Linux Driver Compilation Errors #26

Closed buttercutter closed 6 years ago

buttercutter commented 6 years ago

During linux driver compilation, I have such following errors https://gist.github.com/anonymous/8c2f7fd050696f6986ba22750c57fe67

I fixed these compilation issues in my fork: https://github.com/marzoul/riffa/ With my fixes the Riffa driver compiles and works fine with Linux up to 4.14. There is a pull request to merge these fixes into main Riffa repo: https://github.com/KastnerRG/riffa/pull/18 But the main Riffa author has a life and said he can't merge without proper testing etc. Please give it a try and say how it works on your side.

I tried your repo, but I am facing the following problem. It seems to me that Xillybus are also using the same file as RIFFA.

@marzoul I fixed the previous issue above and can run the demo c code without any problem.

However, when I compile the c code again today, I have the following error:

I have rebooted the computer and tried another PCIe slot, the driver is still not loaded at startup. I suspect my Altera DE4 hardware is not detected at all.

Could anyone advise ?

buttercutter commented 6 years ago

The hardware detection issue seems to be intermittent.

Now, my computer can detect my Altera DE4.

However, using the original demo loopback c and verilog code, I have the following:

I have also verified using golden bitstream from https://github.com/KastnerRG/riffa/blob/master/fpga/altera/de4/DE4Gen2x8If128/bit/DE4Gen2x8If128.sof and it resulted in the same data integrity check error.

I tried to debug the testutil.c code using gdb with no apparent success:

(gdb) run testutil 2 0 1 1000 Starting program: /home/phung/Documents/fpga_overlay/riffa/c_c++/linux/x64/test_apps/testutil testutil 2 0 1 1000 Number of devices: 1 0: id:0 0: num_chnls:1 0: name:0000:06:00.00 0: vendor id:1172 0: device id:0004 [Inferior 1 (process 2802) exited normally] (gdb)

I suspect that this could be the linux driver issue.

Since I have enabled debug support ("make debug") during linux driver compilation, could anyone guide me how to debug this problem ?

Edit: problem solved. it should be "testutil 2 0 0 1000"

@marzoul I am using your patch with linux kernel 4.13.0-37-generic

However, I am facing intermittent hardware detection issue which seems to affect the driver autoload during reboot/startup. Could you advise ?

Edit: When I drop my linux kernel version to 4.13.0-36-generic , linux driver is loaded at reboot/startup

@promach I don't know what could happen. The riffa driver has always reliably detected my pre-programmed board when booting. But I tried to reboot the machine the least possible because my machine took ages to boot. Maybe there is a link to pull request https://github.com/KastnerRG/riffa/pull/17 ? But they don't indicate how bad the crash is. On my side I've faced very rare crash issues where the system logs quite clearly indicated the riffa driver was the cause. This was when using a Xilinx VC709 board, if vendor matters. Sufficiently rare (2-3 months between crashes) to prevent investigating, though. I didn't try https://github.com/KastnerRG/riffa/pull/17.

@promach Even if the driver is not loaded at boot, is the board detected reliably when you axplicitly ask the kernel for PCIe devices rescan after boot ? Could be an easy workaround.

@marzoul

I have solved this. Driver will not be auto-loaded even there is a minor difference in linux kernel version, in my case 4.13.0.36 vs 4.13.0.37

@marzoul @promach an error occurred in executing sudo make command, I don't konw why，in ubuntu 20.04 图片
