2013-06-14main: use TARGET_ARCH only for the target-specific #definePaolo Bonzini

2013-06-14build: do not use TARGET_ARCHPaolo Bonzini
TARGET_ARCH is generally wrong to use, there are better variables provided in config-target.mak. The right one is usually TARGET_NAME (previously TARGET_ARCH2), but for bsd-user we can also use TARGET_ABI_DIR for consistency with linux-user.

2013-06-04block: add block driver read only whitelistFam Zheng
We may want to include a driver in the whitelist for read only tasks such as diagnosing or exporting guest data (with libguestfs as a good example). This patch introduces a readonly whitelist option, and for backward compatibility, the old configure option --block-drv-whitelist is now an alias to rw whitelist. Drivers in readonly list is only permitted to open file readonly, and returns -ENOTSUP for RW opening. E.g. To include vmdk readonly, and others read+write: ./configure --target-list=x86_64-softmmu \ --block-drv-rw-whitelist=qcow2,raw,file,qed \ --block-drv-ro-whitelist=vmdk Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2013-05-30qapi: pad GenericList value fields to 64 bitsMichael Roth
With the introduction of native list types, we now have types such as int64List where the 'value' field is not a pointer, but the actual 64-bit value. On 32-bit architectures, this can lead to situations where 'next' field offset in GenericList does not correspond to the 'next' field in the types that we cast to GenericList when using the visit_next_list() interface, causing issues when we attempt to traverse linked list structures of these types. To fix this, pad the 'value' field of GenericList and other schema-defined/native *List types out to 64-bits. This is less memory-efficient for 32-bit architectures, but allows us to continue to rely on list-handling interfaces that target GenericList to simply visitor implementations. In the future we can improve efficiency by defaulting to using native C array backends to handle list of non-pointer types, which would be more memory efficient in itself and allow us to roll back this change.

2013-05-23qapi: qapi-visit.py, fix list handling for union typesMichael Roth
Currently we assume non-list types when generating visitor routines for union types. This is broken, since values like ['Type'] need to mapped to 'TypeList'. We already have a type_name() function to handle this that we use for generating struct visitors, so use that here as well.

2013-05-03trace: Add ftrace tracing backendEiichi Tsukata
This patch adds a ftrace tracing backend which sends trace event to ftrace marker file. You can effectively compare qemu trace data and kernel(especially, kvm.ko when using KVM) trace data. The ftrace backend is restricted to Linux only. To try out the ftrace backend: $ ./configure --trace-backend=ftrace $ make if you use KVM, enable kvm events in ftrace: # sudo echo 1 > /sys/kernel/debug/tracing/events/kvm/enable After running qemu by root user, you can get the trace: # cat /sys/kernel/debug/tracing/trace Signed-off-by: Eiichi Tsukata <eiichi.tsukata.xh@hitachi.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
