From mboxrd@z Thu Jan 1 00:00:00 1970 From: Yann E. MORIN Date: Tue, 3 Mar 2020 22:28:53 +0100 Subject: [Buildroot] [PATCH] package/linux-firmware: fix symlink support In-Reply-To: <20200303133356.859800-1-antoine.tenart@bootlin.com> References: <20200303133356.859800-1-antoine.tenart@bootlin.com> Message-ID: <20200303212853.GD12449@scaer> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Antoine, All, On 2020-03-03 14:33 +0100, Antoine Tenart spake thusly: > Since Linux-firmware's commit 9cfefbd7fbda ("Remove duplicate symlinks") > symlinks aren't distributed anymore. They are rather created at > installation time by a script provided in the project, copy-firmware.sh. > The description of the symlinks is done in the WHENCE file. Since the > bump to version 20200122, in commit 48cc1a89ae04, installation for many > firmwares was broken as Buildroot tried to install missing symlinks from > Linux-firmware. > > The fix is not only to remove now missing symlinks, but to add logic to > create those symlinks as kernel modules will depend on them. The > solution taken by this patch is to create dynamically symlinks based on > their description in the WHENCE file *and* only if the file they'll > point to was installed in the target directory. > > Fixes: 48cc1a89ae04 ("package/linux-firmware: bump to version 20200122") > Cc: james.hilliard1 at gmail.com > Signed-off-by: Antoine Tenart I did find a problem with some symlinks that is not created. Link: cxgb4/t4fw.bin -> t4fw-1.24.11.0.bin The target is itself in the cxgb4/ directory, so your code does not catch it as an isntalled blob, and thus does not create the symlink. I anyway applied, because it at least fixes the build by dropping the entries tht no longer exist as they are symlinks. So this patch is just a partial fix. Care to send an update to also account for the kind of symlinks above? Thanks! Regards, Yann E.
