A subsequent patch to add support for setting linkspeed/duplex in
virtio-net, requires a few definitions from ethtool.h, which ends up
pulling in kernel.h and sysinfo.h as well.

+ * @supported: Bitmask of %SUPPORTED_* flags for the link modes,
+ * physical connectors and other link features for which the
+ * interface supports autonegotiation or auto-detection.
+ * Read-only.
+ * @advertising: Bitmask of %ADVERTISED_* flags for the link modes,
+ * physical connectors and other link features that are
+ * advertised through autonegotiation or enabled for
+ * auto-detection.
+ * @speed: Low bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
+ * @duplex: Duplex mode; one of %DUPLEX_*
+ * @port: Physical connector type; one of %PORT_*
+ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
+ * applicable. For clause 45 PHYs this is the PRTAD.
+ * @transceiver: Historically used to distinguish different possible
+ * PHY types, but not in a consistent way. Deprecated.
+ * @autoneg: Enable/disable autonegotiation and auto-detection;
+ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
+ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
+ * protocols supported by the interface; 0 if unknown.
+ * Read-only.
+ * @maxtxpkt: Historically used to report TX IRQ coalescing; now
+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
+ * @maxrxpkt: Historically used to report RX IRQ coalescing; now
+ * obsoleted by &struct ethtool_coalesce. Read-only; deprecated.
+ * @speed_hi: High bits of the speed, 1Mb units, 0 to INT_MAX or SPEED_UNKNOWN
+ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
+ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
+ * value will be %ETH_TP_MDI_INVALID. Read-only.
+ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
+ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if
+ * necessary.
+ * @lp_advertising: Bitmask of %ADVERTISED_* flags for the link modes
+ * and other link features that the link partner advertised
+ * through autonegotiation; 0 if unknown or not applicable.
+ * Read-only.
+ *
+ * The link speed in Mbps is split between @speed and @speed_hi. Use
+ * the ethtool_cmd_speed() and ethtool_cmd_speed_set() functions to
+ * access it.
+ *
+ * If autonegotiation is disabled, the speed and @duplex represent the
+ * fixed link mode and are writable if the driver supports multiple
+ * link modes. If it is enabled then they are read-only; if the link
+ * is up they represent the negotiated link mode; if the link is down,
+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical
+ * connectors fitted or do not allow the driver to detect which are
+ * fitted. For these interfaces @port and/or @phy_address may be
+ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
+ * Otherwise, attempts to write different values may be ignored or
+ * rejected.
+ *
+ * Users should assume that all fields not marked read-only are
+ * writable and subject to validation by the driver. They should use
+ * %ETHTOOL_GSET to get the current values before making specific
+ * changes and then applying them with %ETHTOOL_SSET.
+ *
+ * Drivers that implement set_settings() should validate all fields
+ * other than @cmd that are not described as read-only or deprecated,
+ * and must ignore all fields described as read-only.
+ *
+ * Deprecated fields should be ignored by both users and drivers.

+ * settings; do not use %ETHTOOL_SSET if %ETHTOOL_GLINKSETTINGS
+ * succeeded: stick to %ETHTOOL_GLINKSETTINGS/%SLINKSETTINGS in

