4377 5706 d 9 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3675 5863 d 7 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
2787 6116 d 12 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 6145 d 17 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2141 6482 d 5 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.
 
2071 6551 d 8 h jermar /trunk/ (c) versus (C)  
2048 6583 d 10 h jermar /trunk/ Formatting and indentation changes.  
2015 6590 d 8 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.
 
1982 6611 d 16 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
 
1918 6651 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Omitted comma.  
1917 6651 d 9 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.
 
1903 6663 d 9 h jermar /trunk/ SMP stuff for sparc64.
Almost complete except for IPIs.
The absence of IPI support deadlocks
the kernel when more CPUs are configured.
 
1888 6676 d 12 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1841 6712 d 16 h jermar /trunk/kernel/ Start reorganization of different keyboard drivers.
What seemed like a screwed i8042 chip appears to be
Zilog 8530.

The repository won't compile now. To be fixed in next commits.
 
1793 6738 d 17 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1787 6741 d 10 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6748 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1770 6749 d 13 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.  
1760 6759 d 13 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1702 6769 d 14 h cejka /kernel/trunk/ Kernel doxygen comments updated.
