Take a look at https://github.com/Xilinx/dma_ip_drivers/issues/262. You will need to change the code after clone yourself..

If you used that commit as-is its code changes are likely not kicking in because they pertain kernel versions 6.x and are guarded by the #defines. Looking at your compile output you are running 5.14 (with backported code from 6.x it seems).

Try removing the #defines from the commit such that the code for 6.x remains.

notooth1 commented 1 month ago

I do not see the #defines in the commit.

hinxx commented 1 month ago

Sorry, I meant #if/#ifdef blocks.

I manually added the code changes and got some errors:

Progress.

If you take a look at the same commit, where you took the code from, there are couple of more files you might need to change.

notooth1 commented 1 month ago

Is there a patch file to apply all the commits? I am unable to change all the commit code manually.

hinxx commented 1 month ago

There are 4-5 lines of code you need to change across three files. I think that is a really small patch to do manually.

Nevertheless, this post https://stackoverflow.com/questions/6188591/download-github-pull-request-as-unified-diff#6188624 explains how to get a diff/patch file from a PR or commit on github. Beware that after you apply the patch, you will need to manually deal with the #if/#ifdef lines that were added by the patch.

notooth1 commented 1 month ago

I followed the post, but it did not work:

$ git config pull.rebase true

$ git pull origin pull/240/head
From https://github.com/Xilinx/dma_ip_drivers
 * branch            refs/pull/240/head -> FETCH_HEAD
fatal: It seems that there is already a rebase-apply directory, and
I wonder if you are in the middle of another rebase.  If that is the
case, please try
    git rebase (--continue | --abort | --skip)
If that is not the case, please
    rm -fr ".git/rebase-apply"
and run me again.  I am stopping in case you still have something
valuable there.
hinxx commented 1 month ago

I thougt you were after the patch out of commit. That is what the link I provided shows image

Failing at this line:

239 | vm_flags_set(vma, VMEM_FLAGS);

makes me think that this part of the 6.x kernel code was not not backported to your kernel version. What happens if you do not include this change from the commit?

In other words, keep the original line:

vma->vm_flags |= VMEM_FLAGS;
notooth1 commented 1 month ago

This fixed the issue: vma->vm_flags |= VMEM_FLAGS; and I faced other errors:

I guess what you're seeing is similar to issues observed as so far: a) the kernel 6.x code was ported to your kernel (you need to take the code changes in the PR/commit), or b) the kernel 6.x code was NOT ported to your kernel (you need to keep the original code)

Hard to say which is it going to be, case by case, but trial and error approach, as performed so far, should work for the outstanding errors. Good luck!

ate-wang commented 2 weeks ago

I see your recovery is very good, can I ask you a question? I need to compile the xdma driver in the Kylin V10 system. Has anyone adapted the xdma driver in Kylin? I have a problem now. When the host computer operates pcie xdma, the system will freeze. After checking the log, I found that pcie is stuck. What is the situation when pcie (pcie ff) is stuck? Have you encountered this before?
