qed_dmae_host2grc(9)

okay bestie, welcome to the qed_dmae_host2grc(9) page from the Kernel API Manual — yes, the manual name is getting folded in right here because we're cute like that ✨💅

✨ NAME ✨

qed_dmae_host2grc — copies data from source addr to dmae registers using the given ptt. no cap, that's the whole vibe 🫶

🎀 SYNOPSIS 🎀

the signature is exactly this, character for character, bestie:

int qed_dmae_host2grc (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
       u64 source_addr , u32 grc_addr , u32 size_in_dwords , struct
       qed_dmae_params *p_params );

💖 ARGUMENTS 💖

these are the little cuties you pass in:

• p_hwfn — HW device data.
• p_ptt — P_ptt. (yes bestie, that's literally the whole description 🫶)
• source_addr — Source address.
• grc_addr — GRC address (dmae_data_offset).
• size_in_dwords — Size.
• p_params — default parameters will be used in case of NULL ✨ (that parenthetical is doing main character work).

🦋 RETURN 🦋

Int. — that's the return. short king behavior, honestly 💅
