sw_r_table(9) πŸ’…

okay bestie, this page comes from the Kernel API Manual, and it’s giving β€œtiny switch-table read with main character energy” βœ¨πŸ’–. no cap, it’s a whole little routine.


✨ NAME ✨

sw_r_table β€” read 4 bytes of data from switch table πŸ’Ύβœ¨


🌸 SYNOPSIS 🌸

void sw_r_table (struct ksz_hw *hw , int table , u16 addr , u32 *data );

πŸŽ€ ARGUMENTS πŸŽ€

  • hw β€” the hardware instance, periodt 🫢
  • table β€” the table selector; pick your table, bestie 🎯
  • addr β€” the address of the table entry πŸ“
  • data β€” buffer to store the read data πŸ’Œ

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so this routine reads 4 bytes of data from the table of the switch. that’s literally the mission: 4 bytes, switch table, done πŸ˜­πŸ’–.

while it’s doing that, hardware interrupts are disabled to minimize corruption of read data. so yeah β€” interrupts get blocked so the read data doesn’t get messy. protective bubble moment 🫧✨.
