4691 6080 d 11 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4337 6192 d 10 h svoboda /branches/dynload/ Merge changes in trunk up to r3741 to dynload.  
2927 6541 d 20 h decky /branches/dynload/ added dynload branch  
2170 6952 d 7 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 7025 d 9 h jermar /trunk/ (c) versus (C)  
1891 7146 d 7 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 7147 d 9 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 7174 d 16 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 7215 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 7243 d 15 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 7250 d 5 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 7250 d 5 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1380 7267 d 10 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 7286 d 16 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
823 7368 d 6 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
788 7371 d 11 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 7377 d 13 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
741 7383 d 9 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 7383 d 15 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 7388 d 7 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
