FPGA MANAGER FLAGS(9)

🎀 FPGA Manager flags 🎀

okay so bestie, this page is from the Kernel API Manual, section 9, and it's literally the glow-up guide for the fpga_image_info->flags field. These are the flags used in that field, and yes, every single one is doing something. ✨

• FPGA_MGR_PARTIAL_RECONFIG — do partial reconfiguration if supported. if it's not supported, that's a vibe check fail, not on you. 💅
• FPGA_MGR_EXTERNAL_CONFIG — the FPGA has been configured prior to Linux booting. so it's been main character since before the kernel even showed up. 👑
• FPGA_MGR_ENCRYPTED_BITSTREAM — indicates the bitstream is encrypted. locked down, secretive, very mysterious. 💜
• FPGA_MGR_BITSTREAM_LSB_FIRST — SPI bitstream bit order is LSB first. bit order tea, no cap. 🦋
• FPGA_MGR_COMPRESSED_BITSTREAM — the FPGA bitstream is compressed. small file, big energy. 🔥

🔗 SEE ALSO 🔗

like, go read these next, bestie — they're giving essential lore:

Kernel file ./include/linux/fpga/fpga-mgr.h, plus:

• enum fpga_mgr_states(9)
• struct fpga_image_info(9)
• struct fpga_compat_id(9)
• struct fpga_manager_info(9)
• struct fpga_manager_ops(9)
• struct fpga_manager(9)

ngl this page is short but iconic. don't sleep on the flags. 💖

mwah 💖 this cutie comes from source ./include/linux/fpga and is dated October 2026 — periodt. 🫶
