Hi guys,
I've always used the classic memory model when running timing simulations using
Arm, but I'd like to run some experiments using Ruby.
I've seen some people using it and asking questions about it, but my current
version of gem5 shows this warning when enabling it:
"warn: You are trying

Hi All:
When I simulate with the fastforward and maxinsts parameters in SE mod, I
only see sim_insts=my fastforward instructions in stats.txt after the maximum
number of instructions exits. The value of committedInsts is not always 0 in
switch_cpu.committedInsts, but if fastforward is removed
I am simulating a 4x4 Mesh_XY (16 nodes) with neighbor traffic pattern and
following parameters:
--cacheline_size=512 --sim-cycles=100 --sys-clock=1GHz --injectionrate=1.0
--ruby-clock=1GHz --inj-vnet=2 --routing-algorithm=1 --link-width-bits=256
--link-latency=1 --router-latency=1 --vcs-p
Hello,
I wanted to get the Avg TBE Size as a statistic for each of L1, L2, Dir and DMA
for all cores.
Please help me with some pointers as to where I should add code for TBE related
statistics,
I tried to get hints by looking at the L1Cache_Controller.cc file generated by
build.

Hi Arun,
Two quick ideas...
1. The address 0x56318e53ed40 looks suspect. That's not on the stack, in
the OS, on the heap... I think it's probably a bad address. Most likely
some other instruction before this one is causing a bad address to be
emitted.
2. CLWB/CLFLUSH/CLFLUSHOPT may or may not be
I am trying to run the example ruby_mem_test config and I am hitting the

Hi All:
I would like to use KVMCPU in SE mode on aarch64 so that I can use
-fast-forward more quickly to fastforward non-interested instrutions, but I
have seen that "fatal("KvmCPU can only be used in SE mode with x86")" in se.py,
so any plans to support it on aarch64?

Hi guys,
My gem5 version is the newest v21.0.
I build gem5 with command “scons build/X86_MSI/gem5.debug --default=X86
PROTOCOL=MESI_Three_Level SLICC_HTML=True”
And I write a simple multi-thread program.
#define THREAD 16
uint64_t sharei[8*THREAD]; //1 cachelines each thread
void work(void* arg
The program from
“https://www.gem5.org/documentation/learning_gem5/part3/running/“ saying that
“(note: as of this writing there is a bug in gem5 preventing this code from
executing).”
Is this bug exists in every multi-thread program running in gem5 with Ruby?
Does anyone know what the bug is?
