The following occurs when attempting to run almost any algorithm on hashcat

[CLVK] clSetKernelArg: passing a null pointer to clSetKernelArg is only supported for local arguments
clSetKernelArg(): CL_INVALID_ARG_VALUE

This is kind of expected. At the moment, clvk does not support passing a null pointer to clSetKernelArg.

But if you execute with the following env variables, it should:

CLVK_SPIRV_ARCH=spir64
CLVK_PHYSICAL_ADDRESSING=1

At the point, this configuration will become the default one in clvk.

[zwang20]

using the env variables

CLVK_SPIRV_ARCH=spir64
CLVK_PHYSICAL_ADDRESSING=1

still results in

[CLVK] clSetKernelArg: passing a null pointer to clSetKernelArg is only supported for local arguments
clSetKernelArg(): CL_INVALID_ARG_VALUE

Sorry I misread the error message. I'll have a closer look then

[zwang20]

certain algorithms produce errors similar to the following

[CLVK] Loaded SPIR-V binary from "clvk-K8YQe9/compiled.spv", size = 31348 words
error: 3548: Expected input to have different bit width from Result Type: UConvert
  %2379 = OpUConvert %uint %2326

[CLVK] SPIR-V binary is invalid.
