2012-10-22memory: manage coalesced mmio via a MemoryListenerAvi Kivity6-39/+27
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.

2012-10-15memory: provide defaults for MemoryListener operationsAvi Kivity1-6/+17
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 Kivity2-29/+48
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 Kivity2-10/+22
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 Kivity1-15/+24
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 Kivity2-1/+38
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 Kivity1-39/+44
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 Kivity1-3/+2
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 Kivity4-12/+5
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.

2012-10-12hw/ds1338: Remove 'now' field from state structPeter Maydell1-20/+21

2012-10-12hw/ds1338: Recapture current time when register pointer wraps aroundPeter Maydell1-17/+42

2012-10-12hw/ds1338: Fix mishandling of register pointerPeter Maydell1-7/+13
Correct several deficiencies in the handling of the register pointer: * it should wrap around after 0x3f, not 0xff * guard against the caller handing us an out of range pointer (on h/w this can never happen, because only a 7 bit value is transferred over the I2C bus) * there was confusion over whether nvram[] holds only the 56 bytes of guest-accessible NVRAM, or also the secondary registers which hold the value of the clock captured at the start of a multibyte read. Correct to consistently be the latter, by fixing the array size and the offset used for NVRAM writes. * ds1338_send was attempting to use 'data' as both the data and the register offset simultaneously, which meant that writes to any register were broken; fix to use the register pointer.
