Module mmtk::util::heap::layout::vm_layout_constants [−][src]
Constants
| AVAILABLE_BYTES | Size of the address space available to the MMTk heap. |
| AVAILABLE_END | Highest virtual address available for MMTk to manage. The address space between HEAP_END and AVAILABLE_END comprises memory directly managed by the VM, and not available to MMTk. |
| AVAILABLE_START | Lowest virtual address available for MMTk to manage. The address space between HEAP_START and AVAILABLE_START comprises memory directly managed by the VM, and not available to MMTk. |
| BYTES_IN_CHUNK | Coarsest unit of address space allocation. |
| HEAP_END | |
| HEAP_START | |
| LOG_ADDRESS_SPACE | log_2 of the addressable virtual space |
| LOG_BYTES_IN_CHUNK | log_2 of the coarsest unit of address space allocation. |
| LOG_MAX_CHUNKS | log_2 of the maximum number of chunks we need to track. Only used in 32-bit layout. |
| LOG_MMAP_CHUNK_BYTES | Granularity at which we map and unmap virtual address space in the heap |
| LOG_PAGES_IN_SPACE64 | log_2 of the number of pages in a 64-bit space |
| LOG_SPACE_EXTENT | An upper bound on the extent of any space in the current memory layout |
| MAX_CHUNKS | Maximum number of chunks we need to track. Only used in 32-bit layout. |
| MAX_SPACE_EXTENT | An upper bound on the extent of any space in the current memory layout |
| MMAP_CHUNK_BYTES | |
| PAGES_IN_CHUNK | Coarsest unit of address space allocation, in pages |
| PAGES_IN_SPACE64 | The number of pages in a 64-bit space |
| SPACE_MASK_64 | |
| SPACE_SHIFT_64 | |
| SPACE_SIZE_64 | |
| VM_SPACE_SIZE |
