Hardware :: "lspci -v" / Determining Video Memory?
Dec 29, 2010
The box my video card came in says "1 GB DDR3" But when I run "lspci -v" I get this:
Code:
01:00.0 VGA compatible controller: nVidia Corporation G92 [GeForce GTS 250] (rev a2) (prog-if 00 [VGA controller])
Subsystem: eVga.com. Corp. Device 1145
Flags: bus master, fast devsel, latency 0, IRQ 18
[code]....
EDIT:I read this somewhere:"The amount of memory lspci shows is only the amount of memory mapped directly to the PCI bus. So, both your CPU and GPU can "see" 256 MB, but only the GPU can access the rest directly."What I'm wondering is, I'm setting up wine in "regedit". I'm adding this string:
"VideoMemorySize"="xxx" to this key: HKEY_CURRENT_USERSoftwareWineDirect3D So what do I put? 1024 or 256?

I am running ubuntu 10.04 with the fglrx driver installed with apt-get. I have an ATI Radeon HD AGP with 512MB of video ram. My bios window size is 64MB. The Xorg.0.log file shows that 512MB is recognized. I also tried checking the /proc/mtrr file and it shows two values one I believe is my ram size which looks to be correct at 1.5GB the other is 512MB which I think is my video ram size, but when I do an lspci -v the video ram size shows 256MB. I am trying to run Doom 3 and it only allows me to use 256MB of memory.

I have have to write a video device driver, but rendering will happening in memory, not on a physical card. I already wrote a simple driver stripping out hardware piece code from an existent vodoo driver. I an install it, uninstall it but i dont know how to map it to a file /dev/mydevice_video
Is there a field in fb_info or fb_vscreenifo where the device name has to be passed before calling register_framebuffer.

I just got a Sony DCR-DVD108. It uses a mini dvd and a memory stick pro duo. It was a gift, and it's the first time through the rodeo for me using this set up. I can get the card recognized when I plug it in using a card reader. I want to record video, and that's where I run into problems. When I insert it, I get something saying that I have still photos, and Shotwell is the default photo software. That would be OK if I had still photos, but like I said, I'm going for video with this set up. I have VLC, but when I tell VLC to "open capture device" under "Media" it gives me a dialog box with (I think) Linux 2 as the capture method (this is going to get a little fuzzy as I have no idea what it's looking for here) and a couple of blanks that need filled in. I may be going about this bass-ackwards, in fact I probably am, but like I said, this is the first time I've messed with a memory stick pro duo. I guess since it's Sony they want me to go out and buy a Play Station to get this to work. I don't think I want to go there. I might be barking up the wrong forest with VLC, but Wikipedia says it will play it.

I'm trying to increase my framerate on World of Warcraft, and I'm not sure if this will help but it should in theory. I'm not even sure if I'm right in my assumption that it's currently non-optimal. nvidia-settings reports the full 1024MB of onboard video memory from my 420GT, but lspci reports three separate figures which don't even add up to 256MB:
[Code]....
Now, I don't know which to trust, is all the video memory being detected or just the pittance that lspci reports? To my mind, more graphics memory means you can store more graphical code and data closer to the gpu resulting in faster framerates, right?

I recently bought 1GB video card of 'xfx radeon hd 5450'. It came with cd for drivers of windows.
I installed fglrx. Still in ubuntu 10.10 (lucid) I ran: lspci -v | grep -i prefetchable
which shows 256M which is video memory of my ASUS motherboard.

I have two NIC cards installed, they both go to seperate networks. Occassionally I am not able to establish a connection via eth1. When looking at tcpdump traces I see that Linux is using eth0 hardware port and putting eth1's IP address in the packet to reply to the connection request. When the connections work its when Linux uses eth1's port.

Using a Linux program to fix my TiVo. Program is burned to a bootable CD, which loads fine. I get asked what the drives are (CD and Hard Disk) with abbreviations like hda, sda, etc. I was able to determine the Hard Drive as /dev/sda, by using <Shift>-PgUp/PgDn, but could not find what the CD drive was.

