2017-03-03vl: disable default cdrom when using explicitely scsi-hdHervé Poussineau1-0/+1
In commit af6bf1328ef90fae617857c02697e0174b84d596 (May 2011), ide-hd, ide-cd and scsi-cd have been added to disable default cdrom, "or else you can't put one on secondary master without -nodefaults". Make it the same for scsi-hd, so you can put one on scsi-id 2 without using -nodefaults. scsi-hd has probably been forgotten, as it has been added in the preceding commit (b443ae67130d32ad06b06fc9aa6d04d05ccd93ce). Affected users are the ones using a machine with SCSI devices and start QEMU with -device scsi-hd but without -device scsi-cd or -cdrom In that case, the default cdrom device will disappear instead of being empty.

2017-02-21hw: Deprecate -drive if=scsi with non-onboard HBAsMarkus Armbruster1-1/+7
Block backends defined with "-drive if=T" with T other than "none" are meant to be picked up by machine initialization code: a suitable frontend gets created and wired up automatically. Drives defined with if=scsi are also picked up by SCSI HBAs added with -device, unlike other interface types. Deprecate this usage, as follows. Create the frontends for onboard HBAs in machine initialization code, exactly like we do for if=ide and other interface types. Change scsi_legacy_handle_cmdline() to create a frontend only when it's still missing, and warn that this usage is deprecated.

2017-02-21hw/scsi: Concentrate -drive if=scsi auto-create in one placeMarkus Armbruster1-0/+4
The logic to create frontends for -drive if=scsi is in SCSI HBAs. For all other interface types, it's in machine initialization code. A few machine types create the SCSI HBAs necessary for that. That's also not done for other interface types. I'm going to deprecate these SCSI eccentricities. In preparation for that, create the frontends in main() instead of the SCSI HBAs, by calling new function scsi_legacy_handle_cmdline() there. Note that not all SCSI HBAs create frontends. Take care not to change that. Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <1487161136-9018-2-git-send-email-armbru@redhat.com> Acked-By: Paolo Bonzini <pbonzini@redhat.com>

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().

2017-01-27chardev: qom-ifyMarc-André Lureau1-0/+2
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 Liyang1-2/+3
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. It makes the mapping of NUMA nodes and CPUs incorrect. The patch move the numa_post_machine_init func in the appropriate location.

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 Maydell1-0/+10
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.

2016-10-17hw/arm/boot: allow using a command line specified dtb without a kernelMichael Olbrich1-5/+0
When kernel and device tree are specified in the QEMU commandline, then this device tree may be modified e.g. to add virtio_mmio devices. With a bootloader e.g. on a flash device these extra devices are not available. With this change, the device tree can be specified at the QEMU commandline. The modified device tree made available to the bootloader with the same mechanism already supported by device trees fully generated by QEMU.

2016-10-17machine: Fix replacement of '_' by '-' in machine property namesMarkus Armbruster1-5/+4
machine_set_property() replaces '_' by '-' in the property name. Except it fails to replace an initial '_'. Screwed up in commit b0ddb8b. Reproducer: "-M pc,__foo_bar=true" produces "Property '._-foo-bar' not found". Error messages using a mangled name rather than the name the user actually wrote is user-hostile, but that's a different topic.

2016-10-12trace: provide mechanism for registering trace eventsDaniel P. Berrange1-0/+2
Remove the notion of there being a single global array of trace events, by introducing a method for registering groups of events. The module_call_init() needs to be invoked at the start of any program that wants to make use of the trace support. Currently this covers system emulators qemu-nbd, qemu-img and qemu-io. [Squashed the following fix from Daniel P. Berrange <berrange@redhat.com>: linux-user/bsd-user: initialize trace events subsystem The bsd-user/linux-user programs make use of the CPU emulation code and this now requires that the trace events subsystem is enabled, otherwise it'll crash trying to allocate an empty trace events bitmap for the CPU object. --Stefan] Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Lluís Vilanova <vilanova@ac.upc.edu> Signed-off-by: Daniel P.

2016-10-07block: Add bdrv_runtime_opts to query-command-line-optionsKevin Wolf1-0/+1
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.
