Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |

Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference |

Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64. |

Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |

Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created. |

Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas. |

Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping(). |

Fix zone_print_one() and zone_print_list().

- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup. |

Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface. |

sparc64 work.
Interrupt Levels 1 - 15 serviced.

Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's. |
|
| 651 |

/kernel/trunk/ |
remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work) |

sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7. |
|

6790 d 5 h |

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.
sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop. |
