703 6742 d 11 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
701 6745 d 1 h jermar /kernel/trunk/generic/src/mm/ Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.
 
699 6745 d 10 h jermar /kernel/trunk/ Memory management work.
Proto-interface and dummy implementation of generic page hash table subsytem.
 
689 6747 d 7 h bondari /kernel/trunk/ Frame alloc test #1  
687 6747 d 7 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
686 6747 d 9 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
684 6747 d 9 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 6747 d 9 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
 
681 6747 d 12 h jermar /kernel/trunk/ Minor changes.  
678 6751 d 3 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
677 6751 d 5 h bondari /kernel/trunk/generic/src/ Comments to zone console commands  
676 6751 d 5 h bondari /kernel/trunk/generic/ Memory zones console command implementation. todo: buddy allocator structures.  
675 6751 d 11 h jermar /kernel/trunk/generic/src/ Clean up.  
674 6751 d 12 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6752 d 2 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
671 6753 d 3 h vana /kernel/trunk/ i8042 bug fix...  
669 6756 d 1 h jermar /kernel/trunk/ sparc64 work.
kconsole support.
Add non-blocking ofw_getchar().
 
668 6756 d 8 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 6760 d 23 h jermar /kernel/trunk/ sparc64 work.
Interrupt Levels 1 - 15 serviced.
Minor changes in the exc_* functions.
 
662 6763 d 1 h decky /kernel/trunk/ initial syscall table support  
659 6764 d 13 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
654 6766 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 6766 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 6767 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 6768 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 6769 d 0 h jermar /kernel/trunk/ sparc64 work.
CPU identification.
 
635 6770 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 6771 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
629 6771 d 4 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6771 d 6 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6771 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 6771 d 8 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6771 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 6772 d 3 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
621 6772 d 9 h palkovsky /kernel/trunk/ better architecture line  
616 6773 d 1 h palkovsky /kernel/trunk/generic/src/debug/ Symtab completion now completes even * and & symbols.  
615 6773 d 12 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6773 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 6774 d 5 h jermar /kernel/trunk/generic/src/console/ Fix kconsole so that side-effect command shortcuts do not take effect.  
609 6774 d 6 h palkovsky /kernel/trunk/ added support for breakpoints to mips32
