is it possible to have opengl|Es 3.0 or above with these system configuration:
Dell Inspiron 1464
processor - Intel® Core™ i3 CPU M 350 # 2.27GHz × 4
graphics - Intel® Ironlake Mobile
os Type - 64 bit
when i run glxinfo i have output as:
GLX version: 1.4
OpenGL version string: 2.1 Mesa 10.3.2
OpenGL shading language version string: 1.20
i did also use launchpad to get opengl 3.0
sudo add-apt-repository ppa:oibaf/graphics-drivers
but got this response from glxinfo:
GLX version: 1.4
OpenGL version string: 2.1 Mesa 10.3.2
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 10.3.2
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16
i do find on some places that intel ironlake mobile graphics do not support opengl 3.0 fully, as i have also intall all the intel graphics drives in my other OS windows7 to get opengl 3.0 but it still says 2.1 only, while it showing some of the features of 3.0 and 3.1 but not fully.
https://software.intel.com/en-us/forums/topic/281262
the image in this link shows the exact case of mine in Windows 7.(i could not able to post the image but you'll surely get the proper picture of the problem from the link's image)
Mesa utils also says that it supports opengl 3.0 from 8.0 but totally depends on the system graphical support.
i needs opengl 3.0 very badly, can some one please give any idea regarding this.
i did see
http://stackoverflow.com/questions/14123895/opengl-glsl-3-3-on-an-hd-graphics-4000-under-ubuntu-12-04
http://stackoverflow.com/questions/21565680/how-to-enable-opengl-3-3-using-mesa-10-1-on-ubuntu
and many other links like these but could not get any solution.
i have already tried AMD catalyst drivers (15.7, 14.12, 12.1, 13.1)but not supported i.e they were all installed fglrx but when i ran aticonfig or amdconfig they says no supported adapters, and they are giving same opengl 2.1 response.

Well i have tried these unsuccessful options..
installs almost all intel and AMD drives.
upgrade to ubuntu 14.10 and install intel driver installation deb as it
supports only ubuntu 14.10 and a fedora version.
installs propriatery drivers(iobaf) many times , but as i says 15.04 i have
also upgrade to ubuntu 15.04 and tried it again, no success.
My processor is ironalake Arrandale, 2.26 GHz Core i3 350 M.
Intel HD Graphics.

http://ark.intel.com/products/43529/Intel-Core-i3-350M-Processor-3M-Cache-2_26-GHz
I don't think that it's possible to have Opengl 3.0 with these configuration, either in windows or in linux.
If someone finds any solution regarding that then kindly share it here, it would be very helpful.
for now i am using ubuntu 15.04 as it goes good with my AndroidStudio with NDk support, and i am using my Android Device to have opengl 3.0 support as my system can't give it to Genymotion which i wanted to run for Opengl 3.0 support.

After thorough debugging, I found out that current kernel on nvida tegra tk1 doesn't have firewire1394 driver. So, I need to know which kernel I can recompile to use firewire1394 driver.
The stock Linux kernel 3.10.40 does not have a firewire1394 driver. So, I added a firewire1394 driver.
The "Grinch" kernel adds 1394 support. The Grinch kernel is available from: https://devtalk.nvidia.com/default/topic/823132/embedded-systems/-customkernel-the-grinch-21-3-4-for-jetson-tk1-developed/
I followed the instructions and finally I have the firewire1394 driver installed and loaded.
To install CUDA and OpenCV4Tegra, one can then use application manager and then unchecked the linux and flushed option.
I am hoping that you're able to help me I am trying to understand how use the /proc file system or profile settings. I am trying to write a script which pulls the temp of the CPU and a list of peripherals attached to a SUSE device. This would be using native functionality rather than a tool. Is there a path of sorts to the variable for temp of the CPU and a list of attached devices?
Hopefully it makes sense.

To get temp use "sensors":

or look at the /sys/class/hwmon/
$ cd /sys/class/hwmon/hwmon0/device/
{ cat temp3_label; cat temp3_input; }

