Asus Transformer book T200TA

Question

Hello,
I'm trying to put an Archlinux on the Asus Transformer book T200TA, and I will share here my progress. I will take note of a lot of things, when I manage to do something or when something does not work. And if you have any ideas to make something works, tell me !
Current status (for TL;DR)
- Boot under archiso : Working with patch
- Boot Archlinux on the keyboard's HDD : Working by putting boot and efi partition on the internal memory
- Virtualization of Windows 8.1 under linux : Partially working only with a 64 bit linux as host
- SD card : Working with patch
- Graphics : Working
- Random freezes : Fixed ?. Didn't experienced any since my new installation with linux 4.0
- xhci_hcd bug at boot ; Work in USB2 mode only
- Backlight control : Working
- Sound : Work on both headphone and speakers in stereo but you have to edit an alsa config file for enabling sound on one or both output and for setting the sound level. Microphone not tested.
- Wifi : Not working
- Bluetooth : Not working: Not working
- Battery indicator : Working With kernell patch
- Touchpad : Partially working : Only one finger and very unpleasant because the cursor move a little before you click.
- Touchscreen : Partially working : Works randomly and seems to not release click when you remove your finger.

The T200TA has a lot on common with the T100TA, so, much of my fixes come from this computer (as it has been release one year before and the T200 is currently pretty new).

Boot under archiso
If you try to boot, it will not work. Because, as T100, it search only for 32bit efi (even if the cpu can handle 64bit OS). You can do like him.
Or you can do like me, I think it's easier, but really dirty (it's not a full script, execute it only part by part) :
## Create working directory
mkdir work
cd work
## Build grub and get missing bootloader files bootia32.efi
git clone git://git.savannah.gnu.org/grub.git
cd grub
./autogen.sh
export EFI_ARCH=i386
./configure --with-platform=efi --target=${EFI_ARCH} --program-prefix=""
make
cd grub-core
../grub-mkimage -d . -o bootia32.efi -O i386-efi -p /boot/grub ntfs hfs appleldr boot cat efi_gop efi_uga elf fat hfsplus iso9660 linux keylayouts memdisk minicmd part_apple ext2 extcmd xfs xnu part_bsd part_gpt search search_fs_file chain btrfs loadbios loadenv lvm minix minix2 reiserfs memrw mmap msdospart scsi loopback normal configfile gzio all_video efi_gop efi_uga gfxterm gettext echo boot chain eval
cp bootia32.efi ../../bootia32.efi
cd ../../
rm -r grub
##Get all file from the current archlinux install iso
#Search and replace all XXXX.XX.XX by the current release date and /dev/sdX by your usb key address. If you find a way to extract both partion from iso without dd, it should be faster than that, so tell me if you know how to do that.
dd bs=4M if="archlinux-XXXX.XX.XX-dual.iso" of=/dev/sdX
mkdir usb
mkdir newiso
# Unplug and replug your usb key and wait a little if mount doens't work :
mount /dev/sdX2 ./usb
cp -r usb/* newiso/
sync
umount usb
mount /dev/sdX1 ./usb
cp -r usb/* newiso/
sync
umount usb
rmdir usb
## Prepare new usb key content
mv bootia32.efi newiso/EFI/boot/
mkdir -p newiso/boot/grub
echo "
menuentry 'Arch Linux i686'{
echo 'Loading Linux core repo kernel ...'
linux /arch/boot/i686/vmlinuz nomodeset archisobasedir=arch archisolabel=ARCHISO

