C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64. |

sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work |

Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.
A lot of formatting and indentation fixes. |

sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.
Little bit of formatting and indentation. |

Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.). |

Remove unneeded FRAME_PANIC.
Fix some things broken by last commit. |

Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling. |

Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares... |

Kernel doxygen comments updated. |

Make use of thread_join_timeout() and thread_detach() in kernel.
Improved comments in slab.h. |

Function for destroying address space for which there is no other reference in the kernel. |

Added 256K slab, so that AMD can boot (until ELF loader is fixed).
Added AS_AREA_RECV so that the caller can receive AS_AREA. |

Make address space backend data a union. |

/kernel/trunk/ |
Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now. |

Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
1417 |
6659 d 16 h |
jermar |
/kernel/trunk/generic/ |
Modify as_area_share() to accept destination area flags bitmask from the sender
(i.e. the sender can limit access mode to the shared area for the recipient).
Modify IPC_M_AS_AREA_SEND code to support this. Arguments for sender: arg1=as_area,
arg2=size, arg3=flags_mask.
The mechanism seems to work, but the page fault handlers need to be altered to
distinguish between faults under different access modes. |

Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |

Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|

6660 d 20 h |
jermar |
/kernel/trunk/ |
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault. |
