2014-03-13Fix vga_interface_type for command line argument '-device VGA'Mark Wu1-1/+1
Some machine (like pseries) initialization code determines if it has graphics according to vga_interface_type. In the original code, vga_interface_type is evaluated to VGA_NONE even if a VGA is added via '-device VGA'. It causes the machine not aware of the graphics device configured. Add a new VGA device type to indicate that it has a VGA device, which will be initialized in QOM device initialization.

2014-03-13iothread: add I/O thread objectStefan Hajnoczi1-0/+30
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>

2014-03-05KVM: Split QEMUMachine typedef into separate headerAlexander Graf3-0/+18
Older gcc versions (such as the one in SLES11) get confused when you declare a typedef on the same struct twice. To work around that limitation, let's extract the QEMUMachine typedef into a separate header file that is guarded by preprocessor duplicate include checks. This fixes the following type of compile errors for me: In file included from vl.c:125: include/hw/xen/xen.h:39: error: redefinition of typedef "QEMUMachine" include/sysemu/kvm.h:155: error: previous declaration of "QEMUMachine" was here Signed-off-by: Alexander Graf <agraf@suse.de>

Since proprietary FCode ROMs use a resolution of 1152x900, slightly relax the validation rules to allow both displays to be initiated at the higher resolution used by these ROMs upon request (OpenBIOS FCode ROMs default to the normal QEMU sun4m default resolution of 1024x768).

2013-12-10qtest: split configuration of qtest accelerator and chardevPaolo Bonzini1-20/+5
qtest uses the icount infrastructure to implement a test-driven vm_clock. This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

2013-09-28smbios: Make multiple -smbios type= accumulate sanelyMarkus Armbruster1-0/+1
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with value VAL to fw_cfg for each unique NAME. If NAME occurs multiple times, the last one's VAL is used (before the QemuOpts conversion, the first one was used). Multiple -smbios can add multiple fields with the same (T, NAME). SeaBIOS reads all of them from fw_cfg, but uses only the first field (T, NAME). The others are ignored. "First one wins, subsequent ones get ignored silently" isn't nice. We commonly let the last option win. Useful, because it lets you -readconfig first, then selectively override with command line options. Clean up -smbios to work the common way. Accumulate the settings, with later ones overwriting earlier ones. Put the result into fw_cfg (no more useless duplicates). Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by side effect.

2013-09-25qemu: Adjust qemu wakeupLiu, Jinsong1-1/+3
Currently Xen hvm s3 has a bug coming from the difference between qemu-traditioanl and qemu-xen. For qemu-traditional, the way to resume from hvm s3 is via 'xl trigger' command. However, for qemu-xen, the way to resume from hvm s3 inherited from standard qemu, i.e. via QMP, and it doesn't work under Xen. The root cause is, for qemu-xen, 'xl trigger' command didn't reset devices, while QMP didn't unpause hvm domain though they did qemu system reset. We have two qemu patches and one xl patch to fix Xen hvm s3 bug. This patch is the qemu patch 1. It adjusts qemu wakeup so that Xen s3 resume logic (which will be implemented at qemu patch 2) will be notified after qemu system reset.

On PPC64 systems MSI Messages are translated to system IRQ in a PCI host bridge. This is already supported for emulated MSI/MSIX but not for irqfd where the current QEMU allocates IRQ numbers from irqchip and maps MSIMessages to IRQ in the host kernel. This adds a new direct mapping flag which tells the kvm_irqchip_add_msi_route() function that a new VIRQ should not be allocated, instead the value from MSIMessage::data should be used. It is up to the platform code to make sure that this contains a valid IRQ number as sPAPR does in spapr_pci.c.

Move this call up into the generic cpu_dump_state() function so that other KVM targets (namely MIPS) can take advantage of it.

2013-08-09kvm: add KVM_IRQFD_FLAG_RESAMPLE supportVincenzo Maffione1-1/+2
Added an EventNotifier* parameter to kvm-all.c:kvm_irqchip_add_irqfd_notifier(), in order to give KVM another eventfd to be used as "resamplefd". See the documentation in the linux kernel sources in Documentation/virtual/kvm/api.txt (section 4.75) for more details. When the added parameter is passed NULL, the behaviour of the function is unchanged with respect to the previous versions.

