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. |

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions. |

Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.

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. |

palkovsky |
/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. |

Improved uspace threads.
ia64 needs fixing. |

Modified debugger to be able to coexist in AS watch mode and SMP. |
|
| 1074 |
6671 d 15 h |
palkovsky |
/kernel/trunk/ |
Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well. |

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. |

6673 d 15 h |
jermar |
/kernel/trunk/ |
Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word. |

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. |

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

Fix e820list on ia32. |
|
| 906 |
6686 d 3 h |

/kernel/trunk/ |
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. |

Revive OFW console code and use it before the kernel switches to standalone console.
ia32 + ia64 cosmetic changes. |
