2021-10-29qapi: Extend -compat to set policy for unstable interfacesMarkus Armbruster
New option parameters unstable-input and unstable-output set policy for unstable interfaces just like deprecated-input and deprecated-output set policy for deprecated interfaces (see commit 6dd75472d5 "qemu-options: New -compat to set policy for deprecated interfaces"). This is intended for testing users of the management interfaces. It is experimental. For now, this covers only syntactic aspects of QMP, i.e. stuff tagged with feature 'unstable'. We may want to extend it to cover semantic aspects, or the command line. Note that there is no good way for management application to detect presence of these new option parameters: they are not visible output of query-qmp-schema or query-command-line-options. Tolerable, because it's meant for testing. If running with -compat fails, skip the test.

2021-10-04qemu-options: Add missing "sockets=2, maxcpus=2" to CLI "-smp 2"Yanan Wang
There is one numa config example in qemu-options.hx currently using "-smp 2" and assuming that there will be 2 sockets and 2 cpus totally. However now the actual calculation logic of missing sockets and cores is not immutable and is considered liable to change. Although we will get maxcpus=2 finally based on current parser, it's always stable to specify it explicitly. So "-smp 2,sockets=2,maxcpus=2" will be optimal when we expect multiple sockets and 2 cpus totally.

2021-10-01machine: Prefer cores over sockets in smp parsing since 6.2Yanan Wang
In the real SMP hardware topology world, it's much more likely that we have high cores-per-socket counts and few sockets totally. While the current preference of sockets over cores in smp parsing results in a virtual cpu topology with low cores-per-sockets counts and a large number of sockets, which is just contrary to the real world. Given that it is better to make the virtual cpu topology be more reflective of the real world and also for the sake of compatibility, we start to prefer cores over sockets over threads in smp parsing since machine type 6.2 for different arches. In this patch, a boolean "smp_prefer_sockets" is added, and we only enable the old preference on older machines and enable the new one since type 6.2 for all arches by using the machine compat mechanism.

2021-10-01machine: Set the value of cpus to match maxcpus if it's omittedYanan Wang
Currently we directly calculate the omitted cpus based on the given incomplete collection of parameters. This makes some cmdlines like: -smp maxcpus=16 -smp sockets=2,maxcpus=16 -smp sockets=2,dies=2,maxcpus=16 -smp sockets=2,cores=4,maxcpus=16 not work. We should probably set the value of cpus to match maxcpus if it's omitted, which will make above configs start to work. So the calculation logic of cpus/maxcpus after this patch will be: When both maxcpus and cpus are omitted, maxcpus will be calculated from the given parameters and cpus will be set equal to maxcpus. When only one of maxcpus and cpus is given then the omitted one will be set to its counterpart's value. Both maxcpus and cpus may be specified, but maxcpus must be equal to or greater than cpus. Note: change in this patch won't affect any existing working cmdlines but allows more incomplete configs to be valid.

2021-10-01machine: Deprecate "parameter=0" SMP configurationsYanan Wang
In the SMP configuration, we should either provide a topology parameter with a reasonable value (greater than zero) or just omit it and QEMU will compute the missing value. The users shouldn't provide a configuration with any parameter of it specified as zero (e.g. -smp 8,sockets=0) which could possibly cause unexpected results in the -smp parsing. So we deprecate this kind of configurations since 6.2 by adding the explicit sanity check.

2021-09-30vl: Add sgx compound properties to expose SGX EPC sections to guestSean Christopherson
Because SGX EPC is enumerated through CPUID, EPC "devices" need to be realized prior to realizing the vCPUs themselves, i.e. long before generic devices are parsed and realized. From a virtualization perspective, the CPUID aspect also means that EPC sections cannot be hotplugged without paravirtualizing the guest kernel (hardware does not support hotplugging as EPC sections must be locked down during pre-boot to provide EPC's security properties). So even though EPC sections could be realized through the generic -devices command, they need to be created much earlier for them to actually be usable by the guest. Place all EPC sections in a contiguous block, somewhat arbitrarily starting after RAM above 4g. Ensuring EPC is in a contiguous region simplifies calculations, e.g. device memory base, PCI hole, etc..., allows dynamic calculation of the total EPC size, e.g. exposing EPC to guests does not require -maxmem, and last but not least allows all of EPC to be enumerated in a single ACPI entry, which is expected by some kernels, e.g. Windows 7 and 8. The new compound properties command for sgx like below: ...... -object memory-backend-epc,id=mem1,size=28M,prealloc=on \ -object memory-backend-epc,id=mem2,size=10M \ -M sgx-epc.0.memdev=mem1,sgx-epc.1.memdev=mem2 Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Yang Zhong <yang.zhong@intel.com> Message-Id: <20210719112136.57018-6-yang.zhong@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-09-06softmmu/vl: Deprecate the old grab optionsThomas Huth
The alt_grab and ctrl_grab parameter of the -display sdl option prevent the QAPIfication of the "sdl" part of the -display option, so we should eventually remove them. And since this feature is also rather niche anyway, we should not clutter the top-level option list with these, so let's also deprecate the "-alt-grab" and the "-ctrl-grab" options while we're at it. Once the deprecation period of "alt_grab" and "ctrl_grab" is over, we then can finally switch the -display sdl option to use QAPI internally, too.

