2020-10-17target/mips/cpu: Display warning when CPU is used without input clockPhilippe Mathieu-Daudé
All our QOM users provides an input clock. In order to avoid avoid future machines added without clock, display a warning. User-mode emulation use the CP0 timer with the RDHWR instruction (see commit cdfcad788394) so keep using the fixed 200 MHz clock without diplaying any warning. Only display it in system-mode emulation. Signed-off-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Message-Id: <20201012095804.3335117-22-f4bug@amsat.org>

The cache operation is encoded in bits [20:18] of the instruction. The 'op' argument of helper_cache() contains the bits [20:16]. Extract the 3 bits and parse them using a switch case. This allow us to handle multiple cache types (the cache type is encoded in bits [17:16]). Previously the if() block was only checking the D-Cache (Primary Data or Unified Primary).

2020-10-15block: deprecate the sheepdog block driverDaniel P. Berrangé
This thread from a little over a year ago: http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html states that sheepdog is no longer actively developed. The only mentioned users are some companies who are said to have it for legacy reasons with plans to replace it by Ceph. There is talk about cutting out existing features to turn it into a simple demo of how to write a distributed block service. There is no evidence of anyone working on that idea: https://github.com/sheepdog/sheepdog/commits/master No real commits to git since Jan 2018, and before then just some minor technical debt cleanup. There is essentially no activity on the mailing list aside from patches to QEMU that get CC'd due to our MAINTAINERS entry. Fedora packages for sheepdog failed to build from upstream source because of the more strict linker that no longer merges duplicate global symbols. Fedora patches it to add the missing "extern" annotations and presumably other distros do to, but upstream source remains broken. There is only basic compile testing, no functional testing of the driver. Since there are no build pre-requisites the sheepdog driver is currently enabled unconditionally. This would result in configure issuing a deprecation warning by default for all users. Thus the configure default is changed to disable it, requiring users to pass --enable-sheepdog to build the driver.

Even when messages are approved, the sender is never added to the whitelist, so every future mail from the same sender continues to get stopped for moderation.

2020-10-15monitor: Fix order in monitor_cleanup()Kevin Wolf
We can only destroy Monitor objects after we're sure that they are not in use by the dispatcher coroutine any more. This fixes crashes like the following where we tried to destroy a monitor mutex while the dispatcher coroutine still holds it: (gdb) bt #0 0x00007fe541cf4bc5 in raise () at /lib64/libc.so.6 #1 0x00007fe541cdd8a4 in abort () at /lib64/libc.so.6 #2 0x000055c24e965327 in error_exit (err=16, msg=0x55c24eead3a0 <__func__.33> "qemu_mutex_destroy") at ../util/qemu-thread-posix.c:37 #3 0x000055c24e9654c3 in qemu_mutex_destroy (mutex=0x55c25133e0f0) at ../util/qemu-thread-posix.c:70 #4 0x000055c24e7cfaf1 in monitor_data_destroy_qmp (mon=0x55c25133dfd0) at ../monitor/qmp.c:439 #5 0x000055c24e7d23bc in monitor_data_destroy (mon=0x55c25133dfd0) at ../monitor/monitor.c:615 #6 0x000055c24e7d253a in monitor_cleanup () at ../monitor/monitor.c:644 #7 0x000055c24e6cb002 in qemu_cleanup () at ../softmmu/vl.c:4549 #8 0x000055c24e0d259b in main (argc=24, argv=0x7ffff66b0d58, envp=0x7ffff66b0e20) at ../softmmu/main.c:51 Reported-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20201013125027.41003-1-kwolf@redhat.com> Tested-by: Ben Widawsky <ben.widawsky@intel.com> Tested-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2020-10-15qemu-storage-daemon: Remove QemuOpts from --object parserKevin Wolf
The command line parser for --object parses the input twice: Once into QemuOpts just for detecting help options, and then again into a QDict using the keyval parser for actually creating the object. Now that the keyval parser can also detect help options, we can simplify this and remove the QemuOpts part.

2020-10-15keyval: Parse help optionsKevin Wolf
This adds a special meaning for 'help' and '?' as options to the keyval parser. Instead of being an error (because of a missing value) or a value for an implied key, they now request help, which is a new boolean output of the parser in addition to the QDict. A new parameter 'p_help' is added to keyval_parse() that contains on return whether help was requested. If NULL is passed, requesting help results in an error and all other cases work like before. Turning previous error cases into help is a compatible extension. The behaviour potentially changes for implied keys: They could previously get 'help' as their value, which is now interpreted as requesting help. This is not a problem in practice because 'help' and '?' are not a valid values for the implied key of any option parsed with keyval_parse(): * audiodev: union Audiodev, implied key "driver" is enum AudiodevDriver, "help" and "?" are not among its values * display: union DisplayOptions, implied key "type" is enum DisplayType, "help" and "?" are not among its values * blockdev: union BlockdevOptions, implied key "driver is enum BlockdevDriver, "help" and "?" are not among its values * export: union BlockExport, implied key "type" is enum BlockExportType, "help" and "?" are not among its values * monitor: struct MonitorOptions, implied key "mode" is enum MonitorMode, "help" and "?" are not among its values * nbd-server: struct NbdServerOptions, no implied key.

2020-10-15keyval: Fix parsing of ',' in value of implied keyMarkus Armbruster
The previous commit demonstrated documentation and code disagree on parsing of ',' in the value of an implied key. Fix the code to match the documentation. This breaks uses of keyval_parse() that pass an implied key and accept a value containing ','. None of the existing uses does: * audiodev: implied key "driver" is enum AudiodevDriver, none of the values contains ',' * display: implied key "type" is enum DisplayType, none of the values contains ',' * blockdev: implied key "driver is enum BlockdevDriver, none of the values contains ',' * export: implied key "type" is enum BlockExportType, none of the values contains ',' * monitor: implied key "mode" is enum MonitorMode, none of the values contains ',' * nbd-server: no implied key.

The grammar has a few issues: * key-fragment = / [^=,.]* / Prose restricts key fragments: they "must be valid QAPI names or consist only of decimal digits". Technically, '' consists only of decimal digits. The code rejects that. Fix the grammar. * val = { / [^,]* / | ',,' } Use + instead of *. Accepts the same language. * val-no-key = / [^=,]* / The code rejects an empty value. Fix the grammar. * Section "Additional syntax for use with an implied key" is confusing. Rewrite it.
