2020-09-29scripts/texi2pod: Delete unused scriptPeter Maydell2-537/+1
We no longer need the texi2pod script, so we can delete it, and the special-casing it had in the checkpatch script.

2020-09-29docs/devel/qapi-code-gen.txt: Update to new rST backend conventionsPeter Maydell1-26/+49
Update the documentation of QAPI document comment syntax to match the new rST backend requirements. The principal changes are: * whitespace is now significant, and multiline definitions must have their second and subsequent lines indented to match the first line * general rST format markup is permitted, not just the small set of markup the old texinfo generator handled. For most things (notably bulleted and itemized lists) the old format was the same as rST is. * Specific things that might trip people up: - instead of *bold* and _italic_ rST has **bold** and *italic* - lists need a preceding and following blank line - a lone literal '*' will need to be backslash-escaped to avoid a rST syntax error * the old leading '|' for example (literal text) blocks is replaced by the standard rST '::' literal block. * we support arbitrary levels of sub- and sub-sub-heading, not just a main and sub-heading like the old texinfo generator * lists can now be nested Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-Id: <20200925162316.21205-18-peter.maydell@linaro.org> Reviewed-by: Markus Armbruster <armbru@redhat.com> [Commit message improved slightly] Signed-off-by: Markus Armbruster <armbru@redhat.com>

2020-09-29tests/qapi-schema: Add test of the rST QAPI doc-comment outputPeter Maydell3-0/+348
Add a test of the rST output from the QAPI doc-comment generator, similar to what we currently have that tests the Texinfo output. This is a bit more awkward with Sphinx, because the generated output is not 100% under our control the way the QAPI-to-Texinfo generator was. We can't observe the data we generate, only the Sphinx output. Two issues. One, the output can vary with the Sphinx version. In practice Sphinx's plaintext output generation has been identical between at least Sphinx 1.6 and 3.0, so we use that. (The HTML output has had changes across versions). We use an exact-match comparison check, with the understanding that perhaps changes in a future Sphinx version might require us to implement something more clever to cope with variation in the output. Two, the test can only protect us from changes in the data we generate that are visible in plain text.

2020-09-29meson.build: Make manuals depend on source to Sphinx extensionsPeter Maydell2-0/+9
The automatic dependency handling for Sphinx manuals only makes the output depend on the input documentation files. This means that if you edit the Python source of an extension then the documentation won't be rebuilt. Create a list of all the source files for the extensions and add it to the dependencies for the manuals. This is similar to how we handle the qapi_gen_depends list. Because we don't try to identify which manuals are using which Sphinx extensions, a change to the source of one extension will always rebuild the entire manual set, not merely the manuals which have changed. This is acceptable because we don't change the extensions all that often.

2020-09-29tests/qapi-schema: Convert doc-good.json to rST-style strong/emphasisPeter Maydell3-3/+3
doc-good.json currently uses the old *strong* and _emphasis_ markup. As part of the conversion to rST this needs to switch to **strong** and *emphasis*, because rST uses underscores as part of its markup of hyperlinks and will otherwise warn about the syntax error. In commit a660eed482063b we fixed up the in-tree uses of the old markup: 1) _this_ was replaced with *this* 2) the only in-tree use of *this* was left alone (turning a 'strong' into an 'emphasis') (and so currently in-tree nothing is using either new-style **strong** or old-style _emphasis_). Update doc-good.json in a similar way: 1) replace _this_ with *this* 2) remove the usage of old-style *this* (This slightly reduces the coverage for the old Texinfo generator, which is about to go away, but is fine for the new rST generator because that does not need to handle strong/emphasis itself because it is simply passing the entire text as raw rST to Sphinx.)

2020-09-29qapi: Use rST markup for literal blocksPeter Maydell2-9/+13
There are exactly two places in our json doc comments where we use the markup accepted by the texi doc generator where a '|' in the first line of a doc comment means the line should be emitted as a literal block (fixed-width font, whitespace preserved). Since we use this syntax so rarely, instead of making the rST generator support it, instead just convert the two uses to rST-format literal blocks, which are indented and introduced with '::'. (The rST generator doesn't complain about the old style syntax, it just emits it with the '|' and with the whitespace not preserved, which looks odd, but means we can safely leave this change until after we've stopped generating texinfo.)

