1048 6656 d 13 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.

1040 6656 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 6656 d 16 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1032 6657 d 3 h jermar /kernel/trunk/generic/ mmap() syscall.  
1027 6657 d 3 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
1026 6657 d 4 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
1005 6657 d 16 h palkovsky /kernel/trunk/generic/ Added support for taskid.  
1002 6658 d 3 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
998 6658 d 4 h palkovsky /kernel/trunk/generic/ Completed asynchronous ipc.  
980 6658 d 13 h palkovsky /kernel/trunk/ Small speed update of ipc.
Fixed some bugs regarding pages in mremap.		  
977 6658 d 13 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
973 6658 d 15 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6658 d 18 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
959 6659 d 7 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6659 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 6659 d 8 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6659 d 11 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
946 6660 d 5 h jermar /kernel/trunk/generic/ Fix frame deallocation.
Zone state is to be upadated only when the frame refcount reaches zero.		  
940 6660 d 9 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6660 d 9 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
935 6660 d 10 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
910 6667 d 14 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6667 d 17 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
906 6670 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		  
897 6673 d 4 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.		  
880 6674 d 17 h jermar /kernel/trunk/generic/include/mm/ Fix conflict between asid_get() macro and function definitions.  
878 6675 d 14 h vana /kernel/trunk/ Active keyboard read for ia32  
869 6678 d 4 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
866 6678 d 16 h jermar /kernel/trunk/generic/include/ Remove nasty ppc32 hack.
ppc32 now uses the stock ALIGN_UP().		  
856 6681 d 7 h bondari /kernel/trunk/generic/include/  
855 6681 d 9 h bondari /kernel/trunk/generic/include/ ELF section definition  
854 6681 d 9 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
837 6686 d 17 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.

830 6690 d 13 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().		  
827 6691 d 4 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
826 6691 d 6 h jermar /kernel/trunk/ Add page_mapping_remove().  
823 6692 d 4 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.

recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