## Prepare the usb key partition

# Default last sector

c # change partion's name
ARCHISO
w # Write modifications on the disk
Y # Proceed
mkfs.fat -F 32 /dev/sdX1
echo mtools_skip_check=1 >> ~/.mtoolsrc
mlabel -i /dev/sdX1 -s ::ARCHISO
rm ~/.mtoolsrc
## Copy files to the usb key
mkdir usb
mount /dev/sdX1 usb
cp -r newiso/* usb/
sync
umount usb
rmdir usb
## Cleaning
cd ../
rm -r work
A better way of fixing that should be building a x86 version of the file `PreLoader` from the repo `git://git.kernel.org/pub/scm/linux/kernel/git/jejb/efitools.git` because this file is renamed as `bootx64.efi` during the archiso creation, and the missing file is the x86 equivalent : `bootia32.efi`. Anyway, I didn't manage to build it, so I gave up this path. Tell me if you find something better.
Boot Archlinux on the keyboard's HDD
I cannot currently use this computer under linux for everyday, but I need a linux to work or dev. And I have to admit that the windows UI is much better for touchscreen than any linux desktop that I tried. The internal memory is only 30GB. So I let Windows 8.1 on internal memory for "tablet mode" and linux on hard drive for "netbook mode".
I didn't find any way to make the computer boot to the hard drive (or the micro usb card of 64GB), the efi-bios don't see them (the HDD is pluged in usb 3.0, but even in USB 2.0 mode it does the same).
To make it work, you have to put the boot and efi partition on the internal memory :
- Create a boot parition (100mo ext2) on the internal memory or use the windows rescue partition (300mo, ntfs, ~86%used after grub and vmlinuz installation). And during your installation process, mount it at /boot (/dev/mmcblkpX)
- Use the windows EFI parition (100mo fat32) and mount it to /boot/efi (/dev/mmcblkpY)
- Then (re-)install linux (need internet connexion, wireless or no. Dont forget to start dhcpcd)
mount /dev/sdbZ /mnt # with /dev/sdbZ your keyboard's hdd root partition where linux will be installed
mkdir /mnt/boot
mount /dev/mmcblkpX /mnt/boot
mkdir /mnt/boot/efi
mount /dev/mmcblkpY /mnt/boot/efi
pacstrap /mnt/ base grub efibootmgr
genfstab -U -p /mnt >> /mnt/etc/fstab
- and install grub on partition
arch-chroot /mnt
grub-install --target=i386-efi --efi-directory=/boot/efi --bootloader-id=grub --recheck
- Edit /etc/grub.d/40_custom and add at the end :
if [ "${grub_platform}" == "efi" ]; then
menuentry "Microsoft Windows Vista/7/8/8.1 UEFI-GPT" {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --fs-uuid --set=root --hint-bios=hd0,gptY --hint-efi=hd0,gptY --hint-baremetal=ahci0,gptY [fs_uuid]
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
fi
with gptY, the Y from /dev/mmcblkpY above (the efi partition)
and [hints_string] is gave by the command
grub-probe --target=fs_uuid /boot/efi/EFI/Microsoft/Boot/bootmgfw.efi
- Apply grub config
grub-mkconfig -o /boot/grub/grub.cfg
Now I can boot to "Windows Boot Manager" or "grub" from bios. But I choosed to have grub by default and then he ask me what I want.
Virtualization
What works :
- host Win32, guest linux32
- host win32, guest win32
- host linux32, guest linux32
- host linux64, guest win
What doesn't work:
- host linux32, guest win32
Windows 8.1 guest : With QEMU and Virtualbox, same problem during installation (or boot when already installed) we got a
Your PC needs to restart.
Please hold down the power button.
Error Code: 0x0000000A
Parameters:
0xFFFFFFE6
0x0000001F
0x00000000
0x8192BFAB
After 3min virtualbox said that a critical error happend and tell us to watch the log. But it seem useless because the bug happend after 7 seconds and nothing show up after 7 seconds.
SD Card
http://www.jfwhome.com/2014/03/07/perfect-ubuntu-or-other-linux-on-the-asus-transformer-book-t100/ wrote:
The SD card reader works with newer kernels, but the sdhci module needs some configuration. Create a new file:
sudo nano /etc/modprobe.d/sdhci.conf
Then add the following:
options sdhci debug_quirks=0x8000
ctrl-o then ctrl-x to save and exit, then:
sudo mkinitcpio -p linux

However firefox doens't enable 3D acceleration by default, you have to force it. To check if it use it, go to about:support
And this mean that, it doesn't support it :
GPU Accelerated Windows 0/1 Basic
To force it :
- Got to about:config
- Set layers.acceleration.force-enabled
- Set layers.offmainthreadcomposition.enabled to true
And restart firefox. Now you should have
GPU Accelerated Windows 1/1 OpenGL (OMTC)
Warning : 3D acceleration can make firefox more buggy, so try to disable it if you have problems.

Random freezes
After some minutes (last time after ~40minutes) the system freeze. I don't know if it's only graphical or not. This freeze seem to happend when the cpu/gpu has a lot to do.
I've done a clean install with default kernel 4.0 in may 2015, and since that, I didn't have any freeze.
xhci_hcd bug at boot
When I enable XHCI in bios, sometime, I get that
xhci_hcd 0000:00:14.0: Error while assigning device slot ID
xhci_hcd 0000:00:14.0: Max number of devices this xHCI host supports is 32.
usb usb1-port3: couldn't allocate usb_device
The port change randomly and when it is port3, I loose the keybard and mouse and I have to make a hard reebot.
To "fix" this, I disabled XHCI (wich mean USB3) from the bios.
Still happen with kernel 4.0
Sound
With the work of  sid789. I manage to make sound work on Linux 4.0.

and you can load it by doing
alsactl -f asound.state restore
To change the values, you have to edit the field "value" of a control and reload the config file with the precedent command. I tried to comment it, but I didn't test any microphone, because I didn't need it currently. We are supposed to have 2 microphones : internal and via the jack. I think it's possible, but I don't have any jack microphone, so if you need it, try to change the different settings and tell me if you find something.
I don't think any GUI, will manage to make the sound control work (even in alsamixer, it's a big mess), because there is no convention followed.
To be continued

Answer 1

I had still freeze with uxa. I still don't have any freeze with disabled acceleration. But I also have the flickering tty, but it's not a big problem as this is still usable and I don't often use it.
Maybe when you tried, it was another bug that makes you freeze (with an older version of someting).. I don't know, I will write both solution on the topic.
I've done some search on the touchpad : If you look at the device output (cat /dev/hidraw2 for me), you will see that the device don't send anything when you have two finger that touch the device (so it's not possible to use it as dualtouch). I think it's just a starting data that is send from Asus Smart Gesture under windows that start the Multi touch mode. I've start a vritual machine and I gave it the touchpad usb device (wich is also the keyboard... Usb bus 1 address 3) and I started the driver. Under windows it worked well with multitouch. I killed the virtual machine and I got back my keyboard but not the touchpad. I watch at /dev/hidraw2 and the touchpad now give information with two and more fingers (also it give immediatly data and not after a small lag like normally). After a restart it was gone as expected. I watched the usb driver with usbmon and wireshark and I tried to reproduce UsbHid exchange between computer and device but it didn't work. I still don't know why but I will continue to search.
There is 3 sub device on the usb device mouse/keyboard. 0 is the keyboard, 1 the media key (fn keys except sound) from the keyboard, and 2 the touchpad. So if someone has time to works on media keys, I don't think this is verry difficult. (It's more difficult for the sound, win and sleep button on the screeen, because I didn't find any signals from it.
I will try to work on a aur package that give our kernel with fixes this summer. (And maybe also a pre-builded version).
