4537 5671 d 21 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4536)  
4055 5770 d 18 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6053 d 20 h decky /branches/dd/ device drivers branch  
2745 6145 d 19 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2275 6458 d 12 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2141 6482 d 7 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 10 h jermar /trunk/ (c) versus (C)  
2015 6590 d 10 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.		  
1787 6741 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6748 d 13 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6759 d 15 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...		  
1757 6762 d 18 h jermar /kernel/trunk/ Cleanup of comments.  
1731 6765 d 6 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.		  
1705 6768 d 19 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.		  
1704 6768 d 23 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6769 d 16 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1457 6783 d 9 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1438 6785 d 8 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1434 6785 d 12 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1433 6785 d 16 h jermar /kernel/trunk/generic/src/time/ Fix critical bug in timeout processing introduced several hours ago.
