github: fix config mistake preventing repo lockdown commenting The previous commit updated the repo lockdown config to the new format: commit 9b89cdb2a5064a87b8a7172fa1748d46aa37a9df Author: Alex Bennée <alex.bennee@linaro.org> Date: Mon Oct 4 16:43:08 2021 +0100 .github: move repo lockdown to the v2 configuration Unfortunately the config key names used were wrong, resulting in the repo lockdown throwing warnings: Unexpected input(s) 'pull-comment', 'lock-pull', 'close-pull', valid inputs are ['github-token', 'exclude-issue-created-before', 'exclude-issue-labels', 'issue-labels', 'issue-comment', 'skip-closed-issue-comment', 'close-issue', 'lock-issue', 'issue-lock-reason', 'exclude-pr-created-before', 'exclude-pr-labels', 'pr-labels', 'pr-comment', 'skip-closed-pr-comment', 'close-pr', 'lock-pr', 'pr-lock-reason', 'process-only', 'log-output'] It still locked down the pull requests, due to its default config, but didn't leave the friendly message explaining why.

.gitlab/issue_templates: Move suggestions into comments Many users forget to remove the suggestions from the bug template when creating a new issue. So when searching for strings like "s390x" or "Windows", you get a lot of unrelated issues in the results. Thus let's move the suggestions into HTML comments - so they will still show up in the markdown when editing the bug, while being hidden/ignored in the final text or in the search queries.

backends/iommufd: Remove mutex Coverity reports a concurrent data access violation because be->users is being accessed in iommufd_backend_can_be_deleted() without holding the mutex. However, these routines are called from the QEMU main thread when a device is created. In this case, the code paths should be protected by the BQL lock and it should be safe to drop the IOMMUFD backend mutex. Simply remove it.

system/cpus: rename qemu_mutex_lock_iothread() to bql_lock() The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.

nbd/server: introduce NBDClient->lock to protect fields NBDClient has a number of fields that are accessed by both the export AioContext and the main loop thread. When the AioContext lock is removed these fields will need another form of protection. Add NBDClient->lock and protect fields that are accessed by both threads. Also add assertions where possible and otherwise add doc comments stating assumptions about which thread and lock holding. Note this patch moves the client->recv_coroutine assertion from nbd_co_receive_request() to nbd_trip() where client->lock is held.

net: handle QIOTask completion to report useful error message The network stream backend uses the async QIO socket APIs for listening and connecting sockets. It does not check the task object completion status, however, instead just looking at whether the socket FD is -1 or not. By checking the task completion, we can set a useful error message for users instead of the non-actionable "connection error" string. eg so users will see: (qemu) info network net: index=0,type=stream,error: Failed to connect to '/foo.unix': No such file or directory Signed-off-by: "Daniel P.

cpus: stop vm in suspended runstate Currently, a vm in the suspended state is not completely stopped. The VCPUs have been paused, but the cpu clock still runs, and runstate notifiers for the transition to stopped have not been called. This causes problems for live migration. Stale cpu timers_state is saved to the migration stream, causing time errors in the guest when it wakes from suspend, and state that would have been modified by runstate notifiers is wrong. Modify vm_stop to completely stop the vm if the current state is suspended, transition to RUN_STATE_PAUSED, and remember that the machine was suspended. Modify vm_start to restore the suspended state. This affects all callers of vm_stop and vm_start, notably, the qapi stop and cont commands: old behavior: RUN_STATE_SUSPENDED --> stop --> RUN_STATE_SUSPENDED new behavior: RUN_STATE_SUSPENDED --> stop --> RUN_STATE_PAUSED RUN_STATE_PAUSED --> cont --> RUN_STATE_SUSPENDED For example: (qemu) info status VM status: paused (suspended) (qemu) stop (qemu) info status VM status: paused (qemu) system_wakeup Error: Unable to wake up: guest is not in suspended state (qemu) cont (qemu) info status VM status: paused (suspended) (qemu) system_wakeup (qemu) info status VM status: running Suggested-by: Peter Xu <peterx@redhat.com> Signed-off-by: Steve Sistare <steven.sistare@oracle.com> Reviewed-by: Peter Xu <peterx@redhat.com> Link: https://lore.kernel.org/r/1704312341-66640-3-git-send-email-steven.sistare@oracle.com Signed-off-by: Peter Xu <peterx@redhat.com> | 2 年前 | |

qom/object: Limit type names to alphanumerical and some few special characters QOM names currently don't have any enforced naming rules. This can be problematic, e.g. when they are used on the command line for the "-device" option (where the comma is used to separate properties). To avoid that such problematic type names come in again, let's restrict the set of acceptable characters during the type registration. Ideally, we'd apply here the same rules as for QAPI, i.e. all type names should begin with a letter, and contain only ASCII letters, digits, hyphen, and underscore. However, we already have so many pre-existing types like: 486-x86_64-cpu cfi.pflash01 power5+_v2.1-spapr-cpu-core virt-2.6-machine pc-i440fx-3.0-machine ... so that we have to allow "." and "+" for now, too. While the dot is used in a lot of places, the "+" can fortunately be limited to two classes of legacy names ("power" and "Sun-UltraSparc" CPUs). We also cannot enforce the rule that names must start with a letter yet, since there are lot of types that start with a digit. Still, at least limiting the first characters to the alphanumerical range should be way better than nothing.

