| * ROGUE Device Virtual Address Space Definitions | ||
| * | ||
| * This file defines the ROGUE virtual address heaps that are used in | ||
| * application memory contexts. It also shows where the Firmware memory heap | ||
| * fits into this, but the firmware heap is only ever created in the | ||
| * kernel driver and never exposed to userspace. | ||
| * | ||
| * ROGUE_PDSCODEDATA_HEAP_BASE and ROGUE_USCCODE_HEAP_BASE will be programmed, | ||
| * on a global basis, into ROGUE_CR_PDS_EXEC_BASE and ROGUE_CR_USC_CODE_BASE_* | ||
| * respectively. Therefore if client drivers use multiple configs they must | ||
| * still be consistent with their definitions for these heaps. | ||
| * | ||
| * Base addresses have to be a multiple of 4MiB. | ||
| * Heaps must not start at 0x0000000000, as this is reserved for internal | ||
| * use within the driver. | ||
| * Range comments, those starting in column 0 below are a section heading of | ||
| * sorts and are above the heaps in that range. Often this is the reserved | ||
| * size of the heap within the range. | ||
