1101 6809 d 22 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.		  
1063 6813 d 18 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6813 d 20 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 6814 d 7 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
955 6816 d 22 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
860 6837 d 18 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
822 6849 d 19 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 6850 d 6 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
799 6851 d 21 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
789 6852 d 20 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 6854 d 16 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 6856 d 16 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6856 d 21 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 6857 d 18 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 6858 d 17 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 6869 d 20 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6871 d 21 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6876 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 6881 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 6885 d 5 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6885 d 20 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6886 d 21 h vana /kernel/trunk/ i8042 bug fix...  
651 6900 d 18 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 6902 d 19 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
628 6905 d 0 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6905 d 2 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 6905 d 8 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 6906 d 3 h palkovsky /kernel/trunk/ better architecture line  
578 6910 d 16 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6912 d 19 h jermar /kernel/trunk/ Send in some improvements.  
562 6913 d 1 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6913 d 1 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6915 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6915 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6922 d 2 h jermar /kernel/trunk/ Clean up.  
518 6923 d 19 h jermar /kernel/trunk/ Improve kconsole's support for recognition of commands with arguments.
Implement ARG_TYPE_STRING.
Add 'describe' command.
Move kconsole.c to generic/src/console.
Move kconsole.h to generic/include/console.		  
517 6924 d 19 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
512 6927 d 5 h jermar /kernel/trunk/ SMP work.
Add madt_irq_to_pin().
Make ksmp() use virtual irq_to_pin() function, which makes better sence for ACPI configurations.		  
510 6927 d 18 h jermar /kernel/trunk/ Add chardev_t.
This type is meant to abstract any input character device such as keyboard, serial port etc.
Add stdin.
Add dummy kconsole.		  
506 6927 d 23 h decky /kernel/trunk/ preparation for init task loading
