Subject: DMA memory limitation?
Date: Thu, 05 Jul 2001 17:17:50 +0530	[thread overview]
Message-ID: <3B4453E6.F4342781@techmas.hcltech.com> (raw)

Hi,

Is there any limitation on DMA memory we can allocate using
kmalloc(size, GFP_DMA)? I am not able to acquire more than
14MB of the mem using this on my PCI SMP box with 256MB ram.
I think there is restriction on ISA boards of 16MB.
Can we increase it ?

thx,
Vasu
