lfn serial ticket/834-toolchain-update topic/msim-upgrade topic/simplify-dev-export
Last change on this file since c0b7f00 was 973be64e, checked in by Ondrej Palkovsky <ondrap@…>, 20 years ago

Added generic exc_register/exc_dispatch functions,
copied from ia32 architecture. Currently only mips32 uses them.

The chardev_t can now be both input & output device (was
needed for serial driver).

Broken other architectures - ia64, sparc, powerpc will not compile.

Mips32 supports input on all msim, gxemul, indy(tested emulation
in gxemul, loses characters), simics. Simics serial line
is done using polling, I was unable to make it produce
an interrupt when the key was pressed.
