Some of those amd changes aren't "fixes". They are some major code changes.

We're still in the merge window, so I'm letting it slide, but calling
then "fixes" really stretches things. They are fixes exactly the same
way completely new development can "fix" things.

From: Arthur Marsh <arthur.marsh@internode.on.net>

Hi, the "drm fixes for 6.1-rc1" commit caused the amdgpu module to fail
with my Cape Verde radeonsi card.

I haven't been able to bisect the problem to an individual commit, but
attach a dmesg extract below.

I'm happy to supply any other configuration information and test patches.

Arthur.

Can you try reverting: it's the only think I can spot that might
affect a card that old since most changes in that request were for
display hw you don't have.

    drm/amdgpu: Fix VRAM BO swap issue

    DRM buddy manager allocates the contiguous memory requests in
    a single block or multiple blocks. So for the ttm move operation
    (incase of low vram memory) we should consider all the blocks to
    compute the total memory size which compared with the struct
    ttm_resource num_pages in order to verify that the blocks are
    contiguous for the eviction process.

    v2: Added a Fixes tag
    v3: Rewrite the code to save a bit of calculations and
        variables (Christian)

    Fixes: c9cad937c0c5 ("drm/amdgpu: add drm buddy support to amdgpu")

Regards,

Arthur.

Hi Arun,

the hw generation doesn't matter. This error message here:

amdgpu: Move buffer fallback to memcpy unavailable

indicates that the detection of linear buffers still doesn't work as 
expected or that we have a bug somewhere else.

Maybe the limiting when SDMA moves are not available isn't working 
correctly?

Regards,
Christian.

It is a CAPE_VERDE, so maybe something with the SI UVD memory limitations?

Yeah, good point. Could be that we try to move something into the UVD 
memory window and that something isn't allocated linearly.

Arun can you trace the allocation and make sure that all kernel 
allocations have the CONTIGUOUS flag set?

Thanks,
Christian.

Hi Christian,

Looks like we have to exit the loop if there are no blocks to compare.
May be that's why the function returns false.

@Arthur Marsh Could you please test the attached patch.

Thanks,
Arun

Thanks Arunpravin, your patch applied to the 6.1-rc1 code built a kernel that loaded the amdgpu module on my pc with Cape Verde GPU card with no problems.

Regards,

Arthur.
