2005 6389 d 17 h decky /trunk/ update rd  
2002 6389 d 19 h decky /trunk/kernel/generic/ rd work  
2000 6391 d 22 h decky /trunk/kernel/ move files to more proper locations  
1999 6391 d 22 h decky /trunk/ start RAM disk support  
1901 6454 d 18 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.		  
1855 6482 d 17 h jermar /trunk/kernel/ sparc64 work.

Fix bug introduced in revision 1852. When fixing CWP,
the input registers of the current window (i.e. output
registers of the window belonging to the interrupted
context) must be preserved. Preserve those registers
in memory. Sure there exist more efficient ways how to
copy the inputs.

Simplify before_thread_runs_arch(), resp. after_thread_ran_arch(),
and make them install, resp. uninstall, DTLB locked mapping for
eventual userspace window buffer.		  
1854 6482 d 22 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1787 6531 d 15 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot

1705 6558 d 21 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1702 6559 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1662 6565 d 0 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1659 6565 d 0 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1581 6568 d 1 h jermar /kernel/trunk/generic/src/ Detach kmp thread after joining it.
Extend assertion in thread_destroy() to not panic when threads are destroyed in their Unded state.		  
1576 6568 d 13 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1341 6588 d 12 h cejka /kernel/trunk/generic/src/main/ Added capability to register IRQs to tasks.  
1297 6596 d 18 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.		  
1248 6606 d 16 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1196 6617 d 20 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1174 6621 d 22 h jermar /kernel/trunk/ Start capabilities support.  
1062 6648 d 10 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 6648 d 20 h decky /kernel/trunk/generic/src/main/ more verbose warning  
1040 6648 d 21 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 6648 d 21 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1027 6649 d 8 h palkovsky /kernel/trunk/ Implemented callback IPC call (connect_to_me).  
973 6650 d 21 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
965 6650 d 23 h palkovsky /kernel/trunk/ Added skeleton name service.
Cleanup for IPC to use mutexes instead of spinlocks.		  
955 6651 d 13 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6652 d 14 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
820 6684 d 10 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 6684 d 19 h palkovsky /kernel/trunk/ Small cleanup.  
794 6686 d 17 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
756 6692 d 9 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 6693 d 9 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 6704 d 11 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
718 6708 d 12 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 6708 d 14 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time		  
703 6710 d 20 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 6720 d 11 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.		  
654 6734 d 15 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.
