net/mlx5e: Device's mtu field is u16 and not int

2016-05-19T00:06:36Z

[ Upstream commit 046339eaab26804f52f6604877f5674f70815b26 ] For set/query MTU port firmware commands the MTU field is 16 bits, here I changed all the "int mtu" parameters of the functions wrapping those firmware commands to be u16.

net/mlx5_core: Fix trimming down IRQ number

2016-01-31T19:29:01Z

[ Upstream commit 0b6e26ce89391327d955a756a7823272238eb867 ] With several ConnectX-4 cards installed on a server, one may receive irqn > 255 from the kernel API, which we mistakenly trim to 8bit. This causes EQ creation failure with the following stack trace: [] dump_stack+0x48/0x64 [] __setup_irq+0x3a1/0x4f0 [] request_threaded_irq+0x120/0x180 [] ? mlx5_eq_int+0x450/0x450 [mlx5_core] [] mlx5_create_map_eq+0x1e4/0x2b0 [mlx5_core] [] alloc_comp_eqs+0xb1/0x180 [mlx5_core] [] mlx5_dev_init+0x5e9/0x6e0 [mlx5_core] [] init_one+0x99/0x1c0 [mlx5_core] [] local_pci_probe+0x4c/0xa0 Fixing it by changing of the irqn type from u8 to unsigned int to support values > 255 Fixes: 61d0e73e0a5a ('net/mlx5_core: Use the the real irqn in eq->irqn') Reported-by: Jiri Pirko Signed-off-by: Doron Tsur Signed-off-by: Matan Barak Signed-off-by: David S.

net/mlx5_core: Wait for FW readiness on startup

2015-10-15T02:14:43Z

On device initialization, wait till firmware indicates that that it is done with initialization before proceeding to initialize the device. Also update initialization segment layout to match driver/firmware interface definitions. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: David S. Miller

net/mlx5_core: Add pci error handlers to mlx5_core driver

2015-10-15T02:14:42Z

This patch implement the pci_error_handlers for mlx5_core which allow the driver to recover from PCI error. Once an error is detected in the PCI, the mlx5_pci_err_detected is called and it: 1) Marks the device to be in 'Internal Error' state. 2) Dispatches an event to the mlx5_ib to flush all the outstanding cqes with error. 3) Returns all the on going commands with error. 4) Unloads the driver. Afterwards, the FW is reset and mlx5_pci_slot_reset is called and it enables the device and restore it's pci state. If the later succeeds, mlx5_pci_resume is called, and it loads the SW stack.

net/mlx5_core: Fix internal error detection conditions

2015-10-15T02:14:41Z

The detection of a fatal condition has been updated to take into account the state reported by the device or by detecting an all ones read of the firmware version which indicates that the device is not accessible. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: David S. Miller

net/mlx5_core: Use private health thread for each device

2015-10-09T14:27:49Z

Use a single threaded work queue for each device in the system instead of using one thread for any device. This is required so we can concurrently process system error handling for all the devices that need that. Signed-off-by: Eli Cohen Signed-off-by: Or Gerlitz Signed-off-by: David S. Miller

net/mlx5_core: Prepare cmd interface to system errors handling

2015-10-09T14:27:48Z

In preparation to handling system errors at the mlx5_core level, change the interface of cmd_work_handler to accept a 64 bit argument for the vector. This allows to encode a flag that signifies when the handler is called as a result of a driver logic that wishes to terminate commands that the hardware may not be able to terminate. Such command completions are detected at the handler and proper return status is encoded. To be able to terminate page handler commands, we make sure to set the corresponding bit in the bitmask.

IB/mlx5: Remove support for IB_DEVICE_LOCAL_DMA_LKEY

2015-09-25T14:46:51Z

Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey is available") allows ULPs that make use of the local dma key to keep working as before by allocating a DMA MR with local permissions and converted these consumers to use the MR associated with the PD rather then device->local_dma_lkey. ConnectIB has some known issues with memory registration using the local_dma_lkey (SEND, RDMA, RECV seems to work ok). Thus don't expose support for it (remove device->local_dma_lkey setting), and take advantage of the above commit such that no regression is introduced to working systems. The local_dma_lkey support will be restored in CX4 depending on FW capability query. Signed-off-by: Sagi Grimberg Signed-off-by: Doug Ledford

Pull inifiniband/rdma updates from Doug Ledford: "This is a fairly sizeable set of changes. I've put them through a decent amount of testing prior to sending the pull request due to that. There are still a few fixups that I know are coming, but I wanted to go ahead and get the big, sizable chunk into your hands sooner rather than waiting for those last few fixups. Of note is the fact that this creates what is intended to be a temporary area in the drivers/staging tree specifically for some cleanups and additions that are coming for the RDMA stack. We deprecated two drivers (ipath and amso1100) and are waiting to hear back if we can deprecate another one (ehca). We also put Intel's new hfi1 driver into this area because it needs to be refactored and a transfer library created out of the factored out code, and then it and the qib driver and the soft-roce driver should all be modified to use that library. I expect drivers/staging/rdma to be around for three or four kernel releases and then to go away as all of the work is completed and final deletions of deprecated drivers are done. Summary of changes for 4.3: - Create drivers/staging/rdma - Move amso1100 driver to staging/rdma and schedule for deletion - Move ipath driver to staging/rdma and schedule for deletion - Add hfi1 driver to staging/rdma and set TODO for move to regular tree - Initial support for namespaces to be used on RDMA devices - Add RoCE GID table handling to the RDMA core caching code - Infrastructure to support handling of devices with differing read and write scatter gather capabilities - Various iSER updates - Kill off unsafe usage of global mr registrations - Update SRP driver - Misc mlx4 driver updates - Support for the mr_alloc verb - Support for a netlink interface between kernel and user space cache daemon to speed path record queries and route resolution - Ininitial support for safe hot removal of verbs devices" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (136 commits) IB/ipoib: Suppress warning for send only join failures IB/ipoib: Clean up send-only multicast joins IB/srp: Fix possible protection fault IB/core: Move SM class defines from ib_mad.h to ib_smi.h IB/core: Remove unnecessary defines from ib_mad.h IB/hfi1: Add PSM2 user space header to header_install IB/hfi1: Add CSRs for CONFIG_SDMA_VERBOSITY mlx5: Fix incorrect wc pkey_index assignment for GSI messages IB/mlx5: avoid destroying a NULL mr in reg_user_mr error flow IB/uverbs: reject invalid or unknown opcodes IB/cxgb4: Fix if statement in pick_local_ip6adddrs IB/sa: Fix rdma netlink message flags IB/ucma: HW Device hot-removal support IB/mlx4_ib: Disassociate support IB/uverbs: Enable device removal when there are active user space applications IB/uverbs: Explicitly pass ib_dev to uverbs commands IB/uverbs: Fix race between ib_uverbs_open and remove_one IB/uverbs: Fix reference counting usage of event files IB/core: Make ib_dealloc_pd return void IB/srp: Create an insecure all physical rkey only if needed ...

mlx5: Fix missing device local_dma_lkey

2015-08-29T02:54:46Z

The mlx5 driver exposes device capability IB_DEVICE_LOCAL_DMA_LKEY but does not set the the device local_dma_lkey. This breaks rpcrdma drivers. Query and set this lkey when creating the device resources. Signed-off-by: Sagi Grimberg Signed-off-by: Doug Ledford