Objective
I'm trying to programmatically find out on which physical slot a particular PCIe device is connected. The premise is that I have the PCI-ID of a card that is surely occupying a slot, and the solution would be finding out which one.
Note that I'm only interested in working on the PCI Express bus, although the device identification/enumeration process I think is the same as the old PCI.
Attempt
The SMBIOS contains information about the motherboard slots available. It is possible to examine this information from the linux command line:
$ sudo dmidecode -t slot
# dmidecode 2.11
SMBIOS 2.7 present.
Handle 0x003A, DMI type 9, 17 bytes
System Slot Information
Designation: PCIEX16_1
Type: x16 PCI Express x16
Current Usage: In Use
Length: Short
ID: 1
Characteristics:
3.3 V is provided
Opening is shared
PME signal is supported
Bus Address: 0000:03:02.0
Handle 0x003B, DMI type 9, 17 bytes
System Slot Information
Designation: PCIEX16_2
Type: x8 PCI Express x8
Current Usage: In Use
Length: Short
ID: 2
Characteristics:
3.3 V is provided
Opening is shared
PME signal is supported
Bus Address: 0000:04:02.2
Handle 0x003C, DMI type 9, 17 bytes
System Slot Information
Designation: PCIEX16_3
Type: x16 PCI Express x16
Current Usage: In Use
Length: Short
ID: 3
Characteristics:
3.3 V is provided
Opening is shared
PME signal is supported
Bus Address: 0000:05:03.0
However, I can't find any device in the PCI bus (lspci) that has a PCI ID of 0000:03:02.0, 0000:04:02.2 or 0000:05:03.0. What I know by manual inspection is the following:
Card 0000:03:00.0 is in the first slot. The PCI bridge appears to be 0000:00:02.0
Card 0000:04:00.0 is in the second slot. The PCI bridge appears to be 0000:00:02.2
Card 0000:05:00.0 is in the third slot. The PCI bridge appears to be 0000:00:03.0
So a pattern emerges here. From the SMBIOS structure, the bus number is the one given to the card that is plugged in but the device/function numbers are the same as the corresponding PCI bridge.
Is this pattern just a coincidence in my motherboard or there is a rationale behind? It is an Asus motherboard, with an AMI BIOS. I've read that some BIOSes do not provide accurate information about their slots so I would like to know how much generality I can achieve.
Any hint or pointer to reference documentation is also greatly appreciated.

I'm trying to find the base (memory) address of a parallel port I have connected to my laptop via a PCI express card. Running lspci -v shows that my computer recognizes the parallel port and gives the I/O ports (1000 and 1008) but not the memory address (other entries have both ports and memory locations…this card is the only entry without a memory address). Also, when I look in /proc/ioports I get the same ports given in lspci. However, when I try to use either of those addresses in the program I'm running (EMC2 to control stepper motors), it does not find a parallel port at that address.
What would be really great is if there were an analogue to the Windows Device Manager -> Ports -> Resources. Is there any way to do this in Ubuntu? Is there a standard memory location for PCIe devices?
Edit:

Try cat /proc/ioports | grep parport to filter the output of ioports.
Quick answer: there is no memory location for the parallel port. Parallel ports only ever have IO ports allocated to them. This is the way parallel port interfaces have worked for decades, and nobody has felt the need to make an incompatible memory mapped interface that would need special drivers.
Now I must ask, why are you intent on finding the port's memory location? What do you want to do with it?
Is there a simple way to detect nic and associated ports on systems loaded with linux.
From my study on this, i found lshw -C network would help me to some extent, by giving details on ports and interfaces.
But i didn't get clear differentiation done with nic and associated ports.
Say if i have 2 nic cards with one 4 ports and other nic with 2 ports, how to i detect this information using lshw or any way!!.
lshw -C network ( only portion of the information pasted here)
Using lshw -C network, we can use the serial number for example:
*-network:0
description: Ethernet interface
product: 82575EB Gigabit Network Connection
vendor: Intel Corporation
physical id: 0
bus info: pci#0000:01:00.0
logical name: eth0
version: 02
serial: 00:14:4f:e7:40:e0
*-network:1
description: Ethernet interface
product: 82575EB Gigabit Network Connection
vendor: Intel Corporation
physical id: 0.1
bus info: pci#0000:01:00.1
logical name: eth1
version: 02
serial: 00:14:4f:e7:40:e1
*-network:0 DISABLED
description: Ethernet interface
product: 82571EB Gigabit Ethernet Controller (Copper)
vendor: Intel Corporation
physical id: 0
bus info: pci#0000:2b:00.0
logical name: eth6
version: 06
serial: 00:15:17:be:e6:75
*-network:1 DISABLED

product: 82571EB Gigabit Ethernet Controller (Copper)
vendor: Intel Corporation
physical id: 0.1
bus info: pci#0000:2b:00.1
logical name: eth4
version: 06
serial: 00:15:17:be:e6:74
serial number kind of helps, the first five tuples help me to distinguish the nics and the last tuple in the serial number seems to be in sequence when in comes to different ports on given nic.

I'm not entirely sure what information you want to know. I'm guessing you want to know which ethernet interfaces are on the same board. One quick way to detect is via the sysfs directory which contains information about devices and drivers. This information can also be correlated to lspci.
Example:
find /sys/devices/ -type d | grep eth
Which outputs data on my system in the format of:
/sys/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/net/eth0
Where pci0000:00 is the bus, and the last number is the card (0000:02:00.0).
Then if I run lspci I can look up the card identifier to get more information
lspci | grep 02:00
Nets me:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02)
On your system, you should have multiple eth* mapped to each card. This should tell you the mapping of which eth to which card and more information about each specific card.
