NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)
Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info
- MEM DEV structure, it has the @handle which is used to associate specified
ACPI NVDIMM device we will introduce in later patch.
Also we can happily ignored the memory device's interleave, the real
nvdimm hardware access is hidden behind host
- DCR structure, it defines vendor ID used to associate specified vendor
nvdimm driver. Since we only implement PMEM mode this time, Command
window and Data window are not needed
The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \
memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \
nvdimm,memdev=mem1,id=nv1
It is disabled on default

Make use of the QCryptoSecret object to support loading of
encrypted x509 keys. The optional 'passwordid' parameter
to the tls-creds-x509 object type, provides the ID of a
secret object instance that holds the decryption password
for the PEM file.
# printf "123456" > mypasswd.txt
# $QEMU \
-object secret,id=sec0,filename=mypasswd.txt \
-object tls-creds-x509,passwordid=sec0,id=creds0,\
dir=/home/berrange/.pki/qemu,endpoint=server \
-vnc :1,tls-creds=creds0
This requires QEMU to be linked to GNUTLS >= 3.1.11. If
GNUTLS is too old an error will be reported if an attempt
is made to pass a decryption password.

Introduce a new QCryptoSecret object class which will be used
for providing passwords and keys to other objects which need
sensitive credentials.
The new object can provide secret values directly as properties,
or indirectly via a file. The latter includes support for file
descriptor passing syntax on UNIX platforms. Ordinarily passing
secret values directly as properties is insecure, since they
are visible in process listings, or in log files showing the
CLI args / QMP commands. It is possible to use AES-256-CBC to
encrypt the secret values though, in which case all that is
visible is the ciphertext. For ad hoc developer testing though,
it is fine to provide the secrets directly without encryption
so this is not explicitly forbidden.
The anticipated scenario is that libvirtd will create a random
master key per QEMU instance (eg /var/run/libvirt/qemu/$VMNAME.key)
and will use that key to encrypt all passwords it provides to
QEMU via '-object secret,....'. This avoids the need for libvirt
(or other mgmt apps) to worry about file descriptor passing.
It also makes life easier for people who are scripting the
management of QEMU, for whom FD passing is significantly more
complex.
Providing data inline (insecure, only for ad hoc dev testing)
$QEMU -object secret,id=sec0,data=letmein
Providing data indirectly in raw format
printf "letmein" > mypasswd.txt
$QEMU -object secret,id=sec0,file=mypasswd.txt
Providing data indirectly in base64 format
$QEMU -object secret,id=sec0,file=mykey.b64,format=base64
Providing data with encryption
$QEMU -object secret,id=master0,file=mykey.b64,format=base64 \
-object secret,id=sec0,data=[base64 ciphertext],\
keyid=master0,iv=[base64 IV],format=base64
Note that 'format' here refers to the format of the ciphertext
data. The decrypted data must always be in raw byte format.
More examples are shown in the updated docs.

bs->options doesn't only contain options that the user explicitly
requested, but also option that were derived from flags, the filename or
inherited from the parent node.
For reopen, it is important to know the difference because reopening the
parent can change inherited values in child nodes, but it shouldn't
change any options that were explicitly specified for the child.

In order to decide whether a blkdebug: filename can be produced or a
json: one is necessary, blkdebug checked whether bs->options had more
options than just "config", "x-image" or "image" (the latter including
nested options). That doesn't work well when generic block layer options
are present.
This patch passes an option QDict to the driver that contains only
driver-specific options, i.e. the options for the general block layer as
well as child nodes are already filtered out. Works much better this
way.

qcow2 accepts a few driver-specific options that overlap semantically
(e.g. "overlap-check" is an alias of "overlap-check.template", and any
missing cache size option is derived from the given ones).
When bdrv_reopen() merges the set of updated options with left out
options that should be kept at their old value, we need to consider this
and filter out any duplicates (which would generally cause errors
because new and old value would contradict each other).
This patch adds a .bdrv_join_options callback to BlockDriver and
implements it for qcow2.
