3.14.28 Kernel: unmap_single() and dma_map_single()

norishinozaki — Wed, 16 Dec 2015 23:36:55 GMT

Hello,

My customer is asking following questions about 3.14.28_1.0.1 kernel.

1. unmap_single() and dma_map_single() are supported in i.MX6

2. Max size can be allocated by kmallc(4MB?)

Knowing NXP is using Linaro Kernel, but can anybody answer these questions?

Best regards,

Nori Shinozaki
