The 32-bit virtual address space (4 GB) is partitioned as:
| Range | Size | Owner | Description | |----------------|--------|----------------------|--------------------------------------| | 0x00000000 | 1 GB | Space 0 (KGO Kernel) | Scheduler, IPC, space switcher | | 0x40000000 | 1 GB | Space 1 | App / RTOS instance 1 | | 0x80000000 | 1 GB | Space 2 | App / RTOS instance 2 | | 0xC0000000 | 1 GB | Shared Region | Cross-space mailboxes, shared memory |
Each space sees its own 0x40000000 base via MMU remapping (per-space page tables). The shared region at 0xC0000000 is identity-mapped and protected by access keys.
The project uses the following data structures:
To build the KGO Multi Space 32-bit project, follow these steps:
The KGO Multi Space 32-bit project aims to provide a robust and efficient solution for managing multiple spaces in a 32-bit environment. The project focuses on delivering a high-quality, open-source implementation that meets the needs of developers and users.
