4490 5633 d 4 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4247 5691 d 8 h decky /trunk/kernel/generic/src/synch/ more readable spinning printout  
4220 5694 d 16 h decky /trunk/kernel/ update for string changes  
4137 5711 d 3 h svoboda /trunk/kernel/ Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.  
4132 5712 d 2 h svoboda /trunk/ Make kernel symbol information optional.  
3059 5998 d 9 h decky /trunk/kernel/generic/src/ proper printf formatting  
2211 6421 d 6 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6423 d 8 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.		  
2087 6491 d 6 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6501 d 3 h jermar /trunk/ (c) versus (C)  
1787 6691 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6698 d 7 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6712 d 11 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6719 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1667 6724 d 8 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.		  
1323 6749 d 14 h jermar /kernel/trunk/ Increase "timeout" for debugging spinlock so that false positive
deadlock reports are suppressed on real hardware.

Also add one HT configuration to hardware compatibility list.		  
1313 6750 d 11 h jermar /kernel/trunk/ Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().		  
1264 6762 d 11 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1224 6770 d 10 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.		  
1104 6802 d 6 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
