STRUCT ACP63_DEV_DATA(9)

💖 struct acp63_dev_data(9) 💖

okay bestie, welcome to the kernel API manual page for struct acp63_dev_data — that's the acp pci driver context, and it is so much more than a struct, it's literally the whole vibe of the ACP PCI driver wrapped up in one little bundle 🎀 (also hi, you're reading the struct acp63_dev_data(9) page, manual section 9, slay).

✨ NAME ✨

struct acp63_dev_data — acp pci driver context 🫶

🌸 SYNOPSIS 🌸

here's the whole thing, no cap, every single line:

struct acp63_dev_data {
    void __iomem *acp63_base;
    struct resource *res;
    struct acp_hw_ops *hw_ops;
    struct platform_device *pdm_dev;
    struct platform_device *dmic_codec_dev;
    struct platform_device *sdw_dma_dev;
    struct platform_device *mach_dev;
    struct mutex acp_lock;
    struct sdw_amd_acpi_info info;
    struct sdw_amd_ctx *sdw;
    struct snd_soc_acpi_mach *machines;
    bool is_sdw_dev;
    bool is_pdm_dev;
    bool is_pdm_config;
    bool is_sdw_config;
    bool sdw_en_stat;
    bool acp70_sdw0_wake_event;
    bool acp70_sdw1_wake_event;
    u32 addr;
    u32 reg_range;
    u32 acp_rev;
    u32 subsystem_vendor;
    u32 subsystem_device;
    u32 acp_sw_pad_keeper_en;
    u32 acp_pad_pulldown_ctrl;
    u16 acp63_sdw0_dma_intr_stat[ACP63_SDW0_DMA_MAX_STREAMS];
    u16 acp63_sdw1_dma_intr_stat[ACP63_SDW1_DMA_MAX_STREAMS];
    u16 acp70_sdw0_dma_intr_stat[ACP70_SDW0_DMA_MAX_STREAMS];
    u16 acp70_sdw1_dma_intr_stat[ACP70_SDW1_DMA_MAX_STREAMS];
 };

look at her. main character energy honestly 👑

🧚 Members 🧚

ngl, the page only spells out some of these for you — so here's every member it actually describes, in order, no skipping 💅

• acp63_base — the acp mmio base 🗺️
• res — resource
• hw_ops — ACP pci driver platform-specific ops ⚙️
• pdm_dev — ACP PDM controller platform device
• mach_dev — platform device for machine driver to support ACP PDM/SoundWire configuration 🎛️
• acp_lock — used to protect acp common registers 🔒 (yes queen, mutual exclusion)
• info — SoundWire AMD information found in ACPI tables 📋
• sdw — SoundWire context for all SoundWire manager instances 🌈
• is_sdw_dev — flag set to true when any SoundWire manager instances are available
• is_pdm_dev — flag set to true when ACP PDM controller exists
• is_pdm_config — flag set to true when PDM configuration is selected from BIOS
• is_sdw_config — flag set to true when SDW configuration is selected from BIOS
• sdw_en_stat — flag set to true when any one of the SoundWire manager instance is enabled ✅
• acp70_sdw0_wake_event — flag set to true when wake irq asserted for SW0 instance ⏰
• acp70_sdw1_wake_event — flag set to true when wake irq asserted for SW1 instance ⏰
• addr — pci ioremap address 📍
• reg_range — ACP register range
• acp_rev — ACP PCI revision id 🏷️
• acp_sw_pad_keeper_en — store acp SoundWire pad keeper enable register value 🛟
• acp_pad_pulldown_ctrl — store acp pad pulldown control register value

and tucked right onto the end of that last one, the page also gives you:

• acp63_sdw0-dma_intr_stat: DMA interrupt status array for ACP6.3 platform SoundWire manager-SW0 instance 🔥

lowkey a heads up: dmic_codec_dev, sdw_dma_dev, machines, subsystem_vendor, subsystem_device, and the acp63_sdw1_dma_intr_stat / acp70_sdw0_dma_intr_stat / acp70_sdw1_dma_intr_stat arrays are all sitting right there in the struct above — the Members list on this page just doesn't give them their own little spotlight moment 🙈 they're still in the synopsis tho, don't worry, nothing got deleted.

and that's the page!! this lil gem lives at ./sound/soc/amd/ps and it's dated October 2026 — mwah, bye, go write some sound driver code 💜🎀💅
