2015-01-08memory: API to allocate resizeable RAM MRMichael S. Tsirkin1-0/+17
Add API to allocate resizeable RAM MR. This looks just like regular RAM generally, but has a special property that only a portion of it (used_length) is actually used, and migrated. This used_length size can change across reboots. Follow up patches will change used_length for such blocks at migration, making it easier to extend devices using such RAM (notably ACPI, but in the future thinkably other ROMs) without breaking migration compatibility or wasting ROM (guest) memory. Device is notified on resize, so it can adjust if necessary. Note: nothing prevents making all RAM resizeable in this way. However, reviewers felt that only enabling this selectively will make some class of errors easier to detect. Signed-off-by: Michael S.

In addition, for VFIO we will be introducing some private per-AdressSpace information, which must be disposed of before the AddressSpace itself is destroyed.

2014-03-09memory_region_present: return false if address is not found in child ↵Igor Mammedov1-1/+1
MemoryRegion Windows XP shows COM2 port as non functional in "Device Manager" although no COM2 port backing device is present in QEMU. This regression is really due to 3bb28b7208b349e7a1b326e3c6ef9efac1d462bf? memory: Provide separate handling of unassigned io ports accesses That is caused by the fact that QEMU reports to OSPM that device is present by setting 5th bit in PII4XPM.pci_conf[0x67] register when COM2 doesn't exist. It happens due to memory_region_present(io_as, 0x2f8) returning false positive since 0x2f8 address eventually translates into catchall io_as address space. Fix memory_region_present(parent, addr) by returning true only if addr maps into a MemoryRegion within parent (excluding parent itself), to match its doc comment. While at it fix copy/paste error in memory_region_present() doc comment. Note: this is a temporary hack: we really need better handling for unassigned regions, we should avoid fallback regions since they are bad for performance (breaking radix tree assumption that the data structure is sparsely populated); for memory we need to fix this to implement PCI master abort properly, anyway.

By making the priority values signed rather than unsigned, we make it more convenient to implement a situation where one "background" region should appear only where no other region exists: rather than having to explicitly specify a high priority for all the other regions, we can let them take the default (zero) priority and specify a negative priority for the background region.
