1944 6453 d 20 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6455 d 4 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6476 d 23 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.		  
1888 6488 d 21 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6490 d 1 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6491 d 1 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.		  
1837 6530 d 6 h jermar /trunk/ Support 24bpp framebuffers with 4 pixelbytes (each pixel aligned on 32-bits).

At least on sparc64, the OpenFirmware linebytes property specifies the number
of pixels between consecutive scan lines of the display. Fix scanilne calculation,
including possible alignment.

Add note to 8bpp pixel functions pointing out drawbacks of that mode.		  
1812 6541 d 0 h decky /trunk/kernel/ move macro and cleanup  
1787 6553 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6560 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6560 d 23 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6563 d 16 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.		  
1754 6575 d 3 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1749 6576 d 15 h decky /kernel/trunk/arch/mips32/src/ remove forgotten address translation  
1742 6576 d 18 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad booting address on MIPS when not compiled in debug mode.  
1741 6576 d 18 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Fix panic if continue after non-initialized kbd.  
1735 6577 d 3 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6577 d 13 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.		  
1705 6581 d 3 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 6581 d 6 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6582 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6585 d 3 h decky /kernel/trunk/ update mips32 boot loading API  
1678 6585 d 22 h jermar /kernel/trunk/ Load up to 8 userspace tasks on mips32.  
1642 6588 d 3 h vana /kernel/trunk/arch/mips32/src/ System info about machine  
1615 6588 d 22 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1595 6589 d 6 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.		  
1537 6592 d 14 h palkovsky /kernel/trunk/ Added tetris to  
1474 6594 d 16 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6595 d 16 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1434 6597 d 20 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1432 6598 d 2 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1411 6601 d 21 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.		  
1396 6604 d 18 h palkovsky /kernel/trunk/ Fixed mips to compile with fb (missing hw_map).
Fixed mips hw virt/phys addresses of fb.
Moved fb_init to post_mm, because it needs malloc().		  
1386 6604 d 23 h palkovsky /kernel/trunk/ Fixed mips bug fith TLS register not being properly saved on syscall context
switch.
Reverted SYS_IO, so that it could be used on machines without fb.		  
1354 6609 d 23 h palkovsky /kernel/trunk/ Support for mips kbd driver.  
1332 6611 d 17 h palkovsky /kernel/trunk/ Added support for more processes in mips.  
1293 6620 d 23 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6621 d 2 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.		  
1278 6623 d 20 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1260 6626 d 16 h palkovsky /kernel/trunk/ Small fixes.
