703 6762 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 6767 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 6771 d 19 h jermar /kernel/trunk/generic/src/ Clean up.  
673 6772 d 10 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
671 6773 d 11 h vana /kernel/trunk/ i8042 bug fix...  
654 6786 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 6787 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 6789 d 9 h jermar /kernel/trunk/ sparc64 work.
CPU identification.
 
629 6791 d 12 h decky /kernel/trunk/ init task loading (yet buggy)  
628 6791 d 14 h decky /kernel/trunk/ ia32: floppy boot image uses GRUB  
625 6791 d 16 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 6791 d 22 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 6792 d 17 h palkovsky /kernel/trunk/ better architecture line  
615 6793 d 21 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6794 d 15 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6797 d 6 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
564 6799 d 9 h jermar /kernel/trunk/ Send in some improvements.  
562 6799 d 15 h decky /kernel/trunk/generic/src/main/ fix typo  
561 6799 d 15 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
534 6802 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6802 d 13 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6808 d 16 h jermar /kernel/trunk/ Clean up.  
518 6810 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 6811 d 9 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.
 
512 6813 d 19 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 6814 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 6814 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 6814 d 13 h decky /kernel/trunk/ preparation for init task loading  
503 6814 d 16 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 6814 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
470 6828 d 7 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 6828 d 17 h decky /SPARTAN/trunk/ even fancier release/revision display  
462 6828 d 18 h decky /SPARTAN/trunk/ include svn revision and build time in the kernel  
460 6828 d 19 h decky /SPARTAN/trunk/ some fancy stuff  
459 6828 d 19 h decky /SPARTAN/trunk/ build system: CONFIG_TEST, CONFIG_USERSPACE  
458 6828 d 20 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6829 d 12 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
430 6835 d 10 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6849 d 22 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
 
413 6850 d 8 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
