1461 6567 d 22 h palkovsky /kernel/trunk/generic/ Slightly changed semantics of AS_AREA_SEND/RECV.  
1434 6570 d 18 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1428 6571 d 13 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.
 
1417 6573 d 15 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.
 
1413 6574 d 14 h jermar /kernel/trunk/generic/ Reimplement memory sharing. Currently, only
anonymous address space areas can be shared.
 
1396 6577 d 16 h palkovsky /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().
 
1364 6581 d 22 h jermar /kernel/trunk/generic/ Modify ipc_wait_for_call() to support all of blocking, non-blocking and timeout operation.  
1359 6582 d 19 h jermar /kernel/trunk/generic/ Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.  
1346 6583 d 2 h palkovsky /kernel/trunk/generic/src/ipc/ Small updates to IPC regarding AS_SEND.  
1342 6583 d 3 h jermar /kernel/trunk/generic/ Improve comments.  
1329 6584 d 19 h palkovsky /kernel/trunk/generic/ Added support to IPC for simple page sharing.  
1297 6591 d 21 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1293 6593 d 21 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6594 d 0 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.
 
1284 6596 d 4 h palkovsky /kernel/trunk/generic/ Added commands for accessing ia32 portspace in irq top-half.  
1281 6596 d 15 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1260 6599 d 14 h palkovsky /kernel/trunk/ Small fixes.  
1258 6599 d 14 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.
 
1248 6601 d 19 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1223 6606 d 0 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1141 6628 d 22 h palkovsky /kernel/trunk/generic/src/ipc/ Completed ipc_cleanup, it should be somehow integrated into
cleanup of task. The function can sleep.
 
1090 6640 d 17 h palkovsky /kernel/trunk/generic/ Reduced unnecessary IPC system calls.
Allow everything to be sync & async, everything is handled using messages.
 
1088 6641 d 0 h palkovsky /kernel/trunk/generic/ More IPC stuff, added correct closing of connections from both sides.  
1086 6641 d 13 h palkovsky /kernel/trunk/generic/ Untested better IPC functions.
* There is some bug in MIPS, unpredicatbly sometimes the thread gets mapped
different frame for stack.
 
1084 6642 d 11 h palkovsky /kernel/trunk/ Better IPC implementation with regard to locking and final cleanup.  
1083 6642 d 13 h palkovsky /kernel/trunk/generic/src/ Fixed incorrect locking in ipc.  
1072 6643 d 1 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1063 6643 d 12 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1060 6643 d 15 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.
 
1050 6643 d 20 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1040 6644 d 0 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.
 
1029 6644 d 12 h palkovsky /kernel/trunk/generic/src/ipc/ Fixed bad locking.  
1027 6644 d 12 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1005 6645 d 1 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
998 6645 d 13 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
980 6645 d 22 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.
 
965 6646 d 3 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.
 
959 6646 d 16 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
955 6646 d 17 h palkovsky /kernel/trunk/ Added kernel IPC functionality.