Convert qemu-qmp-ref to rST format. This includes dropping the plain-text, pdf and info format outputs for this document; as with all our other Sphinx-based documentation, we provide HTML and manpage only. The qemu-qmp-ref.rst is somewhat more stripped down than the .texi was, because we do not (currently) attempt to generate indexes for the commands, events and data types being documented. Again, we drop the direct link from index.html.in now that the QMP ref is part of the interop manual. This commit removes the code from the root meson.build file that handled the various Texinfo-based outputs, because we no longer generate any documentation except for the Sphinx HTML manuals and the manpages, and the code can't handle having an empty list of files to process..

2020-09-29docs/sphinx: Add new qapi-doc Sphinx extensionPeter Maydell3-1/+556
Some of our documentation is auto-generated from documentation comments in the JSON schema. 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 processes the JSON file and inserts documentation into the rST file being processed. This is the same approach that kerneldoc and hxtool use.

2020-09-29scripts/qapi/parser.py: improve doc comment indent handlingPeter Maydell7-21/+109
Make the handling of indentation in doc comments more sophisticated, so that when we see a section like: Notes: some text some more text indented line 3 we save it for the doc-comment processing code as: some text some more text indented line 3 and when we see a section with the heading on its own line: Notes: some text some more text indented text we also accept that and save it in the same form. If we detect that the comment document text is not indented as much as we expect it to be, we throw a parse error. (We don't complain about over-indented sections, because for rST this can be legitimate markup.) The golden reference for the doc comment text is updated to remove the two 'wrong' indents; these now form a test case that we correctly stripped leading whitespace from an indented multi-line argument definition. We update the documentation in docs/devel/qapi-code-gen.txt to describe the new indentation rules.

2020-09-29scripts/qapi: Move doc-comment whitespace stripping to doc.pyPeter Maydell3-14/+11
As we accumulate lines from doc comments when parsing the JSON, the QAPIDoc class generally strips leading and trailing whitespace using line.strip() when it calls _append_freeform(). This is fine for Texinfo, but for rST leading whitespace is significant. We'd like to move to having the text in doc comments be rST format rather than a custom syntax, so move the removal of leading whitespace from the QAPIDoc class to the texinfo-specific processing code in texi_format() in qapi/doc.py. (Trailing whitespace will always be stripped by the rstrip() in Section::append regardless.) In a followup commit we will make the whitespace in the lines of doc comment sections more consistently follow the input source. There is no change to the generated .texi files before and after this commit. Because the qapi-schema test checks the exact values of the documentation comments against a reference, we need to update that reference to match the new whitespace. In the first four places this is now correctly checking that we did put in the amount of whitespace to pass a rST-formatted list to the backend; in the last two places the extra whitespace is 'wrong' and will go away again in the following commit.

doc-good.json tests doc comment parser corner cases. We're about to largely replace it by a Sphinx extension, which will have different corner cases. Tweak the test so it passes both with the old parser and the Sphinx extension, by making it match the more restrictive rST syntax: * in a single list the bullet types must all match * lists must have leading and following blank lines * the rules on when and where indentation matters differ * the '|' example syntax is going to go away entirely, so stop testing it This will avoid the tests spuriously breaking when we tighten up the parser code in the following commits.

2020-09-29tests/acpi: update golden master DSDT binary table blobs for q35Ani Sinha303-10/+71489
In the previously applied commit ("piix4: don't reserve hw resources when hotplug is off globally"), we make changes to the ACPI DSDT tables such that some ACPI code are not generated when bsel is absent. Since as of this point in time, in q35 machines, we do not use bsel for pci buses, we need to update the DSDT table blobs. This patch updates the DSDT golden master tables for q35 machines. At the same time, we clear bios-tables-test-allowed-diff.h for future changes which update tables.

