DMA memory allocation --how to more than 1 MB

[Srinivas G.]

Hi All,

I have a doubt about allocating the DMA memory using kmalloc OR
__get_dma_pages OR pci_alloc_consistent. I was unable to allocate the
memory greater than 1 MB using any one of the above memory functions. 

Is there any other method which will allocate the DMA memory greater
than 1 MB?

My system configuration is: Red Hat 7.3 with 2.4.18-3 kernel version on
IA32 platform. 

Thanks and regards,
Srinivas G
