| H A D | tsb.h | diff 88826 Wed Jan 02 18:49:20 MST 2002 tmm 1. Implement an optimization for pmap_remove() and pmap_protect(): if a substantial fraction of the number of entries of tte's in the tsb would need to be looked up, traverse the tsb instead. This is crucial in some places, e.g. when swapping out a process, where a certain pmap_remove() call would take very long time to complete without this. 2. Implement pmap_qenter_flags(), which will become used later 3. Reactivate the instruction cache flush done when mapping as executable. This is required e.g. when executing files via NFS, but is known to cause problems on UltraSPARC-IIe CPU's. If you have such a CPU, you will need to comment this call out for now.
