/kernel/trunk/ |
Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares... |

Minor changes. |

/kernel/trunk/ |
sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse. |

/kernel/trunk/ |
sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32. |
|

/kernel/trunk/ |
Move i8042 driver to genarch as it might be used by more architectures. |
|
883 |
6796 d 11 h |
jermar |
/kernel/trunk/arch/sparc64/ |
sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore. |
|
877 |

/kernel/trunk/arch/sparc64/ |
Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly. |
|
873 |
6798 d 11 h |
jermar |
/kernel/trunk/arch/sparc64/ |
sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose. |
|
868 |
6800 d 8 h |
jermar |
/kernel/trunk/arch/sparc64/src/mm/ |
Add missing file. |
|
867 |
6800 d 8 h |
jermar |
/kernel/trunk/ |
Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory. |
|
863 |
6800 d 23 h |
jermar |
/kernel/trunk/arch/sparc64/ |
sparc64 work.
Add initial TLB miss handlers. |
|

sparc64 work.
Relocate kernel to 4M. |
|
830 |
6812 d 9 h |
jermar |
/kernel/trunk/ |
Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init(). |
|
823 |
6813 d 23 h |

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization. |
|
821 |
6814 d 0 h |
jermar |
/kernel/trunk/arch/sparc64/src/mm/ |
Do not add CONFIG_STACK_SIZE to kernel.size. |
|
820 |
6814 d 0 h |
jermar |
/kernel/trunk/ |
Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t. |
|
815 |
6814 d 10 h |
jermar |
/kernel/trunk/ |
Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile. |
|
813 |
6814 d 23 h |
jermar |
/kernel/trunk/ |
Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped. |
|

6816 d 8 h |

/kernel/trunk/ |
Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations. |
|
792 |
6816 d 9 h |
jermar |
/kernel/trunk/ |
Page hash table architectures now use generic hash table to manage
mappings. |
|
756 |
6821 d 23 h |
jermar |
/kernel/trunk/ |
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. |
|

6832 d 5 h |

/kernel/trunk/ |
Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs. |
|
727 |
6834 d 1 h |
jermar |
/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
684 |
6845 d 8 h |
jermar |
/kernel/trunk/ |
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. |
|

/kernel/trunk/ |
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. |
|

Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

TBA must be set before a function call when MMU is switched off. |
|

/kernel/trunk/arch/sparc64/ |
sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table. |
|
617 |
6871 d 0 h |
jermar |
/kernel/trunk/arch/sparc64/ |
sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid). |
|

6871 d 23 h |
jermar |

sparc64 work.
More ITLB and DTLB controlling functions. |
