pvr_fw_proc...mmand_stream(9)

🎀 NAME 🎀

ok so this page is pvr_fw_proc...mmand_stream(9) from the Kernel API Manual — yes the name is literally abbreviated with dots like that, she's mysterious, we respect it 💅 — and it's all about pvr_fw_process_elf_command_stream: the function that takes your ELF firmware image and populates the firmware sections. it's giving "unpacking the firmware care package" energy.

---

✨ SYNOPSIS ✨

int pvr_fw_process_elf_command_stream (struct pvr_device *pvr_dev ,
const u8 *fw , u8 *fw_code_ptr , u8 *fw_data_ptr , u8 *fw_core_code_ptr
, u8 *fw_core_data_ptr );

that's the whole signature bestie, no cap, every parameter is u8 * except the first one 🔥

🦋 ARGUMENTS 🦋

six things go in, okay? let's meet them:

• pvr_dev — the device pointer. yes queen, the actual GPU device, she's the main character here 👑
• fw — pointer to the firmware image. the raw goods, the blueprint 🎀
• fw_code_ptr — pointer to the FW code section. the code part of things 💖
• fw_data_ptr — pointer to the FW data section. the data part, lowkey the other half of the duo 🌸
• fw_core_code_ptr — pointer to the FW coreslot... no wait, FW coremem code section 💅 coremem, don't forget it
• fw_core_data_ptr — pointer to the FW coremem data section ✨

heads up: these are pointers to sections — the function populates firmware sections, it doesn't invent them out of nowhere. you bring the storage, she fills it in 🫶

💀 RETURN 💀

what you get back:

• 0 — success, slay, everything worked, go off 🎉
• -EINVAL — on any error in the ELF command stream 😭 any error, we don't discriminate, it's all -EINVAL in this house
