2024-07-11target/arm: Make vfp_set_fpscr() call vfp_set_{fpcr, fpsr}Peter Maydell
Make vfp_set_fpscr() call vfp_set_fpsr() and vfp_set_fpcr() instead of the other way around. The masking we do when getting and setting vfp.xregs[ARM_VFP_FPSCR] is a little awkward, but we are going to change where we store the underlying FPSR and FPCR information in a later commit, so it will go away then.

2024-07-11target/arm: Make vfp_get_fpscr() call vfp_get_{fpcr, fpsr}Peter Maydell
In AArch32, the floating point control and status bits are all in a single register, FPSCR. In AArch64, these were split into separate FPCR and FPSR registers, but the bit layouts remained the same, with no overlaps, so that you could construct an FPSCR value by ORing FPCR and FPSR, or equivalently could produce FPSR and FPCR by masking an FPSCR value. For QEMU's implementation, we opted to use masking to produce FPSR and FPCR, because we started with an AArch32 implementation of FPSCR. The addition of the (AArch64-only) FEAT_AFP adds new bits to the FPCR which overlap with some bits in the FPSR. This means we'll no longer be able to consider the FPSCR-encoded value as the primary one, but instead need to treat FPSR/FPCR as the primary encoding and construct the FPSCR from those. (This remains possible because the FEAT_AFP bits in FPCR don't appear in the FPSCR.) As the first step in this refactoring, make vfp_get_fpscr() call vfp_get_fpcr() and vfp_get_fpsr(), instead of the other way around. Note that vfp_get_fpcsr_from_host() returns only bits in the FPSR (for the cumulative fp exception bits), so we can simply rename it without needing to add a new function for getting FPCR bits.

2024-07-11Consider discard option when writing zerosNir Soffer
When opening an image with discard=off, we punch hole in the image when writing zeroes, making the image sparse. This breaks users that want to ensure that writes cannot fail with ENOSPACE by using fully allocated images[1]. bdrv_co_pwrite_zeroes() correctly disables BDRV_REQ_MAY_UNMAP if we opened the child without discard=unmap or discard=on. But we don't go through this function when accessing the top node. Move the check down to bdrv_co_do_pwrite_zeroes() which seems to be used in all code paths. This change implements the documented behavior, punching holes only when opening the image with discard=on or discard=unmap. This may not be the best default but can improve it later. The test depends on a file system supporting discard, deallocating the entire file when punching hole with the length of the entire file. Tested with xfs, ext4, and tmpfs.

2024-07-10virtio-mem: improve error message when unplug of device fails due to plugged ↵David Hildenbrand
memory The error message is actually expressive, considering QEMU only. But when called from Libvirt, talking about "size" can be confusing, because in Libvirt "size" translates to the memory backend size in QEMU (maximum size) and "current" translates to the QEMU "size" property. Let's simply avoid talking about the "size" property and spell out that some device memory is still plugged.

2024-07-06sphinx/qapidoc: Fix to generate doc for explicit, unboxed argumentsMarkus Armbruster
When a command's arguments are specified as an explicit type T, generated documentation points to the members of T. Example: ## # @announce-self: # # Trigger generation of broadcast RARP frames to update network [...] ## { 'command': 'announce-self', 'boxed': true, 'data' : 'AnnounceParameters'} generates "announce-self" (Command) ------------------------- Trigger generation of broadcast RARP frames to update network [...] Arguments ~~~~~~~~~ The members of "AnnounceParameters" Except when the command takes its arguments unboxed , i.e. it doesn't have 'boxed': true, we generate *nothing*. A few commands have a reference in their doc comment to compensate, but most don't. Example: ## # @blockdev-snapshot-sync: # # Takes a synchronous snapshot of a block device. # # For the arguments, see the documentation of BlockdevSnapshotSync. [...] ## { 'command': 'blockdev-snapshot-sync', 'data': 'BlockdevSnapshotSync', 'allow-preconfig': true } generates "blockdev-snapshot-sync" (Command) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Takes a synchronous snapshot of a block device. For the arguments, see the documentation of BlockdevSnapshotSync. [...] Same for event data. Fix qapidoc.py to generate the reference regardless of boxing. Delete now redundant references in the doc comments.

2024-07-06qapi/parser: don't parse rST markup as section headersJohn Snow
The double-colon synax is rST formatting that precedes a literal code block. We do not want to capture these as QAPI-specific sections. Coerce blocks that start with e.g. "Example::" to be parsed as untagged paragraphs instead of special tagged sections.

Generally, surround command-line options with ``literal`` markup to help it stand out from prose in rendered HTML, and add cross-references to replace "see also" messages.

2024-07-06qapi: convert "Note" sections to plain rSTJohn Snow
We do not need a dedicated section for notes. By eliminating a specially parsed section, these notes can be treated as normal rST paragraphs in the new QMP reference manual, and can be placed and styled much more flexibly. Convert all existing "Note" and "Notes" sections to pure rST. As part of the conversion, capitalize the first letter of each sentence and add trailing punctuation where appropriate to ensure notes look sensible and consistent in rendered HTML documentation. Markup is also re-aligned to the de-facto standard of 3 spaces for directives. Update docs/devel/qapi-code-gen.rst to reflect the new paradigm, and update the QAPI parser to prohibit "Note" sections while suggesting a new syntax. The exact formatting to use is a matter of taste, but a good candidate is simply: .. note:: lorem ipsum ... ... dolor sit amet ... ... consectetur adipiscing elit ... ... but there are other choices, too. The Sphinx readthedocs theme offers theming for the following forms (capitalization unimportant); all are adorned with a (!) symbol () in the title bar for rendered HTML docs. See https://sphinx-rtd-theme.readthedocs.io/en/stable/demo/demo.html#admonitions for examples of each directive/admonition in use. These are rendered in orange: .. Attention:: ... .. Caution:: ... .. WARNING:: ... These are rendered in red: .. DANGER:: ... .. Error:: ... These are rendered in green: .. Hint:: ... .. Important:: ... .. Tip:: ... These are rendered in blue: .. Note:: ... .. admonition:: custom title admonition body text This patch uses ".. note::" almost everywhere, with just two "caution" directives. Several instances of "Notes:" have been converted to merely ".. note::", or multiple ".. note::" where appropriate. ".. admonition:: notes" is used in a few places where we had an ordered list of multiple notes that would not make sense as standalone/separate admonitions. Two "Note:" following "Example:" have been turned into ordinary paragraphs within the example. NOTE: Because qapidoc.py does not attempt to preserve source ordering of sections, the conversion of Notes from a "tagged section" to an "untagged section" means that rendering order for some notes *may change* as a result of this patch. The forthcoming qapidoc.py rewrite strictly preserves source ordering in the rendered documentation, so this issue will be rectified in the new generator.

2024-07-06qapi: nail down convention that Errors sections are listsJohn Snow

2024-07-06qapi: fix non-compliant JSON examplesJohn Snow
The new QMP documentation generator wants to parse all examples as "QMP". We have an existing QMP lexer in docs/sphinx/qmp_lexer.py (Seen in-use here: https://qemu-project.gitlab.io/qemu/interop/bitmaps.html) that allows the use of "->", "<-" and "..." tokens to denote QMP protocol flow with elisions, but otherwise defers to the JSON lexer. To utilize this lexer for the existing QAPI documentation, we need them to conform to a standard so that they lex and render correctly. Once the QMP lexer is active for examples, errant QMP/JSON will produce warning messages and fail the build. Fix any invalid JSON found in QAPI documentation (identified by attempting to lex all examples as QMP; see subsequent commits). Additionally, elisions must be standardized for the QMP lexer; they must be represented as the value "...", so three examples have been adjusted to support that format here.

2024-07-06docs/qapidoc: fix nested parsing under untagged sectionsJohn Snow
Sphinx does not like sections without titles, because it wants to convert every section into a reference. When there is no title, it struggles to do this and transforms the tree inproperly. Depending on the rST used, this may result in an assertion error deep in the docutils HTMLWriter. (Observed when using ".. admonition:: Notes" under such a section - When this is transformed with its own <title> element, Sphinx is fooled into believing this title belongs to the section and incorrect mutates the docutils tree, leading to errors during rendering time.) When parsing an untagged section (free paragraphs), skip making a hollow section and instead append the parse results to the prior section. Many Bothans died to bring us this information. The resulting output changes are basically invisible.

2024-07-06qapi/parser: fix comment parsing immediately following a doc blockJohn Snow
If a comment immediately follows a doc block, the parser doesn't ignore that token appropriately. Fix that. e.g. > ## > # = Hello World! > ## > > # I'm a comment! will break the parser, because it does not properly ignore the comment token if it immediately follows a doc block.

2024-07-06qapi/parser: preserve indentation in QAPIDoc sectionsJohn Snow
Change get_doc_indented() to preserve indentation on all subsequent text lines, and create a compatibility dedent() function for qapidoc.py that removes indentation the same way get_doc_indented() did. This is being done for the benefit of a new qapidoc generator which requires that indentation in argument and features sections are preserved. Prior to this patch, a section like this: ``` @name: lorem ipsum dolor sit amet consectetur adipiscing elit ``` would have its body text be parsed into: ``` lorem ipsum dolor sit amet consectetur adipiscing elit ``` We want to preserve the indentation for even the first body line so that the entire block can be parsed directly as rST. This patch would now parse that segment into: ``` lorem ipsum dolor sit amet consectetur adipiscing elit ``` This is helpful for formatting arguments and features as field lists in rST, where the new generator will format this information as: ``` :arg type name: lorem ipsum dolor sit amet consectetur apidiscing elit ``` ...and can be formed by the simple concatenation of the field list construct and the body text. The indents help preserve the continuation of a block-level element, and further allow the use of additional rST block-level constructs such as code blocks, lists, and other such markup. This understandably breaks the existing qapidoc.py; so a new function is added there to dedent the text for compatibility. Once the new generator is merged, this function will not be needed any longer and can be dropped. I verified this patch changes absolutely nothing by comparing the md5sums of the QMP ref html pages both before and after the change, so it's certified inert. QAPI test output has been updated to reflect the new strategy of preserving indents for rST.

2024-07-06docs/qapidoc: delint a tiny portion of the moduleJohn Snow
In a forthcoming series that adds a new QMP documentation generator, it will be helpful to have a linting baseline. However, there's no need to shuffle around the deck chairs too much, because most of this code will be removed once that new qapidoc generator (the "transmogrifier") is in place. To ease my pain: just turn off the black auto-formatter for most, but not all, of qapidoc.py. This will help ensure that *new* code follows a coding standard without bothering too much with cleaning up the existing code. Code that I intend to keep is still subject to the delinting beam.
