[gem5-users] Adding Non-Transactional Instruction

2022-03-07 Thread Beakal Lemeneh via gem5-users
Hello folks, I just finished building HTM support for RISCV in gem5, and I'm trying to experiment with the idea of having a non-transactional load and store in a given block of code that is in a transactional state. For example, if x = 1 is designated as a non-transactional instruction in a

Hello Kazi, Take a look at configs/example/gem5_library/arm-hello.py. It is a good example of SE mode for ARM ISA. If you are interested in instantiating a memory module look at lines 47, and 62 from the same file. P.S. I'm checking out the stable branch on the gem5 repo (Hash:

Kyle can you please take a look at this? Seems fwd_conv is broken with Vega from my reading of the output (which I was not aware of). But since we aren't testing Vega yet, it's perhaps not surprising something broke. David, in the meantime (if possible for your work) I would encourage you to

[gem5-users] Errors when writing to memory from accelerator

2022-03-07 Thread João Vieira via gem5-users
Hi! I am currently using gem5 to develop and evaluate HPC Co-processors in ARM-based systems. Most of such accelerators require direct access to the memory, and have to be able to translate memory addresses from the virtual address space to the physical address space. For doing so, I have
