3680 5641 d 1 h svoboda /trunk/kernel/generic/src/time/ Fix panic caused by NULL pointer dereference.  
3613 5656 d 3 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
2745 5925 d 3 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2275 6237 d 20 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2141 6261 d 15 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 6330 d 18 h jermar /trunk/ (c) versus (C)  
2015 6369 d 18 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 6520 d 20 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6527 d 21 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6538 d 22 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 6542 d 2 h jermar /kernel/trunk/ Cleanup of comments.  
1731 6544 d 14 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 6548 d 3 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 6548 d 6 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6549 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1457 6562 d 17 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1438 6564 d 16 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1434 6564 d 20 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1433 6564 d 23 h jermar /kernel/trunk/generic/src/time/ Fix critical bug in timeout processing introduced several hours ago.  
1431 6565 d 3 h jermar /kernel/trunk/generic/ Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
