860 6670 d 14 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
822 6682 d 15 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 6683 d 1 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
799 6684 d 16 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
789 6685 d 16 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 6687 d 12 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 6689 d 12 h palkovsky /kernel/trunk/ Skeleton of SLAB allocator.  
757 6689 d 17 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 6690 d 14 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 6691 d 13 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 6702 d 15 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6704 d 17 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
703 6709 d 1 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 6713 d 23 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 6718 d 0 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6718 d 16 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6719 d 17 h vana /kernel/trunk/ i8042 bug fix...  
651 6733 d 13 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 6735 d 14 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
628 6737 d 19 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6737 d 21 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 6738 d 3 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 6738 d 22 h palkovsky /kernel/trunk/ better architecture line  
578 6743 d 11 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6745 d 15 h jermar /kernel/trunk/ Send in some improvements.  
562 6745 d 20 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6745 d 20 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6748 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6748 d 18 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6754 d 21 h jermar /kernel/trunk/ Clean up.  
518 6756 d 15 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 6757 d 15 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
512 6760 d 0 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 6760 d 14 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 6760 d 19 h decky /kernel/trunk/ preparation for init task loading  
503 6760 d 21 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).		  
501 6760 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6774 d 12 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.		  
463 6774 d 23 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6774 d 23 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel
