2013-04-08hw: move hw/kvm/ to hw/i386/kvmPaolo Bonzini1-1924/+0
Peter requested the KVM GIC to be in hw/intc. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-04-08hw: move headers to include/Paolo Bonzini1-1/+1
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-02-11error: Clean up error strings with embedded newlinesMarkus Armbruster1-6/+6
The arguments of error_report() should yield a short error string without newlines. A few places try to print additional help after the error message by embedding newlines in the error string. That's nice, but let's do it the right way. Since I'm touching these lines anyway, drop a stray preposition and some tabs. We don't use tabs for similar messages elsewhere.

2013-01-09pci-assign: Enable MSIX on device to match guestAlex Williamson1-2/+15
When a guest enables MSIX on a device we evaluate the MSIX vector table, typically find no unmasked vectors and don't switch the device to MSIX mode. This generally works fine and the device will be switched once the guest enables and therefore unmasks a vector. Unfortunately some drivers enable MSIX, then use interfaces to send commands between VF & PF or PF & firmware that act based on the host state of the device. These therefore may break when MSIX is managed lazily. This change re-enables the previous test used to enable MSIX (see qemu-kvm a6b402c9), which basically guesses whether a vector will be used based on the data field of the vector table.

2012-10-29pci-assign: Use msi_get_message()Alex Williamson1-4/+1
pci-assign only uses a subset of the flexibility msi_get_message() provides, but it's still worthwhile to use it. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2012-10-23Rename target_phys_addr_t to hwaddrAvi Kivity1-12/+12
target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are reserved) and its purpose doesn't match the name (most target_phys_addr_t addresses are not target specific). Replace it with a finger-friendly, standards conformant hwaddr. Outstanding patchsets can be fixed up with the command git rebase -i --exec 'find -name "*.[ch]" | xargs s/target_phys_addr_t/hwaddr/g' origin Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2012-09-26pci-assign: use monitor_handle_fd_paramPaolo Bonzini1-9/+3
There is no need to open-code the choice between a file descriptor number or a named one. Just use monitor_handle_fd_param, which also takes care of printing the error message.

2012-09-10kvm: i386: Add classic PCI device assignmentJan Kiszka1-0/+1915
This adds PCI device assignment for i386 targets using the classic KVM interfaces. This version is 100% identical to what is being maintained in qemu-kvm for several years and is supported by libvirt as well. It is expected to remain relevant for another couple of years until kernels without full-features and performance-wise equivalent VFIO support are obsolete. A refactoring to-do that should be done in-tree is to model MSI and MSI-X support via the generic PCI layer, similar to what VFIO is already doing for MSI-X. This should improve the correctness and clean up the code from duplicate logic. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Acked-by: Acked-by: Michael S.
