4691 5970 d 3 h svoboda /branches/dynload/ Merge trunk changes up to r4686.  
4337 6082 d 2 h svoboda /branches/dynload/ Merge changes in trunk up to r3741 to dynload.  
2927 6431 d 12 h decky /branches/dynload/ added dynload branch  
2170 6841 d 23 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 6915 d 1 h jermar /trunk/ (c) versus (C)  
1891 7035 d 23 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1889 7037 d 1 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 7064 d 8 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 7105 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 7133 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 7139 d 21 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 7139 d 21 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1380 7157 d 2 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.		  
1266 7176 d 8 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.		  
823 7257 d 22 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
788 7261 d 4 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 7267 d 5 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
741 7273 d 1 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 7273 d 7 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 7277 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
