The refs carried paths from a revision newer than source_commit, so the profiles described two trees at once. rvvm is the plain case: the file is src/rvvm.c at the pin and src/core/rvvm.c at the revision its refs were written against, and citing the second against the first reads as a file that vanished. The diagnostic added for this named all three in one pass, and each cost one line. rvvm 3 refs, boom3 4, applewin 1, all anchored.

# RVVM emulates a RISC-V machine (rv64imafdcb or rv32ima). The libretro core
|
|
# loads a .rvvm plain-text config file specifying bootrom, kernel, nvme drives,
|
|
# memory, CPU mode, cmdline, and framebuffer resolution.
|
|
#
|
|
# The core does NOT use the RetroArch system directory. All firmware paths are
|
|
# specified in the .rvvm config file and resolved relative to its directory.
|
|
# The core chdir()s to the .rvvm file's parent before initializing the VM.
|
|
#
|
|
# The .rvvm config format (parsed by retro_load_game):
|
|
# bootrom=/path/to/fw_payload.bin
|
|
# kernel=/path/to/Image
|
|
# nvme=/path/to/rootfs.img
|
|
# mem=512
|
|
# smp=2
|
|
# rv64
|
|
# cmdline=root=/dev/nvme0n1 rootflags=discard rw console=tty0
|
|
#
|
|
# The libretro binding uses an older RVVM API (rvvm_load_bootrom, 4-param
|
|
# rvvm_create_machine) that has been renamed in the current upstream
|
|
# (rvvm_load_firmware, 3-param rvvm_create_machine). The binding may not
|
|
# compile against RVVM HEAD without updates.

M-mode firmware loaded at 0x80000000. Typically OpenSBI with U-Boot

payload (fw_payload.bin) or standalone (fw_jump.bin). Referenced by

the bootrom= key in the .rvvm config.

S-mode kernel payload loaded at offset 0x200000 (rv64) or 0x400000

Custom Flattened Device Tree. The core auto-generates a DTB based on
|
|
machine configuration. The libretro binding does not parse a dtb= key
|
|
in the .rvvm config, so this is only usable via the standalone CLI
|
|
(-dtb flag).

info_firmware_count: >

.info declares 0 firmware. Correct: the core loads firmware via
|
|
user-specified paths in the .rvvm config, not from system_dir.
