more memory needed with acceleration card 0x3b and Arria 10 v1.2.1 devstack
Hello, I am using Arria 10 for the dma_afu sample. I am running into a memory limitation issue when I try to run the executable. See messages below. u69703@s005-n002:~/work$ lspci | grep accel 3b:00.0 Processing accelerators: Intel Corporation Device 09c4 @s005-n002:~/work/dma_afu/sw$ ./fpga_dma_test 0 Running test in HW mode Error fpgaDmaOpen: no memory Error fpgaDmaClose: invalid parameter736Views0likes2CommentsRe: DMA example Arria 10 PAC
Folks, What was the solution to this issue? I am having the same problem. From this ticket, it is not clear how the issue got resolved? Ofcourse, I am unable to run in sudo mode. s005-n002:~/A10_RTL_AFU/dma_afu/sw$ sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-\ 2048kB/nr_hugepages" Dear User, this server does not allow you to run "sudo". If you need to install a dependency, please put it in your home directory. * For autotools, you can do it with "./configure --prefix=~/my-path" * For Python packages, use "pip install <package_name> --user" or create a Conda environment.2KViews0likes0CommentsError running host program fpga_dma_test
I am following instructions to do the following exercise. https://github.com/intel/FPGA-Devcloud/tree/master/main/QuickStartGuides/RTL_AFU_Program_PAC_Quickstart/Arria10 I am able to follow and execute instructions until compiling the host program but when I try to run the host executable I get the following error. @s005-n002:~/A10_RTL_AFU/dma_afu/sw$ ./fpga_dma_test 0 Running test in HW mode Error fpgaDmaOpen: no memory Error fpgaDmaClose: invalid parameter994Views0likes1Comment
