πŸ’… tegra_qspi_handle_timeout(9) β€” Kernel API Manual πŸŽ€

okay so bestie, welcome to the Kernel API Manual, and today's main character is tegra_qspi_handle_timeout ✨ literally the little function that saves your transfer from getting flunked for something that wasn't even its fault. iykyk.


🌸 NAME 🌸

tegra_qspi_handle_timeout β€” handle a transfer timeout, but with a hardware check first πŸ•΅οΈβ€β™€οΈπŸ’–


✨ SYNOPSIS ✨

int tegra_qspi_handle_timeout (struct tegra_qspi *tqspi );

no cap, that's the whole signature. copy it exactly, spaces and all 🫢


πŸŽ€ ARGUMENTS πŸŽ€

  • tqspi β€” the QSPI controller instance πŸ’« like, the actual controller object you're dealing with.

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so picture this: a timeout happens 😭 but the hardware has already finished the transfer β€” the interrupt just got lost or delayed, which is so rude of it honestly. when that happens, this function steps in and manually triggers the transfer completion processing πŸ”₯

the whole point? it avoids failing transfers that actually succeeded. like, not me letting a perfectly good transfer flop just because the interrupt was late πŸ’€ slay behavior, honestly.


🌈 RETURN 🌈

  • 0 β€” transfer was completed βœ… iconic, we love a happy ending
  • -ETIMEDOUT β€” a real timeout πŸ˜” the genuine article, no hardware excuse
