4581 5443 d 13 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4153 5544 d 12 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5740 d 15 h decky /branches/network/ add new network branch (copy of current trunk)  
2170 6262 d 9 h jermar /trunk/kernel/ Simplify synchronization in as_switch().
The function was oversynchronized, which
was causing deadlocks on the address
space mutex.

Now, address spaces can only be switched
when the asidlock is held. This also protects
stealing of ASIDs. No other synchronization
is necessary.		  
2071 6335 d 11 h jermar /trunk/ (c) versus (C)  
1891 6456 d 9 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 6457 d 11 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support		  
1851 6484 d 18 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1787 6525 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6553 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 6560 d 7 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 6560 d 7 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1380 6577 d 12 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 6596 d 18 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
823 6678 d 8 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
788 6681 d 13 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 6687 d 15 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
741 6693 d 11 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6693 d 17 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6698 d 9 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
