Requesting help.
I'm rebuilding my laptop with latest development lfs/blfs and am having
some kernel 4.19.8 issues.
My laptop has both wired and wireless network interfaces. The wired
interface is fine but the wireless interface is not being recognized.
For kernel 4.13.8, everything is fine. The firmware related kernel
options are:
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
iwlwifi-7260-17.ucode"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"
CONFIG_FIRMWARE_MEMMAP=y
and dmesg gives:
[ 1.516228] Bluetooth: hci0: Intel Bluetooth firmware file:
intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
[ 1.734116] Bluetooth: hci0: Intel Bluetooth firmware patch completed
and activated
[ 5.077436] iwlwifi 0000:01:00.0: loaded firmware version 17.459231.0
op_mode iwlmvm
For 4.19.8 I have:
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_EXTRA_FIRMWARE="intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq
iwlwifi-7260-17.ucode"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"
CONFIG_FIRMWARE_MEMMAP=y
There is no CONFIG_FIRMWARE_IN_KERNEL option for this kernel version.
dmesg now gives only:
[ 0.316853] platform regulatory.0: Direct firmware load for
regulatory.db failed with error -2
There are some things I found about something called regdb, but that
doesn't explain to me why the firmware isn't loading.
Any ideas?
