/kernel/trunk/ |
Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction). |

Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well. |

/kernel/trunk/ |
Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths. |

accessed before paging is initialized. |

Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly. |
|
| 1021 |
6675 d 4 h |

/kernel/trunk/ |
Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time. |
|

6677 d 2 h |

/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. |
|
| 955 |
6677 d 3 h |
palkovsky |
/kernel/trunk/ |
Added kernel IPC functionality. |
|
| 940 |
6678 d 3 h |
jermar |
/kernel/trunk/ |
Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|
| 938 |
6678 d 4 h |
jermar |
/kernel/trunk/ |
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention. |
|

/kernel/trunk/ |
ELF framework for all archs. SPARC V9 not tested to compile. |
|
| 895 |
6691 d 2 h |
jermar |
/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. |
|
| 894 |
6691 d 5 h |

/kernel/trunk/ |
Move i8042 driver to genarch as it might be used by more architectures. |
|
| 860 |
6697 d 22 h |
decky |
/kernel/trunk/ |
indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy |
|

/kernel/trunk/ |
Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|
| 831 |
6708 d 6 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 |
6709 d 5 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 |
6710 d 10 h |

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

6711 d 20 h |
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? :-/ |
|
| 803 |
6711 d 23 h |

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

Userspace now starts executing correctly. |
|
| 800 |

/kernel/trunk/arch/amd64/include/ |
Split AMD interrupt.h from ia32 version. |
|
| 799 |
6712 d 1 h |

/kernel/trunk/ |
Preliminary work on AMD userspace. |
|
| 765 |
6716 d 1 h |

/kernel/trunk/ |
Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
| 763 |
6716 d 7 h |
jermar |
/kernel/trunk/ |
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |
|
| 760 |
6716 d 10 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 |
6717 d 22 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. |
|
| 727 |
6730 d 0 h |

/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
| 703 |
6736 d 9 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(). |