system/cpus: rename qemu_mutex_lock_iothread() to bql_lock() The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.

vhost-user: Fix protocol feature bit conflict The VHOST_USER_PROTOCOL_F_XEN_MMAP feature bit was defined in f21e95ee97d, which has been part of qemu's 8.1.0 release. However, it seems it was never added to qemu's code, but it is well possible that it is already used by different front-ends outside of qemu (i.e., Xen). VHOST_USER_PROTOCOL_F_SHARED_OBJECT in contrast was added to qemu's code in 16094766627, but never defined in the vhost-user specification. As a consequence, both bits were defined to be 17, which cannot work. Regardless of whether actual code or the specification should take precedence, F_XEN_MMAP is already part of a qemu release, while F_SHARED_OBJECT is not. Therefore, bump the latter to take number 18 instead of 17, and add this to the specification. Take the opportunity to add at least a little note on the VhostUserShared structure to the specification. This structure is referenced by the new commands introduced in 16094766627, but was not defined.

The rules are basically lifted from tests/fp/meson.build, with a few changes to create platform.h and publish a dependency. The build defines are passed through a subproject option, and posted back to users of the library via the dependency's compile_args. The only remaining user of GIT_SUBMODULES and GIT_SUBMODULES_ACTION is roms/SLOF, which is used to build pc-bios/s390-ccw.

tcg/LICENSE: Remove out of date claim about TCG subdirectory licensing Since 2008 the tcg/LICENSE file has not changed: it claims that everything under tcg/ is BSD-licensed. This is not true and hasn't been true for years: in 2013 we accepted the tcg/aarch64 target code under a GPLv2-or-later license statement. We also have generic vector optimisation code under the LGPL2.1-or-later, and the TCI backend is GPLv2-or-later. Further, many of the files are not BSD licensed but MIT licensed. We don't really consider the tcg subdirectory to be a distinct part of QEMU anyway. Remove the LICENSE file, since claiming false information about the license of the code is confusing. Update the main project LICENSE file also to be clearer about the licenses used by TCG.

Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/block*.json.

system/cpus: rename qemu_mutex_lock_iothread() to bql_lock() The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.

util/event-loop-base: Introduce options to set the thread pool size The thread pool regulates itself: when idle, it kills threads until empty, when in demand, it creates new threads until full. This behaviour doesn't play well with latency sensitive workloads where the price of creating a new thread is too high. For example, when paired with qemu's '-mlock', or using safety features like SafeStack, creating a new thread has been measured take multiple milliseconds. In order to mitigate this let's introduce a new 'EventLoopBase' property to set the thread pool size. The threads will be created during the pool's initialization or upon updating the property's value, remain available during its lifetime regardless of demand, and destroyed upon freeing it. A properly characterized workload will then be able to configure the pool to avoid any latency spikes.

block: Mark bdrv_get_specific_info() and callers GRAPH_RDLOCK This adds GRAPH_RDLOCK annotations to declare that callers of bdrv_get_specific_info() need to hold a reader lock for the graph. This removes an assume_graph_lock() call in vmdk's implementation.

qemu-keymap: properly check return from xkb_keymap_mod_get_index We can return XKB_MOD_INVALID for AltGr which rightly gets flagged by sanitisers as an overly wide shift attempt. Properly check the return type and leave the bitmap as zero in that case. Tested output before and after is unchanged with the gb and ara keymaps.

nsis installer: Fix mouse-over descriptions for emulators We use the nsis.py script to write out an installer script Section for each emulator executable, so the exact set of Sections depends on which executables were built. However the part of qemu.nsi which specifies mouse-over descriptions for each Section still has a hard-coded and very outdated list (with just i386 and alpha). This causes two problems. Firstly, if you build the installer for a configuration where you didn't build the i386 binaries you get warnings like this: warning 6000: unknown variable/constant "{Section_i386}" detected, ignoring (macro:_==:1) warning 6000: unknown variable/constant "{Section_i386w}" detected, ignoring (macro:_==:1) (this happens in our gitlab CI jobs, for instance). Secondly, most of the emulators in the generated installer don't have any mouseover text. Make nsis.py generate a second output file which has the necessary MUI_DESCRIPTION_TEXT lines for each Section it creates, so we can include that at the right point in qemu.nsi to set the mouse-over text.

