628 6733 d 8 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
627 6733 d 10 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 6733 d 11 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 6733 d 16 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 6734 d 6 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
619 6735 d 1 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 6735 d 4 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
617 6735 d 4 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 6735 d 15 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6736 d 1 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 6736 d 3 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
More ITLB and DTLB controlling functions.
 
612 6736 d 7 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 6736 d 9 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6736 d 9 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6736 d 10 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 6736 d 11 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
605 6736 d 15 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Allow for different ARC frame size and kernel frame size.  
604 6736 d 16 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
602 6737 d 5 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.
 
601 6737 d 7 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.
 
600 6737 d 12 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
599 6737 d 12 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6737 d 13 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
597 6737 d 13 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
595 6738 d 7 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6738 d 7 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
593 6738 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6738 d 9 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 6738 d 10 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
 
586 6738 d 11 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
584 6738 d 11 h jermar /kernel/trunk/arch/ia64/src/ski/ Fix IA-64 ski_getchar().
Output operand vs. input operand.
Now the characters are read correctly.
 
583 6738 d 12 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
581 6738 d 15 h palkovsky /kernel/trunk/ Small debug changes.  
578 6739 d 1 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
577 6739 d 1 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
576 6739 d 2 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
575 6739 d 2 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 6739 d 8 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6739 d 8 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
570 6740 d 4 h jermar /kernel/trunk/arch/sparc64/src/mm/ Missing tlb.c from last commit.
