703 6747 d 5 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 6752 d 3 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 6756 d 4 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6756 d 20 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6757 d 21 h vana /kernel/trunk/ i8042 bug fix...  
654 6771 d 0 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 6771 d 17 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 6773 d 18 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
629 6775 d 22 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6775 d 23 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6776 d 1 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 6776 d 7 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 6777 d 2 h palkovsky /kernel/trunk/ better architecture line  
615 6778 d 6 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6779 d 0 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6781 d 15 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6783 d 19 h jermar /kernel/trunk/ Send in some improvements.  
562 6784 d 0 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6784 d 0 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6786 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
