I am porting our PCIe device driver to Jetpack 3.2 TX1.
When I use the API of “dma_alloc_coherent()” to allocate the memory, and use “virt_to_page()” to mapping the memory page.
It will get error page address.
Because, When I use this page address for “SetPageReserved()”, it will show the kernel exception.
But this code use on Jetpack 2.3.1, it will work.
Anyone have ideas ?