2021-09-06softmmu/vl: Add a "grab-mod" parameter to the -display sdl optionThomas Huth
The -display sdl option is not using QAPI internally yet, and uses hand- crafted parsing instead (see parse_display() in vl.c), which is quite ugly, since most of the other code is using the QAPIfied DisplayOption already. Unfortunately, the "alt_grab" and "ctrl_grab" use underscores in their names which has recently been forbidden in new QAPI code, so a straight conversion is not possible. While we could add some exceptions to the QAPI schema parser for this, the way these parameters have been designed was maybe a bad idea anyway: First, it's not possible to enable both parameters at the same time, thus instead of two boolean parameters it would be better to have only one multi-choice parameter instead. Second, the naming is also somewhat unfortunate since the "alt_grab" parameter is not about the ALT key, but rather about the left SHIFT key that has to be used additionally when the parameter is enabled. So instead of trying to QAPIfy "alt_grab" and "ctrl_grab", let's rather introduce an alternative to these parameters instead, a new parameter called "grab-mod" which can either be set to "lshift-lctrl-lalt" or to "rctrl". In case we ever want to support additional modes later, we can then also simply extend the list of supported strings here.

2021-09-02plugins: allow plugin arguments to be passed directlyMahmoud Mandour
Passing arguments to plugins had to be done through "arg=<argname>". This is redundant and introduces confusion especially when the argument has a name and value (e.g. `-plugin plugin_name,arg="argname=argvalue"`). This allows passing plugin arguments directly e.g: `-plugin plugin_name,argname=argvalue` For now, passing arguments through "arg=" is still supports but outputs a deprecation warning. Also, this commit makes boolean arguments passed to plugins in the `argname=on|off` form instead of the deprecated short-boolean form.

2021-07-21iothread: add aio-max-batch parameterStefano Garzarella
The `aio-max-batch` parameter will be propagated to AIO engines and it will be used to control the maximum number of queued requests. When there are in queue a number of requests equal to `aio-max-batch`, the engine invokes the system call to forward the requests to the kernel. This parameter allows us to control the maximum batch size to reduce the latency that requests might accumulate while queued in the AIO engine queue. If `aio-max-batch` is equal to 0 (default value), the AIO engine will use its default maximum batch size value.

2021-07-14qemu-options: rewrite help for -smp optionsDaniel P. Berrangé
The -smp option help is peculiarly specific about mentioning the CPU upper limits, but these are wrong. The "PC" target has varying max CPU counts depending on the machine type picked. Notes about guest OS limits are inappropriate for QEMU docs. There are way too many machine types for it to be practical to mention actual limits, and some limits are even modified by downstream distribtions. Thus it is better to remove the specific limits entirely. The CPU topology reporting is also not neccessarily specific to the PC platform and descriptions around the rules of usage are somewhat terse. Expand this information with some examples to show effects of defaulting. Reviewed-by: Pankaj Gupta <pankaj.gupta@ionos.com> Reviewed-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Daniel P.

2021-05-14hw/smbios: support for type 41 (onboard devices extended information)Vincent Bernat
Type 41 defines the attributes of devices that are onboard. The original intent was to imply the BIOS had some level of control over the enablement of the associated devices. If network devices are present in this table, by default, udev will name the corresponding interfaces enoX, X being the instance number. Without such information, udev will fallback to using the PCI ID and this usually gives ens3 or ens4. This can be a bit annoying as the name of the network card may depend on the order of options and may change if a new PCI device is added earlier on the commande line. Being able to provide SMBIOS type 41 entry ensure the name of the interface won't change and helps the user guess the right name without booting a first time. This can be invoked with: $QEMU -netdev user,id=internet -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \ -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev The PCI segment is assumed to be 0. This should hold true for most cases. $ dmidecode -t 41 # dmidecode 3.3 Getting SMBIOS data from sysfs. SMBIOS 2.8 present.

Policy "crash" calls abort() when deprecated input is received. Bugs in integration tests may mask the error from policy "reject". Provide a larger hammer: crash outright. Masking that seems unlikely. Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20210318155519.1224118-12-armbru@redhat.com>
2021-03-19qemu-options: New -compat to set policy for deprecated interfacesMarkus Armbruster
New option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<input-policy> configures what to do when deprecated input is received. Input policy can be "accept" (accept silently), or "reject" (reject the request with an error). -compat deprecated-output=<out-policy> configures what to do when deprecated output is sent. Output policy can be "accept" (pass on unchanged), or "hide" (filter out the deprecated parts). Default is "accept". Policies other than "accept" are implemented later in this series. For now, -compat covers only syntactic aspects of QMP, i.e. stuff tagged with feature 'deprecated'. We may want to extend it to cover semantic aspects, CLI, and experimental features. Note that there is no good way for management application to detect presence of -compat: it's not visible output of query-qmp-schema or query-command-line-options. Tolerable, because it's meant for testing. If running with -compat fails, skip the test.

2021-03-15ui: introduce "password-secret" option for SPICE serverDaniel P. Berrangé
Currently when using SPICE the "password" option provides the password in plain text on the command line. This is insecure as it is visible to all processes on the host. As an alternative, the password can be provided separately via the monitor. This introduces a "password-secret" option which lets the password be provided up front. $QEMU --object secret,id=vncsec0,file=passwd.txt \ --spice port=5901,password-secret=vncsec0 Signed-off-by: Daniel P.

2021-03-06chardev: add nodelay optionPaolo Bonzini
The "delay" option was introduced as a way to enable Nagle's algorithm with ",nodelay". Since the short form for boolean options has now been deprecated, introduce a more properly named "nodelay" option. The "delay" option remains as an undocumented option. "delay" and "nodelay" are mutually exclusive. Because the check is done at consumption time, the code also rejects them if one of the two is specified via -set.

Add documentation for '-machine memory-backend' CLI option and how to use it. And document that x-use-canonical-path-for-ramblock-id, is considered to be stable to make sure it won't go away by accident. x- was intended for unstable/iternal properties, and not supposed to be stable option. However it's too late to rename (drop x-) it as it would mean that users will have to mantain both x-use-canonical-path-for-ramblock-id (for QEMU 5.0-5.2) versions and prefix-less for later versions.
