Replace nonblocking argument of waitq_sleep_timeout with flags that specify mode of operation.
Now a flag can be used to specify interruptible sleep.
Modify waitq_interrupt_sleep() to only interrupt threads that used this flag.

Reference counting for futexes. |
|

Better SYS_IO |
|

/kernel/trunk/generic/include/ |
Added error code for timeouts. |
|

6565 d 21 h |

Correct realtime clock communication. |
|
| 1437 |
6565 d 22 h |

/kernel/trunk/generic/src/mm/ |
Fix used_space_insert() to correctly service an empty used_space B+tree. |
|

/kernel/trunk/generic/src/mm/ |
Fight TLB inconsistency by proper placing of tlb_shootdown_start() and tlb_shootdown_finalize() in as.c. |
|
| 1434 |
6566 d 1 h |

/kernel/trunk/ |
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform. |
|
| 1433 |
6566 d 4 h |
jermar |
/kernel/trunk/generic/src/time/ |
Fix critical bug in timeout processing introduced several hours ago. |
|
| 1431 |
6566 d 8 h |
jermar |
/kernel/trunk/generic/ |
Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate. |
|
| 1429 |
6566 d 9 h |
jermar |
/kernel/trunk/generic/ |
Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired. |
|
| 1428 |
6566 d 20 h |
palkovsky |
/kernel/trunk/generic/ |
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. |
|
| 1426 |
6566 d 21 h |

/kernel/trunk/generic/src/mm/ |
Support for sharing address space areas backed up by ELF image. |
|
| 1425 |
6566 d 23 h |
jermar |
/kernel/trunk/generic/ |
Make address space backend data a union. |
|
| 1424 |
6567 d 1 h |
jermar |
/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. |
|
| 1423 |
6567 d 5 h |
jermar |
/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
| 1417 |
6568 d 22 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. |
|
| 1416 |
6569 d 9 h |
jermar |
/kernel/trunk/generic/ |
Make implementation of condition variables compliant with their definition.
Signal operation must become a no-op if there is no thread in the wait operation.
Remove condvar_trywait() which has no meaning after this change. |
|
| 1415 |
6569 d 10 h |

/kernel/trunk/generic/ |
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |
|
| 1414 |
6569 d 10 h |
jermar |
/kernel/trunk/generic/src/synch/ |
Small fixes in futex.c.
PTE_GET_FRAME() returns frame address, not PFN.
Update comments. |
|
| 1413 |
6569 d 21 h |
jermar |
/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
| 1411 |
6570 d 2 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. |
|
| 1409 |
6570 d 20 h |
jermar |
/kernel/trunk/generic/ |
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends. |
|
| 1403 |
6572 d 9 h |
jermar |
/kernel/trunk/generic/src/mm/ |
Fixes of the used_space management code.
Switch as_area_destroy() and as_area_resize() to use the used_space map.
as_area_steal() not switched as it will undergo further changes. |
|

6572 d 23 h |

/kernel/trunk/ |
Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc(). |

ppc32: identically map the whole physical memory
fix page hash table refill logic |
|
| 1387 |
6573 d 4 h |
jermar |
/kernel/trunk/generic/ |
Add used_space_insert() and used_space_remove().
These are the alpha versions of functions that
will help to map used and unused portions of address
space areas. Currently unused, but many as_area operations
will be more efficient when the used space B+tree map
is used. |
