2023-02-27scripts/checkpatch.pl: Do not allow assert(0)Philippe Mathieu-Daudé
Since commit 262a69f428 ("osdep.h: Prohibit disabling assert() in supported builds") we can not build QEMU with NDEBUG (or G_DISABLE_ASSERT) defined, thus 'assert(0)' always aborts QEMU. However some static analyzers / compilers doesn't notice NDEBUG can't be defined and emit warnings if code is used after an 'assert(0)' call. Apparently such compiler isn't as clever with G_DISABLE_ASSERT, so we can silent these warnings by using g_assert_not_reached() which is easier to read anyway. In order to avoid these annoying warnings, add a checkpatch rule to prohibit 'assert(0)'. Suggest using g_assert_not_reached() instead. For example when reverting the previous patch we get: ERROR: use g_assert_not_reached() instead of assert(0) #21: FILE: target/ppc/dfp_helper.c:124: + assert(0); /* cannot get here */ ERROR: use g_assert_not_reached() instead of assert(0) #30: FILE: target/ppc/dfp_helper.c:141: + assert(0); /* cannot get here */ total: 2 errors, 0 warnings, 16 lines checked Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230221232520.14480-3-philmd@linaro.org>
2023-02-23qapi: remove JSON value FIXMEJohn Snow
With the two major JSON-ish type hierarchies clarified for distinct purposes; QAPIExpression for parsed expressions and JSONValue for introspection data, remove this FIXME as no longer an action item. A third JSON-y data type, _ExprValue, is not meant to represent JSON in the abstract but rather only the possible legal return values from a single function, get_expr(). It isn't appropriate to attempt to merge it with either of the above two types. In theory, it may be possible to define a completely agnostic one-size-fits-all JSON type hierarchy that any other user could borrow - in practice, it's tough to wrangle the differences between invariant, covariant and contravariant types: input and output parameters demand different properties of such a structure. However, QAPIExpression serves to authoritatively type user input to the QAPI parser, while JSONValue serves to authoritatively type qapi generator *output* to be served back to client users at runtime via QMP. The AST for these two types are different and cannot be wholly merged into a unified syntax. They could, in theory, share some JSON primitive definitions. In practice, this is currently more trouble than it's worth with mypy's current expressive power. As such, declare this "done enough for now".

2023-02-23qapi/parser: add QAPIExpression typeJohn Snow
This patch creates a new type, QAPIExpression, which represents a parsed expression complete with QAPIDoc and QAPISourceInfo. This patch turns parser.exprs into a list of QAPIExpression instead, and adjusts expr.py to match. This allows the types we specify in parser.py to be "remembered" all the way through expr.py and into schema.py. Several assertions around packing and unpacking this data can be removed as a result. It also corrects a harmless typing error. Before the patch, check_exprs() allegedly takes a List[_JSONObject]. It actually takes a list of dicts of the form {'expr': E, 'info': I, 'doc': D} where E is of type _ExprValue, I is of type QAPISourceInfo, and D is of type QAPIDoc. Key 'doc' is optional. This is not a _JSONObject! Passes type checking anyway, because _JSONObject is Dict[str, object].

2023-02-23qapi: Add minor typing workaround for 3.6John Snow
Pylint under 3.6 does not believe that Collection is subscriptable at runtime. It is, making this a Pylint bug. https://github.com/PyCQA/pylint/issues/2377 They closed it as fixed, but that doesn't seem to be true as of Pylint 2.13.9, the latest version you can install under Python 3.6. 2.13.9 was released 2022-05-13, about seven months after the bug was closed. The least-annoying fix here is to just use the concret type.

Runtime check of avx512 support and benchmark for this feature are added. Compared with C version of xbzrle_encode_buffer function, avx512 version can achieve 50%-70% performance improvement on benchmarking. In addition, if dirty data is randomly located in 4K page, the avx512 version can achieve almost 140% performance gain.

2023-02-02scripts/ci: update gitlab-runner playbook to use latest runnerAlex Bennée
We were using quite and old runner on our machines and running into issues with stalling jobs. Gitlab in the meantime now reliably provide the latest packaged versions of the runner under a stable URL. This update: - creates a per-arch subdir for builds - switches from binary tarballs to deb packages - re-uses the same binary for the secondary runner - updates distro check for second to 22.04 Note this script isn't fully idempotent as we end up accumulating runners especially during testing. However we also want to be able to run twice with different GitLab keys (e.g. project and personal) so I think we just have to be mindful of that during testing.

2022-12-15block-coroutine-wrapper.py: introduce annotations that take the graph rdlockEmanuele Giuseppe Esposito
Add co_wrapper_bdrv_rdlock and co_wrapper_mixed_bdrv_rdlock option to the block-coroutine-wrapper.py script. This "_bdrv_rdlock" option takes and releases the graph rdlock when a coroutine function is created. This means that when used together with "_mixed", the function marked with co_wrapper_mixed_bdrv_rdlock will support both coroutine and non-coroutine case, and in the latter case it will create a coroutine that takes and releases the rdlock. When called from a coroutine, the caller must already hold the graph lock. Example: void co_wrapper_mixed_bdrv_rdlock bdrv_f1(); Becomes static void bdrv_co_enter_f1() { bdrv_graph_co_rdlock(); bdrv_co_function(); bdrv_graph_co_rdunlock(); } void bdrv_f1() { if (qemu_in_coroutine) { assume_graph_lock(); bdrv_co_function(); } else { qemu_co_enter(bdrv_co_enter_f1); ... } } When used alone, the function will not work in coroutine context, and when called in non-coroutine context it will create a new coroutine that takes care of taking and releasing the rdlock automatically. Example: void co_wrapper_bdrv_rdlock bdrv_f1(); Becomes static void bdrv_co_enter_f1() { bdrv_graph_co_rdlock(); bdrv_co_function(); bdrv_graph_co_rdunlock(); } void bdrv_f1() { assert(!qemu_in_coroutine()); qemu_co_enter(bdrv_co_enter_f1); ... } About their usage: - co_wrapper does not take the rdlock, so it can be used also outside the block layer. - co_wrapper_mixed will be used by many blk_* functions, since the coroutine function needs to call blk_wait_while_drained() and the rdlock *must* be taken afterwards, otherwise it's a deadlock. In the future this annotation will go away, and blk_* will use co_wrapper directly. - co_wrapper_bdrv_rdlock will be used by BlockDriver callbacks, ideally by all of them in the future. - co_wrapper_mixed_bdrv_rdlock will be used by the remaining functions that are still called by coroutine and non-coroutine context. In the future this annotation will go away, as we will split such mixed functions.

This new annotation starts just a function wrapper that creates a new coroutine. It assumes the caller is not a coroutine. It will be the default annotation to be used in the future. This is much better as c_w_mixed, because it is clear if the caller is a coroutine or not, and provides the advantage of automating the code creation. In the future all c_w_mixed functions will be substituted by co_wrapper.