+ * settings; do not use %ETHTOOL_SLINKSETTINGS if
+ * %ETHTOOL_GLINKSETTINGS failed: stick to
+ * %ETHTOOL_GSET/%ETHTOOL_SSET in that case.
+ *
+ * @cmd: Command number = %ETHTOOL_GLINKSETTINGS or %ETHTOOL_SLINKSETTINGS
+ * @speed: Link speed (Mbps)
+ * @duplex: Duplex mode; one of %DUPLEX_*
+ * @port: Physical connector type; one of %PORT_*
+ * @phy_address: MDIO address of PHY (transceiver); 0 or 255 if not
+ * applicable. For clause 45 PHYs this is the PRTAD.
+ * @autoneg: Enable/disable autonegotiation and auto-detection;
+ * either %AUTONEG_DISABLE or %AUTONEG_ENABLE
+ * @mdio_support: Bitmask of %ETH_MDIO_SUPPORTS_* flags for the MDIO
+ * protocols supported by the interface; 0 if unknown.
+ * Read-only.
+ * @eth_tp_mdix: Ethernet twisted-pair MDI(-X) status; one of
+ * %ETH_TP_MDI_*. If the status is unknown or not applicable, the
+ * value will be %ETH_TP_MDI_INVALID. Read-only.
+ * @eth_tp_mdix_ctrl: Ethernet twisted pair MDI(-X) control; one of
+ * %ETH_TP_MDI_*. If MDI(-X) control is not implemented, reads
+ * yield %ETH_TP_MDI_INVALID and writes may be ignored or rejected.
+ * When written successfully, the link should be renegotiated if
+ * necessary.
+ * @link_mode_masks_nwords: Number of 32-bit words for each of the
+ * supported, advertising, lp_advertising link mode bitmaps. For
+ * %ETHTOOL_GLINKSETTINGS: on entry, number of words passed by user
+ * (>= 0); on return, if handshake in progress, negative if
+ * request size unsupported by kernel: absolute value indicates
+ * kernel expected size and all the other fields but cmd
+ * are 0; otherwise (handshake completed), strictly positive
+ * to indicate size used by kernel and cmd field stays
+ * %ETHTOOL_GLINKSETTINGS, all other fields populated by driver. For
+ * %ETHTOOL_SLINKSETTINGS: must be valid on entry, ie. a positive
+ * value returned previously by %ETHTOOL_GLINKSETTINGS, otherwise
+ * refused. For drivers: ignore this field (use kernel's
+ * __ETHTOOL_LINK_MODE_MASK_NBITS instead), any change to it will
+ * be overwritten by kernel.
+ * @supported: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features for which the interface
+ * supports autonegotiation or auto-detection. Read-only.
+ * @advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, physical
+ * connectors and other link features that are advertised through
+ * autonegotiation or enabled for auto-detection.
+ * @lp_advertising: Bitmap with each bit meaning given by
+ * %ethtool_link_mode_bit_indices for the link modes, and other
+ * link features that the link partner advertised through
+ * autonegotiation; 0 if unknown or not applicable. Read-only.
+ * @transceiver: Used to distinguish different possible PHY types,
+ * reported consistently by PHYLIB. Read-only.
+ *
+ * If autonegotiation is disabled, the speed and @duplex represent the
+ * fixed link mode and are writable if the driver supports multiple
+ * link modes. If it is enabled then they are read-only; if the link
+ * is up they represent the negotiated link mode; if the link is down,
+ * the speed is 0, %SPEED_UNKNOWN or the highest enabled speed and
+ * @duplex is %DUPLEX_UNKNOWN or the best enabled duplex mode.
+ *
+ * Some hardware interfaces may have multiple PHYs and/or physical
+ * connectors fitted or do not allow the driver to detect which are
+ * fitted. For these interfaces @port and/or @phy_address may be
+ * writable, possibly dependent on @autoneg being %AUTONEG_DISABLE.
+ * Otherwise, attempts to write different values may be ignored or
+ * rejected.
+ *
+ * Deprecated %ethtool_cmd fields transceiver, maxtxpkt and maxrxpkt
+ * are not available in %ethtool_link_settings. Until all drivers are
+ * converted to ignore them or to the new %ethtool_link_settings API,
+ * for both queries and changes, users should always try
+ * %ETHTOOL_GLINKSETTINGS first, and if it fails with -ENOTSUPP stick
+ * only to %ETHTOOL_GSET and %ETHTOOL_SSET consistently. If it
+ * succeeds, then users should stick to %ETHTOOL_GLINKSETTINGS and
+ * %ETHTOOL_SLINKSETTINGS (which would support drivers implementing
+ * either %ethtool_cmd or %ethtool_link_settings).
+ *
+ * Users should assume that all fields not marked read-only are
+ * writable and subject to validation by the driver. They should use
+ * %ETHTOOL_GLINKSETTINGS to get the current values before making specific
+ * changes and then applying them with %ETHTOOL_SLINKSETTINGS.
+ *
+ * Drivers that implement %get_link_ksettings and/or
+ * %set_link_ksettings should ignore the @cmd
+ * and @link_mode_masks_nwords fields (any change to them overwritten
+ * by kernel), and rely only on kernel's internal
+ * %__ETHTOOL_LINK_MODE_MASK_NBITS and
+ * %ethtool_link_mode_mask_t. Drivers that implement
+ * %set_link_ksettings() should validate all fields other than @cmd
+ * and @link_mode_masks_nwords that are not described as read-only or
+ * deprecated, and must ignore all fields described as read-only.

In prepartion for using some of the high order feature bits, make sure that
virtio-net uses 64-bit values everywhere.

From: Jason Baron <jbaron@akamai.com>
Although linkspeed and duplex can be set in a linux guest via 'ethtool -s',
this requires custom ethtool commands for virtio-net by default.
Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows
the hypervisor to export a linkspeed and duplex setting. The user can
subsequently overwrite it later if desired via: 'ethtool -s'.
Linkspeed and duplex settings can be set as:
'-device virtio-net,speed=10000,duplex=full'
where speed is [0...INT_MAX], and duplex is ["half"|"full"].

SeaBIOS blob which is currently shipped with QEMU
doesn't need acpi-dsdt.aml nor is able to use it
and code that loaded it in QEMU was removed by
(commit 9fb7aaaf4c "pc: drop external DSDT loading")
in 2013.

that initializes 'obj' now.

it will help to add Generic Address Structure to ACPI tables
without using packed C structures and avoid endianness
issues as API doesn't need an explicit conversion.

From: Igor Mammedov <imammedo@redhat.com>
move FADT data initialization out of fadt_setup() into dedicated
init_fadt_data() that will set common for pc/q35 values in
AcpiFadtData structure and acpi_get_pm_info() will complement
it with pc/q35 specific values initialization.
That will allow to get rid of fadt_setup() and generalize
build_fadt() so it could be easily extended for rev5 and
reused by ARM target.
While at it also move facs/dsdt/xdsdt offsets from build_fadt()
arg list into AcpiFadtData, as they belong to the same dataset.

