Subject: [Qemu-devel] MIPS interrupt handling
Date: Wed, 03 May 2006 00:28:47 +0200 [thread overview]
Message-ID: <4457DD1F.7040307@bellard.org> (raw)
I just looked at the MIPS file target-mips/op_helper.c and I don't
understand why IRQs need to be handled in op_helper.c:do_mtc0() with reg
= 12. IMHO, the corresponding code should be deleted because the TB is
forced to terminate after mtc0 so that the IRQs can be handled in the
main loop in cpu-exec.c.
Moreover, clearing CPU_INTERRUPT_HARD in do_mtc0() is almost surely a bug !
Fabrice.
