From 12d903a650a91798eae2389e70f7d4471d130919 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Sun, 20 Nov 2005 16:57:53 -0500 Subject: io_bus is split out into pio_bus and dma_bus so that any device can specify either independently. python/m5/objects/Device.py: io_bus is split out into pio_bus and dma_bus so that any device can specify either independently. dma_bus defaults to point to whatever pio_bus uses. --HG-- extra : convert_revision : d35d5374d0bf592f6b5df465c05203577b8b8763 --- python/m5/objects/Device.py | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'python/m5/objects/Device.py') diff --git a/python/m5/objects/Device.py b/python/m5/objects/Device.py index 7f6ccd3e7..d7ca014a9 100644 --- a/python/m5/objects/Device.py +++ b/python/m5/objects/Device.py @@ -16,12 +16,13 @@ class FooPioDevice(FunctionalMemory): abstract = True addr = Param.Addr("Device Address") mmu = Param.MemoryController(Parent.any, "Memory Controller") - io_bus = Param.Bus(NULL, "The IO Bus to attach to") + pio_bus = Param.Bus(NULL, "Bus to attach to for PIO") pio_latency = Param.Tick(1, "Programmed IO latency in bus cycles") class FooDmaDevice(FooPioDevice): type = 'DmaDevice' abstract = True + dma_bus = Param.Bus(Self.pio_bus, "Bus to attach to for DMA") class PioDevice(FooPioDevice): type = 'PioDevice' @@ -31,4 +32,4 @@ class PioDevice(FooPioDevice): class DmaDevice(PioDevice): type = 'DmaDevice' abstract = True - + dma_bus = Param.Bus(Self.pio_bus, "Bus to attach to for DMA") -- cgit v1.2.3
