1358 6601 d 3 h jermar /kernel/trunk/generic/ Cleanup after removal of as_area_accept and as_area_send.  
1288 6612 d 8 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 6621 d 8 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 6624 d 4 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 6634 d 2 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 6634 d 5 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6634 d 5 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 6635 d 3 h jermar /kernel/trunk/ Add task_find_by_id().
Add kernel support for SYS_MAP_PHYSMEM.
 
1176 6635 d 8 h jermar /kernel/trunk/generic/ Kernel support for SYS_GET_TASK_ID syscall.  
1174 6635 d 9 h jermar /kernel/trunk/ Start capabilities support.  
1171 6635 d 11 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1159 6638 d 4 h jermar /kernel/trunk/generic/ Replace list of all tasks with B+tree of all tasks.  
1158 6638 d 5 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 6638 d 6 h jermar /kernel/trunk/generic/ Sleeping in a wait queue can be now interrupted with
waitq_interrupt_sleep().
 
1104 6656 d 2 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 6661 d 2 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1066 6661 d 18 h jermar /kernel/trunk/ Support for user space threads.  
1062 6661 d 21 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 6663 d 8 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6663 d 20 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
973 6664 d 8 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
955 6665 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
906 6675 d 19 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 6678 d 20 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 6698 d 7 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
788 6701 d 2 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6701 d 3 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
777 6702 d 2 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
775 6702 d 6 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 6724 d 7 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 6732 d 23 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
662 6744 d 21 h decky /kernel/trunk/ initial syscall table support  
623 6753 d 9 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 6761 d 6 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
534 6764 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6764 d 0 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6776 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6784 d 0 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 6788 d 6 h jermar /SPARTAN/trunk/ Define atomic_t type.  
452 6791 d 0 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
