/kernel/trunk/ |
Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.

Small updates to ipc. |
|
| 1587 |
6723 d 7 h |
jermar |
/kernel/trunk/ |
task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space. |

Kill task when its main thread exits. |

Make ktaskclnp call ipc_cleanup and futex_cleanup. |
|
| 1582 |
6723 d 13 h |

/kernel/trunk/generic/ |
Modified ipc_cleanup. |
|
| 1579 |
6724 d 2 h |
jermar |
/kernel/trunk/generic/ |
Framework for task_kill().
Some pieces (e.g. implementation of ktask_cleanup() kernel thread and
task_destroy() function) are missing.
Changed locking order for task lock, threads_lock and thread lock from
threads_lock, thread lock, task lock to task lock, threads_lock, thread lock. |

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

6724 d 7 h |
palkovsky |
/kernel/trunk/generic/ |
Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole. |
|
| 1571 |
6724 d 7 h |
jermar |
/kernel/trunk/generic/ |
thread_join_timeout() and thread_detach() implementation.
Needs more thorough testing. |
|
| 1568 |
6724 d 8 h |
palkovsky |
/kernel/trunk/generic/ |
Slightly remodelled ipc hangups to facilitate correct cleanup.
Doc updates for frame allocator. |
|

6725 d 10 h |

/kernel/trunk/generic/ |
Slightly better behaviour with caching on memory sharing. |
|

6726 d 12 h |
jermar |
/kernel/trunk/ |
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.

Removes unnecessary parameter for map_physmem syscall. |
|
| 1484 |
6727 d 10 h |
palkovsky |
/kernel/trunk/generic/include/ |
Added EINVAL error code. |
|
| 1474 |
6728 d 2 h |
palkovsky |
/kernel/trunk/ |
Added syscall that lets kernel regain access to keyboard. |
|
| 1468 |
6728 d 8 h |

/kernel/trunk/ |
Function for destroying address space for which there is no other reference in the kernel. |
|
| 1461 |
6728 d 10 h |
palkovsky |
/kernel/trunk/generic/ |
Slightly changed semantics of AS_AREA_SEND/RECV. |
|
| 1460 |
6728 d 11 h |
jermar |
/kernel/trunk/generic/ |
Reference counting for futexes. |
|
| 1440 |
6731 d 0 h |
palkovsky |
/kernel/trunk/generic/include/ |
Added error code for timeouts. |
|
| 1438 |
6731 d 2 h |
palkovsky |
/kernel/trunk/generic/ |
Correct realtime clock communication. |
|
| 1434 |
6731 d 6 h |
palkovsky |
/kernel/trunk/ |
Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform. |
|
| 1431 |
6731 d 13 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 |
6731 d 14 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 |
6732 d 1 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. |
|
| 1425 |
6732 d 4 h |
jermar |
/kernel/trunk/generic/ |
Make address space backend data a union. |
|
| 1424 |
6732 d 6 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 |
6732 d 10 h |
jermar |
/kernel/trunk/ |
Update page fault handlers to distinguish between different access modes that had caused the page fault. |
|
| 1417 |
6734 d 3 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 |
6734 d 14 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 |
6734 d 15 h |
jermar |
/kernel/trunk/generic/ |
Some renaming to prevent confusion.
as_lock -> inactive_as_with_asid_lock
as_t::refcount -> as_t::cpu_refcount |
|
| 1413 |
6735 d 2 h |
jermar |
/kernel/trunk/generic/ |
Reimplement memory sharing. Currently, only
anonymous address space areas can be shared. |
|
| 1411 |
6735 d 7 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 |
6736 d 1 h |
jermar |
/kernel/trunk/generic/ |
Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends. |
|
| 1387 |
6738 d 9 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. |
