1164 6625 d 11 h jermar /kernel/trunk/generic/ Switch B+tree node allocation from malloc() to a dedicated slab - btree_node_slab.  
1138 6638 d 11 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 6643 d 6 h jermar /kernel/trunk/ Basic futex. Prototype implementation.  
1101 6645 d 7 h jermar /kernel/trunk/ B+-tree implementation.
Currently supports only inserting and searching.		  
1063 6649 d 4 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1062 6649 d 5 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 6649 d 16 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
955 6652 d 8 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
860 6673 d 4 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
822 6685 d 5 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 6685 d 15 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
799 6687 d 7 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
789 6688 d 6 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 6690 d 2 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 6692 d 2 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6692 d 7 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 6693 d 4 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 6694 d 3 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 6705 d 6 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6707 d 7 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6711 d 15 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 6716 d 13 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 6720 d 15 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6721 d 6 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6722 d 7 h vana /kernel/trunk/ i8042 bug fix...  
651 6736 d 3 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 6738 d 5 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
628 6740 d 10 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6740 d 12 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 6740 d 18 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 6741 d 13 h palkovsky /kernel/trunk/ better architecture line  
578 6746 d 2 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6748 d 5 h jermar /kernel/trunk/ Send in some improvements.  
562 6748 d 11 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6748 d 11 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6751 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6751 d 9 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6757 d 12 h jermar /kernel/trunk/ Clean up.  
518 6759 d 5 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 6760 d 5 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
