2007-10-11[POWERPC] Remove more iSeries-specific stuff from vio.cStephen Rothwell1-1/+23

2007-10-11[POWERPC] Remove iSeries_vio_devStephen Rothwell1-0/+30
It was only being used to carry around dma_iommu_ops and vio_iommu_table which we can use directly instead. This also means that vio_bus_device doesn't need to refer to them either.

2006-12-04[POWERPC] Refactor 64 bits DMA operationsBenjamin Herrenschmidt1-8/+4
This patch completely refactors DMA operations for 64 bits powerpc. 32 bits is untouched for now. We use the new dev_archdata structure to add the dma operations pointer and associated data to struct device. While at it, we also add the OF node pointer and numa node. In the future, we might want to look into merging that with pci_dn as well. The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced by a set of generic iommu and direct DMA ops (non PCI specific) that can be used by bus types. The toplevel implementation is now inline.

2006-11-01[POWERPC] Use 4kB iommu pages even on 64kB-page systemsLinas Vepstas1-9/+2
The 10Gigabit ethernet device drivers appear to be able to chew up all 256MB of TCE mappings on pSeries systems, as evidenced by numerous error messages: iommu_alloc failed, tbl c0000000010d5c48 vaddr c0000000d875eff0 npages 1 Some experimentation indicates that this is essentially because one 1500 byte ethernet MTU gets mapped as a 64K DMA region when the large 64K pages are enabled. Thus, it doesn't take much to exhaust all of the available DMA mappings for a high-speed card. This patch changes the iommu allocator to work with its own unique, distinct page size. Although the patch is long, its actually quite simple: it just #defines a distinct IOMMU_PAGE_SIZE and then uses this in all the places that matter. As a side effect, it also dramatically improves network performance on platforms with H-calls on iommu translation inserts/removes (since we no longer call it 16 times for a 1500 bytes packet when the iommu HW is still 4k). In the future, we might want to make the IOMMU_PAGE_SIZE a variable in the iommu_table instance, thus allowing support for different HW page sizes in the iommu itself.

2006-07-31[POWERPC] iseries: Constify & voidify get_property()Jeremy Kerr1-1/+1
Now that get_property() returns a void *, there's no need to cast its return value. Also, treat the return value as const, so we can constify get_property later. iseries platform changes.

2006-07-14[POWERPC] iseries: Move iommu_table_cb into platforms/iseriesMichael Ellerman1-0/+17
Although we pass the address of an iommu_table_cb to HvCallXm_getTceTableParms, we don't actually need the structure definition anywhere except in the iseries iommu code, so move the struct in there.

2006-05-24[PATCH] powerpc: remove LogicalSlot from pci_dnStephen Rothwell1-1/+4
As we now store enough information in the device_node. Also the Flags field was not used either, do remove that. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-05-24[PATCH] powerpc: remove iSeries_Global_Device_ListStephen Rothwell1-6/+9
We can now scan the list of device nodes instead. This also allows us to remove the Device_list member of struct pci_dn. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-04-29[PATCH] powerpc: kill union tce_entryOlof Johansson1-11/+10
It's been long overdue to kill the union tce_entry in the pSeries/iSeries TCE code, especially since I asked the Summit guys to do it on the code they copied from us. Also, while I was at it, I cleaned up some whitespace. Built and booted on pSeries, built on iSeries. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

2005-11-06[PATCH] ppc64: support 64k pagesBenjamin Herrenschmidt1-32/+42
Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

The only real user of this file outside platforms/iseries was drivers/net/iseries_veth.c but all it wanted was ISERIES_HV_ADDR() so we move that to abs_addr.h (and lowercase it). Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>
