Add ACPI DSDT tables for q35 that are being updated by the next patch
The following patch ("piix4: don't reserve hw resources when
hotplug is off globally") modifies certain ACPI tables for q35 machines.
This patch adds those table names to tests/qtest/bios-tables-test-allowed-diff.h
so that unit tests continue to pass and bisection is not broken.

tests/acpi: add newly added acpi DSDT table blob for pci bridge hotplug flag
This patch adds a binary blob corresponding to the DSDT acpi table. It is used
to unit test the flag 'acpi-pci-hotplug-with-bridge-support' used with pci
bridges.
This change also clears the file tests/qtest/bios-tables-test-allowed-diff.h
so that future changes which affect the table can be caught.
The following is the diff between files tests/data/acpi/pc/DSDT.bridge and
tests/data/acpi/pc/DSDT.hpbridge after disassembly :

i440fx/acpi: do not add hotplug related amls for cold plugged bridges
Cold plugged bridges are not hot unpluggable, even when their hotplug
property (acpi-pci-hotplug-with-bridge-support) is turned off. Please see
the function acpi_pcihp_pc_no_hotplug(). However, with
the current implementaton, Windows would try to hot-unplug a pci bridge when
it's hotplug switch is off. This is regardless of whether there are devices
attached to the bridge. This is because we add ACPI code like _EJ0 etc for the
pci slot where the bridge is cold plugged.
In this fix, we identify a cold plugged bridge and for cold plugged bridges,
we do not add the appropriate ACPI methods that are used by the OS
to identify a hot-pluggable/unpluggable pci device. After this change, Windows
does not detect the cold plugged pci bridge as ejectable.
As a result of the patch, the following are the changes to the DSDT ACPI
table:

hw/smbios: report error if table size is too large
The SMBIOS 2.1 entry point uses a uint16 data type for reporting the total length of the tables. If the user passes -smbios configuration to QEMU that causes the table size to exceed this limit then various bad behaviours result, including - firmware hangs in an infinite loop - firmware triggers a KVM crash on bad memory access - firmware silently discards user's SMBIOS data replacing it with a generic data set. Limiting the size to 0xffff in QEMU avoids triggering most of these problems. There is a remaining bug in SeaBIOS which tries to prepend its own data for table 0, and does not check whether there is sufficient space before attempting this.

hw/smbios: support loading OEM strings values from a file
Some applications want to pass quite large values for the OEM strings

be better to load them from a file, as supported with -fw_cfg.
This introduces the "path" parameter allowing for:
$ echo -n "thisthing" > mydata.txt
$ qemu-system-x86_64 \
-smbios type=11,value=something \
-smbios type=11,path=mydata.txt \
-smbios type=11,value=somemore \

$ dmidecode -t 11

x68: acpi: trigger SMI before sending hotplug Notify event to OSPM
In case firmware has negotiated CPU hotplug SMI feature, generate AML to describe SMI IO port region and send SMI to firmware on each CPU hotplug SCI in case new CPUs were hotplugged. Since new CPUs can be hotplugged while CPU_SCAN_METHOD is running we can't send SMI before new CPUs are fetched from QEMU as it could cause sending Notify to a CPU that firmware hasn't seen yet. So fetch new CPUs into local cache first, then send SMI and after that send Notify events to cached CPUs. This should ensure that Notify is sent only to CPUs which were processed by firmware first. Any CPUs that were hotplugged after caching will be processed by the next CPU_SCAN_METHOD, when pending SCI is handled.

x86: cpuhp: refuse cpu hot-unplug request earlier if not supported
CPU hot-unplug with SMM requires firmware participation to prevent guest crash (i.e. CPU can be removed only after OS _and_ firmware were prepared for the action). Previous patches introduced ICH9_LPC_SMI_F_CPU_HOT_UNPLUG_BIT feature bit, which is advertised by firmware when it has support for CPU hot-unplug. Use it to check if guest is able to handle unplug and make device_del fail gracefully if hot-unplug feature hasn't been negotiated.

x86: cpuhp: prevent guest crash on CPU hotplug when broadcast SMI is in use
There were reports of guest crash on CPU hotplug, when using q35 machine type and OVMF with SMM, due to hotplugged CPU trying to process SMI at default SMI handler location without it being relocated by firmware first.

