4581 5704 d 5 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4153 5805 d 4 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 6001 d 7 h decky /branches/network/ add new network branch (copy of current trunk)  
2170 6523 d 1 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 6596 d 3 h jermar /trunk/ (c) versus (C)  
1891 6717 d 1 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 6718 d 3 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 6745 d 10 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 6786 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6814 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 6820 d 23 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 6820 d 23 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1380 6838 d 4 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 6857 d 10 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
823 6939 d 0 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
788 6942 d 5 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 6948 d 7 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
741 6954 d 3 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 6954 d 9 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6959 d 1 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
