727 6743 d 1 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
724 6745 d 2 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
718 6747 d 2 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 6747 d 5 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
703 6749 d 10 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 6754 d 8 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 6758 d 10 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6759 d 1 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
671 6760 d 2 h vana /kernel/trunk/ i8042 bug fix...  
654 6773 d 6 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 6773 d 23 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 6776 d 0 h jermar /kernel/trunk/ sparc64 work.
CPU identification.		  
629 6778 d 4 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6778 d 5 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6778 d 7 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 6778 d 13 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 6779 d 8 h palkovsky /kernel/trunk/ better architecture line  
615 6780 d 12 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6781 d 6 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6783 d 21 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
564 6786 d 0 h jermar /kernel/trunk/ Send in some improvements.  
562 6786 d 6 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6786 d 6 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6789 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6789 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6795 d 7 h jermar /kernel/trunk/ Clean up.  
518 6797 d 1 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 6798 d 0 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
512 6800 d 10 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 6801 d 0 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 6801 d 2 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 6801 d 5 h decky /kernel/trunk/ preparation for init task loading  
503 6801 d 7 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 6801 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6814 d 22 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 6815 d 9 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6815 d 9 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6815 d 10 h decky /SPARTAN/trunk/ some fancy stuff  
459 6815 d 11 h decky /SPARTAN/trunk/ build system: CONFIG_TEST, CONFIG_USERSPACE  
458 6815 d 11 h decky /SPARTAN/trunk/ make configuration variables usage consistent
