how to install driver for intel extreme graphics 2 - linux-device-driver

I installed Linux on an Intel Panel PC. Jockey cannot detect any drivers. I do not know how to install my graphics driver first so that I am be able to install touch screen.
Here's some info from dmesg:
dmesg | grep vga

As I searched more, I think the graphics driver is installed by default, but I have no idea how I can check it availability in my system.
sound driver is installed correctly.

You can check state of driver in kernel, if it implemented as "kernel object" = .ko file with command "lsmod". If it wasn't loaded in kernel, you can load it manually with command "insmod mod_name_with_path".
You can also set automatic load your driver at system startup with command "echo mod_name_with_path >/proc/sys/kernel/modprobe".
There is useful info about lkm (kernel objects): http://www.tldp.org/HOWTO/html_single/Module-HOWTO/

How to setup SR-IOV with Samsung PM1733/1735 NVMe SSD

The Samsung PM1733/1735 NVMe SSDs declare the SR-IOV supports. And I hope to set up a NVMe SR-IOV environment with a PM1735 SSD. The dev description of my SSD is /dev/nvme1.
However, I tried with commands like
echo 4 > /sys/class/nvme/nvme1/device/sriov_numvfs.
The dmesg information contains that

Are the VFs correctly created?
And another question is how can I bind the namespaces with the VFs. I used nvme-cli to create namespaces from the /dev/nvme, but how can I bind these namespaces with VFs?
Allocate VQ and VI using nvme cli command nvme virt-mgmt and enable that controller and export that vf to vm.
example commands
nvme list-secondary /dev/nvme1n1 --> output of list of all secondary controllers
nvme virt-mgmt /dev/nvme1n1 -c 1 -r 0 -n 2 --> allocate 2 VQs for secondary controller 1
nvme virt-mgmt /dev/nvme1n1 -c 1 -r 1 -n 2 --> allocate 2 VIs for secondary controller 1
nvme virt-mgmt /dev/nvme1n1 -c -a 9 --> enable secondary controller 1
nvme list-secondary /dev/nvme1n1 --> check first entry is updated and now shows as online.
Now export this vf to vm.
You might need to check nvme spec 1.4 (page 320, section 8.5 Virtualization Enhancements). I guess you also need to configure VQ and VI).
vitaliy-kachmar
You will still see in host as "Initialization Aborted" for VFs.
After VI and VQ and online variables are set, now you can export the VF to a Guest OS/hypervisor. In Guest OS, you can check that nvme block device is generated, as soon as OS startup completed.
First create nvme namespaces using nvme create command and then attach using nvme attach-ns to the controller, create single or multi-namespaces, then create VF and try export.
To export VF to VM.
Install virt-manager and install Guest OS (centos or unbuntu etc..) in virt-manager, i used Ubuntu. you can also refer - https://help.ubuntu.com/community/KVM/VirtManager
Now, you have VFs and VMs.
To export, select any Guest OS
select open and select add-hardware option in new window and select PCI and add one of VF 0000:86:00.1/2/3/4 device
Run guest OS.
In lsblk you will find one char device /dev/nvme0 and block devices /dev/nvme0n1 and now you can run fio on the block device

ath9k_htc (Atheros) TL-WN722N WiFi dongle on Angstrom

I am trying to interface the TL-WN722N to a Altera Cyclone SoC. I have taken the following approach:
Downloaded the open firmware ath9k_htc and try integrating it to my linux kernel image to be loaded.
a. https://wiki.debian.org/ath9k_htc/open_firmware: The steps here mention to build the toolchain and the firmware and then place it in /lib/firmware.
b. Built the linux kernel using the steps mentioned here : https://rocketboards.org/foswiki/Documentation/GSRDCompilingLinux
The firmware obtained in step a. was placed into /linux-socfpga/firmware , since there was no firmware folder in directory /lib/.
c. The image created was flashed and the wifi dongle was plugged in.
2.Here is a dmesg output for the cyclone board :

