2006-09-28IB/ipath: Driver support for userspace sharing of HW contextsBryan O'Sullivan
This allows multiple userspace processes to share a single hardware context in a master/slave arrangement. It is backwards binary compatible with existing userspace. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: fix return value from ipath_pollBryan O'Sullivan
This stops the generic poll code from waiting for a timeout. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: support new QLogic product naming schemeBryan O'Sullivan
This patch only renames files, fixes product names, and updates comments. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: remove stale references to userspace SMABryan O'Sullivan
When we first submitted a userspace subnet management agent, it was rejected, so we left it out of the final driver submission. This patch removes a number of vestigial references to it. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: simplify layering codeBryan O'Sullivan
A lot of ipath layer code was only called in one place. Now that the ipath_core and ib_ipath drivers are merged, it's more sensible to simply inline the simple stuff that the layer code was doing.

2006-09-22IB/ipath: drop requirement that PIO buffers be mmaped write-onlyBryan O'Sullivan
Some userlands try to mmap these pages read-write, so accommodate them. Signed-off-by: Bryan O'Sullivan <bryan.osullivan@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-09-22IB/ipath: More changes to support InfiniPath on PowerPC 970 systemsBryan O'Sullivan
Ordering of writethrough store buffers needs to be forced, and we need to use ifdef to get writethrough behavior to InfiniPath buffers, because there is no generic way to specify that at this time (similar to code in char/drm/drm_vm.c and block/z2ram.c).

2006-07-01[PATCH] IB/ipath: namespace cleanup: replace ips with ipathBryan O'Sullivan
Remove ips namespace from infinipath drivers. This renames ips_common.h to ipath_common.h. Definitions, data structures, etc. that were not used by kernel modules have moved to user-only headers. All names including ips have been renamed to ipath. Some names have had an ipath prefix added.

2006-07-01[PATCH] IB/ipath: fix a bug that results in addresses near 0 being written ↵Bryan O'Sullivan
via DMA We can't tell for sure if any packets are in the infinipath receive buffer when we shut down a chip port. Normally this is taken care of by orderly shutdown, but when processes are terminated, or sending process has a bug, we can continue to receive packets. So rather than writing zero to the address registers for the closing port, we point it at a dummy memory.

2006-07-01[PATCH] IB/ipath: memory management cleanupsBryan O'Sullivan
Made in-memory rcvhdrq tail update be in dma_alloc'ed memory, not random user or special kernel (needed for ppc, also "just the right thing to do"). Some cleanups to make unexpected link transitions less likely to produce complaints about packet errors, and also to not leave SMA packets stuck and unable to go out. A few other random debug and comment cleanups. Always init rcvhdrq head/tail registers to 0, to avoid race conditions (should have been that way some time ago).

2006-07-01[PATCH] IB/ipath: allow diags on any unitBryan O'Sullivan
There is no longer a /dev/ipath_diag file; instead, there's /dev/ipath_diag0, 1, etc. It's still not possible to have diags run on more than one unit at a time, but that's easy to fix at some point.

2006-05-23IB/ipath: enable PE800 receive interrupts on user portsBryan O'Sullivan
Fixed so it works on the PE-800. It had not previously been updated to match PE-800 receive interrupt differences from HT-400. Signed-off-by: Bryan O'Sullivan <bos@pathscale.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-03-31IB/ipath: support for userspace apps using core driverBryan O'Sullivan
These files introduce a char device that userspace apps use to gain direct memory-mapped access to the InfiniPath hardware, and routines for pinning and unpinning user memory in cases where the hardware needs to DMA into the user address space.
