In NixOS we need to use non-standard firmware path: we have no /lib.
|
|
Thanks to Ruediger Oertel.
|
|
The new firmware loader does not report an error to the kernel if a firmware file
is missing. This results in modprobe stalling for 60 seconds for each firmware
a module tries to load.

Instead of using multiple recursive Makefile.am files, use a single
Makefile.am that sets and builds all the basic suite of libraries and
binaries for udev. This reduces the number of files in the source tree, and
also reduces drastically the build time when using parallel-make.
With this setup, all the compile steps will be executed in parallel, and
just the linking stage will be (partially) serialised on the libraries
creation.

We currently search /lib/firmware and /lib/firmware/`uname -r` for firmware
files for device drivers loaded by the currently running kernel. These are
often packaged by distributions as a subpackage of the kernel or as a
separate package containing firmware. But these files cannot easily be
updated by third parties or sysadmins independently of that package.
This patch causes udev to also look for firmware files in an "updates"
directory, which is almost identical in purpose to the module-init-tools
"updates" directories insomuch as local changes can go in here and will
take preference over firmware supplied by any distribution.

[...] running the command
`make maintainer-clean' should not delete `configure' even if
`configure' can be remade using a rule in the Makefile. More
generally, `make maintainer-clean' should not delete anything that
needs to exist in order to run `configure' and then begin to build
the program. This is the only exception; `maintainer-clean' should
delete everything else that can be rebuilt.

Many thanks to Chris Spiegel for finding the still current vol_id
non-large-file-access bug, because of not including config.h.

We never used any of the libsysfs convenience features. Here we replace
it completely with 300 lines of code, which are much simpler and a bit
faster cause udev(d) does not open any syfs file for a simple event which
does not need any parent device information.

After beeing hit by proprietary applications which statically
link the LGPL'd libusb, which needs a patch to reflect the recent
kernel changes, I decided not to provide LGPL code anymore.

From: Bill Nottingham <notting@redhat.com>
Changed reading of firmware blob to mmap and let firmware_helper
follow the setting of the log level with UDEV_LOG.
