703 6741 d 7 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().		  
684 6746 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.		  
675 6750 d 6 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6750 d 22 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6751 d 23 h vana /kernel/trunk/ i8042 bug fix...  
654 6765 d 2 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 6765 d 19 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)		  
640 6767 d 20 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
629 6770 d 0 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6770 d 1 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6770 d 3 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.		  
623 6770 d 9 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.		  
621 6771 d 4 h palkovsky /kernel/trunk/ better architecture line  
615 6772 d 8 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6773 d 2 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6775 d 18 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6777 d 21 h jermar /kernel/trunk/ Send in some improvements.  
562 6778 d 2 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6778 d 2 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6781 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
