xilinx_axidma VS linux-xlnx

I recently got this kind of working, using this driver https://github.com/bperez77/xilinx_axidma. Even after using this driver I had to make changes to the auto generated device tree to get it up and running. This driver also comes with a userspace library and examples that work. I was unable to get the axidmatest.c provided by Xilinx to work.

For the DMA I found several examples by xilinx and independent folks demonstrating several way in which it can be done in linux. I started with the xilinx_dma.c driver that is provided by xilinx along with a test driver that is found here. Long story short, it didn't work. The test failed and nothing came of it.

The Framebuffer Read IP has kernel driver and you can find the device tree bindings for it here.

Has anyone used custom configurations on the Xilinx KV260 AP1302 Image co-processor? I plan to look at the different camera options for Kria KV260. The documentation is not publicly available. This was the only code I could find: https://github.com/Xilinx/linux-xlnx/blob/master/drivers/media/i2c/ap1302.c

Thank you for your response. The remote repo I was pointing to was Xilinx/linux-xlnx, but I was pointing to a branch with an older commit, which was the default version for PetaLinux 2018.3: Xilinx/linux-xlnx/tree/xlnx_rebase_v4.14

https://github.com/Xilinx/linux-xlnx the petalinux repo has some history, I don't know how long it goes back though (I am with the phone)
