2232 6265 d 9 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6265 d 23 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6274 d 7 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 6330 d 8 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 6336 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6347 d 8 h jermar /trunk/ (c) versus (C)  
1993 6403 d 16 h decky /trunk/ make framebuffer code more generic  
1955 6429 d 20 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1944 6437 d 12 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1936 6438 d 19 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6460 d 14 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 6472 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6473 d 16 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6474 d 16 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 6513 d 21 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 6524 d 15 h decky /trunk/kernel/ move macro and cleanup  
1787 6537 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6544 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6544 d 14 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6547 d 7 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 6558 d 18 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
 
1749 6560 d 6 h decky /kernel/trunk/arch/mips32/src/ remove forgotten address translation  
1742 6560 d 9 h palkovsky /kernel/trunk/arch/mips32/src/ Fix bad booting address on MIPS when not compiled in debug mode.  
1741 6560 d 9 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Fix panic if continue after non-initialized kbd.  
1735 6560 d 18 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6561 d 4 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 6564 d 18 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 6564 d 21 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6565 d 15 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1686 6568 d 18 h decky /kernel/trunk/ update mips32 boot loading API  
1678 6569 d 13 h jermar /kernel/trunk/ Load up to 8 userspace tasks on mips32.  
1642 6571 d 18 h vana /kernel/trunk/arch/mips32/src/ System info about machine  
1615 6572 d 13 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1595 6572 d 21 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 6576 d 5 h palkovsky /kernel/trunk/ Added tetris to  
1474 6578 d 7 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1458 6579 d 7 h palkovsky /kernel/trunk/ Added console support to gxemul.
Wider information in thread list.
 
1434 6581 d 11 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1432 6581 d 17 h jermar /kernel/trunk/arch/mips32/src/ Load four userspace tasks on mips32.  
1411 6585 d 12 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.
