662 6767 d 1 h decky /kernel/trunk/ initial syscall table support  
659 6768 d 13 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6770 d 6 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 6770 d 23 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 6771 d 1 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 6772 d 1 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 6773 d 0 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6774 d 0 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 6775 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6775 d 4 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6775 d 6 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6775 d 8 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 6775 d 8 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6775 d 13 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 6776 d 3 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6776 d 9 h palkovsky /kernel/trunk/ better architecture line  
616 6777 d 1 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6777 d 12 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6777 d 22 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 6778 d 5 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6778 d 6 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6778 d 7 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6778 d 7 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 6778 d 8 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6779 d 1 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6779 d 2 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6779 d 4 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
597 6779 d 10 h jermar /kernel/trunk/ Finer grained TLB invalidate functions for ia32 and amd64. Not yet deployed.  
596 6780 d 0 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6780 d 5 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
591 6780 d 6 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
590 6780 d 6 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 6780 d 7 h palkovsky /kernel/trunk/generic/src/console/ Added * operator to symbols.  
588 6780 d 7 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 6780 d 7 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 6780 d 8 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.		  
585 6780 d 8 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 6780 d 9 h palkovsky /kernel/trunk/generic/ Added calling of generic functions to kconsole.  
581 6780 d 12 h palkovsky /kernel/trunk/ Small debug changes.  
579 6780 d 12 h palkovsky /kernel/trunk/generic/src/ Removed unnecessary interrupts_disable from kconsole.
Fixed calling gets() with interrupts_disable.
