1881 6507 d 8 h jermar /trunk/ sparc64 work:
- find a CPU node and read its clock_frequency attribute
- implement asm_delay_loop()
- set TICK_COMPARE register according to processor frequency
- small improvements at random places

OpenFirmware work:
- two new functions for walking the device tree

Generic boot loader work:
- added basic string functions

Usual pile of indentation and formatting fixes.		  
1877 6510 d 12 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1851 6529 d 8 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1850 6532 d 11 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1787 6570 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6585 d 11 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6588 d 5 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1735 6593 d 10 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6593 d 21 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.		  
1708 6595 d 10 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6597 d 10 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6597 d 13 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6597 d 13 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6598 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1675 6602 d 8 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6605 d 4 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1611 6605 d 6 h jermar /kernel/trunk/arch/ia64/src/ ia64 memcpy that is unaligned pointer resistent.  
1601 6605 d 12 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1595 6605 d 14 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.		  
1570 6607 d 4 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1548 6608 d 6 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1541 6608 d 13 h jermar /kernel/trunk/ Modify ia64 to load 6 userspace tasks.
Tetris however makes the kernel fault on unaligned memory access in copy_from_uspace.		  
1507 6609 d 7 h vana /kernel/trunk/ IA64 uspace keyboard kernel part  
1495 6609 d 20 h jermar /kernel/trunk/ Remove three infinite loops introduced yesterday :-)

Make ia64 ready to load 5 ELF images.		  
1482 6610 d 7 h vana /kernel/trunk/arch/ia64/src/drivers/ Misseed clock ticks counting  
1474 6610 d 23 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1411 6618 d 4 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1295 6636 d 8 h jermar /kernel/trunk/arch/ia64/ Complete implementation of memcpy_from_uspace() and memcpy_to_uspace().
The memcpy() variants are based on the assembler output of the generic
_memcpy().		  
1290 6637 d 7 h vana /kernel/trunk/arch/ VESA detection failure fix.

(Some headers)		  
1288 6637 d 9 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1280 6640 d 1 h jermar /kernel/trunk/arch/ Get rid off obsolete ddi_int_control_arch() on ia64, sparc64 and ppc32.  
1265 6641 d 8 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1227 6649 d 5 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.		  
1223 6649 d 9 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1221 6649 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1210 6651 d 8 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1196 6656 d 8 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1191 6658 d 12 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.		  
1187 6659 d 4 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
