2454 6197 d 1 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2232 6254 d 2 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6254 d 16 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6254 d 16 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 6256 d 2 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6263 d 0 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 6311 d 2 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6319 d 1 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 6325 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6331 d 8 h decky /trunk/kernel/ typedef elimination  
2082 6331 d 9 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6332 d 3 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6336 d 1 h jermar /trunk/ (c) versus (C)  
2057 6363 d 13 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2023 6373 d 2 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6383 d 0 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 6384 d 6 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6392 d 9 h decky /trunk/ make framebuffer code more generic  
1980 6396 d 10 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1955 6418 d 13 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1949 6423 d 9 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.
 
1948 6423 d 12 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6426 d 4 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1936 6427 d 12 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6449 d 7 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 6457 d 0 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6457 d 10 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 6458 d 2 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 6461 d 5 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6462 d 9 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6463 d 9 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 6469 d 13 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1854 6477 d 11 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 6502 d 14 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 6513 d 8 h decky /trunk/kernel/ move macro and cleanup  
1802 6520 d 21 h decky /trunk/ cleanup and unify the build system  
1787 6526 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6533 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6533 d 7 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1769 6536 d 0 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.
