664 6852 d 19 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6854 d 21 h decky /kernel/trunk/ initial syscall table support  
659 6856 d 9 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6858 d 2 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 6858 d 20 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 6858 d 21 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 6859 d 21 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 6860 d 21 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6861 d 20 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 6862 d 23 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6863 d 1 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6863 d 2 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6863 d 4 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 6863 d 5 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6863 d 10 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 6864 d 0 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6864 d 5 h palkovsky /kernel/trunk/ better architecture line  
616 6864 d 22 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6865 d 9 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6865 d 19 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 6866 d 1 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6866 d 3 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6866 d 3 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6866 d 4 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 6866 d 5 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6866 d 21 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6866 d 23 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6867 d 0 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
597 6867 d 7 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
596 6867 d 20 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6868 d 1 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6868 d 2 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6868 d 2 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 6868 d 3 h palkovsky /kernel/trunk/generic/src/console/ Added * operator to symbols.  
588 6868 d 4 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		  
587 6868 d 4 h jermar /kernel/trunk/ Nasty hack for ppc32.
Main Makefile now passes -D$(ARCH) so that it is possible to have ugly architectural #ifdefs.		  
586 6868 d 4 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
585 6868 d 4 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 6868 d 5 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6868 d 8 h palkovsky /kernel/trunk/ Small debug changes.
