Significance of the value of MAX_ORDER

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

In my quest to get the kernel to allocate a contiguous 4098kB chunk of
memory (for a large framebuffer), I found out that the MAX_ORDER macro
was the reason memory allocation failed (4098kB -> 8192kB = order 11).
So I raised MAX_ORDER to 12 and allocation succeeds.

My question now is, what is the significance of the value 11 assigned to
MAX_ORDER?  Is it safe to change it?

Thanks,
	Manuel Lauss
