684 6742 d 23 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 6747 d 3 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6769 d 13 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 6770 d 3 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6770 d 23 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
575 6772 d 14 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 6773 d 22 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6775 d 18 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6775 d 20 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6777 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6777 d 19 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6789 d 17 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6789 d 20 h decky /kernel/trunk/ preparation for init task loading  
501 6789 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6797 d 16 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6797 d 19 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 6804 d 2 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6804 d 2 h decky /SPARTAN/trunk/ new build system almost finished  
455 6804 d 14 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
431 6809 d 2 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
