3581 5724 d 22 h jermar /trunk/kernel/ Some cstyle.  
3577 5725 d 13 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3240 5828 d 10 h decky / move unfinished ObjC support to a separate branch  
3186 5866 d 2 h jermar /trunk/kernel/ Support for active mutexes. Active mutexes implement busy waiting, pretty much
in the same way as spinlocks, but can be passed to condition variables, which is
the motivation for this enhancement.
 
3104 5883 d 14 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5886 d 6 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2745 5983 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2572 6128 d 16 h jermar /trunk/kernel/ Remove duplicit implementation of strlen() in kernel, rename is_digit(),
is_white() and co. to their standard names (e.g. isdigit(), isspace()) and
remove duplicit implementation of isdigit(). Fix cstyle in kernel printf()
implementation.
 
2516 6154 d 0 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2510 6158 d 1 h jermar /trunk/kernel/ Experimental support for the cgsix framebuffer, which is found on old Ultra 1
worksations, and the SBUS bus and devices. Not tested.
 
2505 6191 d 12 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2465 6247 d 6 h jermar /trunk/ Merge arm32 into trunk.  
2441 6254 d 23 h decky /trunk/kernel/ fix ICC compilation  
2321 6276 d 6 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2222 6308 d 0 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2170 6315 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.
 
2141 6319 d 21 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2125 6364 d 1 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6372 d 8 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2102 6377 d 2 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2101 6377 d 2 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6377 d 2 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2089 6378 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2086 6380 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.
 
2071 6389 d 1 h jermar /trunk/ (c) versus (C)  
2054 6416 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 6428 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 6435 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 6445 d 7 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6445 d 8 h decky /trunk/ make framebuffer code more generic  
1991 6446 d 2 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6446 d 5 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6449 d 9 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1974 6460 d 2 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 6462 d 7 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1957 6471 d 9 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6471 d 10 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1944 6479 d 4 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1932 6481 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 6481 d 2 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.
