Hello Mike Marciniszyn,
The patch 36a8f01cd24b: "IB/qib: Add congestion control agent
implementation" from Jul 19, 2012, leads to the following warning:
drivers/infiniband/hw/qib/qib_init.c:230 qib_init_pportdata()
warn: value 1984 can't fit into 255 'ppd->cc_supported_table_entries'
drivers/infiniband/hw/qib/qib_init.c
227 if (qib_cc_table_size < IB_CCT_MIN_ENTRIES)
228 goto bail;
229
230 ppd->cc_supported_table_entries = min(max_t(int,
qib_cc_table_size,
231 IB_CCT_MIN_ENTRIES),
IB_CCT_ENTRIES*IB_CC_TABLE_CAP_DEFAULT);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
64 * 31 = 1984
->cc_supported_table_entries is a u8 so 1984 gets truncated.
232
233 ppd->cc_max_table_entries =
234 ppd->cc_supported_table_entries/IB_CCT_ENTRIES;
235
regards,
dan carpenter
