STRUCT CXL_ENDPOINT_DECODER(9)

💅 struct cxl_endpoint_decoder(9) — Kernel API Manual 🫶

✨ NAME ✨

okay so bestie, this is the Kernel API Manual glow-up for struct cxl_endpoint_decoder — literally the Endpoint / SPA to DPA decoder. That's the whole name, and yes it ate. 💖

🦋 SYNOPSIS 🦋

Here's the struct exactly as it shows up, no edits, no vibes-based changes:

       struct cxl_endpoint_decoder {
           struct cxl_decoder cxld;
           struct resource *dpa_res;
           resource_size_t skip;
           enum cxl_decoder_state state;
           int part;
           int pos;
        };

🌸 Members 🌸

• cxld — base cxl_decoder_object, the foundation of the whole look ✨
• dpa_res — actively claimed DPA span of this decoder, periodt
• skip — offset into dpa_res where cxld.hpa_range maps
• state — autodiscovery state, lowkey important
• part — partition index this decoder maps
• pos — interleave position in cxld.region
