2014-10-14qemu-file: Move stdio implementation to qemu-file-stdio.cEduardo Habkost
Separate the QEMUFile interface from the stdio-specific implementation, to reduce dependencies from code using QEMUFile. The code that is being moved is similar to the one that was on savevm.c before it was moved in commit 093c455a8c6d8f715eabd8c8d346f08f17d686ec, except for some changes done by Markus, Juan, and myself. So, I am using the copyright and license header from savevm.c, but CCing Juan and Markus so they can review the copyright/license header.

Generates file "trace/generated-helpers.c" with TCG helper definitions to trace events in guest code at execution time. The helpers ('helper_trace_${event}_exec_proxy') cast the TCG-compatible native argument types to their original types (as defined in "trace-events") and call the tracing routine ('trace_${event}_exec').

2014-06-23qapi script: add event supportWenchao Xia
qapi-event.py will parse the schema and generate qapi-event.c, then the API in qapi-event.c can be used to handle events in qemu code. All API have prefix "qapi_event". The script mainly includes two parts: generate API for each event define, generate an enum type for all defined events. Since in some cases the real emit behavior may change, for example, qemu-img would not send a event, a callback layer is used to control the behavior. As a result, the stubs at compile time can be saved, the binding of block layer code and monitor code will become looser.

2014-05-09libcacard: remove libcacard-specific CFLAGS and LIBS from global varsMichael Tokarev
Currently all what's needed for single file libcacard/vcard_emul_nss.c (libnss cflags) and hw/usb/ccid-card-emulated.c (libcacard includes) together with the libs is added to global QEMU_CFLAGS and libs_softmmu. Use the cflags only where really used (for two mentioned files), and libs only where needed. While at it, rename variables to better reflect reality: libcacard_* is really nss_*. This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs (ditto for _cflags). But in order to fix it, some more preparations should be made first. So add a FIXME comment.

2014-03-13iothread: add I/O thread objectStefan Hajnoczi
This is a stand-in for Michael Roth's QContext. I expect this to be replaced once QContext is completed. The IOThread object is an AioContext event loop thread. This patch adds the concept of multiple event loop threads, allowing users to define them. When SMP guests run on SMP hosts it makes sense to instantiate multiple IOThreads. This spreads event loop processing across multiple cores. Note that additional patches are required to actually bind a device to an IOThread. [Andreas Färber <afaerber@suse.de> pointed out that the embedded parent object instance should be called "parent_obj" and have a newline afterwards. This patch has been changed to reflect this. -- Stefan] Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2014-02-20rules.mak: fix $(obj) to a real relative pathFam Zheng
Makefile.target includes rule.mak and unnested common-obj-y, then prefix them with '../', this will ignore object specific QEMU_CFLAGS in subdir Makefile.objs: $(obj)/curl.o: QEMU_CFLAGS += $(CURL_CFLAGS) Because $(obj) here is './block', instead of '../block'. This doesn't hurt compiling because we basically build all .o from top Makefile, before entering Makefile.target, but it will affact arriving per-object libs support. The starting point of $(obj) is passed in as argument of unnest-vars, as well as nested variables, so that different Makefiles can pass in a right value.

2013-09-09qemu-ga: Add Windows VSS provider and requester as DLLTomoki Sekiyama
Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).

2013-05-06target-i386: Add "feature-words" property to X86CPUEduardo Habkost
This property will be useful for libvirt, as libvirt already has logic based on low-level feature bits (not feature names), so it will be really easy to convert the current libvirt logic to something using the "feature-words" property. The property will have two main use cases: - Checking host capabilities, by checking the features of the "host" CPU model - Checking which features are enabled on each CPU model Example output: $ ./QMP/qmp --path=/tmp/m \ qom-get --path=/machine/icc-bridge/icc/child[0] \ --property=feature-words item[0].cpuid-register: EDX item[0].cpuid-input-eax: 2147483658 item[0].features: 0 item[1].cpuid-register: EAX item[1].cpuid-input-eax: 1073741825 item[1].features: 0 item[2].cpuid-register: EDX item[2].cpuid-input-eax: 3221225473 item[2].features: 0 item[3].cpuid-register: ECX item[3].cpuid-input-eax: 2147483649 item[3].features: 101 item[4].cpuid-register: EDX item[4].cpuid-input-eax: 2147483649 item[4].features: 563346425 item[5].cpuid-register: EBX item[5].cpuid-input-eax: 7 item[5].features: 0 item[5].cpuid-input-ecx: 0 item[6].cpuid-register: ECX item[6].cpuid-input-eax: 1 item[6].features: 2155880449 item[7].cpuid-register: EDX item[7].cpuid-input-eax: 1 item[7].features: 126614521 Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-04-15tpm: reorganize headers and split hardware partPaolo Bonzini
The TPM subsystem does not have a full front-end/back-end separation. The sole available backend, tpm_passthrough, depends on the data structures of the sole available frontend, tpm_tis. However, we can at least try to split the user interface (tpm.c) from the implementation (hw/tpm). The patches makes tpm.c not include tpm_int.h, which is shared between tpm_tis.c and tpm_passthrough.c; instead it moves more stuff to tpm_backend.h.

2013-04-08configure: Don't fall back to gthread coroutine backendPeter Maydell
The gthread coroutine backend is broken and does not produce a working QEMU; it is only useful for some very limited debugging situations. Clean up the backend selection logic in configure so that it now runs "if on windows use windows; else prefer ucontext; else sigaltstack". To do this we refactor the configure code to separate out "test whether we have a working ucontext", "pick a default if user didn't specify" and "validate that user didn't specify something invalid", rather than having all three of these run together. We also simplify the Makefile logic so it just links in the backend the configure script selects.

2013-03-12Support for TPM command line optionsStefan Berger
This patch adds support for TPM command line options. The command line options supported here are ./qemu-... -tpmdev passthrough,path=<path to TPM device>,id=<id> -device tpm-tis,tpmdev=<id>,id=<other id> and ./qemu-... -tpmdev help where the latter works similar to -soundhw help and shows a list of available TPM backends (for example 'passthrough'). Using the type parameter, the backend is chosen, i.e., 'passthrough' for the passthrough driver. The interpretation of the other parameters along with determining whether enough parameters were provided is pushed into the backend driver, which needs to implement the interface function 'create' and return a TPMDriverOpts structure if the VM can be started or 'NULL' if not enough or bad parameters were provided. Monitor support for 'info tpm' has been added. It for example prints the following: (qemu) info tpm TPM devices: tpm0: model=tpm-tis \ tpm0: type=passthrough,path=/dev/tpm0,cancel-path=/sys/devices/pnp0/00:09/cancel Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Reviewed-by: Corey Bryant <coreyb@linux.vnet.ibm.com> Reviewed-by: Joel Schopp <jschopp@linux.vnet.ibm.com> Message-id: 1361987275-26289-2-git-send-email-stefanb@linux.vnet.ibm.com Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
