LG G3 VRAM size

很多人在說 LG G3 螢幕解析度很高很吃記憶體, 都只是隨便嘴巴講講沒什麼真實證據。

如果照這裡的方法來看的話

root@g3:/ # dd if=/dev/graphics/fb0  of=/dev/null bs=4096
7200+0 records in
7200+0 records out
29491200 bytes transferred in 0.695 secs (42433381 bytes/sec)

>>> 29491200 / 1440./ 2560. /4.
2.0

看起來數字是對的。
29491200 bytes ~ 30M 笑了 是真的有差很多嗎?

Nexus 4 是11796480 bytes ~ 12M

另外 dmesg 裡面沒有看到VRAM相關訊息

  1. 再說 Nexus 4 用 free 看記憶體 total 是1869628, LG G3 是 1885200, Linux 的 free 是會扣掉硬體裝置佔用的記憶體之後顯現的, 所以看得出來G3 沒有吃比較多記憶體。

    我自己看G3 應該是 swappiness 調得太高, 加上用 zram 當 swap 導致一直在 swap in, swap out 才 lag, 用 top 也可以看到 lag 的時候其實 kswapd0 在跑...

Generalisability of the findings is limited outcome of} small, purposive interview samples that had been 우리카지노 self-selecting and predominantly male, and information saturation may not have been achieved.
