1060 6688 d 12 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.		  
1053 6688 d 16 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
1050 6688 d 17 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 6688 d 18 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 6688 d 20 h jermar /kernel/trunk/ Page table locking.  
1042 6688 d 20 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6688 d 20 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 6688 d 21 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1032 6689 d 8 h jermar /kernel/trunk/generic/ mmap() syscall.  
1029 6689 d 8 h palkovsky /kernel/trunk/generic/src/ipc/ Fixed bad locking.  
1027 6689 d 8 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1026 6689 d 9 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6689 d 9 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1024 6689 d 14 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1008 6689 d 20 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 6689 d 20 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1005 6689 d 21 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
1002 6690 d 8 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
998 6690 d 9 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
990 6690 d 13 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
983 6690 d 17 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6690 d 18 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6690 d 18 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6690 d 20 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6690 d 23 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
963 6691 d 11 h jermar /kernel/trunk/generic/src/lib/ Fix bug in loading ELF segment.  
959 6691 d 12 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6691 d 12 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.		  
955 6691 d 13 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6691 d 16 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
946 6692 d 10 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
940 6692 d 14 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6692 d 14 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6692 d 15 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
932 6692 d 16 h palkovsky /kernel/trunk/generic/src/console/ Allow using direct address as parameter.  
931 6692 d 16 h palkovsky /kernel/trunk/generic/src/console/ Allow direct address specification.  
910 6699 d 19 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6699 d 22 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
907 6701 d 21 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6702 d 8 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
