4490 5638 d 1 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3908 5745 d 1 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3790 5784 d 8 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 5816 d 7 h svoboda /trunk/kernel/generic/src/time/ Fix panic caused by NULL pointer dereference.  
3613 5831 d 9 h svoboda /trunk/kernel/generic/ Merge feature from tracing: correct stopping of CPU-intensive tasks in udebug.  
2745 6100 d 8 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2275 6413 d 2 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2141 6436 d 21 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 6506 d 0 h jermar /trunk/ (c) versus (C)  
2015 6545 d 0 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 6696 d 2 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6703 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6714 d 4 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 6717 d 8 h jermar /kernel/trunk/ Cleanup of comments.  
1731 6719 d 20 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 6723 d 9 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 6723 d 12 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6724 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1457 6737 d 22 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1438 6739 d 22 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.
