[Qemu-devel] [PATCH 1/2] qemu-doc: Move appendix "Deprecated features" to its own file

[Markus Armbruster]

Consumers of QEMU need to track feature deprecation.  Keeping
deprecation documentation in its own file helps in two small ways:

* You can track changes the easy and obvious way, with git-log.
  Before, you had to resort to more complex gittery like "git-log
  --oneline -L '/@node Deprecated features/,/@node Supported build
  platforms/:qemu-doc.texi'"

* It lets us use MAINTAINERS to copy interested parties on deprecation
  patches, so they can advise or object before they're a done deal.
  The next commit will do that for libvirt.

+@node Deprecated features
+@appendix Deprecated features
+
+In general features are intended to be supported indefinitely once
+introduced into QEMU. In the event that a feature needs to be removed,
+it will be listed in this appendix. The feature will remain functional
+for 2 releases prior to actual removal. Deprecated features may also
+generate warnings on the console when QEMU starts up, or if activated
+via a monitor command, however, this is not a mandatory requirement.
+
+Prior to the 2.10.0 release there was no official policy on how
+long features would be deprecated prior to their removal, nor
+any documented list of which features were deprecated. Thus
+any features deprecated prior to 2.10.0 will be treated as if
+they were first deprecated in the 2.10.0 release.
+
+What follows is a list of all features currently marked as
+deprecated.
+
+@section Build options
+
+@subsection GTK 2.x
+
+Previously QEMU has supported building against both GTK 2.x
+and 3.x series APIs. Support for the GTK 2.x builds will be
+discontinued, so maintainers should switch to using GTK 3.x,
+which is the default.
+
+@subsection SDL 1.2
+
+Previously QEMU has supported building against both SDL 1.2
+and 2.0 series APIs. Support for the SDL 1.2 builds will be
+discontinued, so maintainers should switch to using SDL 2.0,
+which is the default.
+
+@section System emulator command line arguments
+
+@subsection -no-kvm (since 1.3.0)
+
+The ``-no-kvm'' argument is now a synonym for setting
+``-machine accel=tcg''.
+
+@subsection -vnc tls (since 2.5.0)
+
+The ``-vnc tls'' argument is now a synonym for setting
+``-object tls-creds-anon,id=tls0'' combined with
+``-vnc tls-creds=tls0'
+
+@subsection -vnc x509 (since 2.5.0)
+
+The ``-vnc x509=/path/to/certs'' argument is now a
+synonym for setting
+``-object tls-creds-x509,dir=/path/to/certs,id=tls0,verify-peer=no''
+combined with ``-vnc tls-creds=tls0'
+
+@subsection -vnc x509verify (since 2.5.0)
+
+The ``-vnc x509verify=/path/to/certs'' argument is now a
+synonym for setting
+``-object tls-creds-x509,dir=/path/to/certs,id=tls0,verify-peer=yes''
+combined with ``-vnc tls-creds=tls0'
+
+@subsection -tftp (since 2.6.0)
+
+The ``-tftp /some/dir'' argument is replaced by either
+``-netdev user,id=x,tftp=/some/dir '' (for pluggable NICs, accompanied
+with ``-device ...,netdev=x''), or ``-nic user,tftp=/some/dir''
+(for embedded NICs). The new syntax allows different settings to be
+provided per NIC.
+
+@subsection -bootp (since 2.6.0)
+
+The ``-bootp /some/file'' argument is replaced by either
+``-netdev user,id=x,bootp=/some/file '' (for pluggable NICs, accompanied
+with ``-device ...,netdev=x''), or ``-nic user,bootp=/some/file''
+(for embedded NICs). The new syntax allows different settings to be
+provided per NIC.
+
+@subsection -redir (since 2.6.0)
+
+The ``-redir [tcp|udp]:hostport:[guestaddr]:guestport'' argument is
+replaced by either
+``-netdev user,id=x,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport''
+(for pluggable NICs, accompanied with ``-device ...,netdev=x'') or
+``-nic user,hostfwd=[tcp|udp]:[hostaddr]:hostport-[guestaddr]:guestport''
+(for embedded NICs). The new syntax allows different settings to be
+provided per NIC.
+
+@subsection -smb (since 2.6.0)
+
+The ``-smb /some/dir'' argument is replaced by either
+``-netdev user,id=x,smb=/some/dir '' (for pluggable NICs, accompanied
+with ``-device ...,netdev=x''), or ``-nic user,smb=/some/dir''
+(for embedded NICs). The new syntax allows different settings to be
+provided per NIC.
+
+@subsection -drive cyls=...,heads=...,secs=...,trans=... (since 2.10.0)
+
+The drive geometry arguments are replaced by the the geometry arguments
+that can be specified with the ``-device'' parameter.
+
+@subsection -drive serial=... (since 2.10.0)
+
+The drive serial argument is replaced by the the serial argument
+that can be specified with the ``-device'' parameter.
+
+@subsection -drive addr=... (since 2.10.0)
+
+The drive addr argument is replaced by the the addr argument
+that can be specified with the ``-device'' parameter.
+
+@subsection -usbdevice (since 2.10.0)
+
+The ``-usbdevice DEV'' argument is now a synonym for setting
+the ``-device usb-DEV'' argument instead. The deprecated syntax
+would automatically enable USB support on the machine type.
+If using the new syntax, USB support must be explicitly
+enabled via the ``-machine usb=on'' argument.
+
+@subsection -nodefconfig (since 2.11.0)
+
+The ``-nodefconfig`` argument is a synonym for ``-no-user-config``.
+
+@subsection -balloon (since 2.12.0)
+
