The qemu-img documentation is currently in qemu-nbd.texi in Texinfo format, which we present to the user as: * a qemu-img 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-img manpage * part of the interop/ Sphinx manual The qemu-img rST document uses the new hxtool extension to handle pulling rST fragments out of qemu-img-cmds.hx. The documentation of the various options and commands is rather muddled, with some options being described inside the relevant command description and some in a more general section near the start of the manual. All the command synopses are replicated in the .hx file and then again in the manual. A lot of text is also duplicated in the qemu-img.c code for the help text. I have not attempted to deal with any of this, but have simply transposed the existing structure into rST. As usual, there are some minor formatting changes but no textual changes, except that as with one or two other conversions I have dropped the 'see also' section since it's not very informative and looks odd in the HTML.

2020-02-03docs/sphinx: Add new hxtool Sphinx extensionPeter Maydell
Some of our documentation includes sections which are created by assembling fragments of texinfo from a .hx source file into a .texi file, which is then included from qemu-doc.texi or qemu-img.texi. For Sphinx, rather than creating a file to include, the most natural way to handle this is to have a small custom Sphinx extension which reads the .hx file and process it. So instead of: * makefile produces foo.texi from foo.hx * qemu-doc.texi says '@include foo.texi' we have: * qemu-doc.rst says 'hxtool-doc:: foo.hx' * the Sphinx extension for hxtool has code that runs to handle that Sphinx directive which reads the .hx file and emits the appropriate documentation contents This is pretty much the same way the kerneldoc extension works right now. It also has the advantage that it should work for third-party services like readthedocs that expect to build the docs directly with sphinx rather than by invoking our makefiles. In this commit we implement the hxtool extension. Note that syntax errors in the rST fragments will be correctly reported to the user with the filename and line number within the hx file.

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.

The qemu-nbd documentation is currently in qemu-nbd.texi in Texinfo format, which we present to the user as: * a qemu-nbd 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-nbd manpage * part of the interop/ Sphinx manual This follows the same pattern as commit 27a296fce982 did for the qemu-ga manpage. All the content of the old manpage is retained, except that I have dropped the "This is free software; see the source for copying conditions. There is NO warranty..." text that was in the old AUTHOR section; Sphinx's manpage builder doesn't expect that much text in the AUTHOR section, and since none of our other manpages have it it seems easiest to delete it rather than try to figure out where else in the manpage to put it. The only other textual change is that I have had to give the --nocache option its own description ("Equivalent to --cache=none") because Sphinx doesn't have an equivalent of using item/itemx to share a description between two options. Some minor aspects of the formatting have changed, to suit what is easiest for Sphinx to output. (The most notable is that Sphinx option section option syntax doesn't support '--option foo=bar' with bar underlined rather than bold, so we have to switch to '--option foo=BAR' instead.) The contents of qemu-option-trace.texi are now duplicated in docs/interop/qemu-option-trace.rst.inc, until such time as we complete the conversion of the other files which use it; since it has had only 3 changes in 3 years, this shouldn't be too awkward a burden. (We use .rst.inc because if this file fragment has a .rst extension then Sphinx complains about not seeing it in a toctree.)

2020-01-22acpi: cpuhp: add CPHP_GET_CPU_ID_CMD commandIgor Mammedov
Firmware can enumerate present at boot APs by broadcasting wakeup IPI, so that woken up secondary CPUs could register them-selves. However in CPU hotplug case, it would need to know architecture specific CPU IDs for possible and hotplugged CPUs so it could prepare environment for and wake hotplugged AP. Reuse and extend existing CPU hotplug interface to return architecture specific ID for currently selected CPU in 2 registers: - lower 32 bits in ACPI_CPU_CMD_DATA_OFFSET_RW - upper 32 bits in ACPI_CPU_CMD_DATA2_OFFSET_R On x86, firmware will use CPHP_GET_CPU_ID_CMD for fetching the APIC ID when handling hotplug SMI. Later, CPHP_GET_CPU_ID_CMD will be used on ARM to retrieve MPIDR, which serves the similar to APIC ID purpose.

2020-01-12docs: build an index page for the HTML docsStefan Hajnoczi
There is no index.html start page for the QEMU HTML documentation. An index page is needed so that documentation can be browsed easily on the web. This patch adds an index.html.in template file where the QEMU version number is expanded. It is written in HTML instead of using the existing sphinx (rST) and texi documentation generators because they are heavyweight and would make this harder.