It will allow firmware to notify QEMU that firmware requires SMI being triggered on CPU hot[un]plug, so that it would be able to account for hotplugged CPU and relocate it to new SMM base and/or safely remove CPU on unplug.

not bad features. However the guest can still trigger the access of the

vhost: recheck dev state in the vhost_migration_log routine
vhost-user devices can get a disconnect in the middle of the VHOST-USER
handshake on the migration start. If disconnect event happened right
before sending next VHOST-USER command, then the vhost_dev_set_log()
call in the vhost_migration_log() function will return error. This error
will lead to the assert() and close the QEMU migration source process.
For the vhost-user devices the disconnect event should not break the
migration process, because:
- the device will be in the stopped state, so it will not be changed
during migration
- if reconnect will be made the migration log will be reinitialized as
part of reconnect/init process:
#0 vhost_log_global_start (listener=0x563989cf7be0)

#1 0x000056398603d8bc in listener_add_address_space (listener=0x563989cf7be0,

#3 0x0000563985fd6956 in vhost_dev_init (hdev=0x563989cf7bd8,
opaque=0x563989cf7e30, backend_type=VHOST_BACKEND_TYPE_USER,
busyloop_timeout=0)
at hw/virtio/vhost.c:1385
#4 0x0000563985f7d0b8 in vhost_user_blk_connect (dev=0x563989cf7990)

#5 0x0000563985f7d3f6 in vhost_user_blk_event (opaque=0x563989cf7990,
event=CHR_EVENT_OPENED)
at hw/block/vhost-user-blk.c:379
Update the vhost-user-blk device with the internal started_vu field which
will be used for initialization (vhost_user_blk_start) and clean up
(vhost_user_blk_stop). This additional flag in the VhostUserBlk structure
will be used to track whether the device really needs to be stopped and
cleaned up on a vhost-user level.
The disconnect event will set the overall VHOST device (not vhost-user) to
the stopped state, so it can be used by the general vhost_migration_log
routine.
Such approach could be propogated to the other vhost-user devices, but
better idea is just to make the same connect/disconnect code for all the
vhost-user devices.

vhost-vdpa: batch updating IOTLB mappings
To speed up the memory mapping updating between vhost-vDPA and vDPA device driver, this patch passes the IOTLB batching flags via IOTLB API. Two new flags was introduced, VHOST_IOTLB_BATCH_BEGIN is a hint that a bathced IOTLB updating may be initiated from the userspace. VHOST_IOTLB_BATCH_END is a hint that userspace has finished the updating: VHOST_IOTLB_BATCH_BEGIN VHOST_IOTLB_UPDATE/VHOST_IOTLB_INVALIDATE ... VHOST_IOTLB_BATCH_END Vhost-vDPA can then know that all mappings has been set and can do optimization like passing all the mappings to the vDPA device driver.

vhost: switch to use IOTLB v2 format
This patch tries to switch to use new kernel IOTLB format V2. Previous
version may have inconsistent ABI between 32bit and 64bit machines
because of the hole after type field. Refer kernel commit
("429711aec282 vhost: switch to use new message format") for more
information.
To enable this feature, qemu need to use a new ioctl
VHOST_SET_BACKEND_FEATURE with VHOST_BACKEND_F_IOTLB_MSG_V2 bit. A new
vhost setting backend features ops was introduced. And when we try to
set features for vhost dev, we will examine the support of new IOTLB
format and enable it. This process is total transparent to guest,
which means we can have different IOTLB message type in src and dst
during migration.
The conversion of IOTLB message is straightforward, just check the
type and behave accordingly.

virtiofsd: Used glib "shared" thread pool
glib offers thread pools and it seems to support "exclusive" and "shared" thread pools. https://developer.gnome.org/glib/stable/glib-Thread-Pools.html#g-thread-pool-new Currently we use "exlusive" thread pools but its performance seems to be poor. I tried using "shared" thread pools and performance seems much better. I posted performance results here. https://www.redhat.com/archives/virtio-fs/2020-September/msg00080.html So lets switch to shared thread pools. We can think of making it optional once somebody can show in what cases exclusive thread pools offer better results. For now, my simple performance tests across the board see better results with shared thread pools.
