2086 6340 d 4 h jermar /trunk/kernel/genarch/src/fb/ Don't write to frame buffer memory, which is past the resolution.
This fixes Ticket #17

Coding style a formatting changes in the frame buffer code.
 
2085 6344 d 6 h decky /trunk/kernel/ typedef elimination  
2071 6349 d 1 h jermar /trunk/ (c) versus (C)  
2054 6376 d 23 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.
 
2015 6388 d 1 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
2007 6395 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.
 
1994 6405 d 7 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6405 d 9 h decky /trunk/ make framebuffer code more generic  
1991 6406 d 2 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6406 d 5 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6409 d 9 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1974 6420 d 3 h jermar /trunk/kernel/genarch/src/ofw/ Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows.
 
1972 6422 d 7 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1957 6431 d 9 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6431 d 10 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1944 6439 d 4 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1932 6441 d 1 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.
 
1931 6441 d 2 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1925 6442 d 0 h jermar /trunk/kernel/genarch/src/kbd/ Support for grabbing and releasing z8530 keyboard for sparc64.
We might later add some locking.
 
1923 6442 d 0 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
