3655 5649 d 16 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.
 
3646 5650 d 17 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3581 5667 d 13 h jermar /trunk/kernel/ Some cstyle.  
3577 5668 d 4 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3240 5771 d 1 h decky / move unfinished ObjC support to a separate branch  
3186 5808 d 17 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 5826 d 5 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5828 d 21 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2745 5926 d 0 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2572 6071 d 7 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 6096 d 15 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2510 6100 d 16 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 6134 d 3 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2467 6184 d 18 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6189 d 21 h jermar /trunk/ Merge arm32 into trunk.  
2441 6197 d 14 h decky /trunk/kernel/ fix ICC compilation  
2321 6218 d 21 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2222 6250 d 15 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 6258 d 14 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 6262 d 12 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.
