2024-07-09virtio-iommu: Revert transient enablement of IOMMU MR in bypass modeEric Auger1-12/+0
In 94df5b2180d6 ("virtio-iommu: Fix 64kB host page size VFIO device assignment"), in case of bypass mode, we transiently enabled the IOMMU MR to allow the set_page_size_mask() to be called and pass information about the page size mask constraint of cold plugged VFIO devices. Now we do not use the IOMMU MR callback anymore, we can just get rid of this hack.

2024-07-09memory: remove IOMMU MR iommu_set_page_size_mask() callbackEric Auger5-105/+0
Everything is now in place to use the Host IOMMU Device callbacks to retrieve the page size mask usable with a given assigned device. This new method brings the advantage to pass the info much earlier to the virtual IOMMU and before the IOMMU MR gets enabled. So let's remove the call to memory_region_iommu_set_page_size_mask in vfio common.c and remove the single implementation of the IOMMU MR callback in the virtio-iommu.c Signed-off-by: Eric Auger <eric.auger@redhat.com> Reviewed-by: Cédric Le Goater <clg@redhat.com> Reviewed-by: Zhenzhong Duan <zhenzhong.duan@intel.com> Reviewed-by: Michael S.

Retrieve the Host IOMMU Device page size mask when this latter is set. This allows to get the information much sooner than when relying on IOMMU MR set_page_size_mask() call, whcih happens when the IOMMU MR gets enabled. We introduce check_page_size_mask() helper whose code is inherited from current virtio_iommu_set_page_size_mask() implementation. This callback will be removed in a subsequent patch.

2024-07-06sphinx/qapidoc: Fix to generate doc for explicit, unboxed argumentsMarkus Armbruster2-14/+5
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.

2024-07-06qapi: convert "Note" sections to plain rSTJohn Snow30-253/+261
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: fix non-compliant JSON examplesJohn Snow7-9/+11
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 Snow1-5/+11
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: preserve indentation in QAPIDoc sectionsJohn Snow3-23/+40
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 Snow1-26/+38
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.

2024-07-05gdbstub: Add support for MTE in user modeGustavo Romero6-1/+288
This commit implements the stubs to handle the qIsAddressTagged, qMemTag, and QMemTag GDB packets, allowing all GDB 'memory-tag' subcommands to work with QEMU gdbstub on aarch64 user mode. It also implements the get/set functions for the special GDB MTE register 'tag_ctl', used to control the MTE fault type at runtime.

2024-07-05target/arm: Factor out code for setting MTE TCF0 fieldGustavo Romero5-29/+71
Factor out the code used for setting the MTE TCF0 field from the prctl code into a convenient function. Other subsystems, like gdbstub, need to set this field as well, so keep it as a separate function to avoid duplication and ensure consistency in how this field is set across the board.

2024-07-05gdbstub: Add support for target-specific stubsGustavo Romero2-6/+118
Currently, it's not possible to have stubs specific to a given target, even though there are GDB features which are target-specific, like, for instance, memory tagging. This commit introduces gdb_extend_qsupported_features, gdb_extend_query_table, and gdb_extend_set_table functions as interfaces to extend the qSupported string, the query handler table, and the set handler table, allowing target-specific stub implementations.

Move GdbCmdParseEntry and its associated types into a separate header file to allow the use of GdbCmdParseEntry and other gdbstub command functions outside of gdbstub.c. Since GdbCmdParseEntry and get_param are now public, kdoc GdbCmdParseEntry and rename get_param to gdb_get_cmd_param.
