STRUCT GPIO_V2_LINE_CONFIG_ATTRIBUTE(9)

💅 NAME 💅

okay so bestie, this is struct gpio_v2_line_config_attribute — literally a configuration attribute that's tied to one or more of the lines you requested ✨

🎀 SYNOPSIS 🎀

struct gpio_v2_line_config_attribute {
    struct gpio_v2_line_attribute attr;
    __aligned_u64 mask;
 };

no cap, that's the whole glow-up 💖

🌸 Members 🌸

• attr — the configurable attribute itself, the main character of this struct 👑 it's the actual thing you're configuring.
• mask — a bitmap that says which lines this attribute applies to 🫶 each bit number corresponds to the index into struct gpio_v2_line_request.offsets. so like, bit 0 = the line at offsets[0], bit 1 = offsets[1], iykyk 💅