I have and embedded system which apparently, due to space considerations, is missing lots of normal commands. I can get the following information by "cat /proc/version":
Linux version 2.4.19-uc0 (...) (gcc version 2.95.3 20010315 (release)(ColdFire patches - 20010318 from http://fiddes.net/coldfire/)(-msep-data patches)) #461 Tue May 24 12:06:06 PDT 2011
At issue is the fact that, after some time, the system stops responding to the Network (e.g., you can ping it, then some time later you can't). We suspect that some sort of network monitor is accessing the device and causing the trouble, but don't know for sure.
What I would like to do is log some sort of useful network status information and/or be able to reset the network if I can figure out there is an issue from within the device.
I thought I had it all working using "/etc/init.d/network restart" but I've come to find out that the command is not recognised in this system. I also can't issue a "top" command to see what services are running. I can Telnet in, so I can try commands and see if they work.
Have any of you worked with such an abbr. system and if so, what might be around that I'm unaware of to help determine network status?

This questions pertains mainly to building a brand new GNU toolchain on one machine for deployment on fs of another machine that has no toolchain installed. I understand the machine on which GNU toolchain is going to be built as the 'build' machine. I understand the machine on which GNU toolchain is going to be deployed as the 'host' machine. I understand the machine on which the code generated by the new GNU toolchain is going to be run as the 'target' machine.
Q1.) Is there a fixed 'rule', 'matrix' or 'table' somewhere which tells me exactly which versions of 'binutils' and 'libc' are required by a particular version of GCC? I.e. something along the lines of:
- gcc ver.'k' can be built using gcc ver.'m'(or later) with binutils ver.'i' and libc ver. 'j'
- gcc ver.'k' will operate with binutils ver.'t' and libc ver.'r'(or later)
Is there some 'rule of thumb' / 'heuristics' giving me the above version requirements for the building and operating GCC, or is this information somehow implied or derived systematically. Where can I find more about the above?
Q2) I assume that the libraries have no dependencies on any underlying software other than the system calls provided by the kernel. Furthermore it appears that the libraries are not too sensitive about the kernel version they run on (I found this out from experience). Therefore I could build the libraries on some build machine and place them on the bare naked newly set up host file system without regard to any other prerequisite SW components?
Q3) During operation, do GCC and its various components place system calls directly to the kernel or via library calls (or both)? In other words I am trying to understand conceptually if GCC requires 'Glibc' for its own operation or not?
Q4) During operation, do the 'binutils' components place system calls directly to the kernel or via library calls (or both)? In other words I am trying to understand conceptually if the 'binutils' require 'Glibc' for their operation or not? ( Of course it is clear to me that when GCC is operating it will need libraries and headers to resolve object references in the target code it produces, but that would be a >different< question).

I am trying to scroll text from a text file across a wx.panel. This is the code so far:
Code:
def scrolling(self, text, rate):
def scroll(): charList = []
dc = wx.ClientDC(self.panel_1)
open_text = open(text, "rb")
my_text = open_text.read()
charList.append(my_text) open_text.close()
x,y = self.panel_1.GetClientSizeTuple()
while 1: for z in charList: for r in range(2000):
dc.DrawText(z,x-r,0) time.sleep(rate) dc.Clear()
net3 = threading.Thread(target=scroll)
net3.setDaemon(1) net3.start()
It scrolls but I am guessing where the range is (2000). I need to be able to determine the total number of pixels that the text in the file is. Is there a python way to determine this?

I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.
Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data

I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:
> uname -rmi
2.6.18-53.el5 x86_64 x86_64
> grep eth0 /etc/modprobe.conf

I want to take the output from lspci | grep VGA and grab the BusID's of each video card installed on a server. I then want to take these BusID's and convert them to decimal (Which I can do fine). I then want to take these numbers and have them as the input of a few perl search and replace commands for xorg.conf. I'm mostly stuck on trying to get each BusID that is outputted from lspci and using them as inputs (or variables).

I ran the 11.04 upgrade. At the end, it reported a failure, implied a recovery would occur and the upgrade then finished. The recovery was supposed to have run sudo dpkg --configure -a. That does not appear to have happened. I am concerned that a reboot will render my system inoperative.Has anyone else experienced a similar issue or have any suggestions? What information should I provide. report.

Ubuntu 10.04 fresh install 64bit. Wireless was working in 9.10, now does not even show up in restricted drivers. Installed bcwl-kernel-source, and b43-fwcutter. ifconfig, iwconfig only show eth0 and lo - no wlan
Other restricted drivers show up - using NVIDIA driver with Compiz running better than ever on 2 screens
Here is the output from the collectNWData script found at [url]
I do notice that in the firmware section that both b43 and b43legacy are listed. Somewhere I reads that I should be using b43 - not the legacy version. Should it be blacklisted?
