Hey Roland,
I just found a bug in a drop I did for libcxgb3. I changed the code to
read the adapter fw version sysfs file to attempt to check for
incompatible fw/lib cases. I was reading this file in cxgb3_driver_init():
/sys/class/infiniband_verbs/uverbs0/device/infiniband:cxgb3_0/fw_ver
I'm using ibv_read_sysfs_file() and the uverbs_sys_path passed in, but
building the string to dive down into the device/infiniband:blah directory.
However this infiniband:cxgb3_0 link apparently is not present on a
rhel4u5 distro. I assumed this stuff would always be consistent for
ofed installations.
Is that not true?
What is the preferred way for a lib to get to the device's sysfs files?
Thanks!
Steve.