+The @option{--balloon virtio} argument has been superseded by
+@option{--device virtio-balloon}.
+
+@subsection -machine s390-squash-mcss=on|off (since 2.12.0)
+
+The ``s390-squash-mcss=on`` property has been obsoleted by allowing the
+cssid to be chosen freely. Instead of squashing subchannels into the
+default channel subsystem image for guests that do not support multiple
+channel subsystems, all devices can be put into the default channel
+subsystem image.
+
+@subsection -fsdev handle (since 2.12.0)
+
+The ``handle'' fsdev backend does not support symlinks and causes the 9p
+filesystem in the guest to fail a fair amount of tests from the PJD POSIX
+filesystem test suite. Also it requires the CAP_DAC_READ_SEARCH capability,
+which is not the recommended way to run QEMU. This backend should not be
+used and it will be removed with no replacement.
+
+@subsection -no-frame (since 2.12.0)
+
+The @code{--no-frame} argument works with SDL 1.2 only. The other user
+interfaces never implemented this in the first place. So this will be
+removed together with SDL 1.2 support.
+
+@subsection -rtc-td-hack (since 2.12.0)
+
+The @code{-rtc-td-hack} option has been replaced by
+@code{-rtc driftfix=slew}.
+
+@subsection -localtime (since 2.12.0)
+
+The @code{-localtime} option has been replaced by @code{-rtc base=localtime}.
+
+@subsection -startdate (since 2.12.0)
+
+The @code{-startdate} option has been replaced by @code{-rtc base=@var{date}}.
+
+@subsection -virtioconsole (since 3.0.0)
+
+Option @option{-virtioconsole} has been replaced by
+@option{-device virtconsole}.
+
+@subsection -clock (since 3.0.0)
+
+The @code{-clock} option is ignored since QEMU version 1.7.0. There is no
+replacement since it is not needed anymore.
+
+@subsection -enable-hax (since 3.0.0)
+
+The @option{-enable-hax} option has been replaced by @option{-accel hax}.
+Both options have been introduced in QEMU version 2.9.0.
+
+@subsection -drive file=json:@{...@{'driver':'file'@}@} (since 3.0)
+
+The 'file' driver for drives is no longer appropriate for character or host
+devices and will only accept regular files (S_IFREG). The correct driver
+for these file types is 'host_cdrom' or 'host_device' as appropriate.
+
+@section QEMU Machine Protocol (QMP) commands
+
+@subsection block-dirty-bitmap-add "autoload" parameter (since 2.12.0)
+
+"autoload" parameter is now ignored. All bitmaps are automatically loaded
+from qcow2 images.
+
+@subsection query-cpus (since 2.12.0)
+
+The ``query-cpus'' command is replaced by the ``query-cpus-fast'' command.
+
+@subsection query-cpus-fast "arch" output member (since 3.0.0)
+
+The ``arch'' output member of the ``query-cpus-fast'' command is
+replaced by the ``target'' output member.
+
+@section System emulator devices
+
+@subsection ivshmem (since 2.6.0)
+
+The ``ivshmem'' device type is replaced by either the ``ivshmem-plain''
+or ``ivshmem-doorbell`` device types.
+
+@subsection Page size support < 4k for embedded PowerPC CPUs (since 2.12.0)
+
+qemu-system-ppcemb will be removed. qemu-system-ppc (or qemu-system-ppc64)
+should be used instead. That means that embedded 4xx PowerPC CPUs will not
+support page sizes < 4096 any longer.
+
+@section System emulator machines
+
+@subsection pc-0.10 and pc-0.11 (since 3.0)
+
+These machine types are very old and likely can not be used for live migration
+from old QEMU versions anymore. A newer machine type should be used instead.
+
+@section Device options
+
+@subsection Block device options
+
+@subsubsection "backing": "" (since 2.12.0)
+
+In order to prevent QEMU from automatically opening an image's backing
+chain, use ``"backing": null'' instead.
+
+@subsection vio-spapr-device device options
+
+@subsubsection "irq": "" (since 3.0.0)
+
+The ``irq'' property is obsoleted.

Should we have a maintainer for the file, too? (I guess not, because
deprecation patches should go through the specific subsystems...)
And what about a "S:" line?

Anyway:

I don't think adding a maintainer makes sense for this file.

I don't think that makes too much sense, either.

If anything, qemu-deprecated.texi should be in a category 'maintained
by everybody', i.e. qemu-devel. Just like qemu-doc.texi, which does not
have an entry in MAINTAINERS at all.

This MAINTAINERS entry doesn't declare maintainers, only reviewers.

We can change that if a maintainer steps up.

Just like all the other files that lack a maintainer.

Note, that libvir-list requires senders to be subscribed before mails are
delivered, otherwise they go into moderation queue. My normal approach. as
the person moderating, is to whitelist all human senders who get moderated,
so it is only a one-time pain point per person.

Thankyou spammers :-(

Regards,
Daniel

Actually, the list bot is even more stupid than that - a first-time 
poster that subscribes first is STILL moderated (and sometimes you can 
see evidence of that when someone posts 2 or 3 nearly identical messages 
in a short time - first before subscribing, then again after, thinking 
that subscribing will make a difference). Whitelisting happens 
independently from subscription.

But also a hearty thank you to all list moderators that reduce the 
amount of spam actually making it to the list.
