Linux如何檢視視訊記憶體

（以下內容由參看資料總結而來，若有不對，望指出）

用ctrl+alt+t開啟終端，輸入命令：lspci,得到如下（部分）：

00:1f.6 signal processing controller: intel corporation 5 series/3400 series chipset thermal subsystem (rev 06)

01:00.0 vga compatible controller: advanced micro devices, inc. [amd/ati] park [mobility radeon hd 5430/5450/5470]

01:00.1 audio device: advanced micro devices, inc. [amd/ati] cedar hdmi audio [radeon hd 5400/6300 series]

03:00.0 ethernet controller: qualcomm atheros ar242x / ar542x wireless network adapter (pci-express) (rev 01)

然後再輸入命令：lspci -vs 01:00.0 (注意和上哥命令查詢到的序號一致)，得到：

01:00.0 vga compatible controller: advanced micro devices, inc. [amd/ati] park [mobility radeon hd 5430/5450/5470] (prog-if 00 [vga controller])

subsystem: asustek computer inc. device 1bf2

flags: bus master, fast devsel, latency 0, irq 43

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:

kernel driver in use: radeon

256m即為視訊記憶體
