3675 5671 d 3 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3597 5686 d 3 h svoboda /branches/tracing/ Merge latest trunk changes into tracing.  
3425 5751 d 15 h svoboda /branches/tracing/ Merge latest trunk changes into tracing (broken)  
3424 5752 d 3 h svoboda /branches/tracing/ Merge trunk changes up to r3180 into tracing  
2787 5924 d 8 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 5953 d 13 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2572 6098 d 20 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 6124 d 4 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2510 6128 d 5 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 6161 d 15 h jermar /trunk/kernel/genarch/src/softint/ Minor cleanup of softint.  
2467 6212 d 7 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6217 d 10 h jermar /trunk/ Merge arm32 into trunk.  
2441 6225 d 3 h decky /trunk/kernel/ fix ICC compilation  
2321 6246 d 10 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2222 6278 d 4 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 6286 d 2 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 6290 d 1 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 6334 d 5 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2106 6342 d 11 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 6347 d 5 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast  
2101 6347 d 5 h decky /trunk/kernel/ fix signed/unsigned comparison and integer overflow  
2100 6347 d 6 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast  
2093 6347 d 8 h decky /trunk/kernel/ spinlock extern declaration macro  
2089 6348 d 11 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2086 6350 d 8 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 6354 d 10 h decky /trunk/kernel/ typedef elimination  
2071 6359 d 4 h jermar /trunk/ (c) versus (C)  
2054 6387 d 3 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.
 
2015 6398 d 5 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 6406 d 3 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 6415 d 11 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6415 d 12 h decky /trunk/ make framebuffer code more generic  
1991 6416 d 5 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6416 d 9 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6419 d 12 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1974 6430 d 6 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 6432 d 11 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1957 6441 d 12 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6441 d 14 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1944 6449 d 7 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
