When I filtered the mesa source code with keyword "PIPE_COMPUTE_CAP_IMAGES_SUPPORTED", I found the following code information. ******************************************************************************** [root@localhost mesa-18.0.5]# grep "PIPE_COMPUTE_CAP_IMAGES_SUPPORTED" . -rn ./src/gallium/drivers/softpipe/sp_screen.c:551: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/drivers/freedreno/freedreno_screen.c:705: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/drivers/r600/r600_pipe_common.c:1120: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/drivers/nouveau/nv50/nv50_screen.c:444: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/drivers/nouveau/nvc0/nvc0_screen.c:518: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/drivers/radeonsi/si_get.c:864: case PIPE_COMPUTE_CAP_IMAGES_SUPPORTED: ./src/gallium/docs/source/screen.rst:560:* ``PIPE_COMPUTE_CAP_IMAGES_SUPPORTED``: Whether images are supported ./src/gallium/include/pipe/p_defines.h:920: PIPE_COMPUTE_CAP_IMAGES_SUPPORTED, ./src/gallium/state_trackers/clover/core/device.cpp:185: PIPE_COMPUTE_CAP_IMAGES_SUPPORTED)[0]; ******************************************************************************** I also found a similar bug submission as follows, but it is not clear whether the relevant patch provided in the article has been officially verified by mesa and is applicable to the version of mesa 18.0.5. https://bugs.freedesktop.org/show_bug.cgi?id=87738 |

When enumerating OpenCL platforms and devices with the clinfo command, I found that OpenCL devices (AMD Radeon HD 8470) do not support OpenCL images. I don't understand why this problem occurs. I don't even understand whether this is a fault in the graphics card itself or the graphics card driver, or ignore several options when compiling mesa. ********************************************************************************* [root@localhost /]# clinfo Number of platforms 1 Platform Name Clover Platform Vendor Mesa Platform Version OpenCL 1.1 Mesa 18.0.5 Platform Profile FULL_PROFILE Platform Extensions cl_khr_icd Platform Extensions function suffix MESA Platform Name Clover Number of devices 1 Device Name AMD CAICOS (DRM 2.49.0 / 3.10.84-21.fc21.loongson.18.mips64el, LLVM 8.0.0) Device Vendor AMD Device Vendor ID 0x1002 Device Version OpenCL 1.1 Mesa 18.0.5 Driver Version 18.0.5 Device OpenCL C Version OpenCL C 1.1 Device Type GPU Device Profile FULL_PROFILE Max compute units 2 Max clock frequency 775MHz Max work item dimensions 3 Max work item sizes 256x256x256 Max work group size 256 Preferred work group size multiple 64 Preferred / native vector sizes char 16 / 16 short 8 / 8 int 4 / 4 long 2 / 2 half 0 / 0 (n/a) float 4 / 4 double 0 / 0 (n/a) Half-precision Floating-point support (n/a) Single-precision Floating-point support (core) Denormals No Infinity and NANs Yes Round to nearest Yes Round to zero No Round to infinity No IEEE754-2008 fused multiply-add No Support is emulated in software No Correctly-rounded divide and sqrt operations No Double-precision Floating-point support (n/a) Address bits 32, Little-Endian Global memory size 1073741824 (1024MiB) Error Correction support No Max memory allocation 751619276 (716.8MiB) Unified memory for Host and Device No Minimum alignment for any data type 128 bytes Alignment of base address 131072 bits (16384 bytes) Global Memory cache type None ##################################################################### Image support No #################################################################### Local memory type Local Local memory size 32768 (32KiB) Max constant buffer size 751619276 (716.8MiB) Max number of constant args 15 Max size of kernel argument 1024 Queue properties Out-of-order execution No Profiling Yes Profiling timer resolution 0ns Execution capabilities Run OpenCL kernels Yes Run native kernels No Device Available Yes Compiler Available Yes Device Extensions cl_khr_byte_addressable_store cl_khr_global_int32_base_atomics cl_khr_global_int32_extended_atomics cl_khr_local_int32_base_atomics cl_khr_local_int32_extended_atomics NULL platform behavior clGetPlatformInfo(NULL, CL_PLATFORM_NAME, ...)
