STRUCT CXL_DPA_PARTITION(9)

💖 NAME 💖

struct cxl_dpa_partition — bestie, this is the DPA partition descriptor, like, the little ID card for one slice of DPA. Welcome to the Kernel API Manual, we're getting into it ✨

🌸 SYNOPSIS 🌸

struct cxl_dpa_partition {
    struct resource res;
    struct cxl_dpa_perf perf;
    enum cxl_partition_mode mode;
 };

okay so, three fields, no notes, she's giving minimal and iconic 🎀

🦋 Members 🦋

• res — this is your shortcut straight to the partition in the DPA resource tree, aka cxlds->dpa_res. literally the pointy finger that says "the partition is right there" 💅
• perf — the performance attributes of the partition, served fresh from CDAT 📊 obsession-worthy, honestly.
• mode — the operation mode for the DPA capacity. like ram, pmem, dynamic... — which one it's in is very much main character energy of the field 🌈
