Hi, I’m trying to run int8 convolution on odroid xu4, and its architecture is armv7a.
I’ve only modified the TARGET_NAME of “topi/recipe/conv/test_conv_int8_arm.py” as below
TARGET_NAME = 'llvm -device=arm_cpu -target=armv7l-linux-gnueabihf -mattr=+v7,+dotprod'
And message are:
INFO:test_conv_int8_intel:Workload, Kernel_size, FP32_time, INT8_time, Speedup
WARNING:autotvm:Cannot find config for target=llvm -device=arm_cpu -target=armv7l-linux-gnueabihf -mattr=neon, workload=('conv2d_NCHWc', (1, 4, 56, 56, 16, 'float32'), (4, 4, 3, 3, 16, 16, 'float32'), 1, 1, (1, 1), 'NCHWc', 'NCHWc', 'float32'). A fallback configuration is used, which may bring great performance regression.

A fallback configuration is used, which may bring great performance regression.
LLVM ERROR: Cannot select: intrinsic %llvm.aarch64.neon.udot
It seems like tvm automatically chooses the target platform as aarch64…
And my questions are
- What is the proper configuration for armv7a?
- Does tvm supports int8 convolution for armv7a?
Thank you.
