2222 6392 d 2 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust		  
2218 6393 d 0 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)		  
2216 6393 d 3 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2170 6400 d 1 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 6448 d 3 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2089 6462 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2083 6468 d 10 h decky /trunk/kernel/ typedef elimination  
2079 6469 d 4 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures  
2071 6473 d 3 h jermar /trunk/ (c) versus (C)  
2057 6500 d 14 h jermar /trunk/kernel/arch/ Fix all remaining mistmatches in width of byte swapping functions for ia64,
ppc32, ppc64, amd64, mips32 and ia32.		  
2033 6508 d 9 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2023 6510 d 4 h decky /trunk/kernel/arch/ add dummy cycle.h  
2007 6520 d 1 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 6521 d 8 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1993 6529 d 11 h decky /trunk/ make framebuffer code more generic  
1949 6560 d 10 h jermar /trunk/kernel/arch/ Remove notes about automatically generated context_offset.h
and replace it with a proper copyright notice.		  
1948 6560 d 13 h jermar /trunk/kernel/ Remove broken, outdated and unused gencontext.c utilities.  
1944 6563 d 6 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1934 6564 d 15 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1932 6565 d 3 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 6565 d 8 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1926 6565 d 13 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1901 6586 d 8 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 6594 d 1 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6594 d 12 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 6595 d 3 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 6598 d 6 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6599 d 10 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6614 d 12 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 6639 d 15 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 6657 d 22 h decky /trunk/ cleanup and unify the build system  
1790 6661 d 6 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 6663 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6670 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1762 6679 d 23 h decky /kernel/trunk/arch/ppc32/src/cpu/ ppc32 identify known CPUs  
1758 6684 d 6 h decky /kernel/trunk/arch/ppc32/src/mm/ remove ASIDs from Page Hash Table  
1756 6684 d 11 h decky /kernel/trunk/arch/ppc32/ don't use hardcoded PIC address  
1743 6686 d 2 h decky /kernel/trunk/arch/ppc32/src/mm/ fix compiler warning  
1736 6686 d 11 h decky /kernel/trunk/arch/ppc32/ verbose segment and BAT registers printout  
1734 6686 d 21 h decky /kernel/trunk/arch/ppc32/ ppc32: kernel console grab & release
