## x205ta-audio-FN_key-patch
EXPERIMENTAL Kernel changes for audio support
The section was created thanks to the great work done by those on  [UbuntuForums](https://ubuntuforums.org/showthread.php?t=2254322&page=126&p=13592053#post13592053).

The following steps must be done on the x205ta after installation to provide experimental audio support:

# Required lib and packages not installed by default
apt -y install git libssl-dev

# Retrieve the Linux kernel source tree fork - will take some time
git clone https://github.com/plbossart/sound.git -b experimental/codecs
cd sound

# Obtain the kernel config already done - otherwise you will have to run
# 'make localmodconfig', 'make menuconfig', and answer questions.

Re: Asus X205TA hardware support in Ubuntu
@syscl: Yeah, I'll probably release a 4.13 kernel when it's stable (probably around 3 or 10 september)
As for f2fs: Only way to find out is to try  I don't have much experience with f2fs on linux, on android it is real performance booster. Just keep in mind ext4 has been around for a long time so it is way more reliable and has much more support. If you want more information on performance I suggest you look at some of the articles Phoronix (Michael Larabel) has dedicated to the subject.

I wouldn't know what's causing the bluetooth issue you're having, could be a deficiency in my kernel (although my bluetooth mouse - a trust maxtrack - connects without too much issues). As mainstream 4.13 will deliver everything my kernel is and then some (more modules = broader support), you might have more success testing the official kernel instead:

@all: This is a guide to create a bootable ubuntu usb stick, install ubuntu and install a mainline kernel that supports everything that is available right now (sound,headphones,bluetooth,no freezes, etc). Finally you don't need those weird custom isos and suspicious scripts I created

PM me if you think the script is flawed/unclear

1. Download a 64bit ubuntu iso:
Code:
wget http://cdimage.ubuntu.com/xubuntu/releases/16.04/release/xubuntu-16.04.3-desktop-amd64.iso
2. Format a usb stick with a fat32 partition (for example with gparted) and mount the partition somewhere

3. Extract the iso to the chosen mountpoint
Code:
sudo 7z x xubuntu-16.04.3-desktop-amd64.iso -o/path/to/usbmountpoint/ #notice: no space after the -o flag
4. Download bootia32.efi and put it in /path/to/usbmountpoint/EFI/BOOT/
Code:
sudo wget https://github.com/jfwells/linux-asus-t100ta/raw/master/boot/bootia32.efi -O /path/to/usbmountpoint/EFI/BOOT/bootia32.efi
5. Unmount, and (re)boot the x205ta from the usb stick

6. Gain internet access
Code:
sudo cp -a /sys/firmware/efi/efivars/nvram* /lib/firmware/brcm/brcmfmac43340-sdio.txt; sudo rmmod brcmfmac; sudo modprobe brcmfmac
#(in my experience, this nvram does not have 5ghz support. this one does)
7. Install ubuntu (check the box to update packages during install, as it is needed to obtain efi-i386 grub libraries, which in turn are needed to boot ubuntu on the x205ta)

8. Reboot and let the x205ta boot into the installed ubuntu

9. Repeat step 6 to gain internet access again

10. Create a file called /etc/modprobe.d/50-x205ta.conf with the following contents:
Code:
#this quirk is needed to get headphones support in kernels >=4.13
options snd_soc_rt5645 quirk=0x31

#module snd_hdmi_lpe_audio breaks sound
blacklist snd_hdmi_lpe_audio

#module btsdio breaks wifi on suspend/resume
blacklist btsdio
11. Add some kernel boot parameters for the grub bootloader to use:
in the file /etc/default/grub ; append the line:
Code:
GRUB_CMDLINE_DEFAULT="quiet splash"
to:
Code:
GRUB_CMDLINE_DEFAULT="quiet splash intel_idle.max_cstate=1 button.lid_init_state=open"
#(intel_idle.max_cstate=1 to prevent freezes)
#(button.lid_init_state=open to prevent a suspend loop after closing/opening the lid)
12. Download Pierre Bossart's UCM files:
Code:
sudo mkdir -p /usr/share/alsa/ucm/chtrt5645
sudo rm -rf /usr/share/alsa/ucm/chtrt5645/{HiFi,chtrt5645}.conf
sudo wget https://raw.githubusercontent.com/plbossart/UCM/master/chtrt5645/HiFi.conf -O /usr/share/alsa/ucm/chtrt5645/HiFi.conf
sudo wget https://raw.githubusercontent.com/plbossart/UCM/master/chtrt5645/chtrt5645.conf -O /usr/share/alsa/ucm/chtrt5645/chtrt5645.conf
13. Download a >=v4.13 linux-image .deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/ (I'd choose a generic one):
Code:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb
#(if you want to install headers, download them too)
14. Install the .deb-file
Code:
sudo dpkg -i linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb
#(if desired, install headers in a similar manner but after step 15)
15. Reboot into the >=4.13 kernel

16. Presto manifesto ! (well, shoot, now that I look at it, still a lot of work to get linux on this machine, but it has gotten better...)


