[PATCH v2 2/2] NTB: PCI Quirk to Enable Switchtec NT Functionality with IOMMU On

2018-05-23 Thread dmeyer
From: Doug Meyer Here we add the PCI quirk for the Microsemi Switchtec parts to allow DMA access via non-transparent bridging to work when the IOMMU is turned on. This exclusively addresses the ability of a remote NT endpoint to perform DMA accesses through the locally enumerated NT endpoint. Ot

[PATCH v2 1/2] NTB: Migrate PCI Constants to Cannonical PCI Header

2018-05-23 Thread dmeyer
From: Doug Meyer This is the first of two patches to implement a PCI quirk which will allow the Switchtec NTB code to work with the IOMMU turned on. Here, the Microsemi Switchtec PCI vendor and device ID constants are moved to the canonical location in pci_ids.h. Also, Microsemi class constants

From: Doug Meyer This resolves a bug which may incorrectly configure the peer host's LUT for shared memory window access. The code was using the local host's first BAR number, rather than the peer hosts's first BAR number, to determine what peer NT control register to program. The bug will cause

The kernel always says: ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx at boot time. How would I know if it's safe to say idebus=66? The documentation is fairly vague on this. Thanks, Dave -- David M. Meyer [EMAIL PROTECTED] - To unsubscribe from this li
