okay so bestie, welcome to the Kernel API Manual entry for zynq_qspi_write_op, and no cap this one is a little workhorse β it's the function that fills the TX FIFO with as many bytes as possible. that's the whole vibe. it's giving "shove data in until there's no room left" and honestly? iconic. π
β¨ NAME β¨
zynq_qspi_write_op β fills the TX FIFO with as many bytes as possible π¦
β¨ SYNOPSIS β¨
void zynq_qspi_write_op (struct zynq_qspi *xqspi , int txcount , bool
txempty );
like, look at her. void return, three arguments, zero drama. she takes xqspi, txcount, and txempty and she gets to work. periodt. π
β¨ ARGUMENTS β¨
xqspiβ pointer to thezynq_qspistructure π literally the main character of this whole file, she's the state everything hangs off of.txcountβ the maximum number of words to write π₯ think of it as the ceiling, the limit, the "bestie we are NOT going over this" number.txemptyβ indicates that the TxFIFO is empty πΈ a lilboolflag telling you the FIFO has nothing in it right now. lowkey important context, ngl.