Go for the bonus points!:
As you might notice, bluetooth is not working and some (one) applications (kodi) dont have sound after suspend/resume.

Bluetooth:
Download the appropriate firmware file:
Code:
sudo wget https://raw.githubusercontent.com/harryharryharry/x205ta-iso2usb-files/master/BCM43341B0.hcd -O /lib/firmware/brcm/BCM43341B0.hcd
Create a systemd service-file /etc/systemd/system/btattach.service with the following contents:
Code:
[Unit]
Description=Btattach

[Service]
Type=simple
ExecStart=/usr/bin/btattach --bredr /dev/ttyS1 -P bcm
ExecStop=/usr/bin/killall btattach

[Install]
WantedBy=multi-user.target
And enable it (and restart the bluetooth service):
Code:
sudo systemctl enable btattach --now
sudo systemctl restart bluetooth
Kodi:
To retain sound in kodi after suspend, create a file /etc/systemd/system/resume-fix-pulseaudio@.service with the following contents (read note below on how this does NOT work in ubuntu):
Code:
[Unit]
Description=Fix PulseAudio after resume from suspend
After=suspend.target

[Service]
User=%I
Type=oneshot
Environment="XDG_RUNTIME_DIR=/run/user/%U"
ExecStart=/usr/bin/pasuspender /bin/true

[Install]
WantedBy=suspend.target
And enable the service:
Code:
systemctl enable resume-fix-pulseaudio@harry #change to your own username
Note: I got this service file off the always excellent Arch Linux wiki page. While this systemd-file does work fine in other distros, for some reason ubuntu does not accept the %U parameter, so with ubuntu change it to whatever uid your username has (find it by running: ls /run/user).
So if your uid is 1000, append the line in the systemd-file to:
Environment="XDG_RUNTIME_DIR=/run/user/1000"

为了使用WIFI的5GHz频率，有很多事是要注意的：
1、无线网卡是否支持5GHz。

2、需要CRDA可执行文件：/sbin/crda

3、需要CRDA目录：/lib/crda/

4、udev文件：/lib/udev/rules.d/85-regulatory.rules


## x205ta-Wireless-Enable
Do I need to install a wireless patch for ASUS X205TA after upgrading the kernel?

Looking at the Debian wiki WiFi section it has a link to a WiFi patch and under it says that WiFi works in kernel > 4.0.

Do I still need the WiFi patch if I upgrade to kernel 4.0?

No patch needed for 4* kernels. We need these two files in the right place for WiFi to work on this device.

/lib/firmware/brcm/brcmfmac43340-sdio.bin
/lib/firmware/brcm/brcmfmac43340-sdio.txt
The first one was present & correctly located when I installed 16.04. Previously we used a file from Android and this is still mentioned in old guides, but if you don't have it, you can now get it from the Linux firmware repository:

sudo apt-get install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
This creates a new directory - copy the correct file from it to the right place:

sudo cp linux-firmware/brcm/brcmfmac43340-sdio.bin lib/firmware/brcm/brcmfmac43340-sdio.bin
you might want to delete the cloned directory after that, as it is quite big.

The other file is already in the system but in the wrong place. It needs to be copied to the same directory as the .bin file and renamed like this:

sudo cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt
Wi-Fi works after reboot :)

	EXPERIMENTAL Kernel changes for audio support
	The section was created thanks to the great work done by those on [UbuntuForums](https://ubuntuforums.org/showthread.php?t=2254322&page=126&p=13592053#post13592053).

