process_ldr_command_stream(9)

✨ process_ldr_command_stream(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the process_ldr_command_stream page and honestly? it's giving "firmware whisperer" 💅

---

🌸 NAME 🌸

process_ldr_command_stream — processes the LDR firmware image and populates the firmware sections. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

int process_ldr_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 , u32 **boot_conf_ptr );

literally the whole signature, no cap 🫶

---

🎀 ARGUMENTS 🎀

bestie, there are six of these and you need to know every single one, so let's go 🔥

• pvr_dev — device pointer. the main character of this whole function, fr fr 👑
• fw — pointer to the firmware image. this is the source material 📀
• fw_code_ptr — pointer to the FW code section ✨
• fw_data_ptr — pointer to the FW data section 🍓
• fw_core_code_ptr — pointer to the FW coremem code section 💜
• fw_core_data_ptr — pointer to the FW coremem data section 🌈
• boot_conf_ptr — pointer to the boot config argument pointer. yes it's a pointer to a pointer, don't @ me, that's just how it is 🙈

---

💀 RETURN 💀

• 0 on success 🎉 slay
• -EINVAL on any error in the LDR command stream 💔 it's giving "something went wrong in the command stream" and that's the whole story

---

🔍 SEE ALSO 🔍

• Kernel file ./drivers/gpu/drm/imagination/pvr_fw_meta.c — go read it, iykyk 📖
• pvr_meta_cr_read32(9) — the other iconic one, linked up like the bestie it is 🫶

---

ngl if you get -EINVAL back, that means the LDR command stream had an error somewhere. not a vibe, but at least now you know 💅

mwah 💋 that's the whole page, written from ./drivers/gpu/drm/imagination, dated October 2026, and manual-section-coded to the very end. periodt. 💖🎀🦋
