irdma_get_dma_mr(9)
π irdma_get_dma_mr(9) β from the Kernel API Manual, bestie
okay so real talk, this one's a little function from the irdma crew and it's literally just here to register physical mem β¨ that's it, that's the whole vibe. short page, iconic behaviour, no notes.
β¨ NAME β¨
irdma_get_dma_mr β register physical mem π«Ά
π SYNOPSIS π
struct ib_mr * irdma_get_dma_mr (struct ib_pd *pd , int acc );
it gives you back a struct ib_mr *, and yeah the spacing in there is exactly how it shipped, we don't touch the source β¨
πΈ ARGUMENTS πΈ
pdβ ptr of pd π literally the pointer to the pd, that's the whole storyaccβ access for memory π₯ the access bits you're handing over for that memory

ngl there's no exit status, no error list, no env vars on this page β it's a short queen and we respect her. don't go inventing behaviour that isn't written down, that's not the move π
and that's the page, bestie! π§ this little beauty comes out of ./drivers/infiniband/hw/irdma, dated October 2026, and lives under the title irdma_get_dma_mr(9). slay, go register some physical mem ππ