From: Igor Mammedov <imammedo@redhat.com>
build_append_foo() API doesn't need explicit endianness
conversions which eliminates a source of errors and
it makes build_fadt() look like declarative definition of
FADT table in ACPI spec, which makes it easy to review.
Also it allows easily extending FADT to support other
revisions which will be used by follow up patches
where build_fadt() will be reused for ARM target.

It will be extended and reused by follow up patch for ARM target.
PS:
Since it's generic function now, don't patch FIRMWARE_CTRL, DSDT
fields if they don't point to tables since platform might not
provide them and use X_ variants instead if applicable.

Extend generic build_fadt() to support rev5.1 FADT
and reuse it for 'virt' board, it would allow to
phase out usage of AcpiFadtDescriptorRev5_1 and
later ACPI_FADT_COMMON_DEF.

there is no point to read fields here but not actually
checking them so drop it and read only header + dsdt/facs
addresses since it's needed later to fetch that tables.
With this cleanup we can get rid of AcpiFadtDescriptorRev3/
ACPI_FADT_COMMON_DEF which have no users left.

Used_memslots is shared by vhost kernel and user, it is equal to
dev->mem->nregions, which is correct for vhost kernel, but not for
vhost user, the latter one uses memory regions that have file
descriptor. E.g. a VM has a vhost-user NIC and 8(vhost user memslot
upper limit) memory slots, it will be failed to hotplug a new DIMM
device since vhost_has_free_slot() finds no free slot left. It
should be successful if only part of memory slots have file
descriptor, so setting used memslots for vhost-user and
vhost-kernel respectively.

From: Haozhong Zhang <haozhong.zhang@intel.com>
Make qmp_pc_dimm_device_list() return sorted by start address
list of devices so that it could be reused in places that
would need sorted list*. Reuse existing pc_dimm_built_list()
to get sorted list.
While at it hide recursive callbacks from callers, so that:
qmp_pc_dimm_device_list(qdev_get_machine(), &list);
could be replaced with simpler:
list = qmp_pc_dimm_device_list();
* follow up patch will use it in build_srat()

From: Haozhong Zhang <haozhong.zhang@intel.com>
It may need to treat PC-DIMM and NVDIMM differently, e.g., when
deciding the necessity of non-volatile flag bit in SRAT memory
affinity structures.
A new field 'nvdimm' is added to the union type MemoryDeviceInfo for
such purpose. Its type is currently PCDIMMDeviceInfo and will be
updated when necessary in the future.
It also fixes "info memory-devices"/query-memory-devices which
currently show nvdimm devices as dimm devices since
object_dynamic_cast(obj, TYPE_PC_DIMM) happily cast nvdimm to
TYPE_PC_DIMM which it's been inherited from.

From: Haozhong Zhang <haozhong.zhang@intel.com>
ACPI 6.2A Table 5-129 "SPA Range Structure" requires the proximity
domain of a NVDIMM SPA range must match with corresponding entry in
SRAT table.
The address ranges of vNVDIMM in QEMU are allocated from the
hot-pluggable address space, which is entirely covered by one SRAT
memory affinity structure. However, users can set the vNVDIMM
proximity domain in NFIT SPA range structure by the 'node' property of
'-device nvdimm' to a value different than the one in the above SRAT
memory affinity structure.
In order to solve such proximity domain mismatch, this patch builds
one SRAT memory affinity structure for each DIMM device present at
boot time, including both PC-DIMM and NVDIMM, with the proximity
domain specified in '-device pc-dimm' or '-device nvdimm'.
The remaining hot-pluggable address space is covered by one or multiple
SRAT memory affinity structures with the proximity domain of the last
node as before.

From: Haozhong Zhang <haozhong.zhang@intel.com>
QEMU now builds one SRAT memory affinity structure for each PC-DIMM
and NVDIMM device presented at boot time with the proximity domain
specified in the device option 'node', rather than only one SRAT
memory affinity structure covering the entire hotpluggable address
space with the proximity domain of the last node.
Add test cases on PC and Q35 machines with 4 proximity domains, and
one PC-DIMM and one NVDIMM attached to the 2nd and 3rd proximity
domains respectively. Check whether the QEMU-built SRAT tables match
with the expected ones.
The following ACPI tables need to be added for this test:
tests/acpi-test-data/pc/APIC.dimmpxm
tests/acpi-test-data/pc/DSDT.dimmpxm
tests/acpi-test-data/pc/NFIT.dimmpxm
tests/acpi-test-data/pc/SRAT.dimmpxm

tests/acpi-test-data/q35/NFIT.dimmpxm
tests/acpi-test-data/q35/SRAT.dimmpxm
tests/acpi-test-data/q35/SSDT.dimmpxm
New APIC and DSDT are needed because of the multiple processors
configuration. New NFIT and SSDT are needed because of NVDIMM.
