2023-04-24qapi: Require boxed for conditional command and event argumentsMarkus Armbruster
The C code generator fails to honor 'if' conditions of command and event arguments. For instance, tests/qapi-schema/qapi-schema-test.json has { 'event': 'TEST_IF_EVENT', 'data': { 'foo': 'TestIfStruct', 'bar': { 'type': ['str'], 'if': 'TEST_IF_EVT_ARG' } }, 'if': { 'all': ['TEST_IF_EVT', 'TEST_IF_STRUCT'] } } Generated tests/test-qapi-events.h fails to honor the TEST_IF_EVT_ARG condition: #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) void qapi_event_send_test_if_event(TestIfStruct *foo, strList *bar); #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */ Only uses so far are in tests/. We could fix the generator to emit something like #if defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) void qapi_event_send_test_if_event(TestIfStruct *foo #if defined(TEST_IF_EVT_ARG) , strList *bar #endif ); #endif /* defined(TEST_IF_EVT) && defined(TEST_IF_STRUCT) */ Ugly. Calls become similarly ugly. Not worth fixing. Conditional arguments work fine with 'boxed': true, simply because complex types with conditional members work fine. Not worth breaking. Reject conditional arguments unless boxed. Move the tests cases covering unboxed conditional arguments out of tests/qapi-schema/qapi-schema-test.json. Cover boxed conditional arguments there instead.

2023-04-21docs: vhost-user: Add Xen specific memory mapping supportViresh Kumar
The current model of memory mapping at the back-end works fine where a standard call to mmap() (for the respective file descriptor) is enough before the front-end can start accessing the guest memory. There are other complex cases though where the back-end needs more information and simple mmap() isn't enough. For example Xen, a type-1 hypervisor, currently supports memory mapping via two different methods, foreign-mapping (via /dev/privcmd) and grant-dev (via /dev/gntdev). In both these cases, the back-end needs to call mmap() and ioctl(), with extra information like the Xen domain-id of the guest whose memory we are trying to map. Add a new protocol feature, 'VHOST_USER_PROTOCOL_F_XEN_MMAP', which lets the back-end know about the additional memory mapping requirements. When this feature is negotiated, the front-end will send the additional information within the memory regions themselves.

The same layout is defined twice, once in "single memory region description" and then in "memory regions description". Separate out details of memory region from these two and reuse the same definition later on. While at it, also rename "memory regions description" to "multiple memory regions description", to avoid potential confusion around similar names. And define single region before multiple ones. This is just a documentation optimization, the protocol remains the same.

2023-04-20docs/devel/kconfig.rst: Fix incorrect markupPeter Maydell
In rST markup syntax, the inline markup (*italics*, **bold** and ``monospaced``) must be separated from the surrending text by non-word characters, otherwise it is not interpreted as markup. To force interpretation as markup in the middle of a word, you need to use a backslash-escaped space (which will not appear as a space in the output). Fix a missing backslash-space in this file, which meant that the `` after "select" was output literally and the monospacing was incorrectly extended all the way to the end of the next monospaced word.

2023-04-20target/arm: Implement FEAT_PAN3Peter Maydell
FEAT_PAN3 adds an EPAN bit to SCTLR_EL1 and SCTLR_EL2, which allows the PAN bit to make memory non-privileged-read/write if it is user-executable as well as if it is user-read/write. Implement this feature and enable it in the AArch64 'max' CPU.

2023-04-20docs: explain effect of smp_read_barrier_depends() on modern architecturesPaolo Bonzini
The documentation for smp_read_barrier_depends() does not mention the architectures for which it is an optimization, for example ARM and PPC. As a result, it is not clear to the reader why one would use it. Relegate Alpha to a footnote together with other architectures where it is equivalent to smp_rmb().

2023-03-24Revert "docs/about/deprecated: Deprecate 32-bit arm hosts for system emulation"Thomas Huth
This reverts commit 1d0a8eba38cdddd028ea02c6e0b68f0a4c9a3cbf. The commit made the wrong assumption that 64-bit distros are most common these days on arm devices, but as Liviu Ionescu pointed out, the recommended OS for the very popular Raspberry Pi boards is still the 32-bit variant, and thus likely still used by a lot of people: https://www.raspberrypi.com/software/operating-systems/ Thus it's likely still a little bit too early to put this host environment on the deprecation list and we should wait a little bit longer 'til 64-bit distros are the predominant ones.

