684 6758 d 3 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
674 6762 d 7 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6784 d 17 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.
 
604 6785 d 7 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6786 d 3 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
575 6787 d 18 h palkovsky /kernel/trunk/ Added generic exc_register/exc_dispatch functions,
copied from ia32 architecture. Currently only mips32 uses them.

The chardev_t can now be both input & output device (was
needed for serial driver).

Broken other architectures - ia64, sparc, powerpc will not compile.

Mips32 supports input on all msim, gxemul, indy(tested emulation
in gxemul, loses characters), simics. Simics serial line
is done using polling, I was unable to make it produce
an interrupt when the key was pressed.
 
568 6789 d 2 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6790 d 21 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6791 d 0 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6792 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6792 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6804 d 21 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6805 d 0 h decky /kernel/trunk/ preparation for init task loading  
501 6805 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6812 d 20 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6812 d 23 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
458 6819 d 6 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6819 d 6 h decky /SPARTAN/trunk/ new build system almost finished  
455 6819 d 18 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
431 6824 d 6 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
