Can't compile ion.c for hddl on Ubuntu 18.04 (5.3.0 kernel)

[JoshDavisNC]

When I try to run ${HDDL_INSTALL_DIR}/install_IVAD_VPU_dependencies.sh, I get the following errors. I am using Ubuntu 18.04 with the 5.3.0-26 kernel. Is there some step I missed?

I found the problem. Somewhere between the 4.11.0 and 5.3.0 kernels, the type of vm_operations_struct.fault changed from int to vm_fault_t (typedef for unsigned int). Adding the two bolded lines below at ion.c:1164 fixed the error.

#if LINUX_VERSION_CODE < KERNEL_VERSION(4, 11, 0)
static int ion_vm_fault(struct vm_area_struct *vma, struct vm_fault *vmf)
#elif LINUX_VERSION_CODE >= KERNEL_VERSION(5, 3, 0)
static vm_fault_t ion_vm_fault(struct vm_fault *vmf)
#else
static int ion_vm_fault(struct vm_fault *vmf)
#endif

This got it to compile, but it's not working. The hddldaemon fails with a SIGSEGV and dumps core. The error from the crash report is "Disassembly: => 0x20:   Cannot access memory at address 0x20". I can attach the crash report if that's helpful.

Prior to the core dump, I see these errors, not sure if related:

Failed to use HDDL BSL configure file in ${HDDL_INSTALL_DIR}/config,
it may not exist or format is wrong
Error is:	BSL_ERROR_NO_DEVICE_FOUND

Any ideas how I can fix the BSL_ERROR_NO_DEVICE_FOUND error and how I can get the hddldeamon to run?

[JoshDavisNC]

Any ideas?

Hi JoshDavisNC,

Please attach the entire log and I can take a look. 

• Which HDDL card are you using?
• Can you confirm the ${HDDL_INSTALL_DIR}/config/bsl.json exists?

Regards,

Jesus

[JoshDavisNC]

Thank you for looking at this.

It exists, and is attached here as bsl.json_.txt.

Attached is the output from running demo_squeezenet_download_convert_run.sh -d HDDL from the demo folder. The process crashes with SYSSEGV "Disassembly: => 0x20:   Cannot access memory at address 0x20" after the last line of output. The crash report is also attached.

Edited to add: Everything works fine if I use GPU or MYRIAD as the device.

Hi JoshDavisNC,

I tested the HDDL plugin on Ubuntu 18.04 with Kernel 5.3 using a Mustang-V100-MX8 and saw the same error you are running into. Using the same system with Kernel 4.15 did not have this issue. I will check with the development team, however, it's likely Kernel 5.3 is not supported by the HDDL plugin.

Regards,

Jesus

Hi JoshDavisNC,

Apologize for the delay in my response, the error is caused by a compatibility issue with kernel version 5.3. This should be fixed in the next release, as a workaround please try disabling the ION driver.

sudo mv /lib/modules/$(uname -r)/kernel/drivers/myd/myd_ion.ko  /lib/modules/$(uname -r)/kernel/drivers/myd/myd_ion.ko.backup

sudo depmod -a

it does not seem to have been fixed in V3 either but got it up and running by using

1sudo mv /lib/modules/$(uname -r)/kernel/drivers/myd/myd_ion.ko  /lib/modules/$(uname -r)/kernel/drivers/myd/myd_ion.ko.backup

2 

3sudo depmod -a

we would like to know if pytorch  which are local   can be imported and  converted  in DL

which is not in the Import a local that is a which is not in the
