I just add Ethernet object and add it to pci_device, and when I bootup with
fs.py, NoncoherentXBAR debug print will print

主题: How to enable dist-gem5 on GEM5 20.0.0.3 on ARM64
Hi All:
Any one use dist-gem5 to bootup successfully on GEM5 20.0.0.3 on ARM64?
In dist-gem5 website, the example only shows for arm32, and the
kernel/img/boot_emm/vexpress_emm is just matched for arm32.
I want to use the latest 4.14 kernel and
aarch64-ubuntu-trusty-headless.img from GEM5 website with KVM bootup, how to
enable it?

主题: Unable to find destination for [0x40000008:0x4000000c] on system.iobus
Hi All:
I just add a ethernet object in dist-bigLITTLE.py on VEXPRESS_GEM5_V1, but
AddRange debug print “fatal: Unable to find destination for
[0x40000008:0x4000000c] on system.iobus
So how to config the mem range in RealView.py or in any other code ?
”
The function of create Ethernet is :
def addEthernet(system, options):
# create NIC
dev = IGbE_e1000()
system.attach_pci(dev)
system.ethernet = dev
# create distributed ethernet link
system.etherlink = DistEtherLink(speed = options.ethernet_linkspeed,
delay = options.ethernet_linkdelay,
dist_rank = options.dist_rank,
dist_size = options.dist_size,
server_name = options.dist_server_name,
server_port = options.dist_server_port,
sync_start = options.dist_sync_start,
sync_repeat = options.dist_sync_repeat)
system.etherlink.int0 = Parent.system.ethernet.interface
if options.etherdump:
system.etherdump = EtherDump(file=options.etherdump)
system.etherlink.dump = system.etherdump
