1048 6651 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 6651 d 14 h jermar /kernel/trunk/ Page table locking.  
1042 6651 d 14 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6651 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 6651 d 15 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1032 6652 d 2 h jermar /kernel/trunk/generic/ mmap() syscall.  
1029 6652 d 2 h palkovsky /kernel/trunk/generic/src/ipc/ Fixed bad locking.  
1027 6652 d 2 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1026 6652 d 3 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1025 6652 d 4 h palkovsky /kernel/trunk/generic/src/proc/ Fix bug that made task_run_program to always run init.  
1024 6652 d 8 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1008 6652 d 14 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 6652 d 15 h decky /kernel/trunk/ ppc32: preemptive scheduling works now
FPU context saving disabled for now		  
1005 6652 d 15 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
1002 6653 d 2 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
998 6653 d 3 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
990 6653 d 8 h decky /kernel/trunk/ ppc32: initial stack, memory barriers, atomic operations, stack offset fix  
983 6653 d 12 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
980 6653 d 12 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6653 d 13 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6653 d 15 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6653 d 17 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
963 6654 d 5 h jermar /kernel/trunk/generic/src/lib/ Fix bug in loading ELF segment.  
959 6654 d 6 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6654 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.		  
955 6654 d 7 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6654 d 11 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
946 6655 d 5 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
938 6655 d 8 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6655 d 9 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
932 6655 d 10 h palkovsky /kernel/trunk/generic/src/console/ Allow using direct address as parameter.  
931 6655 d 10 h palkovsky /kernel/trunk/generic/src/console/ Allow direct address specification.  
910 6662 d 13 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
907 6664 d 15 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6665 d 3 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		  
902 6666 d 14 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.

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.		  
882 6669 d 15 h jermar /kernel/trunk/generic/src/lib/ Improved version of generic memcpy().
