| * qdev: add command line option to set global defaults for properties.Gerd Hoffmann2009-12-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds infrastructure and command line option for setting global defaults for device properties, i.e. you can for example use -global virtio-blk-pci.vectors=0 to turn off msi by default for all virtio block devices. The config file syntax is: [global] driver = "virtio-blk-pci" property = "vectors" value = "0" This can also be used to set properties for devices which are not created via -device but implicitly via machine init, i.e. -global isa-fdc,driveA=<name> This patch uses the mechanism which configures properties for the compatibility machine types (pc-0.10 & friends). The command line takes precedence over the machine type values.

| * monitor: Command-line flag to enable control modeLuiz Capitulino2009-12-031-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a flag called 'control' to the '-monitor' command-line option. This flag enables control mode. The syntax is: qemu [...] -monitor control,<device> Where <device> is a chardev (excluding 'vc', for obvious reasons). For example: $ qemu [...] -monitor control,tcp:localhost:4444,server Will run QEMU in control mode, waiting for a client TCP connection on localhost port 4444. NOTE: I've tried using QemuOpts for this, but turns out that it will try to parse the device part, which should be untouched.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds -readconfig and -writeconfig command line switches to read/write QemuOpts from config file. In theory you should be able to do: qemu < machine config cmd line switches here > -writeconfig vm.cfg qemu -readconfig vm.cfg In practice it will not work. Not all command line switches are converted to QemuOpts, so you'll have to keep the not-yet converted ones on the second line. Also there might be bugs lurking which prevent even the converted ones from working correctly. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

| * Enable host-clock-based RTCJan Kiszka2009-10-051-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Switch RTC emulations to the new host_clock instead of vm_clock by default. This has the advantage that the emulated RTC will follow automatically the host time while it might be tuned via NTP. vm_clock can still be selected by passing '-rtc clock=vm' on the command line. Note that some RTC emulations (at least M48T59) already use the host time unconditionally while others (namely MC146818) do not. This patch introduces the required infrastructure for selecting the base clock but only converts MC146818 for now.

This patch adds the infrastructure and converts the null device. The patch brings two new functions: qemu_chr_open_opts() same as qemu_chr_open(), but uses QemuOpts instead of a option char string. qemu_chr_parse_compat() accepts a traditional chardev option string, returns the corresponding QemuOpts instance, to handle backward compatibility. The patch also adds a new -chardev switch which can be used to create named+unconnected chardevs, like this: -chardev null,id=test This uses the new qemu_chr_open_opts. Thus with this patch alone only the null device works. The other devices will follow ... Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

| * raw-posix: add Linux native AIO supportChristoph Hellwig2009-08-271-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that do have a nicer interface to work against we can add Linux native AIO support. It's an extremly thing layer just setting up an iocb for the io_submit system call in the submission path, and registering an eventfd with the qemu poll handler to do complete the iocbs directly from there. This started out based on Anthony's earlier AIO patch, but after estimated 42,000 rewrites and just as many build system changes there's not much left of it. To enable native kernel aio use the aio=native sub-command on the drive command line. I have also added an option to qemu-io to test the aio support without needing a guest.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The ne2k is an ancient card that performs pretty terribly under QEMU. In many modern OSes, there is no longer drivers available for the ne2k. Switch the default network adapter to e1000. This card is more widely suppported and performs rather well under QEMU. There may be very old OSes that had a ne2k driver but not an e1000 driver but I think this is likely the exception. I think the average user is better served with an e1000 vs ne2k.

| * Unbreak large mem support by removing kqemuAnthony Liguori2009-08-241-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
