* pci: use memory core for iommu supportAvi Kivity2013-06-201-20/+19
| | | | | | | | | | | | | | Use the new iommu support in the memory core for iommu support. The only user, spapr, is also converted, but it still provides a DMAContext interface until the non-PCI bits switch to AddressSpace. Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Avi Kivity <avi.kivity@gmail.com> [ Do not calls memory_region_del_subregion() on the device's bus_master_enable_region, it is an alias; return an AddressSpace from the IOMMU hook and remove the destructor hook. - David Gibson ] Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* pci: refuse empty ROM filesStefan Hajnoczi2013-03-261-1/+6
| | | | | | | | | | | | | | | A zero size ROM file is invalid and should produce a warning. Attempting to use a zero size file ends up hitting an assertion qemu_ram_set_idstr() because RAMBlocks with duplicate addresses are allocated - due to zero size the allocator doesn't increment the next available RAMBlock offset. Also convert __FUNCTION__ to __func__ while we're touching this code. There are no other __FUNCTION__ instances in pci.c anymore.

* pci: Fix INTx routing notifier recursionAlex Williamson2013-03-261-3/+4
| | | | | | | | | | | | For some reason we recurse to fire the INTx routing notifier for each child of a bus, for each possible device of a bus. That means that if we add a root port, the notifier gets called for that bridge 256 times. If we add an upstream switch behind that root port, 256^2. But of course we need a downstream switch, 256^3. This starts to be noticeable. Stop the insanity. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* pci_bridge: factor out common codeMichael S. Tsirkin2013-03-261-10/+4
| | | | | | | | Reuse common code in pcie_port, override the hardwired-to-0 bits per PCI Express spec. No functional change but makes the code easier to follow. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* pci: Teach PCI Bridges about VGA routingAlex Williamson2013-03-261-0/+4
| | | | | | | | | | | | | | | | Each PCI Bridge has a set of implied VGA regions that are enabled when the VGA bit is set in the bridge control register. This allows VGA devices behind bridges. Unfortunately with VGA Enable, which we formerly allowed but didn't back, comes along some required VGA baggage. VGA Palette Snooping is required, along with VGA 16-bit decoding. We don't yet have support for palette snooping. We also don't have support for 10-bit VGA aliases, the default mode, but we enable the register, even on root ports, to avoid confusing guests. Fortunately there's likely nothing from this century that requires these features, so the missing bits are noted with TODOs.

* pci: Add PCI VGA helpersAlex Williamson2013-03-261-0/+61
| | | | | | | | | | Allow devices to register VGA memory regions for handling PCI spec defined VGA I/O port and MMIO areas. PCI will attach these to the bus address spaces and enable them according to the device command register value. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S.

* Make all static TypeInfos constAndreas Färber2013-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.
