689 6734 d 17 h bondari /kernel/trunk/ Frame alloc test #1  
687 6734 d 17 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
684 6734 d 19 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 6738 d 22 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6739 d 12 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
655 6753 d 16 h jermar /kernel/trunk/arch/ Compilation fixes.  
635 6757 d 10 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 6758 d 12 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
627 6758 d 17 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 6758 d 18 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 6758 d 23 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 6759 d 13 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
618 6760 d 11 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
615 6760 d 23 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6761 d 8 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 6761 d 14 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 6761 d 16 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6761 d 17 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6761 d 17 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 6761 d 18 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
605 6761 d 22 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Allow for different ARC frame size and kernel frame size.  
604 6761 d 23 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6762 d 19 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
599 6762 d 19 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6762 d 20 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6763 d 14 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6763 d 15 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
593 6763 d 16 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6763 d 16 h palkovsky /kernel/trunk/ Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned.
 
588 6763 d 17 h palkovsky /kernel/trunk/ Added support for backspace
- printing '\b' should move the cursor one char to the left
- backspace key should return '\b' to application
 
581 6763 d 22 h palkovsky /kernel/trunk/ Small debug changes.  
578 6764 d 8 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
577 6764 d 8 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
575 6764 d 10 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.
 
574 6764 d 15 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6764 d 15 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6765 d 11 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
568 6765 d 18 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
567 6766 d 9 h palkovsky /kernel/trunk/ Added simple support for arc keyboards on mips.  
550 6767 d 13 h palkovsky /kernel/trunk/ Completely reworked configuration system.
