* exec/memory: Add symbol for memory listener priority for device backendIsaku Yamahata2023-06-281-1/+1
| | | | | | | | | | | | | Add MEMORY_LISTENER_PRIORITY_DEV_BACKEND for the symbolic value for memory listener to replace the hard-coded value 10 for the device backend. No functional change intended.

* hw/remote: Add missing includePhilippe Mathieu-Daudé2022-02-211-0/+1
| | | | | | | | | | | | | | | | | | | | Currently "qemu/error-report.h" is implicitly included, however if headers in include/ get refactored, we get: hw/remote/proxy-memory-listener.c: In function ‘proxy_memory_listener_commit’: hw/remote/proxy-memory-listener.c:183:9: error: implicit declaration of function ‘error_report’; did you mean ‘error_report_err’? [-Werror=implicit-function-declaration] 183 | error_report("Number of fds is more than %d", REMOTE_MAX_FDS); | ^~~~~~~~~~~~ | error_report_err Add the missing "qemu/error-report.h" header to avoid that.

* multi-process: Synchronize remote memoryJagannathan Raman2021-02-101-0/+227
Add ProxyMemoryListener object which is used to keep the view of the RAM in sync between QEMU and remote process. A MemoryListener is registered for system-memory AddressSpace. The listener sends SYNC_SYSMEM message to the remote process when memory listener commits the changes to memory, the remote process receives the message and processes it in the handler for SYNC_SYSMEM message.
