I have a few questions about user applications. When a new user process is started will its user space be cleared by the kernel or is there a potential leak from an older user process ? What about the registers values, are they cleared for each new user application or will it simply contain the current value it got when the user application is started ? How can you flush the data and instruction cashes from a user application ? /Carsten -- _ _ ____ ___ Carsten Langgaard Mailto:carstenl@mips.com |\ /|||___)(___ MIPS Denmark Direct: +45 4486 5527 | \/ ||| ____) Lautrupvang 4B Switch: +45 4486 5555 TECHNOLOGIES 2750 Ballerup Fax...: +45 4486 5556 Denmark http://www.mips.com
