2022-11-30RDMA/hw/qib/qib_user_pages: remove FOLL_FORCE usageDavid Hildenbrand1-1/+1
FOLL_FORCE is really only for ptrace access. As we unpin the pinned pages using unpin_user_pages_dirty_lock(true), the assumption is that all these pages are writable. FOLL_FORCE in this case seems to be a legacy leftover. Let's just remove it.

2022-11-21RDMA/qib: don't pass bogus GFP_ flags to dma_alloc_coherentChristoph Hellwig2-18/+5
dma_alloc_coherent is an opaque allocator that only uses the GFP_ flags for allocation context control. Don't pass GFP_USER which doesn't make sense for a kernel DMA allocation or __GFP_COMP which makes no sense for an allocation that can't in any way be converted to a page pointer.

2021-06-16RDMA: Change ops->init_port to ops->port_groupsJason Gunthorpe3-25/+3
init_port was only being used to register sysfs attributes against the port kobject. Now that all users are creating static attribute_group's we can simply set the attribute_group list in the ops and the core code can just handle it directly. This makes all the sysfs management quite straightforward and prevents any driver from abusing the naked port kobject in future because no driver code can access it.

2021-03-26RDMA: Support more than 255 rdma portsMark Bloch6-15/+15
Current code uses many different types when dealing with a port of a RDMA device: u8, unsigned int and u32. Switch to u32 to clean up the logic. This allows us to make (at least) the core view consistent and use the same type. Unfortunately not all places can be converted. Many uverbs functions expect port to be u8 so keep those places in order not to break UAPIs. HW/Spec defined values must also not be changed. With the switch to u32 we now can support devices with more than 255 ports. U32_MAX is reserved to make control logic a bit easier to deal with. As a device with U32_MAX ports probably isn't going to happen any time soon this seems like a non issue. When a device with more than 255 ports is created uverbs will report the RDMA device as having 255 ports as this is the max currently supported. The verbs interface is not changed yet because the IBTA spec limits the port size in too many places to be u8 and all applications that relies in verbs won't be able to cope with this change. At this stage, we are extending the interfaces that are using vendor channel solely Once the limitation is lifted mlx5 in switchdev mode will be able to have thousands of SFs created by the device. As the only instance of an RDMA device that reports more than 255 ports will be a representor device and it exposes itself as a RAW Ethernet only device CM/MAD/IPoIB and other ULPs aren't effected by this change and their sysfs/interfaces that are exposes to userspace can remain unchanged.
