2227 6377 d 9 h decky /trunk/kernel/ start shutdown infrastructure  
2216 6378 d 19 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2170 6385 d 17 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.		  
2125 6433 d 19 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2110 6440 d 18 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2107 6441 d 18 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 6448 d 2 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6454 d 2 h decky /trunk/kernel/ typedef elimination  
2082 6454 d 2 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6454 d 20 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6458 d 19 h jermar /trunk/ (c) versus (C)  
2065 6472 d 17 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2064 6472 d 18 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2060 6477 d 4 h jermar /trunk/kernel/arch/ia64/src/ Fix typo.  
2057 6486 d 6 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2023 6495 d 20 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6505 d 17 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
2003 6507 d 0 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1945 6548 d 21 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 6548 d 22 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1942 6549 d 18 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1937 6550 d 5 h decky /trunk/kernel/arch/ remove orphaned functions  
1901 6572 d 0 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.		  
1891 6579 d 17 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6580 d 4 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1889 6580 d 19 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1888 6583 d 22 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6585 d 2 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6586 d 2 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 6589 d 6 h jermar /trunk/kernel/ Coding style fixes.
Remove unneeded sparc64 dummy functions.		  
1854 6600 d 4 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1851 6608 d 2 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 6611 d 5 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1802 6643 d 14 h decky /trunk/ cleanup and unify the build system  
1787 6648 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6655 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6664 d 5 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1760 6666 d 23 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 6672 d 4 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6672 d 15 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.
