1780 7197 d 7 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 7211 d 12 h jermar /kernel/trunk/ Cleanup of comments.  
1735 7213 d 14 h decky /kernel/trunk/ make kernel prints case consistent  
1702 7218 d 10 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1687 7221 d 11 h jermar /kernel/trunk/generic/src/proc/ Fix double thread_join() in ktaskgc.
In thread_create(), lock TASK with interrupts disabled again.
thread_join_timeout() can use ordinary waitq_sleep_timeout().		  
1684 7221 d 14 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1676 7222 d 11 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1661 7223 d 15 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1636 7225 d 0 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1600 7225 d 16 h jermar /kernel/trunk/generic/src/proc/ Prevent task killing of kernel by returning EPERM on such a request.  
1597 7225 d 16 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1589 7226 d 6 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 7226 d 6 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().		  
1587 7226 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.		  
1585 7226 d 10 h jermar /kernel/trunk/generic/ Kill task when its main thread exits.  
1583 7226 d 13 h jermar /kernel/trunk/generic/ Make ktaskclnp call ipc_cleanup and futex_cleanup.  
1580 7226 d 17 h jermar /kernel/trunk/generic/src/ Update for task_kill().  
1579 7227 d 3 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.		  
1573 7227 d 7 h palkovsky /kernel/trunk/generic/ Renamed some things in IPC to be consistent.
Added ipc reporting to kconsole.		  
1468 7231 d 8 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1460 7231 d 12 h jermar /kernel/trunk/generic/ Reference counting for futexes.  
1424 7235 d 7 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.		  
1409 7239 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.		  
1358 7246 d 7 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 7257 d 12 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1248 7265 d 7 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 7266 d 6 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.		  
1235 7266 d 13 h jermar /kernel/trunk/generic/ Implementation of SYS_AS_AREA_ACCEPT and SYS_AS_AREA_SEND syscalls.
Note that these replace previously declared SYS_AS_AREA_SHARE_APPROVE
and SYS_AS_AREA_SHARE_PERFORM.		  
1229 7268 d 11 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1227 7269 d 8 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1196 7276 d 11 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1185 7279 d 10 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1178 7280 d 8 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1177 7280 d 12 h jermar /kernel/trunk/generic/ Modify B+tree node key width to be 64-bit wide on all platforms.  
1176 7280 d 12 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1174 7280 d 14 h jermar /kernel/trunk/ Start capabilities support.  
1170 7281 d 8 h vana /kernel/trunk/ Stack size definition macro definition fix  
1168 7283 d 5 h vana /kernel/trunk/ Thread RSE support completion (kernel)  
1159 7283 d 9 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1115 7300 d 13 h jermar /kernel/trunk/generic/src/proc/ Fix kcpulb() to change state of the migrated thread to Entering so that thread_ready() won't panic() on violated assertion.
Make print out of threads and tasks more dense again.
