Subject: [Buildroot] EUDEV takes a very long time to load the Wifi firmware
Date: Wed, 2 Jun 2021 20:00:15 -0300	[thread overview]
Message-ID: <CAOMZO5CcUAt1kBQ4W-nu6U4KP40UbSwa4ohFBq42dDNresANHw@mail.gmail.com> (raw)

Hi,

I am running kernel 5.12.4 on an imx6dl-pico-pi board with a QCA9377 Wifi chip.

Originally I was selecting BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y,
but that caused the QCA9377 firmware to be loaded only after almost 3
minutes.

Changing it to BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y caused the
QCA9377 firmware to be loaded very quickly as expected.

I am using a recent master version of Buildroot:
ab9ceea782c770acdb9a25d8601b12af261c8ccb

I am OK with using MDEV but just wanted to report it in case someone
knows if this is a known EUDEV issue.

Thanks,

Fabio Estevam
