635 6714 d 19 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.		  
634 6715 d 8 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Better way of trap table organization.
Kernel trap handlers now "stay" on addresses on wich they were linked.		  
633 6715 d 21 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.  
632 6715 d 21 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add trap_install_handler().
Use trap_install_handler() to install register window clean, spill and fill handlers.		  
631 6715 d 22 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
630 6715 d 23 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Register window clean, spill and fill handlers.		  
629 6716 d 0 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6716 d 1 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
627 6716 d 2 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.		  
625 6716 d 3 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
623 6716 d 9 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.		  
622 6716 d 23 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
619 6717 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.		  
618 6717 d 20 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
617 6717 d 20 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid).		  
615 6718 d 8 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6718 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.		  
613 6718 d 19 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
More ITLB and DTLB controlling functions.		  
612 6718 d 23 h jermar /kernel/trunk/arch/mips32/src/mm/ Weaken the assumption, that PageMask register contains the right mask everytime.
As a result, TLB exceptions will explicitly write this register when filling TLB entry.
Adjust tlb_print() on mips32 to print PageMask as well.		  
610 6719 d 1 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.
