2014-03-11qapi script: support enum type as discriminator in unionWenchao Xia3-14/+60
By default, any union will automatically generate a enum type as "[UnionName]Kind" in C code, and it is duplicated when the discriminator is specified as a pre-defined enum type in schema. After this patch, the pre-defined enum type will be really used as the switch case condition in generated C code, if discriminator is an enum field.

2014-03-11qapi script: check correctness of unionWenchao Xia1-2/+86
Since line info is remembered as QAPISchema.line now, this patch uses it as additional info for every expr in QAPISchema inside qapi.py, then improves error message with it in checking of exprs. For common union the patch will check whether base is a valid complex type if specified. For flat union it will check whether base presents, whether discriminator is found in base, whether the key of every branch is correct when discriminator is an enum type.

2014-03-03qapi: Clean up null checking in generated visitorsMarkus Armbruster1-7/+7
Visitors get passed a pointer to the visited object. The generated visitors try to cope with this pointer being null in some places, for instance like this: visit_start_optional(m, obj ? &(*obj)->has_name : NULL, "name", &err); visit_start_optional() passes its second argument to Visitor method start_optional. Three out of three methods dereference it unconditionally. I fail to see how this pointer could legitimately be null. All this useless null checking is highly redundant, which Coverity duly reports. About 200 times. Remove the useless null checks.

This patch adds loading, stamp checking and initialization of modules. The init function of dynamic module is no longer directly called as __attribute__((constructor)) in static linked version, it is called only after passed the checking of presense of stamp symbol: qemu_stamp_$RELEASEHASH where $RELEASEHASH is generated by hashing version strings and content of configure script. With this, modules built from a different tree/version/configure will not be loaded. The module loading code requires gmodule-2.0. Modules are searched under - CONFIG_MODDIR - executable folder (to allow running qemu-{img,io} in the build directory) - ../ of executable folder (to allow running system emulator in the build directory) Modules are linked under their subdir respectively, then copied to top level of build directory for above convinience, e.g.: $(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

qmp-shell hides the QMP wire protocol JSON encoding from the user. Most of the time this is helpful and makes the command-line human-friendly. Some QMP commands take a dict as an argument.

This patch allows JSON dict arguments in qmp-shell so commands like blockdev-add and nbd-server-start can be invoked: (QEMU) blockdev-add options={"driver":"file","id":"drive1",...} Note that spaces are not allowed since str.split() is used to break up the command-line arguments first.

2014-01-27trace: fix simple trace "disable" keywordStefan Hajnoczi1-1/+2
The trace-events "disable" keyword turns an event into a nop at compile-time. This is important for high-frequency events that can impact performance. The "disable" keyword is currently broken in the simple trace backend. This patch fixes the problem as follows: Trace events are identified by their TraceEventID number. When events are disabled there are two options for assigning TraceEventID numbers: 1. Skip disabled events and don't assign them a number. 2. Assign numbers for all events regardless of the disabled keyword. The simple trace backend and its binary file format uses approach #1. The tracetool infrastructure has been using approach #2 for a while. The result is that the numbers used in simple trace files do not correspond with TraceEventIDs. In trace/simple.c we assumed that they are identical and therefore emitted bogus numbers. This patch fixes the bug by using TraceEventID for trace_event_id() while sticking to approach #1 for simple trace file numbers. This preserves simple trace file format compatibility.

2014-01-26Python-lang gdb script to extract x86_64 guest vmcore from qemu coredumpLaszlo Ersek1-0/+339
When qemu dies unexpectedly, for example in response to an explicit abort() call, or (more importantly) when an external signal is delivered to it that results in a coredump, sometimes it is useful to extract the guest vmcore from the qemu process' memory image. The guest vmcore might help understand an emulation problem in qemu, or help debug the guest. This script reimplements (and cuts many features of) the qmp_dump_guest_memory() command in gdb/Python, https://sourceware.org/gdb/current/onlinedocs/gdb/Python-API.html working off the saved memory image of the qemu process. The docstring in the patch (serving as gdb help text) describes the limitations relative to the QMP command. Dependencies of qmp_dump_guest_memory() have been reimplemented as needed. I sought to follow the general structure, sticking to original function names where possible. However, keeping it simple prevailed in some places. The patch has been tested with a 4 VCPU, 768 MB, RHEL-6.4 (2.6.32-358.el6.x86_64) guest: - The script printed > guest RAM blocks: > target_start target_end host_addr message count > ---------------- ---------------- ---------------- ------- ----- > 0000000000000000 00000000000a0000 00007f95d0000000 added 1 > 00000000000a0000 00000000000b0000 00007f960ac00000 added 2 > 00000000000c0000 00000000000ca000 00007f95d00c0000 added 3 > 00000000000ca000 00000000000cd000 00007f95d00ca000 joined 3 > 00000000000cd000 00000000000d0000 00007f95d00cd000 joined 3 > 00000000000d0000 00000000000f0000 00007f95d00d0000 joined 3 > 00000000000f0000 0000000000100000 00007f95d00f0000 joined 3 > 0000000000100000 0000000030000000 00007f95d0100000 joined 3 > 00000000fc000000 00000000fc800000 00007f960ac00000 added 4 > 00000000fffe0000 0000000100000000 00007f9618800000 added 5 > dumping range at 00007f95d0000000 for length 00000000000a0000 > dumping range at 00007f960ac00000 for length 0000000000010000 > dumping range at 00007f95d00c0000 for length 000000002ff40000 > dumping range at 00007f960ac00000 for length 0000000000800000 > dumping range at 00007f9618800000 for length 0000000000020000 -

Detect presence of IASL compiler and use it to process ASL source. If not there, use pre-compiled files in-tree. Add script to update the in-tree files. Note: distros are known to silently update iasl so detect correct iasl flags for the installed version on each run as opposed to at configure time.

2013-10-14i386: add ACPI table files from seabiosMichael S. Tsirkin2-0/+413
This adds ASL code as well as scripts for processing it, imported from seabios git tree commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd Will be used for runtime acpi table generation. Note: This patch reuses some code from SeaBIOS, which was originally under LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This relicensing has been acked by all contributors that had contributed to the code since the v2->v3 relicense. ACKs approving the v2+ relicensing are listed below. The list might include ACKs from people not holding copyright on any parts of the reused code, but it's better to err on the side of caution and include them.

2013-10-11Use qemu-project.org domain nameStefan Hajnoczi2-2/+2
qemu.org is held by a third-party and no core community contributor has access to the DNS configuration. This leaves the website exposed to outages due to DNS issues or IP address changes. For example, if the web server IP address needs to change we cannot guarantee qemu.org will point to it! The newer qemu-project.org domain name is owned by Anthony Liguori <anthony@codemonkey.ws>. You can confirm this by querying the whois information. Also note that the #qemu IRC channel topic already references qemu-project.org. Short of having a dedicated legal entity to hold the domain name on behalf of the community, qemu-project.org seems like the safest bet. Let's replace references to qemu.org with qemu-project.org. Note that git-submodule(1) does not detect URL changes. The following commands clear out and re-initialize all submodules to ensure you are using the latest URLs: $ git submodule deinit . # you'll be warned if you have local changes $ rm -rf .git/modules # also clear cached .git/ directories $ git submodule update --init Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-id: 1381495958-8306-1-git-send-email-stefanha@redhat.com Signed-off-by: Anthony Liguori <aliguori@amazon.com>
