2467 6355 d 3 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6360 d 6 h jermar /trunk/ Merge arm32 into trunk.  
2458 6362 d 5 h jermar /trunk/kernel/arch/mips32/ Fix mips32 build script.
Replace CFLAGS with GCC_CFLAGS.
 
2454 6363 d 0 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 6420 d 1 h decky /trunk/kernel/arch/mips32/src/ add support for halt/reboot in MSIM  
2227 6420 d 15 h decky /trunk/kernel/ start shutdown infrastructure  
2225 6420 d 15 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 6422 d 1 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2170 6428 d 23 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 6477 d 1 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6485 d 0 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 6491 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6497 d 8 h decky /trunk/kernel/ typedef elimination  
2082 6497 d 8 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6498 d 2 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6502 d 1 h jermar /trunk/ (c) versus (C)  
2057 6529 d 12 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.
 
2023 6539 d 2 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6548 d 23 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 6550 d 6 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6558 d 9 h decky /trunk/ make framebuffer code more generic  
1980 6562 d 9 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1955 6584 d 12 h decky /trunk/kernel/arch/mips32/ timer_fnc -> virtual_timer_fnc  
1949 6589 d 8 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.
 
1948 6589 d 11 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6592 d 4 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1936 6593 d 11 h decky /trunk/kernel/arch/mips32/ mips32: update for new IRQ subsystem  
1901 6615 d 6 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 6622 d 23 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6623 d 9 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 6624 d 1 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 6627 d 4 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6628 d 8 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1881 6629 d 8 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 6635 d 12 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1854 6643 d 10 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 6668 d 13 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 6679 d 7 h decky /trunk/kernel/ move macro and cleanup  
1802 6686 d 20 h decky /trunk/ cleanup and unify the build system  
1787 6692 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
