2008-05-12x86: reserve dma32 early for gart fixYinghai Lu1-4/+1
we can use free_bootmem() directly. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-05-12x86_64: allocate gart aperture from 512MYinghai Lu1-1/+5
because we try to reserve dma32 early, so we have chance to get aperture from 64M. with some sequence aperture allocated from RAM, could become E820_RESERVED. and then if doing a kexec with a big kernel that uncompressed size is above 64M we could have a range conflict with still using gart. So allocate gart aperture from 512M instead. Also change the fallback_aper_order to 5, because we don't have chance to get 2G or 4G aperture.

2008-05-01x86: iommu_sac_force can become staticDmitri Vorobiev1-1/+1
The iommu_sac_force variable is needlessly defined global, and this patch makes it static. Additionally, this variable needs not be explicitly initialized.

2008-04-19x86: integrate pci-dma.cGlauber Costa1-0/+175
The code in pci-dma_{32,64}.c are now sufficiently close to each other. We merge them in pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move bad_dma_addressGlauber Costa1-0/+2
It goes to pci-dma.c, and is removed from the arch-specific files. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move dma_coherent functions to pci-dma.cGlauber Costa1-0/+81
They are placed in an ifdef, since they are i386 specific the structure definition goes to dma-mapping.h. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: merge iommu initialization parametersGlauber Costa1-0/+81
we merge the iommu initialization parameters in pci-dma.c Nice thing, that both architectures at least recognize the same parameters. usedac i386 parameter is marked for deprecation Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: merge dma_supportedGlauber Costa1-0/+44
The code for both arches are very similar, so this patch merge them. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move pci fixup to pci-dma.cGlauber Costa1-0/+18
via_no_dac provides a fixup that is the same for both architectures. Move it to pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move x86_64-specific to common code.Glauber Costa1-0/+73
This patch moves the bootmem functions, that are largely x86_64-specific into pci-dma.c. The code goes inside an ifdef. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move initialization functions to pci-dma.cGlauber Costa1-0/+25
initcalls that triggers the various possibiities for dma subsys are moved to pci-dma.c. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: unify pci-nommuGlauber Costa1-0/+8
merge pci-base_32.c and pci-nommu_64.c into pci-nommu.c Their code were made the same, so now they can be merged. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: move definition to pci-dma.cGlauber Costa1-0/+3
Move dma_ops structure definition to pci-dma.c, where it belongs. Signed-off-by: Glauber Costa <gcosta@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-04-19x86: introduce pci-dma.cGlauber Costa1-0/+14
This patch introduces pci-dma.c, a common file for pci dma between i386 and x86_64. As a start, dma_set_mask() is the same between architectures, and is placed there.
