* IB/ipath: Add locking for interrupt use of ipath_pd contexts vs freeDave Olson2008-12-051-0/+2
| | | | | | | Fixes timing race resulting in panic. Not a performance sensitive path. Signed-off-by: Dave Olson <dave.olson@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/ipath: Fix up some debug messagesBryan O'Sullivan2007-04-181-1/+1
| | | | | | | ipath_dbg doesn't need the same prefixes that printk does. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Implement new verbs DMA mapping functionsRalph Campbell2006-12-121-4/+4
| | | | | | | | | This patch implements the interposing DMA mapping functions to allow support for IOMMUs and remove the dependence on phys_to_virt() and bus_to_virt(). Signed-off-by: Ralph Campbell <ralph.campbell@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
* IB/ipath: Ensure that PD of MR matches PD of QP checking the RkeyBryan O'Sullivan2006-09-281-4/+8

* IB/ipath: Fix ib_ipath driver to work with SRPRalph Campbell2006-07-241-0/+15
| | | | | | | | | | | I am still working on a proposal to remove the phys_to_virt() calls in the ib_ipath driver. In the mean time, this patch allows SRP to work by fixing the R_Key check and conversion from IB address to kernel virtual address. It also returns the correct page size for FMRs.

* [PATCH] IB/ipath: rC receive interrupt performance changesBryan O'Sullivan2006-07-011-22/+28
| | | | | | | | | | | | | | This patch separates QP state used for sending and receiving RC packets so the processing in the receive interrupt handler can be done mostly without locks being held. ACK packets are now sent without requiring synchronization with the send tasklet.

* IB/ipath: fix spinlock recursion bugBryan O'Sullivan2006-05-231-6/+0
| | | | | | | | | The local loopback path for RC can lock the rkey table lock without blocking interrupts. The receive interrupt path can then call ipath_rkey_ok() and deadlock. Remove the redundant lock. Signed-off-by: Bryan O'Sullivan <bos@pathscale.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
