1104 6624 d 23 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1100 6626 d 19 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
1077 6630 d 2 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1072 6630 d 4 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 6630 d 6 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1064 6630 d 15 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6630 d 16 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1051 6630 d 23 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6631 d 0 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.		  
1024 6631 d 21 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1021 6631 d 22 h jermar /kernel/trunk/ Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time.		  
984 6633 d 0 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6633 d 2 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6633 d 5 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6633 d 19 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6633 d 20 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 6633 d 20 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
940 6634 d 21 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6634 d 21 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6642 d 2 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.
