Added basic FPU context (not working).
Added CPU utilities from ia32

Fix nasty bug in arch/mm/frame.c.
frame_region_not_free() takes address as its second argument, not size. |

Resolved mapping of e820 boot area, so that it can be accessed as
e820table from 32-bit mode and e820table_boot from real mode. |

Do not use the unmapped addresses of e820 kernel structures.
Use PA2KA() to access the e820 counter and memtable. |

Better types for ia32 drivers, so that they can be reused in amd64.
Build script cleanup amd64.
New code / not working yet / in amd64. |

Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy(). |

Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.
Cleanup. |

1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option |

Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.
Get rid of write_dr0() and read_dr0() on IA-32.
Get rid of cpu_private_data and cpu_private_data_t. |

Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'.
Fix heap initialization to take 'heap_delta' into account.
Implement IA-64 get_stack_base().
Adjust SP_DELTA's to consider one extra word on stack.
(So that the stack pointer is within appropriate limits even on IA-64).
More #include cleanup. |
|
| 177 |

Add some comments to IA-32 src/boot/boot.S and src/smp.S.
Make the boot stack start on page boundary.
This is required by get_stack_base().
Define 'THE' macro.
Implement preemption_disable() and preemption_enable().
Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.
Reduction of many #include paths. |

Small changes.
Coding style fix in main.c.

Preparations for weaker preemption model.
Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy. |

Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.
Remove two unnecessary cpu_priority_high() calls. |

For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA(). |
|

/SPARTAN/trunk/ |
Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.
Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code. |
|

Switch over to per vm_t page tables. (breaks ia32 userspace)
Define dummy memcopy() for amd64 and ppc to satisfy compiler.
Get rid of problematic #include <arch/mm/page.h> in mm/page.h.
Indentation fixes and small changes here and there. |
