| |
Currently NIX, NPA queue context memory is being allocated using GFP_KERNEL flag which inturns allocates from memory reserved for CMA_DMA. Sizing CMA_DMA memory is getting difficult due to this dependency, the more number of interfaces enabled the more the CMA_DMA memory requirement.
To address this issue, GFP_KERNEL flag is replaced with GFP_ATOMIC, with this memory will be allocated from unreserved memory.
