2227 6266 d 8 h decky /trunk/kernel/ start shutdown infrastructure  
2170 6274 d 16 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.
 
2110 6329 d 17 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2107 6330 d 17 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 6337 d 1 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6343 d 1 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6347 d 17 h jermar /trunk/ (c) versus (C)  
2065 6361 d 16 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6361 d 16 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2060 6366 d 3 h jermar /trunk/kernel/arch/ia64/src/ Fix typo.  
1945 6437 d 20 h jermar /trunk/kernel/arch/ia64/ ia64 work.
Move keyboard polling to a dedicated kernel thread.
Console initialization and console related sysinfo setup
can be now done in a single function.
 
1944 6437 d 20 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1942 6438 d 17 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1937 6439 d 4 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6460 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 6472 d 21 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6474 d 1 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6475 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.
 
1877 6478 d 4 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.
 
1851 6497 d 0 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 6500 d 3 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1787 6537 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6544 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6553 d 4 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
 
1760 6555 d 22 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 6561 d 3 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6561 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.
 
1708 6563 d 3 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6565 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 6565 d 6 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6565 d 6 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6566 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1675 6570 d 1 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6572 d 21 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1611 6572 d 22 h jermar /kernel/trunk/arch/ia64/src/ ia64 memcpy that is unaligned pointer resistent.  
1601 6573 d 5 h jermar /kernel/trunk/ Support loading up to 8 userspace images on ia64.  
1595 6573 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.
 
1570 6574 d 21 h vana /kernel/trunk/arch/ia64/src/ski/ Ia64 keyboard extension  
1548 6575 d 23 h vana /kernel/trunk/arch/ia64/src/ From/to kernel console switching on ia64  
1541 6576 d 6 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.
