2019-08-20xprtrdma: Boost client's max slot table size to match Linux serverChuck Lever1-2/+2
I've heard rumors of an NFS/RDMA server implementation that has a default credit limit of 1024. The client's default setting remains at 128. Signed-off-by: Chuck Lever <[email protected]> Signed-off-by: Anna Schumaker <[email protected]>

2018-01-16xprtrdma: Replace all usage of "frmr" with "frwr"Chuck Lever1-1/+1
Clean up: Over time, the industry has adopted the term "frwr" instead of "frmr". The term "frwr" is now more widely recognized. For the past couple of years I've attempted to add new code using "frwr" , but there still remains plenty of older code that still uses "frmr". Replace all usage of "frmr" to avoid confusion. While we're churning code, rename variables unhelpfully called "f" to "frwr", to improve code clarity. Signed-off-by: Chuck Lever <[email protected]> Signed-off-by: Anna Schumaker <[email protected]>
2016-09-19xprtrdma: Support larger inline thresholdsChuck Lever1-2/+2
The Version One default inline threshold is still 1KB. But allow testing with thresholds up to 64KB. This maximum is somewhat arbitrary. There's no fundamental architectural limit I'm aware of, but it's good to keep the size of Receive buffers reasonable. Now that Send can use a s/g list, a Send buffer is only as large as each RPC requires. Receive buffers are always the size of the inline threshold, however.

2016-05-17xprtrdma: Bound the inline threshold valuesChuck Lever1-1/+3
Currently the sysctls that allow setting the inline threshold allow any value to be set. Small values only make the transport run slower. The default 1KB setting is as low as is reasonable. And the logic that decides how to divide a Send buffer between RPC-over-RDMA header and RPC message assumes (but does not check) that the lower bound is not crazy (say, 57 bytes). Send and receive buffers share a page with some control information. Values larger than about 3KB can't be supported, currently.

2015-08-05xprtrdma: Increase default credit limitChuck Lever1-1/+1
In preparation for similar increases on NFS/RDMA servers, bump the advertised credit limit for RPC/RDMA to 128. This allocates some extra resources, but the client will continue to allow only the number of RPCs in flight that the server requests via its advertised credit limit.

2014-07-31xprtrdma: Remove RPCRDMA_PERSISTENT_REGISTRATION macroChuck Lever1-2/+0
Clean up. RPCRDMA_PERSISTENT_REGISTRATION was a compile-time switch between RPCRDMA_REGISTER mode and RPCRDMA_ALLPHYSICAL mode. Since RPCRDMA_REGISTER has been removed, there's no need for the extra conditional compilation.
