Hello,
We 've build a gem5 implementation of a VTA-like architecture that uses the VTA
API. We are trying to run a simple application from VTA TVM on our
implementation but always fails with this error: `"Check failed:
(allow_missing) is false: Device API ext_dev is not enabled."` It crashes in
here:
int dtype_code = kDLFloat;
int dtype_bits = 32;
int dtype_lanes = 1;
int device_type = kDLExtDev;
int device_id = 0;
tvm::runtime::Module mod =
(*tvm::runtime::Registry::Get("tvm.graph_executor.create"))(json_data,
mod_dylib, device_type, device_id);
Just some more information:
- We are using an ARM-based implementation so the TVM runtime and VTA runtime
were compiled separately.
- We are using the vta-hw/apps/deploy example as our baseline. We had to make
several updates because the one provided was not working mostly due to
deprecated calls to the runtimes.
- We simply replace the VTA fsim runtime with our implementation (the VTA
runtime is the same but we use our own VTA driver). However, the execution
never reaches the point to call our VTA driver anw.
Any help would be appreciated. If you need any more information please let me
know.
Thanks,
andreas
