* qtest: split configuration of qtest accelerator and chardevPaolo Bonzini2013-12-101-20/+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.

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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * | spice: fix display initializationGerd Hoffmann2013-07-301-1/+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>
* | | chardev: fix CHR_EVENT_OPENED events for mux chardevsMichael Roth2013-07-301-0/+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).

* device_tree: Add qemu_devtree_setprop_sized_cells() utility functionsPeter Maydell2013-07-191-0/+59
| | | | | | | | | | | | | | | | | | | We already have a qemu_devtree_setprop_cells() which sets a dtb property to an array of cells whose values are specified by varargs. However for the fairly common case of setting a property to a list of addresses or of address,size pairs the number of cells used by each element in the list depends on the parent's #address-cells and #size-cells properties. To make this easier we provide an analogous qemu_devtree_setprop_sized_cells() macro which allows the number of cells used by each element to be specified. This is implemented using an underlying qemu_devtree_setprop_sized_cells_from_array() function which takes the values and sizes as an array; this may also be directly useful for cases where the cell contents are constructed programmatically.

* KVM: PIC: Only commit irq routing when necessaryAlexander Graf2013-07-011-0/+1
| | | | | | | | | | | | | The current logic updates KVM's view of our interrupt map every time we change it. While this is nice and bullet proof, it slows things down badly for me. QEMU spends about 3 seconds on every start telling KVM what news it has on its routing maps. Instead, let's just synchronize the whole irq routing map as a whole when we're done constructing it. For things that change during runtime, we can still update the routing table on demand. Signed-off-by: Alexander Graf <agraf@suse.de>
