Hi Vlad,
during testing of RDS, a number of issues came up that I had to
address. Some of them were bugs, others were usability issues.
I submitted the following patches to
git://git.openfabrics.org/~okir/ofed_1_3/linux-2.6.git code-drop-20080617
d9fd0d04ba31951bcd7fe4393bccfe98ab8a45d5 RDS: introduce rds_send_get_message
9906c6480cedb05905d23c696671bcde9894b6ed RDS: Track whether RDMA S/G list is
DMA mapped
db7a8ed76ac77e6a5352c8d41d28d9fac59e953d RDS: Another fix for RDMA signalling
These fix another issue with signaling the completion of RDMA
operations.
2665a94825a234fdd989ed98ae24c88bd3415368 RDS: Use vmalloc in rds_ib_setup_qp
On a loaded system, re-establishing a broken RDS connection would
fail because we tried to kmalloc the send and receive ring, which
would result in an order-5 allocation.
1c3446c39af17e77fe7d39f32388e4c6462ee550 RDS: increase size of stats counters
The stats counters interface to user space uses uint64_t, but inside the
kernel, only "unsigned long" was used. On 32bit boxes this caused
counters
to be truncated.
1955124f7def27d55e98bfaff0c8da1438f2cca6 RDS: Expose info on IB connections
c2d8ba51f925cddca73562611ead156e62c3f93a RDS: Extend IB connection info to
include settings
People asked for a way to identify the IB port a RDS connection would
use
when the application does the load balancing.
804de7023165fd3fe89af6aac94843f195a23e72 RDS: Wake up send worker after TX
queue full condition is cleared
When encountering a full IB send queue, we back off for 2 jiffies. When
the send CQ handler frees up several entries, we want to kick the
send worker quickly. The existing code had a bug in it.
23d9822407b96538950e9e3dff5a7dfdbb464efb RDS: Send notification for cancelled
RDMA ops
We need notifications for RDMA operations that got canceled using
RDS_CANCEL_SENT_TO
5e210431f65089062302c6e5ae9e998d67b9a980 RDS: Add mr_pool_depleted stats counter
Track how often we were unable to initiate a RDMA because we couldn't
allocate a FMR from our pool.
b99faff27c2c4e4b1058580645d997ce82d87ec0 RDS: rds-info -k should display inode
number
In order to identify the process holding a specific RDS socket, we want
rds-info -k to show the socket's inode number, so that we can search
/proc/*/fd for it
eabede450f3d540605882727a3b71a116919d5c1 RDS: Clarify comment on rds_poll
Cosmetic - Rick complained about a misleading comment in rds_poll :)
------------------------
The rds-info changes go with several patches to rds-tools, which I also pushed
to
my tree:
git://git.openfabrics.org/~okir/ofed_1_3/rds-tools.git code-drop-20080617
e40149599d03c057b99df78608794dbb8803d732 rds-info: introduce address printing
functions
4f84065a0b3aae50c2ee346d4b8935b654f9f64c rds-info: add option to display IB
connections
This implements display of RDS/IB connections
15eb9f7dfe6724857c80a698cf339146088c1bc8 rds-info: Add -v option
4b90f7329dc146f01ca5b91eda924bcf0f8aef3f rds-info: Extend IB connection info to
include settings
This displays per-connection IB settings such as max_send_wr if -v is
given
794d3504649e5686342232cdad59b1cc6b445b35 rds-info -k should display inode number
Display the inode number of the RDS socket.
Can you please pull these into OFED-1.3?
Olaf
