699 6730 d 7 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.		  
689 6732 d 4 h bondari /kernel/trunk/ Frame alloc test #1  
687 6732 d 4 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.		  
686 6732 d 5 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6732 d 5 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 6732 d 6 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.		  
681 6732 d 8 h jermar /kernel/trunk/ Minor changes.  
678 6735 d 23 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6736 d 2 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6736 d 2 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6736 d 7 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6736 d 9 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6736 d 22 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6737 d 23 h vana /kernel/trunk/ i8042 bug fix...  
669 6740 d 22 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().		  
668 6741 d 5 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 6745 d 19 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.		  
662 6747 d 22 h decky /kernel/trunk/ initial syscall table support  
659 6749 d 9 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6751 d 3 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 6751 d 20 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 6751 d 22 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 6752 d 21 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 6753 d 21 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
635 6754 d 20 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 6755 d 23 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6756 d 1 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6756 d 2 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6756 d 4 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 6756 d 5 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6756 d 10 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 6757 d 0 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6757 d 5 h palkovsky /kernel/trunk/ better architecture line  
616 6757 d 22 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6758 d 9 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6758 d 19 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 6759 d 2 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6759 d 3 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
608 6759 d 4 h palkovsky /kernel/trunk/generic/src/console/ intelligent retyping for set4  
607 6759 d 4 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.