=========== QEMU 自述文件
QEMU 是一款通用的开源机器与用户空间仿真器及虚拟化工具。
QEMU 能够通过纯软件方式仿真完整的机器，无需任何硬件虚拟化支持。借助动态翻译技术，它可实现出色的性能。QEMU 还能与 Xen 和 KVM hypervisor 集成，在提供仿真硬件的同时，让 hypervisor 管理 CPU。在 hypervisor 的支持下，QEMU 的 CPU 性能可接近原生水平。当 QEMU 直接仿真 CPU 时，它能够在一台机器（例如 x86_64 个人计算机主板）上运行为另一台机器（例如 ARMv7 开发板）设计的操作系统。
QEMU 还能够为 Linux 和 BSD 内核接口提供用户空间 API 虚拟化。这使得针对一种架构 ABI（例如 Linux PPC64 ABI）编译的二进制文件，可以在使用不同架构 ABI（例如 Linux x86_64 ABI）的主机上运行。这一过程不涉及任何硬件仿真，仅包含 CPU 和系统调用仿真。
QEMU 旨在满足多种使用场景。用户可直接调用它，以完全控制其行为和设置。它还致力于通过提供稳定的命令行界面和监控 API，方便集成到更高级别的管理层中。在使用 oVirt、OpenStack 和 virt-manager 等开源应用程序时，通常通过 libvirt 库间接调用 QEMU。
QEMU 整体以 GNU 通用公共许可证第 2 版发布。有关完整的许可详情，请查阅 LICENSE 文件。
文档
文档可在以下在线地址获取：
<https://www.qemu.org/documentation/>。当前开发版本的文档可在 <https://www.qemu.org/docs/master/> 查看，该文档由源代码树中的 docs/ 文件夹生成，并通过 Sphinx 构建。
构建
QEMU 是一款多平台软件，旨在能够在所有现代 Linux 平台、OS-X、Win32（通过 Mingw64 工具链）以及多种其他 UNIX 目标系统上构建。构建 QEMU 的简单步骤如下：
.. code-block:: shell
mkdir build cd build ../configure make
更多信息也可通过 QEMU 网站在线获取：
<https://wiki.qemu.org/Hosts/Linux>_<https://wiki.qemu.org/Hosts/Mac>_<https://wiki.qemu.org/Hosts/W32>_
提交补丁
QEMU 源代码采用 GIT 版本控制系统进行维护。
.. code-block:: shell
git clone https://gitlab.com/qemu-project/qemu.git
提交补丁时，一种常用方法是使用 'git format-patch' 和/或 'git send-email' 来格式化邮件并将其发送至 qemu-devel@nongnu.org 邮件列表。所有提交的补丁都必须包含作者的 'Signed-off-by' 行。补丁应遵循《开发者指南》中 风格部分 规定的准则。
关于提交补丁的更多信息可通过 QEMU 网站在线获取：
<https://wiki.qemu.org/Contribute/SubmitAPatch>_<https://wiki.qemu.org/Contribute/TrivialPatches>_
QEMU 网站同样在源代码控制下进行维护。
.. code-block:: shell
git clone https://gitlab.com/qemu-project/qemu-web.git
<https://www.qemu.org/2017/02/04/the-new-qemu-website-is-up/>_
为简化上述流程，我们开发了 'git-publish' 工具，强烈建议定期贡献代码或需要发送连续补丁系列修订版的开发者使用。它同样需要正确配置 'git send-email'，且默认不会自动化所有操作，因此建议您先手动完成上述步骤至少一次。
安装说明请访问：
<https://github.com/stefanha/git-publish>_
使用 'git-publish' 的工作流程如下：
.. code-block:: shell
$ git checkout master -b my-feature $ # 进行新提交的开发工作，并为每个提交添加 'Signed-off-by' 行 $ git publish
您的补丁系列将被发送，并标记为 my-feature-v1，以便您日后参考。
发送 v2 版本：
.. code-block:: shell
$ git checkout my-feature # 同一主题分支 $ # 对提交进行修改（例如使用 'git rebase'） $ git publish
您的补丁系列将在主题中带有 'v2' 标签发送，并且 git 顶端将被标记为 my-feature-v2。
错误报告
QEMU 项目使用 GitLab issues 来跟踪错误。运行从 QEMU git 或上游发布源代码构建的代码时发现的错误，应通过以下方式报告：
<https://gitlab.com/qemu-project/qemu/-/issues>_
如果通过操作系统供应商提供的预构建二进制包使用 QEMU，建议首先向供应商自己的错误跟踪器报告错误。如果已知该错误也影响最新的上游代码，也可以通过 GitLab 报告。
