STRUCT X86_INIT_MPPARSE(9)

🌸 NAME 🌸

okay bestie, this is the struct x86_init_mpparse(9) page from the Kernel API Manual. It's giving platform-specific mpparse ops energy: a struct full of four function pointers that let the platform do its own little mpparse things. no cap. 💅

✨ SYNOPSIS ✨

here's the struct in all its glory, copied exactly because we do not mess with code, periodt:

       struct x86_init_mpparse {
           void (*setup_ioapic_ids)(void);
           void (*find_mptable)(void);
           void (*early_parse_smp_cfg)(void);
           void (*parse_smp_cfg)(void);
        };

💅 Members 💅

• setup_ioapic_ids — the platform specific ioapic id override. like, it's the hook for overriding the ioapic id on a platform. slay.
• find_mptable — finds the MPTABLE early to reserve the memory region. early bird behavior, honestly. 🐦
• early_parse_smp_cfg — parses the SMP configuration data early, before initmem_init. timing is everything, bestie. ⏰
• parse_smp_cfg — parses the SMP configuration data. that's it, that's the vibe. ✨

🦋 SEE ALSO 🦋

bestie, if you wanna go down the rabbit hole, the kernel file is ./arch/x86/include/asm/x86_init.h, and these related structs/enums are all right there:

• struct x86_init_resources(9)
• struct x86_init_irqs(9)
• struct x86_init_oem(9)
• struct x86_init_paging(9)
• struct x86_init_timers(9)
• struct x86_init_iommu(9)
• struct x86_init_pci(9)
• struct x86_hyper_init(9)
• struct x86_init_acpi(9)
• struct x86_guest(9)
• struct x86_init_ops(9)
• struct x86_cpuinit_ops(9)
• struct x86_legacy_devices(9)
• enum x86_legacy_i8042_state(9)
• struct x86_legacy_features(9)
• struct x86_hyper_runtime(9)
• struct x86_platform_ops(9)

iykyk, that's the whole friend group. 🫶

the source/version line says ./arch/x86/include/asm, and the date says October 2026 — so yeah, struct x86_init_mpparse(9) is the manual, and that's the cute lil sign-off. mwah 💖
