Changeset ec443d5 in mainline for kernel/arch/sparc64/src/trap/exception.c

Timestamp:

2014-10-20T20:38:13Z (10 years ago)

Author:

Branches:

lfn, master, serial, ticket/834-toolchain-update, topic/msim-upgrade, topic/simplify-dev-export

Message:

Let most of the sparc64 traps go through exc_dispatch().

• All interrupts (level and vector_trap) now use exc_dispatch().
• Fast MMU traps still don't use it.
