Hi,
I am working on 2.4.20 kernel.
I need to allocate memory with kmalloc.
kmalloc fails because i want to allocate more than 128kb. How to handle
this issue.
Please help me in this regard.
How i can allocate memory of size equal to 1Mb with kmalloc or any other
function (2.4 kernel)
kmalloc() allocates physically contiguous pages. 1M is a hell of a lot
of contig pages to ask for. I doubt you can get that much except at
early boot. But, if the pages don't actually need to be physically
contiguous, then you can use vmalloc() - it'll give you a virtually
contiguous range but the pages are not nessesarily physically
contiguous.
Why do you need this much btw?
