Hi,
In a network driver, I tried to allocate memory for DMA buffer of length 132 KB and the call (kmalloc()) failed. Hacking through kmalloc.c, I found that it does not allow allocating memory more than (128K - 24) bytes, if the page size is 4KB.
Me questions are -
1. Why is that limitation ? 2. Is there any way to allocate 132 KB memory (physically contiguous) ?
My system has 32 MB memory.
Any help is appreciated.
Thanx in advance, - Somnath.
