3610 5650 d 11 h svoboda /branches/tracing/kernel/generic/src/time/ Correct condition for running udebug_before_thread_runs().  
3431 5717 d 1 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3015 5828 d 11 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
2925 5841 d 13 h svoboda /branches/tracing/ Merged latest trunk changes to tracing branch  
2869 5854 d 1 h svoboda /branches/tracing/kernel/generic/src/time/ Make preempted threads stoppable, so CPU-bound threads can be stopped  
2787 5890 d 6 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 5919 d 10 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2275 6232 d 3 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2183 6247 d 6 h jermar /trunk/kernel/generic/ Continue to de-oversynchronize the kernel.
- replace as->refcount with an atomic counter; accesses to this
reference counter are not to be done when the as->lock mutex is held;
this gets us rid of mutex_lock_active();

Remove the possibility of a deadlock between TLB shootdown and asidlock.
- get rid of mutex_lock_active() on as->lock
- when locking the asidlock spinlock, always do it conditionally and with
preemption disabled; in the unsuccessful case, enable interrupts and try again
- there should be no deadlock between TLB shootdown and the as->lock mutexes
- PLEASE REVIEW !!!

Add DEADLOCK_PROBE's to places where we have spinlock_trylock() loops.
 
2141 6255 d 22 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.
 
2089 6314 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6325 d 1 h jermar /trunk/ (c) versus (C)  
2015 6364 d 2 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 6515 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6522 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6533 d 6 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 6536 d 10 h jermar /kernel/trunk/ Cleanup of comments.  
1731 6538 d 21 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 6542 d 11 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 6542 d 14 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.
