IB/ipath: Deprecate ipath driver and move to staging.

2015-08-29T02:54:49Z

It is now time for the ipath driver to begin to be phased out of the kernel. This patch moves the ipath driver from the Infiniband sub tree to the staging area where it will remain until the code is removed from the kernel in a few releases.

x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled

2015-06-18T09:23:42Z

We are burrying direct access to MTRR code support on x86 in order to take advantage of PAT. In the future, we also want to make the default behaviour of ioremap_nocache() to use strong UC, use of mtrr_add() on those systems would make write-combining void. In order to help both enable us to later make strong UC default and in order to phase out direct MTRR access code port the driver over to arch_phys_wc_add() and annotate that the device driver requires systems to boot with PAT disabled, with the 'nopat' kernel parameter. This is a workable compromise given that the ipath device driver powers the old HTX bus cards that only work in AMD systems, while the newer IB/qib device driver powers all PCI-e cards. The ipath device driver is obsolete, hardware is hard to find and because of this its a reasonable compromise to require users of ipath to boot with 'nopat'. Signed-off-by: Luis R.

IB/ipath: Remove support for QLogic PCIe QLE devices

2010-05-24T05:14:25Z

The ib_qib driver is taking over support for QLogic PCIe QLE devices, so remove support for them from ib_ipath. The ib_ipath driver now supports only the obsolete QLogic Hyper-Transport IB host channel adapter (model QHT7140). Signed-off-by: Ralph Campbell Signed-off-by: Roland Dreier

IB/ipath: Remove dependency on PCI_MSI || HT_IRQ

2008-04-22T01:19:14Z

Before IBA7220 support was added, the ipath driver didn't support any hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the IBA7220 can generate INTx interrupts, so it makes sense to allow the driver to be build even if PCI_MSI=n and HT_IRQ=n. Signed-off-by: Roland Dreier

IB: Use menuconfig for InfiniBand menu

Change Kconfig objects from "menu, config" into "menuconfig" so that the user can disable the whole feature without having to enter the menu first. Signed-off-by: Jan Engelhardt Signed-off-by: Andrew Morton Signed-off-by: Roland Dreier

IB/ipath: Depend on CONFIG_NET

[PATCH] IB/ipath - fix driver build for platforms with PCI, but not HT

2006-11-16T19:43:37Z

The PCI Express and Hypertransport chip-specific source files should only be built when the kernel has the capability of actually compiling them. This fixes the driver build on, for example, ia64.