	The following steps must be done on the x205ta after installation to provide experimental audio support:

	# Required lib and packages not installed by default
	apt -y install git libssl-dev

	# Retrieve the Linux kernel source tree fork - will take some time
	git clone https://github.com/plbossart/sound.git -b experimental/codecs
	cd sound

	# Obtain the kernel config already done - otherwise you will have to run
	# 'make localmodconfig', 'make menuconfig', and answer questions.
	# Original file from:
	# ftp://x205ta.myftp.org:1337/kernel/.config
	wget http://lopaka.github.io/files/instructions/x205ta.config -O .config

	# reverse patch the commit that causes the keyboard to malfunction
	git diff 3ae02c1^ 3ae02c1 \| patch -Rp1

	# Add patch that attempts to fix non-functioning FN-keys

	make modules_install

	# Install kernel to the boot dir
	export KERNELRELEASE=$(<include/config/kernel.release)
	cp -va arch/x86/boot/bzImage /boot/vmlinuz-$KERNELRELEASE

	# Build initramfs
	update-initramfs -c -k $KERNELRELEASE

	# Rebuild /boot/grub/grub.cfg

	-----------
	Re: Asus X205TA hardware support in Ubuntu
	@syscl: Yeah, I'll probably release a 4.13 kernel when it's stable (probably around 3 or 10 september)
	As for f2fs: Only way to find out is to try I don't have much experience with f2fs on linux, on android it is real performance booster. Just keep in mind ext4 has been around for a long time so it is way more reliable and has much more support. If you want more information on performance I suggest you look at some of the articles Phoronix (Michael Larabel) has dedicated to the subject.

	I wouldn't know what's causing the bluetooth issue you're having, could be a deficiency in my kernel (although my bluetooth mouse - a trust maxtrack - connects without too much issues). As mainstream 4.13 will deliver everything my kernel is and then some (more modules = broader support), you might have more success testing the official kernel instead:

	@all: This is a guide to create a bootable ubuntu usb stick, install ubuntu and install a mainline kernel that supports everything that is available right now (sound,headphones,bluetooth,no freezes, etc). Finally you don't need those weird custom isos and suspicious scripts I created

	PM me if you think the script is flawed/unclear

	1. Download a 64bit ubuntu iso:
	Code:
	wget http://cdimage.ubuntu.com/xubuntu/releases/16.04/release/xubuntu-16.04.3-desktop-amd64.iso
	2. Format a usb stick with a fat32 partition (for example with gparted) and mount the partition somewhere

	3. Extract the iso to the chosen mountpoint
	Code:
	sudo 7z x xubuntu-16.04.3-desktop-amd64.iso -o/path/to/usbmountpoint/ #notice: no space after the -o flag
	4. Download bootia32.efi and put it in /path/to/usbmountpoint/EFI/BOOT/
	Code:
	sudo wget https://github.com/jfwells/linux-asus-t100ta/raw/master/boot/bootia32.efi -O /path/to/usbmountpoint/EFI/BOOT/bootia32.efi
	5. Unmount, and (re)boot the x205ta from the usb stick

	6. Gain internet access
	Code:
	sudo cp -a /sys/firmware/efi/efivars/nvram* /lib/firmware/brcm/brcmfmac43340-sdio.txt; sudo rmmod brcmfmac; sudo modprobe brcmfmac
	#(in my experience, this nvram does not have 5ghz support. this one does)
	7. Install ubuntu (check the box to update packages during install, as it is needed to obtain efi-i386 grub libraries, which in turn are needed to boot ubuntu on the x205ta)

	8. Reboot and let the x205ta boot into the installed ubuntu

	9. Repeat step 6 to gain internet access again

	10. Create a file called /etc/modprobe.d/50-x205ta.conf with the following contents:
	Code:
	#this quirk is needed to get headphones support in kernels >=4.13
	options snd_soc_rt5645 quirk=0x31

	#module snd_hdmi_lpe_audio breaks sound
	blacklist snd_hdmi_lpe_audio

	#module btsdio breaks wifi on suspend/resume
	blacklist btsdio
	11. Add some kernel boot parameters for the grub bootloader to use:
	in the file /etc/default/grub ; append the line:
	Code:
	GRUB_CMDLINE_DEFAULT="quiet splash"
	to:
	Code:
	GRUB_CMDLINE_DEFAULT="quiet splash intel_idle.max_cstate=1 button.lid_init_state=open"
	#(intel_idle.max_cstate=1 to prevent freezes)
	#(button.lid_init_state=open to prevent a suspend loop after closing/opening the lid)
	12. Download Pierre Bossart's UCM files:
	Code:
	sudo mkdir -p /usr/share/alsa/ucm/chtrt5645
	sudo rm -rf /usr/share/alsa/ucm/chtrt5645/{HiFi,chtrt5645}.conf
	sudo wget https://raw.githubusercontent.com/plbossart/UCM/master/chtrt5645/HiFi.conf -O /usr/share/alsa/ucm/chtrt5645/HiFi.conf
	sudo wget https://raw.githubusercontent.com/plbossart/UCM/master/chtrt5645/chtrt5645.conf -O /usr/share/alsa/ucm/chtrt5645/chtrt5645.conf
	13. Download a >=v4.13 linux-image .deb from http://kernel.ubuntu.com/~kernel-ppa/mainline/ (I'd choose a generic one):
	Code:
	wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.13/linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb
	#(if you want to install headers, download them too)
	14. Install the .deb-file
	Code:
	sudo dpkg -i linux-image-4.13.0-041300-generic_4.13.0-041300.201709031731_amd64.deb
	#(if desired, install headers in a similar manner but after step 15)
	15. Reboot into the >=4.13 kernel

