/kernel/trunk/arch/ |
Fixed invlpg for ia32 & amd64. |

/kernel/trunk/ |
Add sys_mremap() syscall. |
|

/kernel/trunk/ |
Allowed userspace to include page.h. |
|

/kernel/trunk/ |
New synchronous ipc.
Widened syscall to support up to 5 parameters. |
|

/kernel/trunk/ |
Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate. |

/kernel/trunk/ |
Added kernel IPC functionality. |
|

/kernel/trunk/ |
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|
| 938 |
6667 d 9 h |
jermar |
/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. |
|

6680 d 7 h |

/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. |
|

6680 d 10 h |

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

indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy |

Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|
| 831 |
6697 d 11 h |
jermar |
/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). |
|
| 825 |
6698 d 10 h |
jermar |
/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. |
|
| 814 |
6699 d 15 h |

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

Doc updates. |

palkovsky |
/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? :-/ |
|

/kernel/trunk/arch/amd64/ |
Basic amd syscall support. |
|
| 802 |

Userspace now starts executing correctly. |
|

/kernel/trunk/arch/amd64/include/ |
Split AMD interrupt.h from ia32 version. |
|
| 799 |

/kernel/trunk/ |
Preliminary work on AMD userspace. |
|
| 765 |
6705 d 6 h |

Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
| 763 |
6705 d 12 h |
jermar |
/kernel/trunk/ |
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
| 760 |
6705 d 14 h |
jermar |
/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 |
6707 d 3 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. |
|

/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
| 703 |
6725 d 14 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(). |

|

6730 d 8 h |
decky |
/kernel/trunk/arch/amd64/ |
make AMD64 boot again (using grub, see /boot tree), SMP is still broken |
|

break AMD64, will be fixed soon |

Fixes of compilation of atomic. |

/kernel/trunk/ |
We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning. |
