Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults. |

Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there. |

/kernel/trunk/arch/ |
Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing. |
|

/kernel/trunk/arch/ |
Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit. |
|

6700 d 4 h |

/kernel/trunk/ |
Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update. |
|

/kernel/trunk/arch/ |
Replace assembly from pm.c with new inline functions defined in asm.h. |
|

6700 d 7 h |
jermar |
/kernel/trunk/ |
Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64. |

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

/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. |

/kernel/trunk/ |
Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized. |
|

Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly. |
|

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. |
|

Fixed invlpg for ia32 & amd64. |
|

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

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

Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader. |
|

6732 d 3 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. |
|
895 |
6745 d 1 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. |
|

6745 d 4 h |

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 |
6762 d 5 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 |
6763 d 4 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. |

Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.

/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? :-/ |

Basic amd syscall support. |
