irdma_query_qp(9)
β¨ irdma_query_qp β query qp attributes β¨
okay so bestie, welcome to irdma_query_qp(9) from the Kernel API Manual π
this one lives in the infiniband/irdma corner of the kernel and it's literally just: you hand it a QP, it hands you back the attributes. lowkey iconic, highkey simple. no cap π«Ά
πΈ SYNOPSIS πΈ
int irdma_query_qp (struct ib_qp *ibqp , struct ib_qp_attr *attr , int
attr_mask , struct ib_qp_init_attr *init_attr );
that's the whole signature, copy it exactly, don't get creative with it π it returns an int, periodt.
π ARGUMENTS π
ibqpβ the qp pointer. like, the queue pair you're asking about. that's your main character π―attrβ attributes pointer. this is where the attribute-y stuff goes. β¨attr_maskβ Not used. fr fr, it's not used. don't come for me, that's just what the page says πinit_attrβ qp attributes to return. this is the goodie bag you get back at the end π
π¦ SEE ALSO π¦
so the kernel file for this one is ./drivers/infiniband/hw/irdma/verbs.c β that's where the magic lives π and here's the whole friend group, every single one, no skips, no cuts π:

like, the whole roster. bestie really said "you're gonna meet everyone" ππ
ngl that_irdma_destroy_qp(9)with the leading underscore is NOT a typo β it's a different function fromirdma_destroy_qp(9). keep both, they're both invited. π«Ά
and that's the page, mwah π this little beauty ships from the path ./drivers/infiniband/hw/irdma, dated October 2026, and it goes by irdma_query_qp(9) β that's the source, the version and the date all in one, so you can cite it and slay responsibly πβ¨πΈ
