4692 5606 d 11 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
4377 5706 d 10 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
3684 5861 d 11 h svoboda /branches/tracing/ Merge latest trunk changes to tracing.  
3610 5876 d 19 h svoboda /branches/tracing/kernel/generic/src/time/ Correct condition for running udebug_before_thread_runs().  
3431 5943 d 9 h svoboda /branches/tracing/kernel/ Add configuration option CONFIG_UDEBUG to compile udebug in the kernel or not.  
3015 6054 d 19 h svoboda /branches/tracing/kernel/generic/ Call udebug_stoppable_begin() after scheduling, rather than before - avoid restricted contex.  
2925 6067 d 21 h svoboda /branches/tracing/ Merged latest trunk changes to tracing branch  
2869 6080 d 9 h svoboda /branches/tracing/kernel/generic/src/time/ Make preempted threads stoppable, so CPU-bound threads can be stopped  
2787 6116 d 14 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2745 6145 d 18 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2275 6458 d 11 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2183 6473 d 14 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 6482 d 6 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 6540 d 16 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6551 d 9 h jermar /trunk/ (c) versus (C)  
2015 6590 d 10 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 6741 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6748 d 13 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6759 d 14 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 6762 d 17 h jermar /kernel/trunk/ Cleanup of comments.
