699 6741 d 2 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6742 d 23 h bondari /kernel/trunk/ Frame alloc test #1  
687 6742 d 23 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6743 d 0 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6743 d 1 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 6743 d 1 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
678 6746 d 19 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6746 d 21 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6746 d 21 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6747 d 2 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6747 d 4 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6747 d 18 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6748 d 19 h vana /kernel/trunk/ i8042 bug fix...  
668 6752 d 0 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 6756 d 15 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6758 d 17 h decky /kernel/trunk/ initial syscall table support  
659 6760 d 5 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6761 d 22 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 6762 d 15 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 6762 d 17 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 6763 d 17 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 6764 d 16 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6765 d 16 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 6766 d 18 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6766 d 20 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6766 d 21 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6767 d 0 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 6767 d 0 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6767 d 5 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 6767 d 19 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6768 d 1 h palkovsky /kernel/trunk/ better architecture line  
616 6768 d 17 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6769 d 4 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6769 d 14 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 6769 d 21 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6769 d 22 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6769 d 23 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6769 d 23 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 6770 d 0 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.		  
603 6770 d 17 h palkovsky /kernel/trunk/generic/src/ Added set4 command.
