Hi Christoph,
 
Im able to reserve CMA memory during boot up in AMD.
But how can i use/allocate that memory in my driver.
 
I dont know if this is the right forum to ask such question.
Any help will be appriciated.
 
Thanks and regards,
Sathya

I tried to apply the patch (AMD IOMMU driver to use dma-iommu) to linux kerenl 
5.1.15 but it gives me some errors. 
Downloaded the patch from https://patchwork.ozlabs.org/patch/1096015/

Is this the right way im doing?

Please let me know.

Thanks,
Sathya
