amount of suffixes in practice due to that.
+ *
+ * We generate variable size suffixes for that purpose. The 1st generated
+ * suffix will only have 1 bit and hence we only need to chop off 1 bit from
+ * the original inode number. The subsequent suffixes being generated will
+ * grow in (bit) size subsequently, i.e. the 2nd and 3rd suffix being
+ * generated will have 3 bits and hence we have to chop off 3 bits from their
+ * original inodes, and so on. That approach of using variable length suffixes
+ * (i.e. over fixed size ones) utilizes the fact that in practice only a very
+ * limited amount of devices are shared by the same export (e.g. typically
+ * less than 2 dozen devices per 9p export), so in practice we need to chop
+ * off less bits than with fixed size prefixes and yet are flexible to add
+ * new devices at runtime below host's export directory at any time without
+ * having to reboot guest nor requiring to reconfigure guest for that. And due
+ * to the very limited amount of original high end bits that we chop off that
+ * way, the total amount of suffixes we need to generate is less than by using
+ * fixed size prefixes and hence it also improves performance of the inode
+ * remapping algorithm, and finally has the nice side effect that the inode
+ * numbers on guest will be much smaller & human friendly. ;-)

+ * The ACPI Generic Event Device (GED) is a hardware-reduced specific
+ * device[ACPI v6.1 Section 5.6.9] that handles all platform events,
+ * including the hotplug ones. Generic Event Device allows platforms
+ * to handle interrupts in ACPI ASL statements. It follows a very
+ * similar approach like the _EVT method from GPIO events. All
+ * interrupts are listed in _CRS and the handler is written in _EVT
+ * method. Here, we use a single interrupt for the GED device, relying
+ * on IO memory region to communicate the type of device affected by
+ * the interrupt. This way, we can support up to 32 events with a
+ * unique interrupt.
+ *
+ * Here is an example.
+ *
+ * Device (\_SB.GED)
+ * {
+ * Name (_HID, "ACPI0013")
+ * Name (_UID, Zero)
+ * Name (_CRS, ResourceTemplate ()
+ * {

+ * Field (EREG, DWordAcc, NoLock, WriteAsZeros)
+ * {
+ * ESEL, 32
+ * }
+ *
+ * Method (_EVT, 1, Serialized) // _EVT: Event
+ * {
+ * Local0 = ESEL // ESEL = IO memory region which specifies the
+ * // device type.

Specifies the tag name to be used by the guest to mount this export point.
+@item multidevs=@var{multidevs}
+Specifies how to deal with multiple devices being shared with a 9p export.
+Supported behaviours are either "remap", "forbid" or "warn". The latter is
+the default behaviour on which virtfs 9p expects only one device to be
+shared with the same export, and if more than one device is shared and
+accessed via the same 9p export then only a warning message is logged
+(once) by qemu on host side. In order to avoid file ID collisions on guest
+you should either create a separate virtfs export for each device to be
+shared with guests (recommended way) or you might use "remap" instead which
+allows you to share multiple devices with only one export instead, which is
+achieved by remapping the original inode numbers from host to guest in a
+way that would prevent such collisions. Remapping inodes in such use cases
+is required because the original device IDs from host are never passed and
+exposed on guest. Instead all files of an export shared with virtfs always
+share the same device id on guest. So two files with identical inode
+numbers but from actually different devices on host would otherwise cause a
+file ID collision and hence potential misbehaviours on guest. "forbid" on
+the other hand assumes like "warn" that only one device is shared by the
+same export, however it will not only log a warning message but also
+deny access to additional devices on guest. Note though that "forbid" does
+currently not block all possible file access operations (e.g. readdir()
+would still return entries from other devices).

+/*
+ * How to add or update the tests:
+ * Contributor:
+ * 1. add empty files for new tables, if any, under tests/data/acpi
+ * 2. list any changed files in tests/bios-tables-test-allowed-diff.h
+ * 3. commit the above *before* making changes that affect the tables
+ * Maintainer:
+ * After 1-3 above tests will pass but ignore differences with the expected files.
+ * You will also notice that tests/bios-tables-test-allowed-diff.h lists
+ * a bunch of files. This is your hint that you need to do the below:
+ * 4. Run
+ * make check V=1
+ * this will produce a bunch of warnings about differences
+ * beween actual and expected ACPI tables. If you have IASL installed,
+ * they will also be disassembled so you can look at the disassembled
+ * output. If not - disassemble them yourself in any way you like.
+ * Look at the differences - make sure they make sense and match what the
+ * changes you are merging are supposed to do.
+ *
+ * 5. From build directory, run:
+ * $(SRC_PATH)/tests/data/acpi/rebuild-expected-aml.sh
+ * 6. Now commit any changes.
+ * 7. Before doing a pull request, make sure tests/bios-tables-test-allowed-diff.h
+ * is empty - this will ensure following changes to ACPI tables will
+ * be noticed.
