The commit "sna: Flush blt copies if no operations pending" (8751c0f5a) introduced (or exacerbated) a memory leak of vast proportions. It's so huge that within less than two minutes of watching an ordinary YouTube video the X server (git, mesa also git) will exhaust all of my 16GB RAM. With it reverted, the server remains at 0.3-0.6% again.
Odd, very, very odd. What's the exact procedure for reproducing? (Watching youtube is a pretty common activity. So what is special about your machine and sequence?)
No idea. All I have to do for it to occur is boot, start Chromium, and watch a video. (Though that's only the fastest way, it will gradually happen without video playback — or Chromium — as well.) Machine is a Haswell 4770, no dedicated video card.
Could it be the "kgem_bo_destroy(kgem, op->src.bo);" in sna_blt.c's "convert_done" that gets skipped when the return in the newly introduced if is hit? Bit more info: Arch Linux x64 with xmonad, xorg dependencies as found in their repos.
I thought I'd chime in with - me too - I'm on a Gentoo system however Could it have anything to do with using gcc 4.8.1? I've temporarily switched back to UXA - watching youtube videos would consume ~1% of memory per second and would take out X within 2 minutes This was with Chromium 29.0.1547.0 & Pepper Flash 11.8.800.96 Would you like me to retest with other video players / regular flash?
