Hi,
After switch from -vga vmware to -vga std (use qemux86-64), start image
by "runqemu nographic",
Memory used by process Xorg raised a lot, for my image, from ~%7 to
~%34 (check by ps aux --sort -rss)
also check memory by command "systemctl status xserver-nodm", raised
from ~60M to ~120M.
with the high raise of memory usage of Xorg, when run oe-test on the
target, OOM is happened like:
[ 1038.221438]*Out of memory*: Killed process 180 (Xorg)
total-vm:335368kB, anon-rss:68824kB, file-rss:0kB, shmem-rss:140kB
Also test with poky distro, and image core-image-sato, also installed
procps.
1. "ps aux --sort -rss": Xorg from ~3.6% to ~ 17.4%
2. "systemctl status xserver-nodm": from ~65M to ~131M
Any idea about how to resolve this problem? do we really need unify all
boards to -vga=std? Thanks.
