The linux-firmware packages on Gentoo, Fedora, Arch, and others compress the firmware files. This works well with CONFIG_FW_LOADER_COMPRESS, but does not work with CONFIG_EXTRA_FIRMWARE. This patch allows the build system to decompress firmware files specified by CONFIG_EXTRA_FIRMWARE. PATCH 1/2 adds decompression routines next to the compression routines in scripts/Makefile.lib. That patch is then used by PATCH 2/2 to decompress files before compiling them into the kernel. The patch works by copying or decompressing the specified firmware files into the build directory, then compiling them in from there. I would prefer to not copy any uncompressed files, but I have not found a clean way to do that. drivers/base/firmware_loader/Kconfig | 5 ++++- drivers/base/firmware_loader/builtin/.gitignore | 5 ++++- drivers/base/firmware_loader/builtin/Makefile | 16 ++++++++++++---- scripts/Makefile.lib | 6 ++++++ 4 files changed, 26 insertions(+), 6 deletions(-) -- 2.41.0
