4490 6038 d 15 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3908 6145 d 16 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3790 6184 d 23 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3680 6216 d 21 h svoboda /trunk/kernel/generic/src/time/ Fix panic caused by NULL pointer dereference.  
3613 6232 d 0 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
2745 6500 d 23 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2275 6813 d 16 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2141 6837 d 11 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 6906 d 14 h jermar /trunk/ (c) versus (C)  
2015 6945 d 15 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 7096 d 17 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7103 d 18 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 7114 d 19 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 7117 d 23 h jermar /kernel/trunk/ Cleanup of comments.  
1731 7120 d 10 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 7123 d 23 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 7124 d 3 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 7124 d 21 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1457 7138 d 13 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1438 7140 d 13 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.
