[SOLVED] Invalid GPU memory capacity

Hello.

I have MSI GE600 notebook with 1024 GDDR VRAM (source http://www.msi.com/product/nb/GE600.htm … ification). Unfortunately Arch detects only 256mb:

[piotrek@piotrek ~]$ sudo lspci -v -s 01:00.0
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Madison [Mobility Radeon HD 5000 Series] (prog-if 00 [VGA controller])
    Subsystem: Micro-Star International Co., Ltd. Device 1004
    Flags: bus master, fast devsel, latency 0, IRQ 46
    Memory at e0000000 (64-bit, prefetchable) [size=256M]
    Memory at f0020000 (64-bit, non-prefetchable) [size=128K]
    I/O ports at d000 [size=256]
    Expansion ROM at f0000000 [disabled] [size=128K]
    Capabilities: [50] Power Management version 3
    Capabilities: [58] Express Legacy Endpoint, MSI 00
    Capabilities: [a0] MSI: Enable+ Count=1/1 Maskable- 64bit+
    Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?>
    Capabilities: [150] Advanced Error Reporting
    Kernel driver in use: radeon

Is there anything I can do so Arch would detect 1024mb instead of 256mb? Thanks in advance for Your kind help.

That lspci only sees 256mb is irrelevant, the component that matters - the graphics driver - *does* see 1024mb.

Re: [SOLVED] Invalid GPU memory capacity

This lspci output only means that your GPU has 256MB + 128KB of some memory or registers mapped into CPU physical address space. Running dmesg |grep radeon will likely reveal what the radeon driver thinks about VRAM of this GPU.
