* stefanha/tracing: trace: Remove "info trace" from documents trace: document '-' syntax for disabling events trace: allow disabling events in events file Avoid all systemtap reserved words Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-11-16Avoid all systemtap reserved wordsDaniel P. Berrange
Over time various systemtap reserved words have been blacklisted in the trace backend generator. The list is not complete though, so there is continued risk of problems in the future. Preempt such problems by specifying the full list of systemtap keywords listed in its parser as identified here: http://sourceware.org/ml/systemtap/2012-q4/msg00157.html Signed-off-by: Daniel P.

2012-10-30update-linux-headers.sh: Handle new kernel uapi/ directoriesPeter Maydell
Recent kernels have moved to keeping the userspace headers in uapi/ subdirectories. This breaks the detection of whether an architecture has KVM support in the kernel because kvm.h has moved in the kernel source tree. Update the check to support both the old and new locations.

2012-10-29s390/kvm_stat: correct sys_perf_event_open syscall numberHeinz Graalfs
Correct sys_perf_event_open syscall number for s390 architecture - the hardcoded syscall number 298 is for x86 but should be different for other architectures. In case we figure out via /proc/cpuinfo that we are running on s390 the appropriate syscall number is used from map syscall_numbers; other architectures can extend this.

2012-09-11update-linux-headers.sh: Don't hard code list of architecturesPeter Maydell
Rather than hardcoding the list of architectures in the kernel header update script, just import headers for every architecture which supports KVM (with a blacklist exception for ia64 which has KVM headers but is dead). This reduces the number of QEMU files which need to be updated to add support for a new KVM architecture.

2012-09-05qapi: generate list struct and visit_list for enumAmos Kong
Currently, if we define an 'enum' and use it in one command's data, list struct for enum could not be generated, but it's used in qmp function. For example: KeyCodesList could not be generated. >>> qapi-schema.json: { 'enum': 'KeyCodes', 'data': [ 'shift', 'alt' ... ] } { 'command': 'sendkey', 'data': { 'keys': ['KeyCodes'], '*hold-time': 'int' } } >>> qmp-command.h: void qmp_sendkey(KeyCodesList * keys, bool has_hold_time, int64_t hold_time, Error **errp); This patch lets qapi generate list struct and visit_list for enum.
