684 6832 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 6832 d 22 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
678 6836 d 15 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6836 d 18 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6836 d 18 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6836 d 23 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6837 d 1 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6837 d 14 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6838 d 15 h vana /kernel/trunk/ i8042 bug fix...  
668 6841 d 21 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 6846 d 11 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6848 d 14 h decky /kernel/trunk/ initial syscall table support  
659 6850 d 1 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6851 d 19 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 6852 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 6852 d 14 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 6853 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 6854 d 13 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6855 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 6856 d 15 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6856 d 17 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6856 d 18 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6856 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 6856 d 21 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6857 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 6857 d 16 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6857 d 21 h palkovsky /kernel/trunk/ better architecture line  
616 6858 d 14 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6859 d 1 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6859 d 11 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 6859 d 18 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6859 d 19 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6859 d 19 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6859 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 6859 d 21 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6860 d 14 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
602 6860 d 15 h palkovsky /kernel/trunk/ Symtab returns correct addresses even when symtab is befor bss.
Some tab completion optimization.		  
601 6860 d 16 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
596 6861 d 12 h jermar /kernel/trunk/ kconsole cleanup.
Separate commands from the engine.		  
594 6861 d 17 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).
