2021-07-18docs: Move deprecation, build and license info out of system/Peter Maydell1-339/+0
Now that we have a single Sphinx manual rather than multiple manuals, we can provide a better place for "common to all of QEMU" information like the deprecation notices, build platforms, license information, which we currently have in the system/ manual even though it applies to all of QEMU. Create a new directory about/ on the same level as system/, user/, etc, and move these documents there.

2021-07-09qemu-img: Require -F with -b backing imageEric Blake1-20/+0
Back in commit d9f059aa6c (qemu-img: Deprecate use of -b without -F), we deprecated the ability to create a file with a backing image that requires qemu to perform format probing. Qemu can still probe older files for backwards compatibility, but it is time to finish off the ability to create such images, due to the potential security risk they present. Update a couple of iotests affected by the change.

This was deprecated back in bc5ee6da7 (qcow2: Deprecate use of qemu-img amend to change backing file), and no one in the meantime has given any reasons why it should be supported. Time to make change attempts a hard error (but for convenience, specifying the _same_ backing chain is not forbidden). Update a couple of iotests to match.

2021-07-06Deprecate pmem=on with non-DAX capable backend fileIgor Mammedov1-0/+18
It is not safe to pretend that emulated NVDIMM supports persistence while backend actually failed to enable it and used non-persistent mapping as fall back. Instead of falling-back, QEMU should be more strict and error out with clear message that it's not supported. So if user asks for persistence (pmem=on), they should store backing file on NVDIMM.

2021-07-05ui: Mark the '-no-quit' option as deprecatedThomas Huth1-0/+6
It's just a wrapper around the -display ...,window-close=off parameter, and the name "no-quit" is rather confusing compared to "window-close" (since there are still other means to quit the emulator), so we should rather tell our users to use the "window-close" parameter instead. While we're at it, update the documentation to state that "-no-quit" is available for GTK, too, not only for SDL. Reviewed-by: Daniel P.

2021-07-05ui: Fix the "-display sdl,window_close=..." parameterThomas Huth1-0/+6
According to the QAPI schema, there is a "-" and not a "_" between "window" and "close", and we're also talking about "window-close" in the long parameter description in qemu-options.hx, so we should make sure that we rather use the variant with the "-" by default instead of only allowing the one with the "_" here. The old way still stays enabled for compatibility, but we deprecate it, so that we can switch to a QAPIfied parameter one day more easily.

When trying to remove the -usbdevice option, there were complaints that "-usbdevice braille" is still a very useful shortcut for some people. Thus we never remove this option. Since it's not such a big burden to keep it around, and it's also convenient in the sense that you don't have to worry to enable a host controller explicitly with this option, we should remove it from he deprecation list again. However, there is one exception: "-usbdevice audio" should go away, since audio devices without "audiodev=..." parameter are also on the deprecation list and you cannot use "-usbdevice audio" with "audiodev".

2021-03-08utils: Deprecate hex-with-suffix sizesEric Blake1-0/+8
Supporting '0x20M' looks odd, particularly since we have a 'B' suffix that is ambiguous for bytes, as well as a less-frequently-used 'E' suffix for extremely large exibytes. In practice, people using hex inputs are specifying values in bytes (and would have written 0x2000000, or possibly relied on default_suffix in the case of qemu_strtosz_MiB), and the use of scaling suffixes makes the most sense for inputs in decimal (where the user would write 32M). But rather than outright dropping support for hex-with-suffix, let's follow our deprecation policy. Sadly, since qemu_strtosz() does not have an Err** parameter, and plumbing that in would be a much larger task, we instead go with just directly emitting the deprecation warning to stderr.

2021-03-06qemu-option: do not suggest using the delay optionPaolo Bonzini1-0/+6
The "delay" option was a hack that was introduced to allow writing "nodelay". We are adding a "nodelay" option to be used as "nodelay=on", so recommend it instead of "delay". This is quite ugly, but a proper deprecation of "delay" cannot be done if QEMU starts suggesting it. Since it's the only case I opted for this very much ad-hoc patch. Reviewed-by: Daniel P.

2021-03-06KVM: x86: deprecate -M kernel-irqchip=off except for -M isapcPaolo Bonzini1-0/+7
The userspace local APIC is basically untested and does not support many features such as TSC deadline timer, x2APIC or PV spinlocks. On the other hand, the PIT and IOAPIC are okay as they are not tied to the processor and are tested with -M kernel-irqchip=split. Therefore, deprecate the local APIC and, with it, limit -M kernel-irqchip=off to the ISA PC machine type, which does not have a local APIC at all.

2021-02-25vl: deprecate -writeconfigPaolo Bonzini1-0/+7
The functionality of -writeconfig is limited and the code does not even try to detect cases where it prints incorrect syntax (for example if values have a quote in them, since qemu_config_parse does not support any kind of escaping) so remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-01-29os: deprecate the -enable-fips option and QEMU's FIPS enforcementDaniel P. Berrangé1-0/+12
The -enable-fips option was added a long time ago to prevent the use of single DES when VNC when FIPS mode is enabled. It should never have been added, because apps are supposed to unconditionally honour FIPS mode based on the '/proc/sys/crypto/fips_enabled' file contents. In addition there is more to achieving FIPS compliance than merely blocking use of certain algorithms. Those algorithms which are used need to perform self-tests at runtime. QEMU's built-in cryptography provider has no support for self-tests, and neither does the nettle library. If QEMU is required to be used in a FIPS enabled host, then it must be built with the libgcrypt library enabled, which will unconditionally enforce FIPS compliance in any algorithm usage. Thus there is no need to keep either the -enable-fips option in QEMU, or QEMU's internal FIPS checking methods.

2021-01-23qemu-option: warn for short-form boolean optionsPaolo Bonzini1-0/+6
Options such as "server" or "nowait", that are commonly found in -chardev, are sugar for "server=on" and "wait=off". This is quite surprising and also does not have any notion of typing attached. It is even possible to do "-device e1000,noid" and get a device with "id=off". Deprecate it and print a warning when it is encountered. In general, this short form for boolean options only seems to be in wide use for -chardev and -spice. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
