t4_cim_read(9)

💖 t4_cim_read(9) — your Kernel API Manual bestie 💖

okay so welcome to the t4_cim_read(9) page from the Kernel API Manual, bestie 🫶. This one is short and sweet: it’s the “read a block from CIM internal address space” girlie 💅.

✨ NAME ✨

t4_cim_read — read a block from CIM internal address space

🌸 SYNOPSIS 🌸

int t4_cim_read (struct adapter *adap , unsigned int addr , unsigned int
       n , unsigned int *valp );

🎀 ARGUMENTS 🎀

• adap — the adapter.
• addr — the start address within the CIM address space.
• n — number of words to read.
• valp — where to store the result.

🦋 DESCRIPTION 🦋

Reads a block of 4-byte words from the CIM intenal address space. That’s it — that’s the whole vibe: a little block read, no drama 🔥. And yes, “intenal” is literally how the page spells it, so we’re not fixing the typo, we’re respecting the lore 😭.

🔥 SEE ALSO 🔥

• Kernel file ./drivers/net/ethernet/chelsio/cxgb4/t4_hw.c.
