2023-09-21target/arm: Enable FEAT_MOPS for CPU 'max'Peter Maydell1-0/+1
Enable FEAT_MOPS on the AArch64 'max' CPU, and add it to the list of features we implement. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20230912140434.1333369-13-peter.maydell@linaro.org
2023-09-21target/arm: Implement FEAT_HBCPeter Maydell1-0/+1
FEAT_HBC (Hinted conditional branches) provides a new instruction BC.cond, which behaves exactly like the existing B.cond except that it provides a hint to the branch predictor about the likely behaviour of the branch. Since QEMU does not implement branch prediction, we can treat this identically to B.cond.

2023-09-21docs/devel/loads-stores: Fix git grep regexesPeter Maydell1-20/+20
The loads-and-stores documentation includes git grep regexes to find occurrences of the various functions. Some of these regexes have errors, typically failing to escape the '?', '(' and ')' when they should be metacharacters (since these are POSIX basic REs). We also weren't consistent about whether to have a ':' on the end of the line introducing the list of regexes in each section. Fix the errors. The following shell rune will complain about any REs in the file which don't have any matches in the codebase: for re in $(sed -ne 's/ - ``\(\\<.*\)``/\1/p' docs/devel/loads-stores.rst); do git grep -q "$re" || echo "no matches for re $re"; done Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Message-id: 20230904161703.3996734-1-peter.maydell@linaro.org
2023-09-19docs: Start documenting VM templatingDavid Hildenbrand2-0/+126
Let's add some details about VM templating, focusing on the VM memory configuration only. There is much more to VM templating (VM state? block devices?), but I leave that as future work.

2023-09-19docs: Don't mention "-mem-path" in multi-process.rstDavid Hildenbrand1-2/+3
"-mem-path" corresponds to "memory-backend-file,share=off" and, therefore, creates a private COW mapping of the file. For multi-proces QEMU, we need proper shared file-backed memory. Let's make that clearer. Message-ID: <20230906120503.359863-9-david@redhat.com> Signed-off-by: David Hildenbrand <david@redhat.com>

2023-09-11vfio/migration: Add P2P support for VFIO migrationAvihai Horon1-36/+57
VFIO migration uAPI defines an optional intermediate P2P quiescent state. While in the P2P quiescent state, P2P DMA transactions cannot be initiated by the device, but the device can respond to incoming ones. Additionally, all outstanding P2P transactions are guaranteed to have been completed by the time the device enters this state. The purpose of this state is to support migration of multiple devices that might do P2P transactions between themselves. Add support for P2P migration by transitioning all the devices to the P2P quiescent state before stopping or starting the devices. Use the new VMChangeStateHandler prepare_cb to achieve that behavior. This will allow migration of multiple VFIO devices if all of them support P2P migration.

docs/multi-thread-compression.txt uses parameter names with underscores instead of dashes. Wrong since day one. docs/rdma.txt, tests/qemu-iotests/181, and tests/qtest/test-hmp.c are wrong the same way since commit cbde7be900d2 (v6.0.0).

HAX is deprecated since commits 73741fda6c ("MAINTAINERS: Abort HAXM maintenance") and 90c167a1da ("docs/about/deprecated: Mark HAXM in QEMU as deprecated"), released in v8.0.0. Per the latest HAXM release (v7.8 [*]), the latest QEMU supported is v7.2: Note: Up to this release, HAXM supports QEMU from 2.9.0 to 7.2.0. The next commit (https://github.com/intel/haxm/commit/da1b8ec072) added: HAXM v7.8.0 is our last release and we will not accept pull requests or respond to issues after this. It became very hard to build and test HAXM. Its previous maintainers made it clear they won't help. It doesn't seem to be a very good use of QEMU maintainers to spend their time in a dead project. Save our time by removing this orphan zombie code.

2023-08-30gitlab: enable ccache for many build jobsDaniel P. Berrangé1-0/+7
The `ccache` tool can be very effective at reducing compilation times when re-running pipelines with only minor changes each time. For example a fresh 'build-system-fedora' job will typically take 20 minutes on the gitlab.com shared runners. With ccache this is reduced to as little as 6 minutes. Normally meson would auto-detect existance of ccache in $PATH and use it automatically, but the way we wrap meson from configure breaks this, as we're passing in an config file with explicitly set compiler paths. Thus we need to add $CCACHE_WRAPPERSPATH to the front of $PATH. For unknown reasons if doing this in msys though, gcc becomes unable to invoke 'cc1' when run from meson. For msys we thus set CC='ccache gcc' before invoking 'configure' instead. A second problem with msys is that cache misses are incredibly expensive, so enabling ccache massively slows down the build when the cache isn't well populated. This is suspected to be a result of the cost of spawning processes under the msys architecture. To deal with this we set CCACHE_DEPEND=1 which enables ccache's 'depend_only' strategy. This avoids extra spawning of the pre-processor during cache misses, with the downside that is it less likely ccache will find a cache hit after semantically benign compiler flag changes. This is the lesser of two evils, as otherwise we can't use ccache at all under msys and remain inside the job time limit. If people are finding ccache to hurt their pipelines, it can be disabled by setting the 'CCACHE_DISABLE=1' env variable against their gitlab fork CI settings. Signed-off-by: Daniel P.

