Hello Tomasz, Laurent,
I have printed some logs during the dmabuf export and attach for the SGT
issue below. Please find it in the attachment. I hope it will be useful.

Hi Subash,
Could you post the code of vb2_dc_pages_to_sgt with all printk in it.
It will help us avoid guessing where and what is debugged in the log.
Moreover, I found a line 'size=4294836224' in the log.
It means that size is equal to -131072 (!?!) or there are some invalid
conversions in printk

Hi Thomasz,
I have extended the MFC-FIMC testcase posted by Kamil sometime ago to
sanity test the UMM patches. This test is multi-threaded(further
explanation for developers who may not have seen it yet), where thread
one parses the encoded stream and feeds into the codec IP driver(aka

Hello Thomasz, Laurent,
I found an issue in the function vb2_dc_pages_to_sgt() below. I saw that
during the attach, the size of the SGT and size requested mis-matched
(by atleast 8k bytes). Hence I made a small correction to the code as
below. I could then attach the importer properly.

Hi Subash,
Could you provide a detailed description of a test case
that causes a failure of vb2_dc_pages_to_sgt?
