2012-10-22memory: add address_space_destroy()Avi Kivity
Since address spaces can be created dynamically by device hotplug, they can also be destroyed dynamically. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22dma: make dma access its own address spaceAvi Kivity
Instead of accessing the cpu address space, use an address space configured by the caller. Eventually all dma functionality will be folded into AddressSpace, but we have to start from something. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22memory: per-AddressSpace dispatchAvi Kivity
Currently we use a global radix tree to dispatch memory access. This only works with a single address space; to support multiple address spaces we make the radix tree a member of AddressSpace (via an intermediate structure AddressSpaceDispatch to avoid exposing too many internals). A side effect is that address_space_io also gains a dispatch table. When we remove all the pre-memory-API I/O registrations, we can use that for dispatching I/O and get rid of the original I/O dispatch. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22s390: avoid reaching into memory core internalsAvi Kivity
use cpu_physical_memory_is_io() instead. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22memory: use AddressSpace for MemoryListener filteringAvi Kivity
Using the AddressSpace type reduces confusion, as you can't accidentally supply the MemoryRegion you're interested in. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22memory: move tcg flush into a tcg memory listenerAvi Kivity
We plan to make the core listener listen to all address spaces; this will cause many more flushes than necessary. Prepare for that by moving the flush into a tcg-specific listener. Later we can avoid registering the listener if tcg is disabled. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22memory: move address_space_memory and address_space_io out of memory coreAvi Kivity
With this change, memory.c no longer knows anything about special address spaces, so it is prepared for AddressSpace based DMA. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-22memory: manage coalesced mmio via a MemoryListenerAvi Kivity
Instead of calling a global function on coalesced mmio changes, which routes the call to kvm if enabled, add coalesced mmio hooks to MemoryListener and make kvm use that instead. The motivation is support for multiple address spaces (which means we we need to filter the call on the right address space) but the result is cleaner as well.

Removes quite a bit of useless code. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15memory: provide defaults for MemoryListener operationsAvi Kivity
Many listeners don't need to respond to all MemoryListener callbacks; provide suitable no-op defaults instead. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15memory: maintain a list of address spacesAvi Kivity
Instead of embedding knowledge of the memory and I/O address spaces in the memory core, maintain a list of all address spaces. This list will later be extended dynamically for other bus masters. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15memory: export AddressSpaceAvi Kivity
The DMA API will use an AddressSpace to differentiate among different initiators. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15memory: prepare AddressSpace for exportingAvi Kivity
AddressSpace contains a member, current_map, of type FlatView. Since we want to limit the leakage of internal types to public headers, switch to a pointer to a FlatView. There is no performance impact as this isn't used during lookups, only address space reconfigurations. Reviewed-by: Anthony Liguori <aliguori@us.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15xen_pt: use separate MemoryListeners for memory and I/OAvi Kivity
Using an unfiltered memory listener will cause regions to be reported fails multiple times if we have more than two address spaces. Use a separate listener for memory and I/O, and utilize MemoryListener's address space filtering to fix this. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15kvm: use separate MemoryListeners for memory and I/OAvi Kivity
The construct if (address_space == get_system_memory()) { // memory thing } else { // io thing } fails if we have more than two address spaces. Use a separate listener for memory and I/O, and utilize MemoryListener's address space filtering to fix this. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15vhost: use MemoryListener filtering to only monitor RAM address spaceAvi Kivity
Instead of checking manually, let the listener filter for us. This prepares us for DMA address spaces. Signed-off-by: Avi Kivity <avi@redhat.com>
2012-10-15memory: rename 'exec-obsolete.h'Avi Kivity
exec-obsolete.h used to hold pre-memory-API functions that were used from device code prior to the transition to the memory API. Now that the transition is complete, the name no longer describes the file. The functions still need to be merged better into the memory core, but there's no danger of anyone using them.

2012-10-13tcg-sparc: Drop use of Bicc in favor of BPccRichard Henderson
Now that we're always sparcv9, we can not bother using Bicc for 32-bit branches and BPcc for 64-bit branches and instead always use BPcc.

2012-10-13target-sparc: Don't compute full flags value so oftenRichard Henderson
