664 6769 d 16 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6771 d 18 h decky /kernel/trunk/ initial syscall table support  
659 6773 d 5 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6774 d 23 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.		  
651 6775 d 16 h decky /kernel/trunk/ remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work)		  
650 6775 d 18 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.		  
646 6776 d 18 h jermar /kernel/trunk/ Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.

sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop.		  
640 6777 d 17 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6778 d 16 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 6779 d 19 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6779 d 21 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6779 d 22 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6780 d 0 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.		  
624 6780 d 1 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6780 d 6 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 6780 d 20 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6781 d 1 h palkovsky /kernel/trunk/ better architecture line  
616 6781 d 18 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6782 d 5 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6782 d 15 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.		  
611 6782 d 22 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6782 d 23 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6783 d 0 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6783 d 0 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 6783 d 1 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6783 d 18 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6783 d 19 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6783 d 21 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
596 6784 d 17 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6784 d 21 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6784 d 23 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6784 d 23 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.		  
589 6784 d 23 h palkovsky /kernel/trunk/generic/src/console/ Added * operator to symbols.  
588 6785 d 0 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 6785 d 0 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
585 6785 d 1 h palkovsky /kernel/trunk/generic/ String constants without spaces are now supported by call commands.
For more we would need some lexer.
The call? commands are not compatibile with stdarg functions on AMD
architectures, because of the calling sequence.		  
582 6785 d 2 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6785 d 4 h palkovsky /kernel/trunk/ Small debug changes.  
579 6785 d 5 h palkovsky /kernel/trunk/generic/src/ Removed unnecessary interrupts_disable from kconsole.
Fixed calling gets() with interrupts_disable.		  
578 6785 d 15 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
