2016-12-20Move target-* CPU file into a target/ folderThomas Huth1-4/+4
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-10-12trace: introduce a formal group name for trace eventsDaniel P. Berrange21-55/+73
The declarations in the generated-tracers.h file are assuming there's only ever going to be one instance of this header, as they are not namespaced. When we have one header per event group, if a single source file needs to include multiple sets of trace events, the symbols will all clash. This change thus introduces a '--group NAME' arg to the 'tracetool' program. This will cause all the symbols in the generated header files to be given a unique namespace. If no group is given, the group name 'common' is used, which is suitable for the current usage where there is only one global trace-events file used for code generation.

With the removal of usage of the event enums from the API there is no longer any compelling reason for the separation between these files. The generated-events.h content is only ever needed from the generated-tracers.[ch] files.

2016-10-12trace: emit name <-> ID mapping in simpletrace headerDaniel P. Berrange2-16/+58
Currently simpletrace assumes that events are given IDs starting from 0, based on the order in which they appear in the trace-events file, with no gaps. When the trace-events file is split up, this assumption becomes problematic. To deal with this, extend the simpletrace format so that it outputs a table of event name <-> ID mappings. That will allow QEMU to assign arbitrary IDs to events without breaking simpletrace parsing. The v3 simple trace format was FILE HEADER EVENT TRACE RECORD 0 EVENT TRACE RECORD 1 ... EVENT TRACE RECORD N The v4 simple trace format is now FILE HEADER EVENT MAPPING RECORD 0 EVENT MAPPING RECORD 1 ... EVENT MAPPING RECORD M EVENT TRACE RECORD RECORD 0 EVENT TRACE RECORD RECORD 1 ... EVENT TRACE RECORD N Although this shows all the mapping records being emitted upfront, this is not required by the format. While the main simpletrace backend will emit all mappings at startup, the systemtap simpletrace.stp script will emit the mappings at first use. eg FILE HEADER ... EVENT MAPPING RECORD 0 EVENT TRACE RECORD RECORD 0 EVENT TRACE RECORD RECORD 1 EVENT MAPPING RECORD 1 EVENT TRACE RECORD RECORD 2 ... EVENT TRACE RECORD N This is more space efficient given that most trace records only include a subset of events. In modifying the systemtap simpletrace code, a 'begin' probe was added to emit the trace event header, so you no longer need to add '--no-header' when running simpletrace.py for systemtap generated trace files.

2016-10-12trace: remove the TraceEventID and TraceEventVCPUID enumsDaniel P. Berrange4-26/+16
The TraceEventID and TraceEventVCPUID enums constants are no longer actually used for anything critical. The TRACE_EVENT_COUNT limit is used to determine the size of the TraceEvents array, and can be removed if we just NULL terminate the array instead. The TRACE_VCPU_EVENT_COUNT limit is used as a magic value for marking non-vCPU events, and also for declaring the size of the trace dstate mask in the CPUState struct. The former usage can be replaced by a dedicated constant TRACE_EVENT_VCPU_NONE, defined as (uint32_t)-1. For the latter usage, we can simply define a constant for the number of VCPUs, avoiding the need for the full enum. The only other usages of the enum values can be replaced by accesing the id/vcpu_id fields via the named TraceEvent structs.

2016-09-19qapi: check invalid arguments on no-args commandsMarc-André Lureau1-15/+43
The generated marshal functions do not visit arguments from commands that take no arguments. Thus they fail to catch invalid members. Visit the arguments, if provided, to throw an error in case of invalid members. Currently, qmp_check_client_args() checks for invalid arguments and correctly catches this case. When switching to qmp_dispatch() we want to keep that behaviour. The commands using 'O' may have arbitrary arguments, and must have 'gen': false in the qapi schema to skip the generated checks. Old/new diff: void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp) { Error *err = NULL; + Visitor *v = NULL; - (void)args; + if (args) { + v = qmp_input_visitor_new(QOBJECT(args), true); + visit_start_struct(v, NULL, NULL, 0, &err); + if (err) { + goto out; + } + + if (!err) { + visit_check_struct(v, &err); + } + visit_end_struct(v, NULL); + if (err) { + goto out; + } + } qmp_stop(&err); + +out: error_propagate(errp, err); + visit_free(v); + if (args) { + v = qapi_dealloc_visitor_new(); + visit_start_struct(v, NULL, NULL, 0, NULL); + + visit_end_struct(v, NULL); + visit_free(v); + } } The new code closely resembles code for a command with arguments. Differences: - the visit of the argument and its cleanup struct don't visit any members (because there are none). - the visit of the argument struct and its cleanup are conditional.

Furthermore, even most WARNs have been bumped to errors, with WARN only reserved to things that patchew probably ought not to complain about (and that maintainers probably will notice anyway during review if they are extreme). Default to exiting with success even if there are WARN-level failures, and cause --strict to fail for warnings. Maintainers that want to have a strict 80-character limit for their subsystem can add it to a commit hook for example. The --subjective synonym is removed.

2016-08-10checkpatch: bump most warnings to errorsPaolo Bonzini1-33/+33
This only leaves a warning-level message for the extra-long lines soft limit. Everything else is bumped up. In the future warnings can be added for checks that can have false positives. Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-08-10CODING_STYLE, checkpatch: update line length rulesPaolo Bonzini1-2/+6
Line lengths above 80 characters do exist. They are rare, but they happen from time to time. An ignored rule is worse than an exception to the rule, so do the latter. Some on the list expressed their preference for a soft limit that is slightly lower than 80 characters, to account for extra characters in unified diffs (including three-way diffs) and for email quoting. However, there was no consensus on this so keep the 80-character soft limit and add a hard limit at 90.

2016-08-09checkpatch: ignore automatically imported Linux headersRadim Krčmář1-0/+3
Linux uses tabs for indentation and checkpatch always complained about automatically imported headers. update-linux-headers.sh could be modified to expand tabs, but there is no real reason to complain about any ugly code in Linux headers, so skip all hunk-related checks.

2016-08-09linuxboot_dma: avoid guest ABI breakage on gcc vs. clang compilationPaolo Bonzini1-16/+11
Recent GCC compiles linuxboot_dma.c to 921 bytes, while CentOS 6 needs 1029 and clang needs 1527. Because the size of the ROM, rounded to the next 512 bytes, must match, this causes the API to break between a <1K ROM and one that is bigger. We want to make the ROM 1.5 KB in size, but it's better to make clang produce leaner ROMs, because currently it is worryingly close to the limit. To fix this prevent clang's happy inlining (which -Os cannot prevent). This only requires adding a noinline attribute. Second, the patch makes sure that the ROM has enough padding to prevent ABI breakage on different compilers. The size is now hardcoded in the file that is passed to signrom.py, as was the case before commit 6f71b77 ("scripts/signrom.py: Allow option ROM checksum script to write the size header.", 2016-05-23); signrom.py however will still pad the input to the requested size. This ensures that the padding goes beyond the next multiple of 512 if necessary, and also avoids the need for -fno-toplevel-reorder which clang doesn't support. signrom.py can then error out if the requested size is too small for the actual size of the compiled ROM.

2016-08-08checkpatch: Fix newline detection in error_setg() & friendsMarkus Armbruster1-1/+4
Commit 5d596c2's regexp assumes the error message string is the first argument. Correct for error_report(), wrong for all the others. Relax the regexp to match newline in anywhere. This might cause additional false positives. While there, update the list of error_reporting functions. Cc: Jason J.
