OS Linux Mint 20.1
GPU RX 570

I have installed the latest ROCm drivers for my GPU and when I do the hashcat -I command this is what it displays...





Code:
root@rob-System-Product-Name:/home/rob# hashcat -I hashcat (v5.1.0) starting... clGetDeviceIDs(): CL_DEVICE_NOT_FOUND OpenCL Info: Platform ID #1   Vendor  : The pocl project   Name    : Portable Computing Language   Version : OpenCL 1.2 pocl 1.4, None+Asserts, LLVM 9.0.1, RELOC, SLEEF, DISTRO, POCL_DEBUG   Device ID #1     Type          : CPU     Vendor ID      : 128     Vendor        : GenuineIntel     Name          : pthread-Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz     Version        : OpenCL 1.2 pocl HSTR: pthread-x86_64-pc-linux-gnu-sandybridge     Processor(s)  : 4     Clock          : 5900     Memory        : 4096/13933 MB allocatable     OpenCL Version : OpenCL C 1.2 pocl     Driver Version : 1.4 Platform ID #2   Vendor  : Intel(R) Corporation   Name    : Intel(R) OpenCL   Version : OpenCL 1.2 LINUX   Device ID #2     Type          : CPU     Vendor ID      : 8     Vendor        : Intel(R) Corporation     Name          : Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz     Version        : OpenCL 1.2 (Build 37)     Processor(s)  : 4     Clock          : 3300     Memory        : 3995/15981 MB allocatable     OpenCL Version : OpenCL C 1.2     Driver Version : 1.2.0.37 Platform ID #3   Vendor  : Advanced Micro Devices, Inc.   Name    : AMD Accelerated Parallel Processing   Version : OpenCL 2.0 AMD-APP (3212.0)


However, when I attempt to crack some simple md5 hashes. It doesn't use my GPU. the output is below

Code:

I have tried to uninstall POCL but everytime I do that it automatically uninstalls hashcat?

Help would be very much appreciated.

first: -> never use --force
second:
hashcat (v5.1.0) starting...

this is an older version, try downloading, compiling and using the gitversion (v6.1.1***)

third:
amd on linux seems littel bit tricky, see this thread

You need to remove POCL first then install the proper drivers.

I think I am having a similar issue. It seems to see my AMD Threadripper but not the GPU's. Both are slotted in PCIE 3 slots ( At least I am fairly certain they are). Any ideas?

Ubuntu 20.04 (fresh minimal install)
(2) RX 580's
Threadripper 1950X
amdgpu 21.2.6 (open source)
ROCm 5.4.1.50401-84~20.04
hashcat v6.2.6



Code:
hashcat (v5.1.0) starting... clGetDeviceIDs(): CL_DEVICE_NOT_FOUND OpenCL Info: Platform ID #1   Vendor  : The pocl project   Name    : Portable Computing Language   Version : OpenCL 1.2 pocl 1.4, None+Asserts, LLVM 9.0.1, RELOC, SLEEF, DISTRO, POCL_DEBUG   Device ID #1     Type          : CPU     Vendor ID      : 1     Vendor        : AuthenticAMD     Name          : pthread-AMD Ryzen Threadripper 1950X 16-Core Processor     Version        : OpenCL 1.2 pocl HSTR: pthread-x86_64-pc-linux-gnu-znver1     Processor(s)  : 16     Clock          : 3400     Memory        : 16384/62112 MB allocatable     OpenCL Version : OpenCL C 1.2 pocl     Driver Version : 1.4 Platform ID #2   Vendor  : Advanced Micro Devices, Inc.   Name    : AMD Accelerated Parallel Processing   Version : OpenCL 2.1 AMD-APP (3513.0)
