udmabuf at fixed physical address in linux x86 #93

Open

Udmabuf has been working very well for us. But it is loading at different spots every time after reboot as we use insmod command.

There is now a requirement to load the udmabuf at the same address everytime.
How do we accomplish that?

Operating system: linux
Kernel version: 5.3

Thanks

Owner

Thanks for your issue.

For arm/arm64 you can assign it to a fixed address by the device tree,
but unfortunately for x86 there is no way to do that.