The linux is able to identify the Atheros usb device. However the driver module is not loaded. I have verified this using lsmod and it returns nothing. The commands ifconfig and ip a also returns no wireless connection.
Also when I see the path /lib/modules/.../kernel/drivers/net I observe only 2 modules ethernet and mdio.ko
Kernel version : 4.1.33-ltsi-altera
Does that mean that my driver is missing in the image? What could be the possible reasons for this issue? Does anyone have any other solution to this issue?
Edit:
I could find the linux drivers in /sys/bus/usb/drivers/ath9k_htc and the corresponding modules in /sys/module/ath9k_htc
So basically, the modules are configured static.
Now when I boot up the system, I find an error saying that the requested firmware is not found.
I have already placed the required firmware(htc_9271-1.4.0.fw & htc_9271.fw) in /lib/firmware/ath9k_htc
Here is the error :
[ 2.002205] usb 1-1: new high-speed USB device number 2 using dwc2

I have also followed the steps mentioned here :
https://unix.stackexchange.com/questions/21903/custom-kernel-fails-to-load-firmware-when-module-built-in
which explains how to provide configuration for the path for loading the firmware.
A quick grep for /proc/config.gz reveals this:
$zcat /proc/config.gz | grep CONFIG_ATH
CONFIG_ATH_COMMON=y
#CONFIG_ATH_DEBUG is not set
#CONFIG_ATH5K is not set
#CONFIG_ATH5K_PCI is not set

#CONFIG_EXTCON is not set
zcat /proc/config.gz | grep CONFIG_FIRMW
CONFIG_FIRMWARE_IN_KERNEL=y
# CONFIG_FIRMWARE_MEMMAP is not set
Is there any other way to notify the kernel to load the firmware? I think I might be missing out some configuration.
Edit 2 :
I resolved the issue of firmware load failure by enabling the option Fallback user-help invocation for firmware loading. Now the device is initialised, but the driver seems to not support the device. Here is the dmesg log :
[ 14.568484] usb 1-1: ath9k_htc: Transferred FW: ath9k_htc/htc_9271-1.4.0.fw, size: 51008

[ 15.866512] ath: phy0: Unable to initialize hardware; initialization status: -95
[ 15.873973] ath9k_htc: Failed to initialize the device
A quick research on the device, I found that the official website of TP-Link states that the linux drivers are available for version 2, and not for version 1. My device is a version 1 device and I think because of this the driver does not support.

RPi3 with SenseHat and Yocto

I am currently working with building a Yocto Image for the RPi3 with the SenseHat installed.
The Yocto image consist of the following layers:
meta
meta-poky
meta-oe
meta-networking
meta-python
meta-raspberrypi
meta-java
an application-specific layer.
The application-specific layer is mainly tasked with loading the following kernel-modules:
i2c-dev
fb_sys_fops
syscopyarea
sysfillrect
sysimgblt
rpisense_core
rpisense_js
rpisense_fb
It also contains openssh, psplash, gcc, make, libiio, rtimulib and some other misc. packages.
My image boots nicely without the SenseHat mounted, but the boot-process stops before reaching the UART shell when it is mounted. It stays frozen until the system is reset by the watchdog.
Following is the last part of the UART output before the system freezes.

I shoould note that I have soldered three wires onto the UART pins:
RPi3 UART pins http://www.embeddedforu.com/wp-content/uploads/2015/06/Raspberry-pi-UART-connections_thumb.png
When the system is frozen, I can still ping the device, but SSH does not work.
Any idea what might be causing this behavior?
It turned out that the problem lay within the yocto local.conf-file. The following line was set:
ENABLE_I2C = "1"
This created a second i2c-driver, which lead to one of the crashing on boot.
For any googlers out there: This flag does not need to be set. Instead make sure that the i2c-dev kernel driver is loaded at boot.
I never used the bluetooth, but it seems the system doesn't freeze, you just lose UART data when Bluetooth connects.
From here:
On the rpi3, it is normal since the BCM2837 on the Raspberry Pi3 has 2 UARTs (as did its predecessors), however to support the Bluetooth functionality the fully featured PL011 UART was moved from the header pins to the Bluetooth chip and the mini UART made available on header pins 8 & 10.
This has a number of consequences for users of the serial interface.
The /dev/ttyAMA0 previously used to access the UART now connects to Bluetooth.
I would advise you to try again having in config.txt
dtoverlay=pi3-disable-bt
enable_uart=1
And if you really need bluetooth, use
dtoverlay=pi3-miniuart-bt
And for the ssh, add "openssh" in your image recipe, and dependencies to connect like wpa-supplicant (don't forget to configure it)

