PupSysInfo-2.8.6

[foxpup]

Hello bigpup
Thanks for the info.

The BIOS feature that controls all this is the DVMT Mode BIOS feature. It allows you to select the DVMT operating mode.

I looked into my efi firmware interface aka BIOS, but did not find anything like that there.
(But I did find an option Grapic Device. It can be [UMA only], enable integrated graphic controller only, or [Discrete] which enables both gc.
I tried that but did not bring up the nvidia in Pupsysinfo. But I do find some mentioning of nvidia as 3D controller in some places. )

Is there a place in Pupsysinfo to find the info about RAM on the Graphic Cards, like in windows? Or is there another tool to use?
I understand this is additional RAM to the proper RAM for the CPU.

Notice what your Pup-Sysinfo shows here:

VGA controller [0300]: Intel Corporation HD Graphics 520 [8086:1916] (rev 07)
• Kernel Driver: i915
• Memory Used by Driver: 1094.51 KB

This just says that very little memory, about 1M, is used for the driver, right? It is not even clear to me what kind of memory this is.

What you are seeing in Pup-Sysinfo is probably the pre-allocated Video RAM...

@foxpup, bigpup and other testers:

Currently, the Pup-Sysinfo video report does not probe the graphics chip directly, but uses the lspci utility to determine pre-allocated (prefetchable) video memory.

When parsing system information, Pup-Sysinfo calls only those tools common to all Pups but we could use the glxinfo utility to determine video memory. Beyond this, I'm not sure Pup-Sysinfo will further quantify the physical memory of the video card.

The revised function file below reports prefetchable video memory defined by lspci, and total video memory defined by glxinfo.

EDIT: file removed

Thanks

Put the new func file in Pup-Sysinfo 2.8.3

Well, that now gives more info about memory.

This is my graphics output.

VGA controller [0300]: Intel Corporation Atom Processor Z36xxx/Z37xxx Series Graphics & Display [8086:0f31] (rev 0e)
• Kernel Driver: i915
• Memory Used by Driver: 1216.00 KB
• Path: /lib/modules/4.19.12/kernel/drivers/gpu/drm/i915/i915.ko
• Description: Intel Graphics
• Video RAM: 1536M total, 256M prefetchable

This being integrated Intel Graphics, that uses system RAM.
That seems to show how much system RAM could be used as VRAM. (1536M)
I have 2GB of RAM in this computer.

After looking at this. That Memory Used by Driver: 1216.00 KB seems to be what the i915 driver uses to operate the driver.

That 256M prefetchable is this:

Prefetchable memory is memory which the CPU can request in advance as an optimization, before actual code operates on it. This happens because the CPU guesses it may be needed in the future or because the code contains explicit prefetch instructions. Then it prefetches those memory locations.

new func file in Pup-Sysinfo 2.8.3

To give you output for something other than Intel graphics.

This is from a Nvidia Geforce GTX 1070 card with its own 8GB of memory. It does not use system ram for graphics.
Using the Nvidia driver from Nvidia.

32M prefetchable

[foxpup]

This is the output now with the new func:

VGA controller [0300]: Intel Corporation HD Graphics 520 [8086:1916] (rev 07)
• Kernel Driver: i915
• Memory Used by Driver: 1094.51 KB

• Description: Intel Graphics
• Video RAM: 1536M total, 256M prefetchable

1536M for video RAM seems to me a lot more than the official 1G. What else could this include? It's "funny" this is exactly the same number as for the intel gc of bigpup.
(The normal RAM for CPU of this machine is 8G and video RAM is reported in windows to be 1G).

hi radky

with new func file correct video ram report here with an nvidia card apart from the weird 256mb bit at the end

Code: Select all

Video RAM: 4096 M total, 256M

• Video RAM: 8192 M total

do you want to swap cards?

@foxpup,

In a terminal, please run the following:

glxinfo | grep -Ei 'device|memory'

You will see something like the following for your Intel system.

Code: Select all

    Device: Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2) x86/MMX/SSE2
    Video memory: 1536MB
    Unified memory: yes

If I understand correctly, 'Unified memory' refers to Unified Memory Architecture (UMA), also know as Integrated Graphics or Shared Graphics, where system RAM provides shared memory for graphics rendering.

For graphics rendering, 1536MB Video Ram is a value commonly allocated by systems with Intel Integrated Graphics.

@666philb,

The second component of the Video RAM report refers to prefetchable video memory.

I'm not sure why the term 'prefetchable' is missing from your report. It should be included by default.

Prefetchable video memory refers to memory addresses reserved specifically for the transfer of video data, and this memory may be prefetched when the "CPU guesses it may be needed in the future or because the code contains explicit prefetch instructions".

[radky]

bigpup and 666philb,

It seems your NVIDIA PCs show two prefetchable addresses of video RAM.

@radky
Thank you for the explanation.
So the 1536M video RAM is actually part of the 8G RAM, and not additional?

[radky]

Hi radky,

Nvidia card, a relatively underpowered version compared to some.

Thanks perdido. Your report is much appreciated!

Hopefully, bigpup will also test the most recent func revision (or other users with video cards that allocate two prefetchable memory addresses).

[radky]

Thank you for the explanation.

Hi foxpup,

Yes, for your PC with integrated graphics, I think the 1536M represents shared memory allocated from the 8G system RAM.

Thanks for testing!

[bigpup]

bigpup,

To show total RAM and all prefetchable RAM on one single line, could you test the attached func file.

Thanks

Here is what I get with this new func file.

Pup-SysInfo-2.8.5
- Adjust CPU report: switch from dmidecode to direct parsing of /sys/devices for Min/Max Speed, and /proc/cpuinfo for assessment of Core Count and 64-bit capability
- Adjust Video report: call glxinfo to assess total video memory, and lspci to determine prefetchable video memory

On the same Optimus machine, I have tried PupSysInfo in Slacko64-6.3.2.
This is what it gives for display device:

Hi foxpup,

PupSysInfo-2.8.5 calls glxinfo to show video memory as part of the extended renderer information defined by GLX_MESA_query_renderer (if supported).

In legacy slacko64-6.3.2, glxinfo does not show extended renderer information, so total VRAM does not appear in the video report of PupSysInfo.
