703 6690 d 2 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
684 6695 d 0 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 6699 d 3 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
614 6721 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 6722 d 4 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6723 d 0 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
575 6724 d 15 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 6725 d 23 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
550 6727 d 18 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
546 6727 d 20 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
534 6729 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6729 d 19 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6741 d 17 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6741 d 20 h decky /kernel/trunk/ preparation for init task loading  
501 6742 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6749 d 16 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6749 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 6756 d 3 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6756 d 3 h decky /SPARTAN/trunk/ new build system almost finished  
455 6756 d 15 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
