Hi all,
I implemented an accelerator as a PIO device in the latest version of gem5 and
I am having issues with accessing the main memory for write operations. Reading
from main memory works correctly.
I used as an example an old entry "gem5-accel" that implements a Daxpy
accelerator (as far as

Answering your questions:
1. No, I build my own config file using the configs/example/apu_se.py as a
baseline
2. I have several simple memory objects on the accelerator that connect
directly on the membus that then connects to the memory controller. But I have
no iobridge between those
Hi all,
I implemented a device using the BasicPioDevice class but I can't seem to get
the read() & write() calls to work.
I assigned a pioAddr=0x2 and a pioSize=4096 and I try to write to the
device directly using these two methods:
Method 1:

uint32_t inp_params2 = 14;

Hi,
Thank you for the replies!
I mapped the physical address of the device to a virtual address and marked it
as uncacheable and did the trick for X86. So now using memcpy() I read/write
from and to the device using it's mapped virtual address.
However, for ARM it only works for read. Even if
