4692 5568 d 2 h svoboda /branches/tracing/ Merge trunk changes up to r4686.  
4377 5668 d 1 h svoboda /branches/tracing/ Merge latest trunk changes to tracing. (i.e. revs 3684:4374, huge). This time hopefully the real thing.  
2787 6078 d 5 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2170 6439 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 6513 d 0 h jermar /trunk/ (c) versus (C)  
1891 6633 d 23 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1889 6635 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 6662 d 7 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 6703 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1702 6731 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1637 6737 d 20 h jermar /kernel/trunk/genarch/src/mm/ Improve comment.  
1636 6737 d 20 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.
 
1380 6755 d 1 h jermar /kernel/trunk/ Turn address space lock, address space area lock and
page_ht_lock into mutexes.
 
1266 6774 d 7 h jermar /kernel/trunk/genarch/ Rename acpi/matd.c to madt.c (Multiple APIC Description Table).
Improve Doxygen comments in genarch/.
 
823 6855 d 21 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
788 6859 d 3 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
753 6865 d 4 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
 
741 6871 d 0 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 6871 d 6 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6875 d 23 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
