3692 5669 d 21 h rimsky /trunk/ Fixed the bug when on SunBlade1500 we wrote to an address outside the framebuffer memory. A nasty hack to the 8-bit palette so that on sb1500 we do not have to turn black into white and white into black.  
3679 5673 d 18 h rimsky /trunk/ Added forgotten stuff related to framebuffers with offsets. Got rid of VISUAL_SB1500_PALETTE.  
3672 5674 d 23 h jermar /trunk/ Merge sparc branch to trunk.  
3661 5679 d 21 h vana /trunk/ IA64: repair similators support  
3657 5680 d 6 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3655 5680 d 22 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 5681 d 23 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3581 5698 d 20 h jermar /trunk/kernel/ Some cstyle.  
3577 5699 d 11 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3240 5802 d 8 h decky / move unfinished ObjC support to a separate branch  
3186 5840 d 0 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 5857 d 11 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5860 d 4 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2745 5957 d 7 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2572 6102 d 13 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 6127 d 22 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2510 6131 d 23 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 6165 d 9 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2467 6216 d 1 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6221 d 4 h jermar /trunk/ Merge arm32 into trunk.  
2441 6228 d 21 h decky /trunk/kernel/ fix ICC compilation  
2321 6250 d 4 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2222 6281 d 22 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 6289 d 20 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 6293 d 19 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 6337 d 23 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6346 d 5 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 6350 d 23 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2101 6350 d 23 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6351 d 0 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2093 6351 d 1 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6352 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2086 6354 d 2 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 6358 d 4 h decky /trunk/kernel/ typedef elimination  
2071 6362 d 22 h jermar /trunk/ (c) versus (C)  
2054 6390 d 21 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.
 
2015 6401 d 22 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 6409 d 21 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 6419 d 5 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6419 d 6 h decky /trunk/ make framebuffer code more generic