Can't register rteth0 for FEC Ethernet card on SabreLite iMX6Q

I'm a new user on RTnet and try to make Rtnet work on Freescale Sabre Lite iMX6Q board. But I got an issue, RTnet can't use rt_fec.ko module driver to register rt_eth0 even though non real time driver is disable.
I'm using:
Linux kernel 3.0.43 download from Xenomai git://git.xenomai.org/ipipe-gch.git/?h=ipipe-3.0-imx6q
Xenomai 2.6 download from git.xenomai.org/xenomai-2.6.git/
RTnet 0.9.13 download from rtnet.org/download.html
Please see my kernel configuration and boot log in attached link.
Xenomai is loaded:
"*I-pipe: Domain Xenomai registered.
Xenomai: hal/arm started.
Xenomai: scheduling class idle registered.
Xenomai: scheduling class rt registered.
Xenomai: real-time nucleus v2.6.3 (Lies and Truths) loaded.
Xenomai: debug mode enabled.
Xenomai: starting native API services.
Xenomai: starting POSIX services.
Xenomai: starting RTDM services.* "
And FEC ethernet driver (non real-time driver) is loaded when kernel is booting
*"FEC Ethernet Driver
fec_enet_mii_bus: probed "*
Xenomai is built following install guideline for ARM platform from Xenomai:
http://xenomai.org/installing-xenomai-2-x/
RTnet is built by below command, because SABRE Lite use FEC ethernet card with Micrel KSZ9021 Gigabit chip so I put "--enable-fec" in configure command to build real-time driver for FEC ethernet card:
"./configure --host=armv7l-timesys-linux-gnueabi --with-rtext-config=/home/sonnguyen/rtnet-xenomai-rootfs/usr/xenomai/bin/xeno-config --with-linux=/home/sonnguyen/build/rtnet-xenomai-ipipe-imx6q --enable-rtcfg-dbg --enable-rtwlan --enable-net-routing --enable-router --enable-nomac --enable-rtcap --enable-proxy --enable-checks --enable-fec "
Then
"make DESTDIR=/home/sonnguyen/rtnet-xenomai-rootfs install"
I also changed RT_DRIVER from default value to "rt_fec" in rtnet.conf.
After kernel is booted, I ran "./rtnet start" and got this:
"RTnet: initialising real-time networking
RT FEC Ethernet Driver
./rtnet: line 385: can't create /sys/bus/pci/drivers/rt_fec/bind: nonexistent directory

ls /sys/bus/

event_source i2c mmc scsi serio usb "
No pci directory under /sys/bus/. Then I thought because the script can't find the ethernet physical bus, it can't register rteth0.
Then I looked into rtnet script and did some minor change. In the script it requires physical ethernet device ID (mentioned in REBIND_RT_NICS), so I tried to find out what it is and got this when make eth0 up with non real-time driver:
"eth0: Freescale FEC PHY driver [Micrel KSZ9021 Gigabit PHY] (mii_bus:phy_addr=1:06, irq=-1)
PHY: 1:06 - Link is Up - 1000/Full "
I think 1:06 is my physical bus ID, then I change the code in rtnet from:
for dev in $REBIND_RT_NICS; do
if [ -d /sys/bus/pci/devices/$dev/driver ]; then
echo $dev > /sys/bus/pci/devices/$dev/driver/unbind
fi
echo $dev > /sys/bus/pci/drivers/$RT_DRIVER/bind
done
To
echo 1:06 > /sys/bus/mdio_bus/drivers/Micrel\ KSZ9021\ Gigabit\ PHY/unbind
echo 1:06 > /sys/bus/platform/drivers/rt_fec/bind
And I tried again with "./rtnet start", this time I got this:

NV-GLX missing extension in OS X Lion

I connect to a remote linux machine using "ssh -X machine", and then I run a graphical application, so its window is displayed on my local OS X Lion machine using X Window. I get the error
"Xlib: extension "NV-GLX" missing on display "localhost:11.0"."
The application moves very slow. Is it any way to use NV-GLX on OS X or to cimcurvent this problem?
I've encountered similar problem trying to connect from a laptop with AMD graphical card to a linux server with NVIDIA card and drivers installed.
If you have root access to your remote linux machine you could try to restart X server with default libglx.so, not the one from NVIDIA driver package. Appears that NVIDIA installer doesn't support partial installation (only driver, no GLX lib), so one needs to remove NVIDIA libglx.so from xorg modules path, but leave nvidia_drv.so. On Debian you could do
