fix page hash table refill logic		  
1315 6670 d 22 h jermar /kernel/trunk/generic/ Improve framebuffer speed by buffering blank line.  
1248 6686 d 22 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6690 d 3 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.		  
1224 6691 d 1 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1221 6691 d 17 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6698 d 2 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1164 6704 d 23 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1138 6717 d 23 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().		  
1109 6722 d 17 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1101 6724 d 19 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.		  
1063 6728 d 16 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6728 d 17 h jermar /kernel/trunk/ It is now possible to associate symbolic names with both threads and tasks.
More verbose kconsole threads, tasks and scheduler commands.		  
1037 6729 d 4 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
955 6731 d 20 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
860 6752 d 16 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
822 6764 d 17 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
814 6765 d 3 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
799 6766 d 18 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
789 6767 d 18 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
773 6769 d 14 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.		  
759 6771 d 14 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6771 d 19 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.		  
756 6772 d 16 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 6773 d 15 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 6784 d 17 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6786 d 19 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6791 d 3 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 6796 d 1 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 6800 d 2 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6800 d 18 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6801 d 19 h vana /kernel/trunk/ i8042 bug fix...  
651 6815 d 15 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 6817 d 16 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
628 6819 d 21 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6820 d 0 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 6820 d 5 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 6821 d 1 h palkovsky /kernel/trunk/ better architecture line  
578 6825 d 14 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6827 d 17 h jermar /kernel/trunk/ Send in some improvements.
