ERRORs when install xdma driver on Ubuntu #59

Closed Lumpyzc closed 3 years ago

Hi,everyone! I have got a problem when I attempt to install xdma driver on my Ubuntu server. Please give me some advice!!!! My linux system is Ubuntu 18.04
kernel is 4.15.0-132-generic

firstly I download the .zip file from here and then install the driver like what the usage says; unfortunately ,when I “cd xdma” and “make install” I meet the first problem as below:

_At main.c:160:

then I use the method #39 gives cd /usr/src/linux-headers-$(uname -r)/certs sudo openssl req -new -x509 -newkey rsa:2048 -keyout signing_key.pem -outform DER -out signing_key.x509 -nodes -subj "/CN=Owner/"

then I got that like below shows:

Can't load /root/.rnd into RNG 140138494010560:error:2406F079:random number generator:RAND_load_file:Cannot open file:../crypto/rand/randfile.c:88:Filename=/root/.rnd Generating a RSA private key .......................................+++++ ..................+++++ writing new private key to 'signing_key.pem'

I DONT know what that means and then make install again,the SSL problem gone missing !

then I do "cd tools" and "make" the result is :

cc -c -std=c99 -o reg_rw.o reg_rw.c -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE cc -o reg_rw reg_rw.o cc -c -std=c99 -o dma_to_device.o dma_to_device.c -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE In file included from /usr/include/assert.h:35, from dma_to_device.c:13: /usr/include/features.h:184:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp] 184 | # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" | ^~~ cc -lrt -o dma_to_device dma_to_device.o -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE cc -c -std=c99 -o dma_from_device.o dma_from_device.c -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE In file included from /usr/include/assert.h:35, from dma_from_device.c:13: /usr/include/features.h:184:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp] 184 | # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" | ^~~ cc -lrt -o dma_from_device dma_from_device.o -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE cc -c -std=c99 -o performance.o performance.c -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE cc -o performance performance.o -D_FILE_OFFSET_BITS=64 -D_GNU_SOURCE -D_LARGE_FILE_SOURCE

then I began to "modprobe xdma" another problem appeared as shown below:

modprobe: FATAL: Module xdma not found in directory /lib/modules/4.15.0-132-generic

I also tried to "cd tests" and "./load_driver.sh" BUT it went wrong:

Loading xdma driver...insmod: ERROR: could not insert module ../xdma/xdma.ko: Invalid module format Error: Kernel module did not load properly. FAILED

Please give me some advice !!!

BEST REGARDS!!
