STRUCT STM32_TIMERS_DMA(9)

💖 struct stm32_timers_dma — NAME 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this page is literally all about struct stm32_timers_dma, which is the STM32 timer DMA handling situation. that's it, that's the vibe 🎀

🌸 SYNOPSIS 🌸

no cap, here's the whole struct, verbatim, don't @ me:

struct stm32_timers_dma {
    struct completion completion;
    phys_addr_t phys_base;
    struct mutex lock;
    struct dma_chan *chan;
    struct dma_chan *chans[STM32_TIMERS_MAX_DMAS];
 };

🦋 Members 🦋

breaking it down field by field, iykyk 👑

• completion — this is a struct completion, and it's giving "end of DMA transfer completion" energy. when the DMA transfer wraps up, this is the thing that says so 🫶
• phys_base — a phys_addr_t holding the control registers physical base address. literally where the registers live in physical memory, iconic 💅
• lock — a struct mutex whose whole job is to protect DMA access. main character energy but make it thread-safe 🔥
• chan — a struct dma_chan * pointing at the DMA channel actually in use rn 👀
• chans — a struct dma_chan * array, chans[STM32_TIMERS_MAX_DMAS], holding all the DMA channels available for this timer instance. a little squad of channels, obsessed 🌈
