qcom_pdc_gic_set_type(9)

💅 qcom_pdc_gic_set_type(9) — like, the Kernel API Manual page bestie 💅

okay so this is a page straight outta the Kernel API Manual, and it's literally about telling the PDC how to handle your interrupt. no cap, it's a whole mood. 🎀

✨ NAME ✨

qcom_pdc_gic_set_type — configure the PDC for the interrupt 🦋

✨ SYNOPSIS ✨

int qcom_pdc_gic_set_type (struct irq_data *d , unsigned int type );

✨ ARGUMENTS ✨

• d — the interrupt data. iconic. it's the irq_data, the whole main character of the call. 👑
• type — the interrupt type. yeah. that's the vibe check we're doing. 💅

✨ DESCRIPTION ✨

okay so here's the tea 🍓: if type is edge triggered, this function forwards that as a rising edge, because the PDC takes care of converting all edge types to a rising edge signal. literally all of them. not me being obsessed with the PDC's commitment to the rising edge aesthetic 💀✨

and if type is level, then it forwards that as level high, because — you guessed it — the PDC takes care of converting all level types to a level high signal. it's giving "the PDC handles the conversion, you just tell it edge or level." periodt. 🌸

so fr fr: edge in → rising edge out, level in → level high out. that's the whole conversion arc and the PDC is the one slaying it, not you. 🫶
