Thx Micheal NALLINO, your workaround solved my issue.
I'm running: Linux Mint 21.1 Cinnamon Kernel: 5.15.0.16-generic NVIDIA GeForce GTX 550 Ti (GF116) and opencl is now recognized. I had the same issue on my Asus U36S laptop and is now solved too. Laptop: Linux Mint 21.1 Cinnamon Kernel: 5.15.0.16-generic NVIDIA GeForce GT 520M Thx -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.15 in Ubuntu. https://bugs.launchpad.net/bugs/1993539 Title: Nvidia GeForce GTX 560 M not recognized as an OpenCL platform with 5.15.0-50 kernel Status in linux-hwe-5.15 package in Ubuntu: New Bug description: Hi, Before to update to Linux Mint 21, based on Ubuntu 22.04 LTS, I have tried 5.15.0-50 kernel with HWE. This was intended as a test of my hardware compatibility with the hardware stack of Ubuntu 22.04, before a possible update. At a first glance, all seemed OK; nut I noticed that LibreOffice was unable to use OpenCL. A simple "clinfo" command confirmed this: $ clinfo Number of platforms 0 I went back from 5.15.0-50 kernel to 5.4.0-128 one. Now, "clinfo" output is: $ clinfo Number of platforms 1 Platform Name NVIDIA CUDA Platform Vendor NVIDIA Corporation Platform Version OpenCL 1.2 CUDA 9.1.84 Platform Profile FULL_PROFILE Platform Extensions cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_fp64 cl_khr_byte_addressable_store cl_khr_icd cl_khr_gl_sharing cl_nv_compiler_options cl_nv_device_attribute_query cl_nv_pragma_unroll cl_nv_copy_opts cl_nv_create_buffer Platform Extensions function suffix NV Platform Name NVIDIA CUDA Number of devices 1 Device Name GeForce GTX 560M Device Vendor NVIDIA Corporation Device Vendor ID 0x10de Device Version OpenCL 1.1 CUDA Driver Version 390.154 Device OpenCL C Version OpenCL C 1.1 Device Type GPU Device Topology (NV) PCI-E, 01:00.0 Device Profile FULL_PROFILE Device Available Yes Compiler Available Yes Max compute units 4 Max clock frequency 1550MHz Compute Capability (NV) 2.1 Max work item dimensions 3 Max work item sizes 1024x1024x64 Max work group size 1024 Preferred work group size multiple 32 Warp size (NV) 32 Preferred / native vector sizes char 1 / 1 short 1 / 1 int 1 / 1 long 1 / 1 half 0 / 0 (n/a) float 1 / 1 double 1 / 1 (cl_khr_fp64) Half-precision Floating-point support (n/a) Single-precision Floating-point support (core) Denormals Yes Infinity and NANs Yes Round to nearest Yes Round to zero Yes Round to infinity Yes IEEE754-2008 fused multiply-add Yes Support is emulated in software No Correctly-rounded divide and sqrt operations No Double-precision Floating-point support (cl_khr_fp64) Denormals Yes Infinity and NANs Yes Round to nearest Yes Round to zero Yes Round to infinity Yes IEEE754-2008 fused multiply-add Yes Support is emulated in software No Address bits 64, Little-Endian Global memory size 3150839808 (2.934GiB) Error Correction support No Max memory allocation 787709952 (751.2MiB) Unified memory for Host and Device No Integrated memory (NV) No Minimum alignment for any data type 128 bytes Alignment of base address 4096 bits (512 bytes) Global Memory cache type Read/Write Global Memory cache size 65536 (64KiB) Global Memory cache line size 128 bytes Image support Yes Max number of samplers per kernel 16 Max 2D image size 16384x16384 pixels Max 3D image size 2048x2048x2048 pixels Max number of read image args 128 Max number of write image args 8 Local memory type Local Local memory size 49152 (48KiB) Registers per block (NV) 32768 Max number of constant args 9 Max constant buffer size 65536 (64KiB) Max size of kernel argument 4352 (4.25KiB) Queue properties Out-of-order execution Yes Profiling Yes Profiling timer resolution 1000ns Execution capabilities Run OpenCL kernels Yes Run native kernels No Kernel execution timeout (NV) Yes Concurrent copy and kernel execution (NV) Yes Number of async copy engines 1 Device Extensions cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics cl_khr_fp64 cl_khr_byte_addressable_store cl_khr_icd cl_khr_gl_sharing cl_nv_compiler_options cl_nv_device_attribute_query cl_nv_pragma_unroll cl_nv_copy_opts cl_nv_create_buffer NULL platform behavior clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...)
