/kernel/trunk/ |
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|
| 938 |
6653 d 13 h |

/kernel/trunk/ |
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention. |

ELF framework for all archs. SPARC V9 not tested to compile. |

Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared |

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. |

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. |
|

Move i8042 driver to genarch as it might be used by more architectures. |

Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|
| 831 |
6683 d 15 h |

/kernel/trunk/ |
Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared). |

Unimportant changes regarding FPU context. |
|
| 825 |
6684 d 14 h |

/kernel/trunk/ |
Remove WAKEUP_IPI stuff.
Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL. |
|
| 822 |
6685 d 8 h |

Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones. |
|
| 820 |
6685 d 9 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. |
|
| 814 |
6685 d 19 h |

/kernel/trunk/ |
Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print. |

/kernel/trunk/arch/amd64/src/boot/ |
I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics. |
|

/kernel/trunk/arch/amd64/ |
Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/ |
|
| 803 |
6687 d 8 h |

/kernel/trunk/arch/amd64/ |
Basic amd syscall support. |

Userspace now starts executing correctly. |
|

Split AMD interrupt.h from ia32 version. |

fix init_addr virtual address |
|
| 793 |
6687 d 16 h |
jermar |
/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. |
|
| 778 |
6689 d 12 h |

Fixed boot process not to call malloc when slab not initialized.
Added simics workaround. |
|

/kernel/trunk/ |
SLAB allocator now uses itself for all its internal structures.
Added description of allocator.
Removed messy_stack_trace from amd64, as it would scroll away important
part of exception. |
|
| 765 |
6691 d 10 h |

/kernel/trunk/ |
Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
| 763 |
6691 d 16 h |
jermar |
/kernel/trunk/ |
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
| 760 |
6691 d 19 h |

/kernel/trunk/ |
mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.
Remove GET_PTL0_ADDRESS from kernel.
Update sparc64 comments in barrier.h. |
|
| 756 |
6693 d 7 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. |
|
| 755 |
6694 d 7 h |
jermar |
/kernel/trunk/ |
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. |
|
| 727 |
6705 d 9 h |
jermar |
/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
| 717 |
6709 d 13 h |
decky |
/kernel/trunk/ |
remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time |
|
| 703 |
6711 d 18 h |
jermar |
/kernel/trunk/ |
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(). |

AMD64 SMP boots again |
|

6716 d 12 h |
decky |
/kernel/trunk/arch/amd64/ |
make AMD64 boot again (using grub, see /boot tree), SMP is still broken |
|

6716 d 13 h |

/kernel/trunk/arch/amd64/ |
break AMD64, will be fixed soon |
