STRUCT IBM_PLATFORM_DUMP_PARAMS(9)

💅 struct ibm_platform_dump_params 💅

okay so bestie, welcome to the Kernel API Manual page for struct ibm_platform_dump_params — it’s literally the parameters (in and out) for ibm,platform-dump, and it’s giving “structured handoff energy” fr fr 🫶✨

💖 NAME 💖

struct ibm_platform_dump_params — Parameters (in and out) for ibm,platform-dump.

✨ SYNOPSIS ✨

here’s the whole struct, no cap — fields exactly as they are:

       struct ibm_platform_dump_params {
           struct rtas_work_area   *work_area;
           u32 buf_length;
           u32 dump_tag_hi;
           u32 dump_tag_lo;
           u32 sequence_hi;
           u32 sequence_lo;
           u32 bytes_ret_hi;
           u32 bytes_ret_lo;
           s32 status;
           struct list_head        list;
        };

🎀 Members 🎀

okay now the member-by-member vibe check 💅

• work_area — In: work area buffer for results.
• buf_length — In: work area buffer length in bytes.
• dump_tag_hi — In: Most-significant 32 bits of a Dump_Tag representing an id of the dump being processed.
• dump_tag_lo — In: Least-significant 32 bits of a Dump_Tag representing an id of the dump being processed.
• sequence_hi — In: Sequence number in most-significant 32 bits. Out: Next sequence number in most-significant 32 bits.
• sequence_lo — In: Sequence number in Least-significant 32 bits. Out: Next sequence number in Least-significant 32 bits.
• bytes_ret_hi — Out: Bytes written in most-significant 32 bits.
• bytes_ret_lo — Out: Bytes written in Least-significant 32 bits.
• status — Out: RTAS call status.
• list — Maintain the list of dumps are in progress. Can retrieve multiple dumps with different dump IDs at the same time but not with the same dump ID. This list is used to determine whether the dump for the same ID is in progress.
