1248 6594 d 8 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1196 6605 d 12 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1174 6609 d 15 h jermar /kernel/trunk/ Start capabilities support.  
1062 6636 d 3 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.		  
1042 6636 d 13 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6636 d 13 h palkovsky /kernel/trunk/generic/ Changed ipc to use spinlocks instead of mutexes again.
Fixed loading inits to set nameservice as the first loaded process.
Lot of TODO in ipc done.		  
1037 6636 d 14 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1027 6637 d 1 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
973 6638 d 13 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6638 d 16 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6639 d 6 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6640 d 7 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
820 6672 d 3 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.		  
817 6672 d 11 h palkovsky /kernel/trunk/ Small cleanup.  
794 6674 d 10 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
756 6680 d 1 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.		  
754 6681 d 2 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.		  
727 6692 d 3 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
718 6696 d 4 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 6696 d 7 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
703 6698 d 12 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().		  
673 6708 d 4 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
654 6722 d 8 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.		  
629 6727 d 6 h decky /kernel/trunk/ init task loading (yet buggy)  
625 6727 d 9 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.		  
615 6729 d 14 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6730 d 8 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
578 6732 d 23 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....		  
534 6738 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6738 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6744 d 9 h jermar /kernel/trunk/ Clean up.  
518 6746 d 3 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 6747 d 2 h jermar /kernel/trunk/ Implement basic kernel console command recognition.
Commands without arguments are now recognized.		  
512 6749 d 12 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 6750 d 2 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 6750 d 5 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.		  
501 6750 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
459 6764 d 13 h decky /SPARTAN/trunk/ build system: CONFIG_TEST, CONFIG_USERSPACE  
458 6764 d 13 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6765 d 5 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
