Hello, Does vmalloc_to_page() returns contiguous physical memory ? I ask becuase I see that its return value is used for DMA and DMA uses contiguous memory. see here: https://elixir.bootlin.com/linux/latest/source/drivers/mtd/nand/onenand/samsung.c#L657 Yet, in vmalloc_to_page implementation: https://elixir.bootlin.com/linux/v4.5/source/mm/vmalloc.c#L234 it does not seem that it creates a contiguous allocation.
Thank you, ranran _______________________________________________ Kernelnewbies mailing list [email protected] https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
