689 6696 d 21 h bondari /kernel/trunk/ Frame alloc test #1  
687 6696 d 21 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
684 6696 d 22 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 6701 d 2 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6701 d 15 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
655 6715 d 19 h jermar /kernel/trunk/arch/ Compilation fixes.  
635 6719 d 13 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.		  
631 6720 d 16 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
627 6720 d 20 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 6720 d 21 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 6721 d 3 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 6721 d 17 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
618 6722 d 14 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
615 6723 d 2 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6723 d 12 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.		  
612 6723 d 18 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 6723 d 20 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6723 d 20 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6723 d 21 h palkovsky /kernel/trunk/ Fixed weird simics panic.
Run kconsole, if we panic. This currently works in gxemul,
simics. In mips we need to modify the simulator.
On ia32 we need a function, that would speak directly to the chip
and fetch the character using polling.		  
606 6723 d 22 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
