Remove the volatile qualifier from the cq_vbase member of struct nes_hw_cq, and add an rmb() in the one place where it looks like access order might make a difference. As usual, removing a volatile qualifier in a declaration is actually a bug fix, since a volatile qualifier is not sufficient to make sure that aggressively out-of-order CPUs don't reorder things and cause incorrect results. For example, a CPU might speculatively execute reads of other cqe fields before the NIC hardware has written those fields and before it has set the NES_CQE_VALID bit (even though those reads come after the test of the NES_CQE_VALID bit in program order), but then when the CPU actually executes the conditional test of the NES_CQE_VALID, the bit has been set, and the CPU will proceed with the results of the earlier speculative execution and end up using bogus data. This also gets rid of the warning: drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_destroy_cq': drivers/infiniband/hw/nes/nes_verbs.c:1978: warning: passing argument 3 of 'pci_free_consistent' discards qualifiers from pointer target type Signed-off-by: NRoland Dreier <rolandd@cisco.com>

由 Chien Tung 提交于
After PXE boot, the iw_nes driver does a full reset to ensure the card is in a clean state. However, it doesn't wait for firmware to complete its work before issuing a port reset to enable the ports, which leads to problems bringing up the ports. The solution is to wait for firmware to complete its work before proceeding with port reset. This bug was flagged by Roland Dreier <rolandd@cisco.com>.

Before IBA7220 support was added, the ipath driver didn't support any hardware unless PCI_MSI and/or HT_IRQ was enabled. However, the IBA7220 can generate INTx interrupts, so it makes sense to allow the driver to be build even if PCI_MSI=n and HT_IRQ=n. Signed-off-by: NRoland Dreier <rolandd@cisco.com>

由 Roland Dreier 提交于
The new IBA7220 code added a call to ipath_init_iba7220_funcs() that is compiled unconditionally, but only built the IBA7220 code if PCI_MSI is enabled. Fix this by building the IBA7220 file unconditonally. This fixes build breakage when PCI_MSI=n, HT_IRQ=y and INFINIBAND_IPATH=y reported by Ingo Molnar <mingo@elte.hu>: drivers/built-in.o: In function `ipath_init_one': ipath_driver.c:(.devinit.text+0x1e5bc): undefined reference to `ipath_init_iba7220_funcs' Signed-off-by: NRoland Dreier <rolandd@cisco.com>

IB/ipath: Remove reference to dev->class_dev Commit 124b4dcb ("IB/ipath: add calls to new 7220 code and enable in build") inadvertently added core to set dev->class_dev.dev back into ib_ipath. This is completely redundant since commit 1912ffbb ("IB: Set class_dev->dev in core for nice device symlink"), which removed class_dev setting from low-level drivers, and also will break the build when class_dev is removed completely from struct ib_device.

Handle IB_WR_SEND_WITH_INV work requests. This resurrects a patch sent long ago by Mikkel Hagen <mhagen@iol.unh.edu>. Signed-off-by: NRoland Dreier <rolandd@cisco.com>
-
由 Roland Dreier 提交于
Add a new IB_WR_SEND_WITH_INV send opcode that can be used to mark a "send with invalidate" work request as defined in the iWARP verbs and the InfiniBand base memory management extensions. Also put "imm_data" and a new "invalidate_rkey" member in a new "ex" union in struct ib_send_wr. The invalidate_rkey member can be used to pass in an R_Key/STag to be invalidated. Add this new union to struct ib_uverbs_send_wr. Add code to copy the invalidate_rkey field in ib_uverbs_post_send(). Fix up low-level drivers to deal with the change to struct ib_send_wr, and just remove the imm_data initialization from net/sunrpc/xprtrdma/, since that code never does any send with immediate operations. Also, move the existing IB_DEVICE_SEND_W_INV flag to a new bit, since the iWARP drivers currently in the tree set the bit. The amso1100 driver at least will silently fail to honor the IB_SEND_INVALIDATE bit if passed in as part of userspace send requests (since it does not implement kernel bypass work request queueing). Remove the flag from all existing drivers that set it until we know which ones are OK. The values chosen for the new flag is not consecutive to avoid clashing with flags defined in the XRC patches, which are not merged yet but which are already in use and are likely to be merged soon.
