[IB] uverbs: have kernel return QP capabilities

2005-11-10T18:22:50Z

Move the computation of QP capabilities (max scatter/gather entries, max inline data, etc) into the kernel, and have the uverbs module return the values as part of the create QP response. This keeps precise knowledge of device limits in the low-level kernel driver. This requires an ABI bump, so while we're making changes, get rid of the max_sge parameter for the modify SRQ command -- it's not used and shouldn't be there.

[IB] Have cq_resize() method take an int, not int*

2005-11-10T18:22:50Z

Change the struct ib_device.resize_cq() method to take a plain integer that holds the new CQ size, rather than a pointer to an integer that it uses to return the new size. This makes the interface match the exported ib_resize_cq() signature, and allows the low-level driver to update the CQ size with proper locking if necessary. No in-tree drivers are exporting this method yet. Signed-off-by: Roland Dreier

[IB] ucm: 32/64 compatibility fixes

2005-11-01T21:18:54Z

Fix structure layouts to ensure same size on 32-bit and 64-bit architectures. This permits 32-bit userspace apps on a 64-bit kernel. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

[IB] Fix MAD layer DMA mappings to avoid touching data buffer once mapped

2005-10-25T17:51:39Z

The MAD layer was violating the DMA API by touching data buffers used for sends after the DMA mapping was done. This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

[IB] CM: bind IDs to a specific device

2005-10-17T22:37:43Z

Bind communication identifiers to a device to support device removal. Export per HCA CM devices to userspace. Signed-off-by: Sean Hefty

[IB] uverbs: Add ABI structures for more commands

2005-10-17T22:20:30Z

Add kernel/user ABI structures for marshalling poll CQ, request CQ notification, post send, post receive, post SRQ receive, create AH and destroy AH commands. These commands allow us to support userspace verbs for devices that can't perform these operations directly from userspace (eg the PathScale HCA). Signed-off-by: Roland Dreier

[IB] uverbs: Add a mask of device methods allowed for userspace

2005-10-17T22:20:30Z

Give each device a uverbs_cmd_mask, so that a low-level driver can control which methods may be called on behalf of userspace. Signed-off-by: Roland Dreier

[IB] uverbs: Add device-specific ABI version attribute

2005-10-17T22:20:26Z

Add abi_version attribute to uverbs class devices to allow for ABI versioning of device-specific interfaces. Signed-off-by: Roland Dreier

[IB] uverbs: ABI-breaking fixes for userspace verbs

2005-10-17T22:20:25Z

Introduce new userspace verbs ABI version 3. This eliminates some unneeded commands, and adds support for user-created completion channels. This cleans up problems with file leaks on error paths, and also makes sure that file descriptors are always installed into the correct process. Signed-off-by: Roland Dreier

[PATCH] gfp flags annotations - part 1

2005-10-08T22:00:57Z

- added typedef unsigned int __nocast gfp_t; - replaced __nocast uses for gfp flags with gfp_t - it gives exactly the same warnings as far as sparse is concerned, doesn't change generated code (from gcc point of view we replaced unsigned int with typedef) and documents what's going on far better.
