When remote files are counted in get_files_count, without using SSH, the code returns 0 because there is a colon prepended to $LOC. $VPATH should have been used instead of $LOC.

When running ntb_test, the script tries to run the ntb_perf test immediately after probing the modules. Since adding multi-port support, this fails seeing the new initialization procedure in ntb_perf can not complete instantly. To fix this we add a completion which is waited on when a test is started. In this way, run can be written any time after the module is loaded and it will wait for the initialization to complete instead of sending an error.

Legacy drivers do not have port numbers (but is reliably only two ports) and was broken by the recent commit that added mult-port support to ntb_perf. This is especially important to support the cross link topology which is perfectly symmetric and cannot assign unique port numbers easily. Hardware that returns zero for both the local port and the peer should just always use gidx=0 for the only peer.

This commit fixes pingpong support for existing drivers that do not implement ntb_default_port_number() and ntb_default_peer_port_number(). This is required for hardware (like the crosslink topology of switchtec) which cannot assign reasonable port numbers to each port due to its perfect symmetry. Instead of picking the doorbell to use based on the the index of the peer, we use the peer's port number. This is a bit clearer and easier to understand.

When the commit adding ntb_default_port_number() and ntb_default_peer_port_number() entered the kernel there was no users of it so it was impossible to tell what the API needed. When a user finally landed a year later (ntb_pingpong) there were more NTB topologies were created and no consideration was considered to how other drivers had changed. Now that there is a user it can be fixed to provide a sensible default for the legacy drivers that do not implement ntb_{peer_}port_number(). Seeing ntb_pingpong doesn't check error codes returning EINVAL was also not sensible. Patches for ntb_pingpong and ntb_perf follow (which are broken otherwise) to support hardware that doesn't have port numbers. This is important not only to not break support with existing drivers but for the cross link topology which, due to its perfect symmetry, cannot assign unique port numbers to each side.

Commit 417cf39c ("NTB: Set dma mask and dma coherent mask to NTB devices") started using the NTB device for DMA allocations which was turns out was wrong. If the IOMMU is enabled, such alloctanions will always fail with messages such as: DMAR: Allocating domain for 0000:02:00.1 failed This is because the IOMMU has not setup the device for such use. Change the tools back to using the PCI device for allocations seeing it doesn't make sense to add an IOMMU group for the non-physical NTB device. Also remove the code that sets the DMA mask as it no longer makes sense to do this.

Currently, ntb->dev is passed to dma_alloc_coherent and dma_free_coherent calls. The returned dma_addr_t is the CPU physical address. This works fine as long as IOMMU is disabled. But when IOMMU is enabled, we need to make sure that IOVA is returned for dma_addr_t. So the correct way to achieve this is by changing the first parameter of dma_alloc_coherent() as ntb->pdev->dev instead.

This sorts the actual field names too, potentially causing even more chaos and confusion at merge time if you have edited the MAINTAINERS file. But the end result is a more consistent layout, and hopefully it's a one-time pain minimized by doing this just before the -rc1 release.

They are all supposed to be sorted, but people who add new entries don't always know the alphabet. Plus sometimes the entry names get edited, and people don't then re-order the entry. Let's see how painful this will be for merging purposes (the MAINTAINERS file is often edited in various different trees), but Joe claims there's relatively few patches in -next that touch this, and doing it just before -rc1 is likely the best time. Fingers crossed. This was scripted with /scripts/parse-maintainers.pl --input=MAINTAINERS --output=MAINTAINERS but then I also ended up manually upper-casing a few entry names that stood out when looking at the end result.

It will inject the #AC blindly into the guest whether the guest is prepared or not. Provide a function for guest mode which acts depending on the host SLD mode.
