|Subject:||[PATCH] Replace pci_pool with generic dma_pool|
|Date:||Fri, 30 Jan 2004 17:32:05 -0700|
All, This set of patches against 2.6.2-rc2 removes the PCI-specific pci_pool structure and replaces it with a generic dma_pool. For compatibility with existing PCI drivers, macros are provided that map pci_pool_* to dma_pool_*. This is extremely useful for architecture that have non-PCI devices but require DMA buffer pools. A good example is USB, where we've had to make some hacks in the ARM implementation of the DMA API to get around the USB's usage of the PCI DMA API and pci_pools with non-PCI device. The patch has been tested on x86, ppc, and xscale (ARM). Patch portions are posted as replies to this email. If this patch is accepted, I'll post a follow-on patch to the USB list to clean up the USB layer to only use the generic DMA functions instead of the PCI functions. ~Deepak diffstat: linux/drivers/base/Makefile | 2 linux/drivers/base/core.c | 1 linux/drivers/base/dmapool.c | 409 ++++++++++++++++++++++++++++++++++++++++++++++ linux/drivers/pci/Makefile | 2 linux/drivers/pci/probe.c | 2 linux/include/linux/device.h | 1 linux/include/linux/dmapool.h | 27 +++ linux/include/linux/pci.h | 14 - linux/drivers/pci/pool.c | 404 --------------------------------------------- 9 files changed, 448 insertions(+), 414 deletions(-) -- Deepak Saxena - firstname.lastname@example.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to email@example.com More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
