2227 6317 d 3 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6325 d 10 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2107 6381 d 11 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2089 6387 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6398 d 12 h jermar /trunk/ (c) versus (C)  
1993 6454 d 20 h decky /trunk/ make framebuffer code more generic  
1955 6481 d 0 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1944 6488 d 15 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1936 6489 d 23 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6511 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.		  
1888 6523 d 16 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6524 d 20 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6525 d 20 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 6565 d 0 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 6575 d 18 h decky /trunk/kernel/ move macro and cleanup  
1787 6588 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6595 d 15 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6595 d 18 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6598 d 11 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 6609 d 22 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.		  
1749 6611 d 10 h decky /kernel/trunk/arch/mips32/src/ remove forgotten address translation  
1742 6611 d 12 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad booting address on MIPS when not compiled in debug mode.  
1741 6611 d 13 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Fix panic if continue after non-initialized kbd.  
1735 6611 d 22 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6612 d 8 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 6615 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.		  
1704 6616 d 1 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6616 d 18 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6619 d 22 h decky /kernel/trunk/ update mips32 boot loading API  
1678 6620 d 17 h jermar /kernel/trunk/ Load up to 8 userspace tasks on mips32.  
1642 6622 d 22 h vana /kernel/trunk/arch/mips32/src/ System info about machine  
1615 6623 d 16 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1595 6624 d 1 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 6627 d 8 h palkovsky /kernel/trunk/ Added tetris to  
1474 6629 d 10 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6630 d 10 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.		  
1434 6632 d 14 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1432 6632 d 21 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1411 6636 d 16 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 6639 d 13 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().
