686 6720 d 21 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6720 d 21 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
683 6720 d 21 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
678 6724 d 15 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6724 d 17 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6724 d 18 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6724 d 23 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6725 d 0 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6725 d 14 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6726 d 15 h vana /kernel/trunk/ i8042 bug fix...  
668 6729 d 20 h bondari /kernel/trunk/generic/src/console/ Zones related commands infrastructure for console. Also fixed small bug that caused infinite loop during command parsing  
664 6734 d 11 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6736 d 13 h decky /kernel/trunk/ initial syscall table support  
659 6738 d 1 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6739 d 18 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 6740 d 12 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 6740 d 13 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 6741 d 13 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 6742 d 13 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6743 d 12 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 6744 d 15 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6744 d 17 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6744 d 18 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6744 d 20 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 6744 d 21 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6745 d 2 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 6745 d 16 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6745 d 21 h palkovsky /kernel/trunk/ better architecture line  
616 6746 d 14 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6747 d 1 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6747 d 10 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 6747 d 17 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6747 d 19 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6747 d 19 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6747 d 20 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 6747 d 20 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6748 d 13 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6748 d 15 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6748 d 16 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
596 6749 d 12 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.