2023-08-28Revert "tests: Use separate virtual environment for avocado"Paolo Bonzini2-10/+10
This reverts commit e8e4298feadae7924cf7600bb3bcc5b0a8d7cbe9. ensuregroup allows to specify both the acceptable versions of avocado, and a locked version to be used when avocado is not installed as a system pacakge. This lets us install avocado in pyvenv/ using "mkvenv.py" and reuse the distro package on Fedora and CentOS Stream (the only distros where it's available). ensuregroup's usage of "(>=..., <=...)" constraints when evaluating the distro package, and "==" constraints when installing it from PyPI, makes it possible to avoid conflicts between the known-good version and a package plugins included in the distro. This is because package plugins have "==" constraints on the version that is included in the distro, and, using "pip install avocado==88.1" on a venv that includes system packages will result in an error: avocado-framework-plugin-varianter-yaml-to-mux 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible. avocado-framework-plugin-result-html 98.0 requires avocado-framework==98.0, but you have avocado-framework 88.1 which is incompatible. But at the same time, if the venv does not include a system distribution of avocado then we can install a known-good version and stick to LTS releases.

2023-08-23docs/about/license: Update LICENSE URLPhilippe Mathieu-Daudé1-1/+1
In early 2021 (see commit 2ad784339e "docs: update README to use GitLab repo URLs") almost all of the code base was converted to point to GitLab instead of git.qemu.org. During 2023, git.qemu.org switched from a git mirror to a http redirect to GitLab (see [1]). Update the LICENSE URL to match its previous content, displaying the file raw content similarly to gitweb 'blob_plain' format ([2]).

2023-07-26docs/migration: Update postcopy bitsPeter Xu1-26/+66
We have postcopy recovery but not reflected in the document, do an update for that. Add a very small section on postcopy preempt. Touch up the pagemap section, dropping the unsent map because it's already been dropped in the source code in commit 1e7cf8c323 ("migration/postcopy: unsentmap is not necessary for postcopy"). Touch up the postcopy section to remove "network connection" failures as downside, because now it's not fatal and can be recovered. Suggested by Laszlo.

2023-07-26migration: skipped field is really obsolete.Juan Quintela1-0/+10
Has return zero for more than 10 years. Specifically we introduced the field in 1.5.0 commit f1c72795af573b24a7da5eb52375c9aba8a37972 Author: Peter Lieven <pl@kamp.de> Date: Tue Mar 26 10:58:37 2013 +0100 migration: do not sent zero pages in bulk stage during bulk stage of ram migration if a page is a zero page do not send it at all. the memory at the destination reads as zero anyway. even if there is an madvise with QEMU_MADV_DONTNEED at the target upon receipt of a zero page I have observed that the target starts swapping if the memory is overcommitted. it seems that the pages are dropped asynchronously. this patch also updates QMP to return the number of skipped pages in MigrationStats. but removed its usage in 1.5.3 commit 9ef051e5536b6368a1076046ec6c4ec4ac12b5c6 Author: Peter Lieven <pl@kamp.de> Date: Mon Jun 10 12:14:19 2013 +0200 Revert "migration: do not sent zero pages in bulk stage" Not sending zero pages breaks migration if a page is zero at the source but not at the destination. This can e.g. happen if different BIOS versions are used at source and destination. It has also been reported that migration on pseries is completely broken with this patch. This effectively reverts commit f1c72795af573b24a7da5eb52375c9aba8a37972. Reviewed-by: Daniel P.

2023-07-19docs/system/target-riscv.rst: tidy CPU firmware sectionDaniel Henrique Barboza1-8/+16
This is how the content of the "RISC-V CPU firmware" section is displayed after the html is generated: "When using the sifive_u or virt machine there are three different firmware boot options: 1. -bios default - This is the default behaviour if no -bios option is included. (...) 3. -bios <file> - Tells QEMU to load the specified file as the firmware." It's all in the same paragraph, in a numbered list, and no special formatting for the options. Tidy it a bit by adding line breaks between items and its description. Remove the numbered list. And apply formatting for the options cited in the middle of the text.

Thus disable it by default by using the QEMU_TEST_FLAKY_TESTS environment variable to fence it (which we also already use in flaky qtests).