	16. Presto manifesto ! (well, shoot, now that I look at it, still a lot of work to get linux on this machine, but it has gotten better...)


	Go for the bonus points!:
	As you might notice, bluetooth is not working and some (one) applications (kodi) dont have sound after suspend/resume.

	Bluetooth:
	Download the appropriate firmware file:
	Code:
	sudo wget https://raw.githubusercontent.com/harryharryharry/x205ta-iso2usb-files/master/BCM43341B0.hcd -O /lib/firmware/brcm/BCM43341B0.hcd
	Create a systemd service-file /etc/systemd/system/btattach.service with the following contents:
	Code:
	[Unit]
	Description=Btattach

	[Service]
	Type=simple
	ExecStart=/usr/bin/btattach --bredr /dev/ttyS1 -P bcm
	ExecStop=/usr/bin/killall btattach

	[Install]
	WantedBy=multi-user.target
	And enable it (and restart the bluetooth service):
	Code:
	sudo systemctl enable btattach --now
	sudo systemctl restart bluetooth
	Kodi:
	To retain sound in kodi after suspend, create a file /etc/systemd/system/resume-fix-pulseaudio@.service with the following contents (read note below on how this does NOT work in ubuntu):
	Code:
	[Unit]
	Description=Fix PulseAudio after resume from suspend
	After=suspend.target

	[Service]
	User=%I
	Type=oneshot
	Environment="XDG_RUNTIME_DIR=/run/user/%U"
	ExecStart=/usr/bin/pasuspender /bin/true

	[Install]
	WantedBy=suspend.target
	And enable the service:
	Code:
	systemctl enable resume-fix-pulseaudio@harry #change to your own username
	Note: I got this service file off the always excellent Arch Linux wiki page. While this systemd-file does work fine in other distros, for some reason ubuntu does not accept the %U parameter, so with ubuntu change it to whatever uid your username has (find it by running: ls /run/user).
	So if your uid is 1000, append the line in the systemd-file to:
	Environment="XDG_RUNTIME_DIR=/run/user/1000"

	解决linux系统WIFI无法使用5GHz频率的问题
	https://blog.csdn.net/subfate/article/details/51882322

	为了使用WIFI的5GHz频率，有很多事是要注意的：
	1、无线网卡是否支持5GHz。

	2、需要CRDA可执行文件：/sbin/crda

	3、需要CRDA目录：/lib/crda/

	4、udev文件：/lib/udev/rules.d/85-regulatory.rules
	Do I need to install a wireless patch for ASUS X205TA after upgrading the kernel?

	Looking at the Debian wiki WiFi section it has a link to a WiFi patch and under it says that WiFi works in kernel > 4.0.

	Do I still need the WiFi patch if I upgrade to kernel 4.0?

	------------------
	No patch needed for 4* kernels. We need these two files in the right place for WiFi to work on this device.

	/lib/firmware/brcm/brcmfmac43340-sdio.bin
	/lib/firmware/brcm/brcmfmac43340-sdio.txt
	The first one was present & correctly located when I installed 16.04. Previously we used a file from Android and this is still mentioned in old guides, but if you don't have it, you can now get it from the Linux firmware repository:

	sudo apt-get install git
	git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
	This creates a new directory - copy the correct file from it to the right place:

	sudo cp linux-firmware/brcm/brcmfmac43340-sdio.bin lib/firmware/brcm/brcmfmac43340-sdio.bin
	you might want to delete the cloned directory after that, as it is quite big.

	The other file is already in the system but in the wrong place. It needs to be copied to the same directory as the .bin file and renamed like this:

	sudo cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt
	Wi-Fi works after reboot :)
