From b8790963359795b90a2ba6262d6df8496070f151 Mon Sep 17 00:00:00 2001 From: "Frank Ch. Eigler" Date: Wed, 10 Jun 1998 17:07:10 +0000 Subject: [PATCH] * Support for sky hardware interrupts. The sky-dma cannot trigger interrupts properly yet (jlemke TODO). Wed Jun 10 13:22:32 1998 Frank Ch. Eigler * interp.c (decode_coproc): For TX39, add stub COP0 register #7, to allay warnings. (interrupt_event): Made non-static. start-sanitize-tx3904 * dv-tx3904tmr.c (deliver_tx3904tmr_tick): Correct accidental interchange of configuration values for external vs. internal clock dividers. end-sanitize-tx3904 start-sanitize-sky * sky-device.c (sky_signal_interrupt): New function to generate interrupt event. * sky-device.h: Declare it. * sky-dma.c (check_int1): Call it. * sky-pke.c (pke_begin_interrupt_stall): Call it. end-sanitize-sky --- sim/mips/ChangeLog | 20 ++++++++++++++++++++ sim/mips/interp.c | 8 +++++++- sim/mips/sky-pke.c | 3 +-- 3 files changed, 28 insertions(+), 3 deletions(-) diff --git a/sim/mips/ChangeLog b/sim/mips/ChangeLog index 1be0821d747..9115a911a43 100644 --- a/sim/mips/ChangeLog +++ b/sim/mips/ChangeLog @@ -1,3 +1,23 @@ +Wed Jun 10 13:22:32 1998 Frank Ch.
