SVC_NUM_DATA_IN_FIFO(9)

💅 SVC_NUM_DATA_IN_FIFO 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for SVC_NUM_DATA_IN_FIFO, and it is literally the shortest little icon in the stratix10 firmware universe, so grab a boba and let's go 🧋✨

---

🌸 NAME 🌸

SVC_NUM_DATA_IN_FIFO — number of struct stratix10_svc_data in the FIFO 🎀

---

✨ SYNOPSIS ✨

SVC_NUM_DATA_IN_FIFO

that's it. that's the whole synopsis. no arguments, no flags, no drama. she's a constant and she knows it 💅

---

💖 DESCRIPTION 💖

so the headline says this one is the number of struct stratix10_svc_data in the FIFO — but the description goes off and introduces the rest of the little constant friend group instead, and honestly? slay. here's who's who in the group chat 🫶

• SVC_NUM_CHANNEL — number of channel supported by service layer driver. that's her. that's the count of channels the service layer driver can handle 🌈
• FPGA_CONFIG_DATA_CLAIM_TIMEOUT_MS — this is the "claim it back" timeout, ms edition ⏱️ it's how you claim back the submitted buffer(s) from the secure world so the FPGA manager can reuse them, or so the buffer(s) get freed when all bit-stream data had be send 🔥
• FPGA_CONFIG_STATUS_TIMEOUT_SEC — the poll timer for the FPGA configuration status 👑 the service layer will return error to FPGA manager when timeout occurs. and the timeout is set to 30 seconds (30 * 1000) at Intel Stratix10 SoC. no cap, that's the number 🍓

ngl, this page's NAME and DESCRIPTION are kind of a vibe check mismatch — the description is out here documenting the sibling constants. but every one of them is real and every one is listed, so we keep them all 💀💜
