CONFIG_DRM_EMGD=y
Return to section 3.2 step 7 to continue compiling the Kernel.

Intel®
3.4 Enable LPE and ISP Firmware and Drivers
This section describes the steps to enable LPE firmware/driver and ISP firmware/driver
in the kernel.
3.4.1 Install LPE firmware
1. Extract BYT_LSP_3.10_LPE_FIRMWARE_2014-01-16.tar.bz2
tar -xjf BYT_LSP_3.10_LPE_FIRMWARE_2014-01-16.tar.bz2
2. Depending on the Intel®
CRB SSP 2 port mode, either master or slave is to be
used. The Audio AK4614 AIC jumper (J119) shall be configured accordingly,
please refer Section 2.2 BIOS & Board Configuration for the configuration settings.
3. Copy the LPE firmware file fw_sst_0f28.bin-i2s_master or fw_sst_0f28.bin-
i2s_slave or fw_sst_0f28.bin-tdm_master or fw_sst_0f28.bin-tdm_slave
(depending on the code mode setup) in to /lib/firmware of the Tizen* OS you
have created.
4. Rename only the desired firmware file to fw_sst_0f28.bin.
Note:
1. The fw_sst_0f28.bin binary image is targeted to use for SSP Port 2 only.
2. The fw_sst_0f28.bin only needs to be copied once.
5. Current LPE driver has implemented a method to select I2S mode or TDM mode
during kernel boot time. By default, the driver will select I2S mode.
Below shows the setting method:
a) To select I2S mode, edit the kernel boot up command in file
“/boot/loader/entries/vmlinuz-kernel.conf” at the end of “append”
line, add in “snd_soc_sst_platform.useMultiChannels=2”.
b) To select TDM mode, edit the kernel boot up command in file
“/boot/loader/entries/vmlinuz-kernel.conf” at the end of “append”
line, add in “snd_soc_sst_platform.useMultiChannels=8”.
c) To verify the correct configuration is passed to the LPE driver, after
system boot up, type “dmesg | grep “useMulti”” in the Linux console
and check with the driver print message.
d) After selection, the corresponding LPE firmware binary will need to be
renamed to fw_sst_0f28.bin and placed in the /lib/firmware directory.
e) Current LPE driver only support playback of 8 channels audio source for
TDM mode.
6. Current LPE driver only support playback of 8 channels audio source for TDM
mode.

a) To enable support of less than 8 channels audio wave file playback, an ALSA
virtual device is required to be created. Go to “/etc/asound.conf” file and
edit to add as below :
pcm. Xto8{
type route
slave {
pcm "hw:0,0"
channels 8
}
ttable.0.0 1
ttable.1.1 1
ttable.2.2 1
ttable.3.3 1
ttable.4.4 1
ttable.5.5 1
ttable.6.6 1
ttable.7.7 1
}
b) To make Xto8 virtual device to be the default playback device in TDM mode
only (remember to undo this when switching back to I2S mode), go to
“/etc/asound.conf” file and modify the “pcm.!default” as below :
pcm. !default {
#type hw
#card 0
type plug
slave.pcm Xto8
}

Intel®
3.4.2 Build Kernel with LPE Driver
