2015 7004 d 16 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 7007 d 14 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 7090 d 19 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1839 7130 d 20 h decky /trunk/kernel/generic/ finish security context isolation  
1787 7155 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 7162 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1708 7181 d 1 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 7183 d 1 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 7183 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1589 7191 d 18 h jermar /kernel/trunk/generic/src/ Improve comments regarding liveliness of threads and tasks.  
1588 7191 d 18 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 7195 d 12 h palkovsky /kernel/trunk/generic/ Removes unnecessary parameter for map_physmem syscall.  
1429 7200 d 2 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.
 
1425 7200 d 16 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 7200 d 19 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.
 
1409 7204 d 13 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.
 
1297 7220 d 21 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1288 7223 d 0 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1278 7225 d 18 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1248 7230 d 19 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.
