saa711x_detect_chip(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… NAME πŸ’…

okay bestie, welcome to saa711x_detect_chip(9), a page from the Kernel API Manual. Its whole thing? saa711x_detect_chip β€” detects the saa711x (or clone) variant. literally its entire job. it's giving chip detective energy. πŸ’–

✨ SYNOPSIS ✨

int saa711x_detect_chip (struct i2c_client *client , const struct
       i2c_device_id *id , char *name );

πŸŽ€ ARGUMENTS πŸŽ€

  • client β€” the I2C client structure. your main character struct, basically.
  • id β€” the I2C device ID structure. the little ID card.
  • name β€” the name of the device to be filled. yes, it gets filled in; we do not fill it in ourselves, the function handles that.

πŸ¦‹ DESCRIPTION πŸ¦‹

so okay: this function detects the Philips/NXP saa711x chip, or some clone of it. iconic behavior, no cap.

if id is NULL or id->driver_data is equal to 1, it auto-probes the analog demod. simple as that.

if the tuner is not found, it returns -ENODEV. not found = not found, bestie.

if auto-detection is disabled and the tuner doesn't match what it was required, it returns -EINVAL and fills name. so yes, name is getting content in that case too.

if the chip is found, it returns the chip ID and fills name. slay.
