impl SharedMemoryManager

pub fn new(numa_nodes: usize) -> Self

Create a new shared memory manager

pub fn create_region( &self, owner: ProcessId, size: usize, cache_policy: CachePolicy, numa_node: Option<u32>, ) -> Result<u64>

Create a new shared memory region

pub fn get_region(&self, id: u64) -> Option<u64>

Get a shared region by ID

pub fn remove_region(&self, id: u64) -> Result<()>

Remove a shared region

pub fn share_with(&self, region_id: u64, target: ProcessId) -> Result<()>

Grant a process access to a shared region.

Records a pending mapping for the target process. The actual page- table insertion happens when the process calls sys_ipc_map_memory.

pub fn numa_usage(&self, node: u32) -> Option<u64>
