2006-06-30IB/uverbs: Set correct user handle for user SRQsRoland Dreier
Store away the user handle passed in from userspace when creating an SRQ, so that the kernel can return the correct handle when an SRQ asynchronous event occurs.

2006-06-23[PATCH] VFS: Permit filesystem to override root dentry on mountDavid Howells
Extend the get_sb() filesystem operation to take an extra argument that permits the VFS to pass in the target vfsmount that defines the mountpoint. The filesystem is then required to manually set the superblock and root dentry pointers. For most filesystems, this should be done with simple_set_mnt() which will set the superblock pointer and then set the root dentry to the superblock's s_root (as per the old default behaviour). The get_sb() op now returns an integer as there's now no need to return the superblock pointer. This patch permits a superblock to be implicitly shared amongst several mount points, such as can be done with NFS to avoid potential inode aliasing. In such a case, simple_set_mnt() would not be called, and instead the mnt_root and mnt_sb would be set directly. The patch also makes the following changes: (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount pointer argument and return an integer, so most filesystems have to change very little. (*) If one of the convenience function is not used, then get_sb() should normally call simple_set_mnt() to instantiate the vfsmount. This will always return 0, and so can be tail-called from get_sb(). (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the dcache upon superblock destruction rather than shrink_dcache_anon(). This is required because the superblock may now have multiple trees that aren't actually bound to s_root, but that still need to be cleaned up. The currently called functions assume that the whole tree is rooted at s_root, and that anonymous dentries are not the roots of trees which results in dentries being left unculled. However, with the way NFS superblock sharing are currently set to be implemented, these assumptions are violated: the root of the filesystem is simply a dummy dentry and inode (the real inode for '/' may well be inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries with child trees. [*] Anonymous until discovered from another tree. (*) The documentation has been adjusted, including the additional bit of changing ext2_* into foo_* in the documentation.

2006-06-22IB/uverbs: Remove unnecessary list_del()sRoland Dreier
In ib_uverbs_cleanup_ucontext(), when iterating through the lists of objects, there's no reason to do list_del() to remove the objects, since both the objects and the lists that contain them are about to be freed anyway. Since list_del() is a moderately big inline function, getting rid of this extra work saves quite a bit of .text: add/remove: 0/0 grow/shrink: 1/2 up/down: 3/-217 (-214) function old new delta ib_uverbs_comp_handler 225 228 +3 ib_uverbs_async_handler 256 255 -1 ib_uverbs_close 905 689 -216 Signed-off-by: Roland Dreier <rolandd@cisco.com>
2006-06-22IB/uverbs: Don't free wr list when it's known to be emptyKrishna Kumar
In ib_uverbs_post_send(), move the "out:" label after the loop that frees the list of work requests, since the only place that jumps there is before any work requests could possibly be added to the list.

2006-06-17IB/uverbs: Don't serialize with ib_uverbs_idr_mutexRoland Dreier
Currently, all userspace verbs operations that call into the kernel are serialized by ib_uverbs_idr_mutex. This can be a scalability issue for some workloads, especially for devices driven by the ipath driver, which needs to call into the kernel even for datapath operations. Fix this by adding reference counts to the userspace objects, and then converting ib_uverbs_idr_mutex into a spinlock that only protects the idrs long enough to take a reference on the object being looked up. Because remove operations may fail, we have to do a slightly funky two-step deletion, which is described in the comments at the top of uverbs_cmd.c. This also still leaves ib_uverbs_idr_lock as a single lock that is possibly subject to contention. However, the lock hold time will only be a single idr operation, so multiple threads should still be able to make progress, even if ib_uverbs_idr_lock is being ping-ponged. Surprisingly, these changes even shrink the object code: add/remove: 23/5 grow/shrink: 4/21 up/down: 633/-693 (-60) Signed-off-by: Roland Dreier <rolandd@cisco.com>

2006-04-10IB: simplify static rate encodingJack Morgenstein
Push translation of static rate to HCA format into low-level drivers, where it belongs. For static rate encoding, use encoding of rate field from IB standard PathRecord, with addition of value 0, for backwards compatibility with current usage. The changes are: - Add enum ib_rate to midlayer includes. - Get rid of static rate translation in IPoIB; just use static rate directly from Path and MulticastGroup records. - Update mthca driver to translate absolute static rate into the format used by hardware.

This patch uses linked list of memory buffers when sending and receiving data to avoid needing contiguous pages for larger transfers. Receive side: copy the arriving MADs in chunks instead of coalescing to one large buffer in kernel space. Send side: split a multipacket MAD buffer to a list of segments, (multipacket_list) and send these using a gather list of size 2. Also, save pointer to last sent segment, and retrieve requested segments by walking list starting at last sent segment. Finally, save pointer to last-acked segment.

2006-03-20IB/mad: Simplify SMI by eliminating smi_check_local_dr_smp()Ralph Campbell
The call to ib_get_agent_port() shouldn't be possible to fail when smi_check_local_dr_smp() is called from ib_mad_recv_done_handler(). When it is called from handle_outgoing_dr_smp(), the device and port_num come from mad_agent_priv so I assume the call to ib_get_agent_port() shouldn't fail either. In either case, smi_check_local_smp() only uses the mad_agent pointer to check that mad_agent->device->process_mad is not NULL. The device pointer would have to be the same as the one passed to smi_check_local_dr_smp() since that pointer is used later instead of the one checked in smi_check_local_smp().
