2012-08-22xen-all.c: fix multiply issue for int and uint typesDongxiao Xu
If the two multiply operands are int and uint types separately, the int type will be transformed to uint firstly, which is not the intent in our code piece. The fix is to add (int64_t) transform for the uint type before the multiply. Signed-off-by: Dongxiao Xu <dongxiao.xu@intel.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
2012-08-22Fix invalidate if memory requested was not bucket alignedFrediano Ziglio
When memory is mapped in qemu_map_cache with lock != 0 a reverse mapping is created pointing to the virtual address of location requested. The cached mapped entry is saved in last_address_vaddr with the memory location of the base virtual address (without bucket offset). However when this entry is invalidated the virtual address saved in the reverse mapping is used. This cause that the mapping is freed but the last_address_vaddr is not reset.

2012-08-21eventfd: making it thread safeAlexey Kardashevskiy
QEMU uses IO handlers to run select() in the main loop. The handlers list is managed by qemu_set_fd_handler() helper which works fine when called from the main thread as it is called when select() is not waiting. However IO handlers list can be changed in the thread other than the main one doing os_host_main_loop_wait(), for example, as a result of a hypercall which changes PCI config space (VFIO on POWER is the case) and enables/disabled MSI/MSIX which closes/creates eventfd handles. As the main loop should be waiting on the newly created eventfds, it has to be restarted. The patch adds the qemu_notify_event() call to interrupt select() to make main_loop() restart select() with the updated IO handlers list.

2012-08-20iscsi: fix races between task completion and abortPaolo Bonzini
This patch fixes two main issues with block/iscsi.c: 1) iscsi_task_mgmt_abort_task_async calls iscsi_scsi_task_cancel which was also directly called in iscsi_aio_cancel 2) a race between task completion and task abortion could happen cause the scsi_free_scsi_task were done before iscsi_schedule_bh has finished. To fix this, all the freeing of IscsiTasks and releasing of the AIOCBs is centralized in iscsi_bh_cb, independent of whether the SCSI command has completed or was cancelled. 3) iscsi_aio_cancel was not synchronously waiting for the end of the command.

The commit returned immediately from iscsi_aio_cancel, risking corruption in case the following happens: guest qemu target ========================================================================= send write 1 --------> send write 1 --------> cancel write 1 ------> cancel write 1 ------> <------------------ cancellation processed send write 2 --------> send write 2 --------> <---------------- completed write 2 <------------------ completed write 2 <---------------- completed write 1 <---------------- cancellation not done Here, the guest would see write 2 superseding write 1, when in fact the outcome could have been the opposite.

2012-08-17virtio-blk: hide VIRTIO_BLK_F_CONFIG_WCE from old machine typesStefan Hajnoczi
QEMU has a policy of keeping a stable guest device ABI. When new guest device features are introduced they must not change hardware info seen by existing guests. This is important because operating systems or applications may "fingerprint" the hardware and refuse to run when the hardware changes. To always get the latest guest device ABI, run with x86 machine type "pc". This patch hides the new VIRTIO_BLK_F_CONFIG_WCE virtio feature bit from existing machine types. Only pc-1.2 and later will expose this feature by default. For more info on the VIRTIO_BLK_F_CONFIG_WCE feature bit, see: commit 13e3dce068773c971ff2f19d986378c55897c4a3 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Thu Aug 9 16:07:19 2012 +0200 virtio-blk: support VIRTIO_BLK_F_CONFIG_WCE Also rename VIRTIO_BLK_F_WCACHE to VIRTIO_BLK_F_WCE for consistency with the spec.

2012-08-16Allow QEMUMachine to override reset sequencingDavid Gibson
qemu_system_reset() function always performs the same basic actions on all machines. This includes running all the reset handler hooks, however the order in which these will run is not always easily predictable. This patch splits the core of qemu_system_reset() - the invocation of the reset handlers - out into a new qemu_devices_reset() function. qemu_system_reset() will usually call qemu_devices_reset(), but that can be now overriden by a new reset method in the QEMUMachine structure. Individual machines can use this reset method, if necessary, to perform any extra, machine specific initializations which have to occur before or after the bulk of the reset handlers. It's expected that the method will call qemu_devices_reset() at some point, but if the machine has really strange ordering requirements between devices resets it could even override that with it's own reset sequence (with great care, obviously). For a specific example of when this might be needed: a number of machines (but not PC) load images specified with -kernel or -initrd directly into the machine RAM before booting the guest. This mostly works at the moment, but to make this actually safe requires that this load occurs after peripheral devices are reset - otherwise they could have active DMAs in progress which would clobber the in memory images. Some machines (notably pseries) also have other entry conditions which need to be set up as the last thing before executing in guest space - some of this could be considered "emulated firmware" in the sense that the actions of the firmware are emulated directly by qemu rather than by executing a firmware image within the guest. When the platform's firmware to OS interface is sufficiently well specified, this saves time both in implementing the "firmware" and executing it. aliguori: don't unconditionally dereference current_machine Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This patch addresses this by adding a USB interface when requested, and automatically adding a USB keyboard and mouse when VGA is enabled. This is a stop gap measure to get usable graphics mode on pseries while waiting for Li Zhang's rework of USB options to go in after 1.2.

2012-08-16Support using a different compiler for Objective-C filesPeter Maydell
MacOSX 10.8 ("Mountain Lion") requires us to compile our one Objective-C source file with clang even if the rest of QEMU requires a real gcc, because the system headers we use make use of Apple's "Blocks" extension to C/ObjC, and mainline gcc doesn't support that. Since we only need to use a true gcc for the parts of QEMU that use the fixed-register env variable, we can simply use clang to build the ObjC file: it will link to the gcc-built objects with no problems. Add the necessary support for an OBJCC variable in the makefile and configure machinery; we default to clang if we have it, otherwise whatever CC is (since gcc might be the Apple gcc which does support Blocks).

2012-08-16json-parser: don't replicate tokens at each level of recursionMichael Roth
Currently, when parsing a stream of tokens we make a copy of the token list at the beginning of each level of recursion so that we do not modify the original list in cases where we need to fall back to an earlier state. In the worst case, we will only read 1 or 2 tokens off the list before recursing again, which means an upper bound of roughly N^2 token allocations. For a "reasonably" sized QMP request (in this a QMP representation of cirrus_vga's device state, generated via QIDL, being passed in via qom-set), this caused my 16GB's of memory to be exhausted before any noticeable progress was made by the parser. This patch works around the issue by using single copy of the token list in the form of an indexable array so that we can save/restore state by manipulating indices. A subsequent commit adds a "large_dict" test case which exhibits the same behavior as above. With this patch applied the test case successfully completes in under a second.

2012-08-15win32: provide separate macros for weak decls and definitionsAnthony Liguori
mingw32 seems to want the declaration to also carry the weak attribute. Strangely, gcc on Linux absolutely does not want the declaration to be marked as weak. This may not be the right fix, but it seems to do the trick. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2012-08-15openpic: Added BRR1 registerBharat Bhushan
Linux mpic driver uses (changes may be in pipeline to get upstreamed soon) BRR1. This patch adds the support to emulate readonly FSL BRR1 register. Currently QEMU does not fully emulate any version on MPIC, so the MPIC Major number and Minor number are set to 0.
