Issue #3041 has been updated by liweitianux.

Category set to Kernel

From zrj:
(1) Having support for multiple embedded firmware images in one module is useful, and \
I doubt we would want to move firmware handling to userland. (2) Having firmware as \
kernel module allows to load it in "/boot/loader.conf" before kernel boots for early \
modules, like radeon(4) or network card drivers.

Hello,

this patch removes possibility of embedding more than one firmware image in one \
kernel module through the parent reference in the firmware_register() function.

This patch is a preparation for firmware subsystem modification for moving firmware \
images from kernel modules to userland.

The mechanism is not used and it can be functionally fully replaced by putting each \
firmware image in its own module.

Removing the functionality significantly simplifies handling of firmware images. If \
firmware images are moved to userland the logical grouping of modules could be \
expressed by putting the related firmware images into one directory if needed.
