Subject: dma_pool_alloc restrict < 4GB address
Date: Wed, 12 Nov 2008 14:14:24 -0800 (PST) [thread overview]
Message-ID: <231988.14599.qm@web32401.mail.mud.yahoo.com> (raw)
Hi,
Is there anyway to restrict the returned bus address(dma address) from dma_poll_alloc to < 4GB ?
The function returns a dma address(of type dma_addr_t). Is there anyway I can ensure to restrict it to < 4B address.
I guess we can do that in pci_alloc_consistent as by default it returns 32bit address.
with regards,
Anil
