This is because if KDB_ENTER is implemented using a mechanism that can be masked by interrupt-level code, the KDB_ENTER would be ignored during interrupt processing. > > Is that describing a kernel developer's view of using KDB_ENTER, or > is this describing how someone should implement it for other > architectures?

Correct, it is aimed at people porting KDB to other architectures. scott > > Thanks, > --Steve > > Software Technologies Group, Inc. > http://www.stg.com >
