4296 5692 d 22 h trochtova /branches/dd/ dd branch synchronized with trunk (revision 4295)  
4156 5721 d 0 h trochtova /branches/dd/ changes in trunk (rev 4155) merged into dd branch  
4055 5732 d 2 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
3022 6015 d 4 h decky /branches/dd/ device drivers branch  
2211 6432 d 21 h decky /trunk/kernel/generic/src/synch/ reflect the renaming of printflock to printf_lock  
2183 6434 d 23 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 6502 d 21 h jermar /trunk/kernel/ Indentaion and formatting changes even Martin will like :-)  
2071 6512 d 18 h jermar /trunk/ (c) versus (C)  
1787 6702 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6709 d 22 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6724 d 3 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6731 d 0 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1667 6735 d 23 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 6761 d 5 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 6762 d 2 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 6774 d 3 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1224 6782 d 1 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.
 
1104 6813 d 22 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.
 
1100 6815 d 18 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
