756 6679 d 12 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.		  
755 6680 d 11 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
727 6691 d 14 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6693 d 15 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6697 d 23 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 6702 d 21 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 6706 d 23 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6707 d 14 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6708 d 15 h vana /kernel/trunk/ i8042 bug fix...  
651 6722 d 12 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 6724 d 13 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
628 6726 d 18 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6726 d 20 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 6727 d 2 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 6727 d 21 h palkovsky /kernel/trunk/ better architecture line  
578 6732 d 10 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6734 d 13 h jermar /kernel/trunk/ Send in some improvements.  
562 6734 d 19 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6734 d 19 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6737 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.
