1968 6430 d 17 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1963 6430 d 18 h jermar /tags/0.1.1/ Tagging release 0.1.1  
1288 6606 d 3 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.		  
1235 6615 d 3 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.		  
1227 6617 d 23 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.		  
1187 6627 d 22 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.		  
1185 6628 d 0 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6628 d 1 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1178 6628 d 23 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.		  
1176 6629 d 3 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1174 6629 d 5 h jermar /kernel/trunk/ Start capabilities support.  
1171 6629 d 6 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1159 6632 d 0 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1158 6632 d 0 h jermar /kernel/trunk/generic/ Replace list of all threads with B+tree of all threads.
Add function thread_exists() for querying existence of thread.		  
1156 6632 d 1 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().		  
1104 6649 d 22 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1078 6654 d 21 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6655 d 14 h jermar /kernel/trunk/ Support for user space threads.  
1062 6655 d 17 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
1005 6657 d 3 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6657 d 15 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
973 6658 d 3 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
955 6658 d 20 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
906 6669 d 15 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
897 6672 d 15 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
814 6692 d 3 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
788 6694 d 21 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6694 d 22 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
777 6695 d 21 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
775 6696 d 1 h palkovsky /kernel/trunk/generic/ Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.		  
703 6718 d 2 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
678 6726 d 18 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
662 6738 d 16 h decky /kernel/trunk/ initial syscall table support  
623 6747 d 5 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
557 6755 d 2 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.		  
534 6757 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6757 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6770 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6777 d 20 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.		  
475 6782 d 1 h jermar /SPARTAN/trunk/ Define atomic_t type.
