2020-06-26numa: forbid '-numa node, mem' for 5.1 and newer machine typesIgor Mammedov
Deprecation period is run out and it's a time to flip the switch introduced by cd5ff8333a. Disable legacy option for new machine types (since 5.1) and amend documentation. '-numa node,memdev' shall be used instead of disabled option with new machine types.

2020-05-14qemu-options.hx: 9p: clarify -virtfs vs. -fsdevChristian Schoenebeck
The docs are ambiguous about the difference (or actually their equality) between options '-virtfs' vs. '-fsdev'. So clarify that '-virtfs' is actually just a convenience shortcut for its generalized form '-fsdev' in conjunction with '-device virtio-9p-pci'. And as we're at it, also be a bit more descriptive what 9pfs is actually used for.

2020-04-14docs: Improve our gdbstub documentationPeter Maydell
The documentation of our -s and -gdb options is quite old; in particular it still claims that it will cause QEMU to stop and wait for the gdb connection, when this has not been true for some time: you also need to pass -S if you want to make QEMU not launch the guest on startup. Improve the documentation to mention this requirement in the executable's --help output, the documentation of the -gdb option in the manual, and in the "GDB usage" chapter. Includes some minor tweaks to these paragraphs of documentation since I was editing them anyway (such as dropping the description of our gdb support as "primitive").

2020-03-06qemu-options.hx: Fix up the autogenerated rSTPeter Maydell
This commit contains hand-written fixes for some issues with the autogenerated rST fragments in qemu-options.hx: * Sphinx complains about the UTF-8 art table in the documentation of the -drive option. Replace it with a proper rST format table. * rST does not like definition list entries with no actual definition, but it is possible to work around this by putting a single escaped literal space as the definition line. * The "-g widthxheight" option documentation suffers particularly badly from losing the distinction between italics and fixed-width as a result of the auto conversion, so put it back in again. * The script missed some places that use the |qemu_system| etc macros and need to be marked up as parsed-literal blocks. * The script autogenerated an expanded out version of the contents of qemu-option-trace.texi; replace it with an qemu-option-trace.rst.inc include. This is sufficient that we can enable inclusion of the option documentation from invocation.rst.

2020-03-06docs: Roll -prom-env and -g target-specific info into qemu-options.hxPeter Maydell
The SPARC and PPC targets currently have a fragment of target-specific information about the -g and -prom options which would be better placed as part of the general documentation of those options in qemu-options.hx. Move the relevant information to those locations. SPARC also has a bit of text about the -M option which is out of date and provides no useful information over the generic documentation of that option, so just delete it. The motivation here is again to avoid having to awkwardly include this text into the rST version of the qemu.1 manpage.

Currently the per-target documentation for those targets that implement semihosting includes a bit of text that goes into both the manual and the manpage about options specific to the target. This text is redundant with the earlier generic option description of the semihosting option produced from qemu-options.hx. To avoid having to create a lot of stub include files to include into the rST generated qemu.1 manpage, roll target-specific bits of information into the qemu-options.hx text, so the user doesn't have to look in two places for this information.

2020-02-07docs: stop documenting the e1000 NIC model as the defaultDaniel P. Berrangé
The default NIC model for QEMU varies per machine type, and is liable to change across machine type versions. Documenting e1000 NIC as the default for PC/i386 is thus misleading to users at best. In particular the PC q35 machine type switched to use e1000e, but only in machine type versions after 2.11. Rather than try to explain which NIC model is used for each machine type version, remove mention of e1000 as the default, and steer users towards always specifying their desired model.

2020-01-23qemu-block-drivers: Convert to rSTPeter Maydell
The qemu-block-drivers documentation is currently in docs/qemu-block-drivers.texi in Texinfo format, which we present to the user as: * a qemu-block-drivers manpage * a section of the main qemu-doc HTML documentation Convert the documentation to rST format, and present it to the user as: * a qemu-block-drivers manpage * part of the system/ Sphinx manual This follows the same pattern we've done for qemu-ga and qemu-nbd. We have to drop a cross-reference from the documentation of the -cdrom option back to the qemu-block-drivers documentation, since they're no longer within the same texinfo document. As noted in a comment, the manpage output is slightly compromised due to limitations in Sphinx. In an ideal world, the HTML output would have the various headings like 'Disk image file formats' as top-level section headings (which then appear in the overall system manual's table-of-contents), and it would not have the section headings which make sense only for the manpage like 'synopsis', 'description', and 'see also'. Unfortunately, the mechanism Sphinx provides for restricting pieces of documentation is limited to the point of being flawed: the 'only::' directive is implemented as a filter that is applied at a very late stage in the document processing pipeline, rather than as an early equivalent of an #ifdef. This means that Sphinx's process of identifying which section heading markup styles are which levels of heading gets confused if the 'only::' directive contains section headings which would affect the heading-level of a later heading. I have opted to prioritise making the HTML format look better, with the compromise being that in the manpage the 'Disk image file formats' &c headings are top-level headings rather than being sub-headings under the traditional 'Description' top-level section title.

