* qapi: Move include/qapi/qmp/ to include/qobject/Daniel P. Berrangé2025-02-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. Most of the headers there correspond to source files in qobject/. This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there. This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h: scripts/get_maintainer.pl now reports "QAPI" instead of "No maintainers found". Signed-off-by: Daniel P.

* target: Improve error reporting for CpuModelInfo member @propsMarkus Armbruster2024-03-121-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | query-cpu-model-comparison, query-cpu-model-baseline, and query-cpu-model-expansion take CpuModelInfo arguments. Errors in @props members of these arguments are reported for 'props', without further context. For instance, s390x rejects {"execute": "query-cpu-model-comparison", "arguments": {"modela": {"name": "z13", "props": {}}, "modelb": {"name": "z14", "props": []}}} with {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'props', expected: object"}} This is unusual; the common QAPI unmarshaling machinery would complain about 'modelb.props'. Our hand-written code to visit the @props member neglects to provide the context. Tweak it so it provides it. The command above now fails with {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'modelb.props', expected: dict"}} Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-ID: <20240305145919.2186971-4-armbru@redhat.com> Acked-by: Daniel Henrique Barboza <dbarboza@ventanamicro.com>
* target: Simplify type checks for CpuModelInfo member @propsMarkus Armbruster2024-03-121-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CpuModelInfo member @props is semantically a mapping from name to value, and syntactically a JSON object on the wire. This translates to QDict in C. Since the QAPI schema language lacks the means to express 'object', we use 'any' instead. This is QObject in C. Commands taking a CpuModelInfo argument need to check the QObject is a QDict. For arm, riscv, and s390x, the code checks right before passing the QObject to visit_start_struct(). visit_start_struct() then checks again. Delete the first check. The error message for @props that are not an object changes slightly to the the message we get for this kind of type error in other contexts. Minor improvement. Additionally, error messages about members of @props now refer to 'props.prop-name' instead of just 'prop-name'. Another minor improvement. Both changes are visible in tests/qtest/arm-cpu-features.c.

* tests/qtest: Adjust and document query-cpu-model-expansion test for armFabiano Rosas2023-05-021-3/+17
| | | | | | | | | | | | | | | | | We're about to move the 32-bit CPUs under CONFIG_TCG, so adjust the query-cpu-model-expansion test to check against the cortex-a7, which is already under CONFIG_TCG. That allows the next patch to contain only code movement. (All the test cares about is that the CPU type it's checking is one which definitely doesn't work under KVM.) While here add comments clarifying what we're testing.

Add two boolean properties that allows the feature to be turned off, on with the architected algorithm, or on with an implementation defined algorithm.