2023-03-16docs/sphinx/kerneldoc.py: Honour --enable-werrorPeter Maydell
Currently, the kerneldoc Sphinx plugin doesn't honour the --enable-werror configure option, so its warnings are never fatal. This is because although we do pass sphinx-build the -W switch, the warnings from kerneldoc are produced by the scripts/kernel-doc script directly and don't go through Sphinx's "emit a warning" function. When --enable-werror is in effect, pass sphinx-build an extra argument -Dkerneldoc_werror=1. The kerneldoc plugin can then use this to determine whether it should be passing the kernel-doc script -Werror. We do this because there is no documented mechanism for a Sphinx plugin to determine whether sphinx-build was passed -W or not; if one is provided then we can switch to that at a later date: https://github.com/sphinx-doc/sphinx/issues/11239 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Thomas Huth <thuth@redhat.com> Message-Id: <20230314114431.1096972-1-peter.maydell@linaro.org> Signed-off-by: Laurent Vivier <laurent@vivier.eu>

Configuring the accelerator should nowadays be done via the "-accel" command line parameter, and thus via the "[accel]" section in config files. We also need this change for the upcoming qtests that will use these config files, since the qtests are already using "-accel" for setting the "qtest" accelerator and QEMU does not like mixing "-accel ..." and "-machine accel=...".

2023-03-08docs/about/deprecated: Deprecate 32-bit arm hosts for system emulationThomas Huth
For running QEMU in system emulation mode, the user needs a rather strong host system, i.e. not only an embedded low-frequency controller. All recent beefy arm host machines should support 64-bit now, it's unlikely that anybody is still seriously using QEMU on a 32-bit arm CPU, so we deprecate the 32-bit arm hosts here to finally save use some time and precious CI minutes.

2023-03-07docs/about/build-platforms: Refine the distro support policyThomas Huth
For long-term distributions that release a new version only very seldom, we limit the support to five years after the initial release. Otherwise, we might need to support distros like openSUSE 15 for up to 7 or even more years in total due to our "two more years after the next major release" rule, which is just way too much to handle in a project like QEMU that only has limited human resources.

2023-03-07qatomic: add smp_mb__before/after_rmw()Paolo Bonzini
On ARM, seqcst loads and stores (which QEMU does not use) are compiled respectively as LDAR and STLR instructions. Even though LDAR is also used for load-acquire operations, it also waits for all STLRs to leave the store buffer. Thus, LDAR and STLR alone are load-acquire and store-release operations, but LDAR also provides store-against-load ordering as long as the previous store is a STLR. Compare this to ARMv7, where store-release is DMB+STR and load-acquire is LDR+DMB, but an additional DMB is needed between store-seqcst and load-seqcst (e.g. DMB+STR+DMB+LDR+DMB); or with x86, where MOV provides load-acquire and store-release semantics and the two can be reordered. Likewise, on ARM sequentially consistent read-modify-write operations only need to use LDAXR and STLXR respectively for the load and the store, while on x86 they need to use the stronger LOCK prefix. In a strange twist of events, however, the _stronger_ semantics of the ARM instructions can end up causing bugs on ARM, not on x86. The problems occur when seqcst atomics are mixed with relaxed atomics. QEMU's atomics try to bridge the Linux API (that most of the developers are familiar with) and the C11 API, and the two have a substantial difference: - in Linux, strongly-ordered atomics such as atomic_add_return() affect the global ordering of _all_ memory operations, including for example READ_ONCE()/WRITE_ONCE() - in C11, sequentially consistent atomics (except for seq-cst fences) only affect the ordering of sequentially consistent operations. In particular, since relaxed loads are done with LDR on ARM, they are not ordered against seqcst stores (which are done with STLR). QEMU implements high-level synchronization primitives with the idea that the primitives contain the necessary memory barriers, and the callers can use relaxed atomics (qatomic_read/qatomic_set) or even regular accesses. This is very much incompatible with the C11 view that seqcst accesses are only ordered against other seqcst accesses, and requires using seqcst fences as in the following example: qatomic_set(&y, 1); qatomic_set(&x, 1); smp_mb(); smp_mb(); ... qatomic_read(&x) ... ... qatomic_read(&y) ... When a qatomic_*() read-modify write operation is used instead of one or both stores, developers that are more familiar with the Linux API may be tempted to omit the smp_mb(), which will work on x86 but not on ARM. This nasty difference between Linux and C11 read-modify-write operations has already caused issues in util/async.c and more are being found. Provide something similar to Linux smp_mb__before/after_atomic(); this has the double function of documenting clearly why there is a memory barrier, and avoiding a double barrier on x86 and s390x systems. The new macro can already be put to use in qatomic_mb_set().
