ntb: ntb_hw_intel: link_poll isn't clearing the pending status properly

2017-02-17T04:11:26Z

On Skylake hardware, the link_poll isn't clearing the pending interrupt bit. Adding a new function for SKX that handles clearing of status bit the right way. Signed-off-by: Dave Jiang Fixes: 783dfa6c ("ntb: Adding Skylake Xeon NTB support") Signed-off-by: Jon Mason

ntb_transport: Pick an unused queue

Fix typo causing ntb_transport_create_queue to select the first queue every time, instead of using the next free queue. Signed-off-by: Thomas VanSelus Signed-off-by: Aaron Sierra Acked-by: Allen Hubbe Fixes: fce8a7bb5 ("PCI-Express Non-Transparent Bridge Support") Signed-off-by: Jon Mason

ntb: ntb_perf missing dmaengine_unmap_put

2017-02-17T04:11:26Z

In the normal I/O execution path, ntb_perf is missing a call to dmaengine_unmap_put() after submission. That causes us to leak unmap objects. Signed-off-by: Dave Jiang Fixes: 8a7b6a77 ("ntb: ntb perf tool") Signed-off-by: Jon Mason

NTB: ntb_transport: fix debugfs_remove_recursive

2017-02-17T04:10:52Z

The call to debugfs_remove_recursive(qp->debugfs_dir) of the sub-level directory must not be later than debugfs_remove_recursive(nt_debugfs_dir) of the top-level directory. Otherwise, the sub-level directory will not exist, and it would be invalid (panic) to attempt to remove it. This removes the top-level directory last, after sub-level directories have been cleaned up.

NTB: Fix 'request_irq()' and 'free_irq()' inconsistancy

'request_irq()' and 'free_irq()' should have the same 'dev_id'. Signed-off-by: Christophe JAILLET Acked-by: Dave Jiang Signed-off-by: Jon Mason

ntb: fix SKX NTB config space size register offsets

2016-12-23T21:10:54Z

The offsets for the SZ registers are wrong. Updated. Signed-off-by: Dave Jiang Reported-by: Sandeep Mann Tested-by: Zachary Ross Signed-off-by: Jon Mason

ntb_transport: Limit memory windows based on available, scratchpads

2016-12-23T21:10:35Z

When the underlying NTB H/W driver advertises more memory windows than the number of scratchpads available to setup MW's, it is likely that we may end up filling the remaining memory windows with garbage. So to avoid that, lets limit the memory windows that transport driver can setup based on the available scratchpads. Signed-off-by: Shyam Sundar S K Acked-by: Allen Hubbe Signed-off-by: Jon Mason

NTB: Register and offset values fix for memory window

2016-12-23T21:09:18Z

Due to incorrect limit and translation register values, NTB link was going down when the memory window was setup. Made appropriate changes as per spec. Fix limit register values for BAR1, which was overlapping with the BAR23 address. Signed-off-by: Shyam Sundar S K Acked-by: Allen Hubbe Signed-off-by: Jon Mason

NTB: add support for hotplug feature

2016-12-23T21:09:15Z
