All its callers depends on the return value of -ENOBUFS to reallocate a bigger buffer and retry the receiving. So there's no need to call pr_err() here since it was not a real issue, otherwise syslog will be flooded by this false warning. Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by:

GenWQE used to call pci_enable_msi_block to allocate a desired number of MSI's. If that was not possible pci_enable_msi_block returned with a smaller number which might be possible to allocate. GenWQE then called pci_enable_msi_block with that number. Since commit a30d0108 "GenWQE: Use pci_enable_msi_exact() instead of pci_enable_msi_block()" pci_enable_msi_exact is used which fails if the desired number of MSI's was not possible to allocate. Change GenWQE to use pci_enable_msi_range to restore the old behavior. Signed-off-by:

Currently, in the event of a fatal hardware error, the driver tries a recovery procedure that calls pci_reset_function() to reset the card. This is not sufficient in some cases, needing a fundamental reset to bring the card back. This patch implements a call to the platform fundamental reset procedure on the error recovery path if GENWQE_PLATFORM_ERROR_RECOVERY is enabled. This is implemented by default only on PPC64, since this can cause problems on other archs, e.g. zSeries, where the platform has its own recovery procedures, leading to a potencial race conditition. For these cases, the recovery is kept as it was before. Signed-off-by:

This patch implements the callbacks and functions necessary to have EEH recovery support. It adds a config option to enable or disable explicit calls to trigger platform specific mechanisms on error recovery paths. This option is enabled by default only on PPC64 systems and can be overritten via debugfs. If this option is enabled, on the error recovery path the driver will call pci_channel_offline() to check for error condition and issue non-raw MMIO reads to trigger early EEH detection in case of hardware failures. This is necessary since the driver MMIO helper funtions use raw accessors. Signed-off-by:

This patch adds an interface on sysfs for userspace to request a card bitstream reload. It sets the appropriate register and try to perform a fundamental reset on the PCIe slot for the card to reload the bitstream from the chosen partition. Signed-off-by:

nhi->rx_rings does not have type as struct tb_ring *, as it is a double pointer so the elements of the array should have pointer type, not structure type.

commit 94859308 "w1: new w1_ds2406 driver" added a new driver that uses the crc16 library, but didn't ensure that the core is there. This adds the necessary Kconfig statements, just like we have it for other w1 drivers. Reported-by:

Some preliminary work at making use of this driver led me to implement CRC-16 checks on read and write to deal with the occasional glitchiness of the 1-Wire bus. The revised driver (attached) returns an I/O error if the CRC check fails. When reading the chip's state, either you get a valid indication or you get an I/O error. When changing its state, either the change is successful or an I/O error is returned. Signed-off-by:

According to the i.MX reference manual, the read/write bit operations takes from 60 us to 120 us. This patch optimizes mxc_w1_ds2_touch_bit() function to use proper value for such delay. Nevertheless, a small margin for the timeout has been added for the case if clock frequency is inaccurate. Signed-off-by:

According to the i.MX reference manual, the reset procedure and "presence" pulse takes 511 and 512 us, respectively. Measurement for i.MX27 is about 1100 us. There is no need to wait Reset+Presence more than this time. This patch optimizes mxc_w1_ds2_reset_bus() function to use proper value for delay after w1 bus reset.

Fix issues observed with the Startech docking station: Fix the type of the route parameter in tb_ctl_rx. It should be u64 and not u8 (which only worked for short routes). A thunderbolt cable contains two lanes. If both endpoints support it a connection will be established on both lanes. Previously we tried to scan below both "dual link ports". Use the information extracted from the drom to only scan behind ports with lane_nr == 0. Endpoints with more complex thunderbolt controllers have some of their ports disabled (for example the NHI port or one of the HDMI/DP ports). Accessing them results in an error so we now ignore ports which are marked as disabled in the drom. Signed-off-by:

All Thunderbolt switches (except the root switch) contain a drom which contains information about the device. Right now we only read the UID. Add code to read and parse this drom. For now we are only interested in which ports are disabled and which ports are "dual link ports" (a physical thunderbolt port/socket contains two such ports). Signed-off-by:
