1072 6638 d 16 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.		  
1070 6638 d 17 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1069 6638 d 17 h cejka /kernel/trunk/ Printf correctly handle NULL pointer as parameter to %s option.  
1066 6639 d 2 h jermar /kernel/trunk/ Support for user space threads.  
1063 6639 d 3 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6639 d 5 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.		  
1060 6639 d 6 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.		  
1053 6639 d 10 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1050 6639 d 11 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.		  
1048 6639 d 12 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1044 6639 d 14 h jermar /kernel/trunk/ Page table locking.  
1042 6639 d 15 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6639 d 15 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.		  
1037 6639 d 16 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1032 6640 d 3 h jermar /kernel/trunk/generic/ mmap() syscall.  
1029 6640 d 3 h palkovsky /kernel/trunk/generic/src/ipc/ Fixed bad locking.  
1027 6640 d 3 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1026 6640 d 3 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6640 d 4 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1024 6640 d 8 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1008 6640 d 15 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.		  
1007 6640 d 15 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1005 6640 d 15 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
1002 6641 d 2 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
998 6641 d 3 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
990 6641 d 8 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
983 6641 d 12 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6641 d 13 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6641 d 13 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6641 d 15 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6641 d 18 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.

Widened syscall to support up to 5 parameters.		  
958 6642 d 7 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