2013-08-08dump: rebase from host-private RAMBlock offsets to guest-physical addressesLaszlo Ersek2-3/+8
RAMBlock.offset --> GuestPhysBlock.target_start RAMBlock.offset + RAMBlock.length --> GuestPhysBlock.target_end RAMBlock.length --> GuestPhysBlock.target_end - GuestPhysBlock.target_start "GuestPhysBlock.host_addr" is only used when writing the dump contents. This patch enables "crash" to work with the vmcore by rebasing the vmcore from the left side of the following diagram to the right side: host-private offset relative to ram_addr RAMBlock guest-visible paddrs 0 +-------------------+.....+-------------------+ 0 | ^ | | ^ | | 640 KB | | 640 KB | | v | | v | 0x0000a0000 +-------------------+.....+-------------------+ 0x0000a0000 | ^ | |XXXXXXXXXXXXXXXXXXX| | 384 KB | |XXXXXXXXXXXXXXXXXXX| | v | |XXXXXXXXXXXXXXXXXXX| 0x000100000 +-------------------+.....+-------------------+ 0x000100000 | ^ | | ^ | | 3583 MB | | 3583 MB | | v | | v | 0x0e0000000 +-------------------+.....+-------------------+ 0x0e0000000 | ^ |. |XXXXXXXXXXXXXXXXXXX| | above_4g_mem_size | . |XXXX PCI hole XXXXX| | v | . |XXXX XXXXX| ram_size +-------------------+ . |XXXX 512 MB XXXXX| . .|XXXXXXXXXXXXXXXXXXX| . +-------------------+ 0x100000000 . | ^ | . | above_4g_mem_size | .| v | +-------------------+ ram_size + 512 MB Related RHBZ: https://bugzilla.redhat.com/show_bug.cgi?id=981582 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
2013-08-08dump: populate guest_phys_blocksLaszlo Ersek1-0/+1
While the machine is paused, in guest_phys_blocks_append() we register a one-shot MemoryListener, solely for the initial collection of the valid guest-physical memory ranges that happens at listener registration time. For each range that is reported to guest_phys_blocks_region_add(), we attempt to merge the range with the preceding one. Ranges can only be joined if they are contiguous in both guest-physical address space, and contiguous in host virtual address space. The "maximal" ranges that remain in the end constitute the guest-physical memory map that the dump will be based on.

2013-08-08dump: introduce GuestPhysBlockListLaszlo Ersek1-0/+22
The vmcore must use physical addresses that are visible to the guest, not addresses that point into linear RAMBlocks. As first step, introduce the list type into which we'll collect the physical mappings in effect at the time of the dump.

2013-07-30chardev: fix CHR_EVENT_OPENED events for mux chardevsMichael Roth1-0/+1
As of bd5c51ee6c4f1c79cae5ad2516d711a27b4ea8ec, chardevs no longer use bottom-halves to issue CHR_EVENT_OPENED events. To maintain past semantics, we instead defer the CHR_EVENT_OPENED events toward the end of chardev initialization. For muxes, this isn't good enough, since a range of FEs must be able to attach to the mux prior to any CHR_EVENT_OPENED being issued, else each FE will immediately print it's initial output (prompts, banners, etc.) just prior to us switching to the next FE as part of initialization. The is new and confusing behavior for users, as they'll see output for things like the HMP monitor, even though their the current mux focus may be a guest serial port with potentially no output. We fix this by further deferring CHR_EVENT_OPENED events for FEs associated with muxes until after machine init by flagging mux chardevs with 'explicit_be_open', which suppresses emission of CHR_EVENT_OPENED events until we explicitly set the mux as opened later. Currently, we must defer till after machine init since we potentially associate FEs with muxes as part of realize (for instance, serial_isa_realizefn).

2013-07-30spice: fix display initializationGerd Hoffmann1-1/+0
Spice has two display interface implementations: One integrated into the qxl graphics card, and one generic which can operate with every qemu-emulated graphics card. The generic one is activated in case spice is used without qxl. The logic for that only caught the "-vga qxl" case, "-device qxl-vga" goes unnoticed. Fix that by adding a check in the spice interface registration so we'll notice the qxl card no matter how it is created. https://bugzilla.redhat.com/show_bug.cgi?id=981094 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
