3186 5979 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 5996 d 13 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5999 d 5 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2745 6096 d 8 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2572 6241 d 15 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 6266 d 23 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2510 6271 d 0 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 6304 d 11 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2467 6355 d 2 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6360 d 5 h jermar /trunk/ Merge arm32 into trunk.  
2441 6367 d 23 h decky /trunk/kernel/ fix ICC compilation  
2321 6389 d 5 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2222 6420 d 23 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 6428 d 22 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 6432 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 6477 d 0 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6485 d 7 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 6490 d 1 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2101 6490 d 1 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6490 d 2 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast
