Detailed Description

A structure to represent shared memory context

Member Data Documentation

u8* hermes::SharedMemoryContext::shm_base

A pointer to the beginning of shared memory.

ptrdiff_t hermes::SharedMemoryContext::buffer_pool_offset

The offset from the beginning of shared memory to the BufferPool.

ptrdiff_t hermes::SharedMemoryContext::metadata_manager_offset

The offset from the beginning of shared memory to the Metadata Arena.

u64 hermes::SharedMemoryContext::shm_size

The total size of the shared memory (needed for munmap).

BufferOrganizer* hermes::SharedMemoryContext::bo

This will only be valid on Hermes cores, and NULL on client cores.

std::vector<std::vector<std::string> > hermes::SharedMemoryContext::buffering_filenames

vector of buffering file names

int hermes::SharedMemoryContext::open_files[kMaxDevices][kMaxBufferPoolSlabs]

2D array of open files for each device and buffer pool slab

FILE* hermes::SharedMemoryContext::swap_file

pointer to swap file
