structure. This makes it possible to pre-allocate PTEs for the kernel, which is necessary for a reliable implementation of pmap_kenter(). This also avoids wasting space (about 48 bytes per page) for kernel mappings and user mappings of memory-mapped devices. This also fixes a bug with the previous version where the implementation required the pv_entry structure to be physically contiguous but did not enforce this (the structure size was not a power of two). This meant that the pv_entry free list was quickly corrupted as soon as the system was even mildly loaded. |
