2170 6309 d 21 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 0 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6372 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6378 d 6 h decky /trunk/kernel/ typedef elimination  
2079 6379 d 1 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6382 d 23 h jermar /trunk/ (c) versus (C)  
2057 6410 d 10 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2033 6418 d 6 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2023 6420 d 0 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6429 d 22 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 4 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6439 d 7 h decky /trunk/ make framebuffer code more generic  
1949 6470 d 7 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6470 d 9 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6473 d 2 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1934 6474 d 11 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6474 d 23 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.		  
1928 6475 d 5 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6475 d 10 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1901 6496 d 5 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 6503 d 22 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6504 d 8 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 0 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 3 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6509 d 7 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6524 d 9 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 11 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.		  
1802 6567 d 19 h decky /trunk/ cleanup and unify the build system  
1790 6571 d 2 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1787 6573 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6580 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1762 6589 d 20 h decky /kernel/trunk/arch/ppc32/src/cpu/ ppc32 identify known CPUs  
1758 6594 d 2 h decky /kernel/trunk/arch/ppc32/src/mm/ remove ASIDs from Page Hash Table  
1756 6594 d 8 h decky /kernel/trunk/arch/ppc32/ don't use hardcoded PIC address  
1743 6595 d 23 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6596 d 8 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1734 6596 d 18 h decky /kernel/trunk/arch/ppc32/ ppc32: kernel console grab & release  
1733 6596 d 19 h decky /kernel/trunk/arch/ppc32/src/mm/ fix segment register values, ppc32 works again (both w/ and w/o BAT)  
1731 6596 d 19 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.		  
1730 6596 d 19 h decky /kernel/trunk/arch/ppc32/ ppc32: BAT-less memory mapping (broken yet)
VSID support (broken yet)
boot API change
cleanup
