| | | | | | | | | | | | | | | | Since pci.c creates network devices, anything that links against pci.c (everything) has to link against all network devices. Since virtio-net also requires virtio, we might as well link every target against all of the virtio devices. This suggests that the pci.c network device creation function needs some refactoring.

* target-ppc: IBM PowerPC 440EP Bamboo reference board emulationaurel322008-12-161-1/+1
| | | | | | | | | | | | | | | | | Since most IO devices are integrated into the 440EP chip, "Bamboo support" mostly entails implementing the -kernel, -initrd, and -append options. These options are implemented by loading the guest as if u-boot had done it, i.e. loading a flat device tree, updating it to hold initrd addresses, ram size, and command line, and passing the FDT address in r3. Since we use it with KVM, we enable the virtio block driver and include hooks necessary for KVM support.

This patch is a little unusual in that qemu doesn't actually emulate the 440 core, but we use this board code with KVM (which does).

| | | | | | | | | | | | | | To implement the -kernel, -initrd, and -append options, 4xx board emulation must load the guest kernel as if firmware had loaded it. Where u-boot would be the firmware, we must load the flat device tree into memory and set key fields such as /chosen/bootargs.

* Replace posix-aio with custom thread poolaliguori2008-12-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | glibc implements posix-aio as a thread pool and imposes a number of limitations. 1) it limits one request per-file descriptor. we hack around this by dup()'ing file descriptors which is hideously ugly 2) it's impossible to add new interfaces and we need a vectored read/write operation to properly support a zero-copy API. What has been suggested to me by glibc folks, is to implement whatever new interfaces we want and then it can eventually be proposed for standardization. This requires that we implement our own posix-aio implementation though. This patch implements posix-aio using pthreads. It immediately eliminates the need for fd pooling. It performs at least as well as the current posix-aio code (in some circumstances, even better).

* Add KVM support to QEMUaliguori2008-11-051-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds very basic KVM support. KVM is a kernel module for Linux that allows userspace programs to make use of hardware virtualization support. It current supports x86 hardware virtualization using Intel VT-x or AMD-V. It also supports IA64 VT-i, PPC 440, and S390. This patch only implements the bare minimum support to get a guest booting. It has very little impact the rest of QEMU and attempts to integrate nicely with the rest of QEMU. Even though this implementation is basic, it is significantly faster than TCG. Booting and shutting down a Linux guest: w/TCG: 1:32.36 elapsed 84% CPU w/KVM: 0:31.14 elapsed 59% CPU Right now, KVM is disabled by default and must be explicitly enabled with -enable-kvm.

* Move CharDriverState code out of vl.caliguori2008-10-311-1/+1
| | | | | | | | | | | | The motivating goal behind this is to allow other tools to use the CharDriver code. This patch is pure code motion except for the Makefile changes and the copyright/header in qemu-char.c.

* Introduce TCP live migration protocolaliguori2008-10-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This patch introduces a tcp protocol for live migration. It can be used as follows: qemu-system-x86_64 -hda ~/images/linux-test.img -monitor stdio <vm runs for a while> (qemu) migrate tcp:localhost:1025 On the same system: qemu-system-x86_64 -hda ~/images/linux-test.img -incoming tcp:localhost:1025 The monitor can be interacted with while waiting for an incoming live migration.
