2017-02-16vl: Move the cpu_synchronize_all_post_init() after generic devices ↵Dou Liyang
initialization At the Qemu initialization, we call the cpu_synchronize_all_post_init() to synchronize All CPU states to KVM in the ./vl.c::main(). Currently, it is called before we initialize the CPUs, which is created by "-device" command and parsed by generic devices initialization, So, these CPUs may be ignored to synchronize. The patch moves the cpu_synchronize_all_post_init func after generic devices initialization to make sure that all the CPUs can be included.

2017-01-31trace: switch to modular code generation for sub-directoriesDaniel P. Berrange
Introduce rules in the top level Makefile that are able to generate trace.[ch] files in every subdirectory which has a trace-events file. The top level directory is handled specially, so instead of creating trace.h, it creates trace-root.h. This allows sub-directories to include the top level trace-root.h file, without ambiguity wrt to the trace.g file in the current sub-dir.

2017-01-27chardev: qom-ifyMarc-André Lureau
Turn Chardev into Object. qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It will call qemu_char_open() to open/intialize the chardev with the ChardevCommon *backend settings. The CharDriver::create() callback is turned into a ChardevClass::open() which is called from the newly introduced qemu_chardev_open(). "chardev-gdb" and "chardev-hci" are internal chardev and aren't creatable directly with -chardev. Use a new internal flag to disable them. We may want to use TYPE_USER_CREATABLE interface instead, or perhaps allow -chardev usage. Although in general we keep typename and macros private, unless the type is being used by some other file, in this patch, all types and common helper macros for qemu-char.c are in char.h. This is to help transition now (some types must be declared early, while some aren't shared) and when splitting in several units. This is to be improved later.

2017-01-23vl: Ensure the numa_post_machine_init func in the appropriate locationDou Liyang
In the numa_post_machine_init(), we use CPU_FOREACH macro to set all CPUs' namu_node. So, we should make sure that we call it after Qemu has already initialied all the CPUs. As we all know, the CPUs can be created by "-smp"(pc_new_cpu) or "-device"(qdev_device_add) command. But, before the device init, Qemu execute the numa_post_machine_init earlier.

2016-11-09vl.c: move pidfile creation up the lineMichael Tokarev
With current code, pid file is open after various sockets, chardevs, fsdevs and the like. This causes interesting effects, for example when monitor is a unix-socket, and another qemu instance is already running, new qemu first "damages" the socket and next complain that it can't acquire the pid file and exits, making running qemu unreachable. Move pid file creation earlier, right after the call to os_daemonize(), where we know our process id (pid).

2016-10-27fdc: Move qdev properties to FloppyDriveKevin Wolf
This makes the FloppyDrive qdev object actually useful: Now that it has all properties that don't belong to the controller, you can actually use '-device floppy' and get a working result. Command line semantics is consistent with CD-ROM drives: By default you get a single empty floppy drive. You can override it with -drive and using the same index, but if you use -drive to add a floppy to a different index, you get both of them. However, as soon as you use any '-device floppy', even to a different slot, the default drive is disabled. Using '-device floppy' without specifying the unit will choose the first free slot on the controller.

2016-10-24cpu: Support a target CPU having a variable page sizePeter Maydell
Support target CPUs having a page size which isn't knownn at compile time. To use this, the CPU implementation should: * define TARGET_PAGE_BITS_VARY * not define TARGET_PAGE_BITS * define TARGET_PAGE_BITS_MIN to the smallest value it might possibly want for TARGET_PAGE_BITS * call set_preferred_target_page_bits() in its realize function to indicate the actual preferred target page size for the CPU (and report any error from it) In CONFIG_USER_ONLY, the CPU implementation should continue to define TARGET_PAGE_BITS appropriately for the guest OS page size. Machines which want to take advantage of having the page size something larger than TARGET_PAGE_BITS_MIN must set the MachineClass minimum_page_bits field to a value which they guarantee will be no greater than the preferred page size for any CPU they create. Note that changing the target page size by setting minimum_page_bits is a migration compatibility break for that machine. For debugging purposes, attempts to use TARGET_PAGE_SIZE before it has been finally confirmed will assert.

2016-10-07block: Add bdrv_runtime_opts to query-command-line-optionsKevin Wolf
Recently we moved a few options from QemuOptsLists in blockdev.c to bdrv_runtime_opts in block.c in order to make them accissble using blockdev-add. However, this has the side effect that these options are missing from query-command-line-options now, and libvirt consequently disables the corresponding feature. This problem was reported as a regression for the 'discard' option, introduced in commit 818584a4. However, it is more general than that. Fix it by adding bdrv_runtime_opts to the list of QemuOptsLists that are returned in query-command-line-options. For the future, libvirt is advised to use QMP schema introspection for block device options.

2016-09-23vl: Switch qemu_uuid to QemuUUIDFam Zheng
Update all qemu_uuid users as well, especially get rid of the duplicated low level g_strdup_printf, sscanf and snprintf calls with QEMU UUID API. Since qemu_uuid_parse is quite tangled with qemu_uuid, its switching to QemuUUID is done here too to keep everything in sync and avoid code churn.

2016-09-23util: Add UUID APIFam Zheng
A number of different places across the code base use CONFIG_UUID. Some of them are soft dependency, some are not built if libuuid is not available, some come with dummy fallback, some throws runtime error. It is hard to maintain, and hard to reason for users. Since UUID is a simple standard with only a small number of operations, it is cleaner to have a central support in libqemuutil. This patch adds qemu_uuid_* functions that all uuid users in the code base can rely on. Except for qemu_uuid_generate which is new code, all other functions are just copy from existing fallbacks from other files. Note that qemu_uuid_parse is moved without updating the function signature to use QemuUUID, to keep this patch simple.

2016-09-13vl: remove unnecessary duplicate call to tpm_cleanupPaolo Bonzini
tpm_cleanup is called from main() and also registered with atexit from tpm_init. The function only visits the tpm_backends linked list, and the atexit registration happens right after tpm_init fills in the list from -tpmdev options. Therefore, the direct call is unnecessary. Remove it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
