2015-09-07NTB: Fix range check on memory window indexAllen Hubbe1-1/+1
The range check must exclude the upper bound. Signed-off-by: Allen Hubbe <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-09-07NTB: Improve index handling in B2B MW workaroundAllen Hubbe1-6/+16
Check that b2b_mw_idx is in range of the number of memory windows when initializing the device. The workaround is considered to be in effect only if the device b2b_idx is exactly UINT_MAX, instead of any index past the last memory window. Only print B2B MW workaround information in debugfs if the workaround is in effect. Signed-off-by: Allen Hubbe <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-09-07NTB: Add PCI Device IDs for Broadwell XeonDave Jiang1-0/+15
Adding PCI Device IDs for B2B (back to back), RP (root port, primary), and TB (transparent bridge, secondary) devices. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Add split BAR output for debugfs statsDave Jiang1-15/+68
When split BAR is enabled, the driver needs to dump out the split BAR registers rather than the original 64bit BAR registers. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Change WARN_ON_ONCE to pr_warn_once on unsafeDave Jiang1-8/+16
The unsafe doorbell and scratchpad access should display reason when WARN is called. Otherwise we get a stack dump without any explanation. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Print driver name and version in module initDave Jiang1-0/+4
Printouts driver name and version to indicate what is being loaded. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Rename Intel code names to platform namesDave Jiang1-310/+310
Instead of using the platform code names, use the correct platform names to identify the respective Intel NTB hardware. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Use NUMA memory in Intel driverAllen Hubbe1-6/+12
Allocate memory for the NUMA node of the NTB device. Signed-off-by: Allen Hubbe <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Add parameters for Intel SNB B2B addressesAllen Hubbe1-19/+58
Add module parameters for the addresses to be used in B2B topology. Signed-off-by: Allen Hubbe <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Check the device ID to set errata flagsDave Jiang1-5/+44
Set errata flags for the specific device IDs to which they apply, instead of the whole Xeon hardware class. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Enable link for Intel root port mode in probeDave Jiang1-0/+10
Link training should be enabled in the driver probe for root port mode. We should not have to wait for transport to be loaded for this to happen. Otherwise the ntb device will not show up on the transparent bridge side of the link. Signed-off-by: Dave Jiang <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-04NTB: Split ntb_hw_intel and ntb_transport driversAllen Hubbe1-1426/+1647
Change ntb_hw_intel to use the new NTB hardware abstraction layer. Split ntb_transport into its own driver. Change it to use the new NTB hardware abstraction layer. Signed-off-by: Allen Hubbe <[email protected]> Signed-off-by: Jon Mason <[email protected]>
2015-07-02NTB: Move files in preparation for NTB abstractionAllen Hubbe1-0/+1894
This patch only moves files to their new locations, before applying the next two patches adding the NTB Abstraction layer. Splitting this patch from the next is intended make distinct which code is changed only due to moving the files, versus which are substantial code changes in adding the NTB Abstraction layer.