2019-12-17Remove the core bluetooth codeThomas Huth
It's been deprecated since QEMU v3.1. We've explicitly asked in the deprecation message that people should speak up on qemu-devel in case they are still actively using the bluetooth part of QEMU, but nobody ever replied that they are really still using it. I've tried it on my own to use this bluetooth subsystem for one of my guests, but I was also not able to get it running anymore: When I was trying to pass-through a real bluetooth device, either the guest did not see the device at all, or the guest crashed. Even worse for the emulated device: When running qemu-system-x86_64 -bt device:keyboard QEMU crashes once you hit a key. So it seems like the bluetooth stack is not only neglected, it is completely bitrotten, as far as I can tell. The only attention that this code got during the past years were some CVEs that have been spotted there. So this code is a burden for the developers, without any real benefit anymore. Time to remove it. Note: hw/bt/Kconfig only gets cleared but not removed here yet. Otherwise there is a problem with the *-softmmu/config-devices.mak.d dependency files - they still contain a reference to this file which gets evaluated first on some build hosts, before the file gets properly recreated. To avoid breaking these builders, we still need the file around for some time. It will get removed in a couple of weeks instead.

2019-11-05qemu-options: Rework the help text of the '-display' optionThomas Huth
Improve the help text of the "-display" option: - Only print the options that we have enabled in the binary (similar to what we do for other options like -netdev already) - The "frame=on|off" from "-display sdl" has been removed in commit 09bd7ba9f5f7 ("Remove deprecated -no-frame option"), so we should not show this in the help text anymore - The "-display egl-headless" line was missing a "\n" at the end - Indent the default display text in a nicer way Signed-off-by: Thomas Huth <huth@tuxfamily.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-id: 20191023120129.13721-1-huth@tuxfamily.org Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2019-10-18audio: add mixing-engine option (documentation)Kővágó, Zoltán
This will allow us to disable mixeng when we use a decent backend. Disabling mixeng have a few advantages: * we no longer convert the audio output from one format to another, when the underlying audio system would just convert it to a third format. We no longer convert, only the underlying system, when needed. * the underlying system probably has better resampling and sample format converting methods anyway... * we may support formats that the mixeng currently does not support (S24 or float samples, more than two channels) * when using an audio server (like pulseaudio) different sound card outputs will show up as separate streams, even if we use only one backend Disadvantages: * audio capturing no longer works (wavcapture, and vnc audio extension) * some backends only support a single playback stream or very picky about the audio format. In this case we can't disable mixeng. Originally thw two main use cases of the disabled option was: using unsupported audio formats (5.1 and 7.1 audio) and having different pulseaudio streams per audio frontend. Since we can have multiple -audiodevs, the latter is not that important, so currently you only need this option if you want to use 5.1 or 7.1 audio (implemented in a later patch), otherwise it's probably better to stick to the old and tried mixeng, since it's less picky about the backends. The ideal solution would be to port as much as possible to gstreamer, but this is currently out of scope: https://wiki.qemu.org/Internships/ProjectIdeas/AudioGStreamer Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com> Message-id: 5765186a7aadd51a72bc7d3e804307f0ee8a34ce.1570996490.git.DirtY.iCE.hu@gmail.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2019-10-109p: Added virtfs option 'multidevs=remap|forbid|warn'Antonios Motakis
'warn' (default): Only log an error message (once) on host if more than one device is shared by same export, except of that just ignore this config error though. This is the default behaviour for not breaking existing installations implying that they really know what they are doing. 'forbid': Like 'warn', but except of just logging an error this also denies access of guest to additional devices. 'remap': Allows to share more than one device per export by remapping inodes from host to guest appropriately. To support multiple devices on the 9p share, and avoid qid path collisions we take the device id as input to generate a unique QID path. The lowest 48 bits of the path will be set equal to the file inode, and the top bits will be uniquely assigned based on the top 16 bits of the inode and the device id. Signed-off-by: Antonios Motakis <antonios.motakis@huawei.com> [CS: - Rebased to https://github.com/gkurz/qemu/commits/9p-next (SHA1 7fc4c49e91). - Added virtfs option 'multidevs', original patch simply did the inode remapping without being asked. - Updated hash calls to new xxhash API. - Updated docs for new option 'multidevs'. - Fixed v9fs_do_readdir() not having remapped inodes. - Log error message when running out of prefixes in qid_path_prefixmap(). - Fixed definition of QPATH_INO_MASK. - Wrapped qpp_table initialization to dedicated qpp_table_init() function. - Dropped unnecessary parantheses in qpp_lookup_func(). - Dropped unnecessary g_malloc0() result checks. ] Signed-off-by: Christian Schoenebeck <qemu_oss@crudebyte.com> [groug: - Moved "multidevs" parsing to the local backend. - Added hint to invalid multidevs option error. - Turn "remap" into "x-remap". ] Signed-off-by: Greg Kurz <groug@kaod.org>
