2232 6301 d 7 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6301 d 21 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6301 d 21 h decky /trunk/kernel/arch/mips32/ the bss and common sections have to be in .data output section to be properly generated in the binary image
(this might break IRIX, but it is already unmaintaned)
 
2216 6303 d 7 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6310 d 5 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 6358 d 7 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6366 d 6 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 6372 d 14 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6378 d 14 h decky /trunk/kernel/ typedef elimination  
2082 6378 d 14 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6379 d 8 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6383 d 7 h jermar /trunk/ (c) versus (C)  
2057 6410 d 18 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2023 6420 d 7 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6430 d 5 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 6431 d 11 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6439 d 14 h decky /trunk/ make framebuffer code more generic  
1980 6443 d 15 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1955 6465 d 18 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1949 6470 d 14 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.
 
1948 6470 d 17 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6473 d 10 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1936 6474 d 17 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6496 d 12 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 6504 d 5 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6504 d 15 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 6505 d 7 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 6508 d 10 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6509 d 14 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6510 d 14 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.
 
1871 6516 d 18 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1854 6524 d 16 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.
 
1837 6549 d 19 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 6560 d 13 h decky /trunk/kernel/ move macro and cleanup  
1802 6568 d 2 h decky /trunk/ cleanup and unify the build system  
1787 6573 d 9 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6580 d 10 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6580 d 12 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6583 d 5 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 6594 d 16 h jermar /kernel/trunk/ Indentation and some improved comments.
Remove forgotten comment from gxemul.sh.
