4581 5668 d 1 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4153 5768 d 23 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5965 d 2 h decky /branches/network/ add new network branch (copy of current trunk)  
2141 6490 d 19 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.
 
2116 6541 d 4 h decky /trunk/kernel/generic/src/ddi/ explicit typecast  
2107 6542 d 21 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2071 6559 d 22 h jermar /trunk/ (c) versus (C)  
2015 6598 d 22 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.
 
2012 6601 d 20 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().
 
1888 6685 d 2 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1839 6725 d 3 h decky /trunk/kernel/generic/ finish security context isolation  
1787 6750 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6757 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 6775 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6777 d 7 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6778 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1589 6786 d 0 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 6786 d 1 h jermar /kernel/trunk/generic/src/ In task_kill(), remove the task from the tasks_btree before proceeding.
Thus, when the kernel finds the task in the tasks_btree and locks it before
releasing tasks_lock, it is guaranteed that the task will not be destroyed
until the lock is held. If the kernel needs to unlock the task, do some operation
and lock it again, it should increase its refcount before doing so. In that case,
when releasing the lock, it must decrement the refcount and if it reaches
zero, it must call task_destroy().
 
1494 6789 d 18 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1429 6794 d 9 h jermar /kernel/trunk/generic/ Make ddi_physmem_map() accept address space area flags instead of writable switch.
Thus even these types of address space areas can turn caching on, if it is desired.
