In have a sdram of size 9MB which i would map to kernel space (ioremap woul= d do that ) the whole 9 MB kernel virtual memory i need to map to the application , the application would read when driver has complited writing and vice versa this implimentation would be in a circular buffer type. The size of my RAM is 128 MB=20 Sylvain Joyeau wrote:
=20 Misbah, =20 Please, give some more details about your application: the answer(s) heavily depends on the kind of memory you want to allocate: contiguous (implied in DMA purpose) or not (for process memory sharing only). =20 -- sj =20 =20 2008/7/17 Misbah khan [off-list ref]:quoted
Hi all, I need to allocate 9 MB of memory in to the kernel space which i need to mmap for the application to access. I need to know what could be the best possible way of doing the same. Please share your experience in this regard . Thank you in advance ----Misbah <>< -- View this message in context: http://www.nabble.com/how-to-allocate-9MB-of-memory-in-kernel---tp185030=
