Improved Address-Space Switching on Pentium Processors by Transparently Multiplexing User Address Spaces

Jochen Liedtke

GMD Technical Report No. 933, November 1995





Abstract:






Address-space switch requires a TLB flush on many processors. With
increasing TLB size, the secondary costs of address-space switching due to
TLB refill can thus increase substantially. For the Pentium processor, we
describe an optimization to avoid TLB flush in many cases. The method
is transparent to the user and thus requires no extension of 
the microkernel interface.