2020-09-29piix4: don't reserve hw resources when hotplug is off globallyAni Sinha2-9/+22
When acpi hotplug is turned off for both root pci bus as well as for pci bridges, we should not generate the related ACPI code for DSDT table or initialize related hw ports or reserve hw resources. This change makes sure all those operations are turned off in the case ACPI pci hotplug is off globally. In this change, we also make sure ACPI code for the PCNT method are only added when bsel is enabled for the corresponding pci bus or bridge hotplug is turned on. As q35 machines do not use bsel for it's pci buses at this point in time, this change affects DSDT acpi table for q35 machines as well. Therefore, we will also need to commit the updated golden master DSDT table acpi binary blobs as well. Following is the list of blobs which needs updating: tests/data/acpi/q35/DSDT tests/data/acpi/q35/DSDT.acpihmat tests/data/acpi/q35/DSDT.bridge tests/data/acpi/q35/DSDT.cphp tests/data/acpi/q35/DSDT.dimmpxm tests/data/acpi/q35/DSDT.ipmibt tests/data/acpi/q35/DSDT.memhp tests/data/acpi/q35/DSDT.mmio64 tests/data/acpi/q35/DSDT.numamem tests/data/acpi/q35/DSDT.tis These tables are updated in the following commit.

2020-09-29tests/acpi: unit test for 'acpi-pci-hotplug-with-bridge-support' bridge flagAni Sinha1-0/+16
This change adds a new unit test for the global flag 'acpi-pci-hotplug-with-bridge-support' which is available for cold plugged pci bridges in i440fx. The flag can be used to turn off ACPI based hotplug support on all pci bridges.

2020-09-29i440fx/acpi: do not add hotplug related amls for cold plugged bridgesAni Sinha1-6/+6
Cold plugged bridges are not hot unpluggable, even when their hotplug property (acpi-pci-hotplug-with-bridge-support) is turned off. Please see the function acpi_pcihp_pc_no_hotplug(). However, with the current implementaton, Windows would try to hot-unplug a pci bridge when it's hotplug switch is off. This is regardless of whether there are devices attached to the bridge. This is because we add ACPI code like _EJ0 etc for the pci slot where the bridge is cold plugged. In this fix, we identify a cold plugged bridge and for cold plugged bridges, we do not add the appropriate ACPI methods that are used by the OS to identify a hot-pluggable/unpluggable pci device. After this change, Windows does not detect the cold plugged pci bridge as ejectable. As a result of the patch, the following are the changes to the DSDT ACPI table: @@ -858,38 +858,33 @@ Return (Zero) } Method (_S2D, 0, NotSerialized) // _S2D: S2 Device State { Return (Zero) } Method (_S3D, 0, NotSerialized) // _S3D: S3 Device State { Return (Zero) } } Device (S18) { - Name (_SUN, 0x03) // _SUN: Slot User Number Name (_ADR, 0x00030000) // _ADR: Address - Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device - { - PCEJ (BSEL, _SUN) - } } Device (S20) { Name (_SUN, 0x04) // _SUN: Slot User Number Name (_ADR, 0x00040000) // _ADR: Address Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device { PCEJ (BSEL, _SUN) } } Device (S28) { Name (_SUN, 0x05) // _SUN: Slot User Number Name (_ADR, 0x00050000) // _ADR: Address @@ -1148,37 +1143,32 @@ PCEJ (BSEL, _SUN) } } Device (SF8) { Name (_SUN, 0x1F) // _SUN: Slot User Number Name (_ADR, 0x001F0000) // _ADR: Address Method (_EJ0, 1, NotSerialized) // _EJx: Eject Device { PCEJ (BSEL, _SUN) } } Method (DVNT, 2, NotSerialized) { - If ((Arg0 & 0x08)) - { - Notify (S18, Arg1) - } - If ((Arg0 & 0x10)) { Notify (S20, Arg1) } If ((Arg0 & 0x20)) { Notify (S28, Arg1) } If ((Arg0 & 0x40)) { Notify (S30, Arg1) } If ((Arg0 & 0x80)) While at it, I have also updated a stale comment.
