664 6759 d 6 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6761 d 8 h decky /kernel/trunk/ initial syscall table support  
659 6762 d 20 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6764 d 13 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 6765 d 6 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 6765 d 8 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 6766 d 8 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 6767 d 7 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6768 d 7 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 6769 d 9 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6769 d 11 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6769 d 13 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6769 d 15 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 6769 d 15 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6769 d 20 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 6770 d 10 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6770 d 16 h palkovsky /kernel/trunk/ better architecture line  
616 6771 d 8 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6771 d 20 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6772 d 5 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 6772 d 12 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6772 d 14 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6772 d 14 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6772 d 14 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 6772 d 15 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6773 d 8 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6773 d 9 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6773 d 11 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
597 6773 d 17 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
596 6774 d 7 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6774 d 12 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6774 d 13 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6774 d 13 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 6774 d 14 h palkovsky /kernel/trunk/generic/src/console/ Added * operator to symbols.  
588 6774 d 14 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 6774 d 14 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 6774 d 15 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
585 6774 d 15 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 6774 d 16 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6774 d 19 h palkovsky /kernel/trunk/ Small debug changes.
