2012-01-19msi: Generalize msix_supported to msi_supportedJan Kiszka1-2/+0
Rename msix_supported to msi_supported and control MSI and MSI-X activation this way. That was likely to original intention for this flag, but MSI support came after MSI-X. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>

2009-11-09pci: introduce pcibus_t to represent pci bus address/size instead of uint32_tIsaku Yamahata1-1/+2
This patch is preliminary for 64 bit BAR support. Introduce dedicated type, pcibus_t, to represent pci bus address/size instead of uint32_t. Later this type will be changed to uint64_t.

2009-10-05qemu: clean up target page usage in msixMichael S. Tsirkin1-3/+2
Since cpu_register_phys_memory does not require size to be a multiple of target page size, simply make msix page size 0x1000. Do this in msix, reverting part of 5e520a7d500ec2569d22d80f9ef4272a34cb3c80, as we no longer have to pass target page around. Signed-off-by: Michael S.

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-1/+1
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

2009-06-24qemu/pci: MSI-X support functionsMichael S. Tsirkin1-0/+34
Add functions implementing MSI-X support. First user will be virtio-pci. Note that platform must set a flag to declare MSI supported: this is a safety measure to avoid breaking platforms which should support MSI-X but currently lack this in the interrupt controller emulation. For PC this will be set by APIC. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
