727 6740 d 9 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6742 d 11 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6744 d 10 h decky /kernel/trunk/ interface change: as_area_load_mapping -> as_area_set_mapping (set single page mapping)
map init directly from the physical frames it is loaded in		  
717 6744 d 13 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
703 6746 d 19 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 6751 d 17 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 6755 d 18 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6756 d 10 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6757 d 11 h vana /kernel/trunk/ i8042 bug fix...  
654 6770 d 14 h jermar /kernel/trunk/generic/src/ Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's.		  
651 6771 d 7 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 6773 d 8 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
629 6775 d 12 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6775 d 13 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6775 d 15 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 6775 d 21 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 6776 d 16 h palkovsky /kernel/trunk/ better architecture line  
615 6777 d 20 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6778 d 14 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6781 d 5 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6783 d 9 h jermar /kernel/trunk/ Send in some improvements.  
562 6783 d 14 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6783 d 14 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6786 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6786 d 12 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6792 d 15 h jermar /kernel/trunk/ Clean up.  
518 6794 d 9 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 6795 d 9 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
512 6797 d 18 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 6798 d 8 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.		  
508 6798 d 11 h jermar /kernel/trunk/ Basic keyboard support for ia32.
For some reason, keyoboard looks dead on SMP.

Make kinit() print "kinit..." strings in longer intervals.		  
506 6798 d 13 h decky /kernel/trunk/ preparation for init task loading  
503 6798 d 15 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 6798 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6812 d 6 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 6812 d 17 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6812 d 17 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6812 d 19 h decky /SPARTAN/trunk/ some fancy stuff  
459 6812 d 19 h decky /SPARTAN/trunk/ build system: CONFIG_TEST, CONFIG_USERSPACE  
458 6812 d 19 h decky /SPARTAN/trunk/ make configuration variables usage consistent
