2009-02-05hw: remove error handling from qemu_malloc() callers (Avi Kivity)aliguori
Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6529 c046a42c-6fe2-441c-8c8c-71466251a162
2009-02-01Add and use #defines for PCI device classesblueswir1
This patch adds and uses #defines for PCI device classes and subclases, using a new pci_config_set_class() function, similar to the recently added pci_config_set_vendor_id() and pci_config_set_device_id(). Change since v1: fixed compilation of hw/sun4u.c Signed-off-by: Stuart Brady <stuart.brady@gmail.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6491 c046a42c-6fe2-441c-8c8c-71466251a162
2009-01-29Don't notify virtio devices before S_DRIVER_OK (Mark McLoughlin)aliguori
Current Linux guests oops if the host notifies of a config change before a driver has been bound to the device. It's pretty pointless for us to do notify of config changes before status is S_DRIVER_OK anyway, so let's just not do it.

2009-01-26Define PCI vendor and device IDs in pci.h (Stuart Brady)aliguori
This patch defines PCI vendor and device IDs in pci.h (matching those from Linux's pci_ids.h), and uses those definitions where appropriate. Change from v1: Introduces pci_config_set_vendor_id() / pci_config_set_device_id() accessors as suggested by Anthony Liguori.

2008-12-04Fix windows build after virtio changesaliguori
Windows does not have sys/uio.h and does not have err.h. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5877 c046a42c-6fe2-441c-8c8c-71466251a162
2008-12-04Remove TARGET_PAGE_SIZE from virtio interface (Hollis Blanchard)aliguori
TARGET_PAGE_SIZE should only be used internal to qemu, not in guest/host interfaces. The virtio frontend code in Linux uses two constants (PFN shift and vring alignment) for the interface, so update qemu to match. I've tested this with PowerPC KVM and confirmed that it fixes virtio problems when using non-TARGET_PAGE_SIZE pages in the guest.

2008-12-04Virtio core supportaliguori
This patch adds core support for VirtIO. VirtIO is a paravirtualization framework that has been in Linux since 2.6.21. A PCI transport has been available since 2.6.25. Network drivers are also available for Windows. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5869 c046a42c-6fe2-441c-8c8c-71466251a162
