π stmmac_init_rx_buffers(9) π
okay so bestie, welcome to the Kernel API Manual β¨ this one's a little kernel function from the stmmac driver family and honestly? she's the moment. no cap.
πΈ NAME πΈ
stmmac_init_rx_buffers β init the RX descriptor buffer. that's it, that's the whole vibe π
β¨ SYNOPSIS β¨
int stmmac_init_rx_buffers (struct stmmac_priv *priv , struct
stmmac_dma_conf *dma_conf , struct dma_desc *p , int i , gfp_t flags ,
u32 queue );
like, just copy it exactly, don't @ me π
π¦ ARGUMENTS π¦
privβ the driver private structure. her private business, respectfully πdma_confβ the structure that takes the dma data. she's holding the DMA lore π«Άpβ descriptor pointer. literally pointing at the descriptor, main character energy β¨iβ descriptor index. which one, bestie? this one π’flagsβ gfp flag. the flag of the gfp variety, periodt πqueueβ RX queue index. which RX queue we're living in rn π
π DESCRIPTION π
so this function gets called to allocate a receive buffer, perform the DMA mapping, and init the descriptor. all three, in one go, no skips. it's giving multitasking icon πβ¨
