https://bugzilla.kernel.org/show_bug.cgi?id=198511 --- Comment #23 from Barto (mister.freeman@xxxxxxxxxxx) --- so here is the output of "cat /sys/kernel/debug/dri/0/ttm_dma_page_pool" when no youtube video are played ( firefox is not running ), with kernel 4.15rc8 : pool refills pages freed inuse available name wc 1682 0 1344 5384 radeon 0000:01:00.0 wchuge 1130 4514 0 6 radeon 0000:01:00.0 cached 106272 424533 552 3 radeon 0000:01:00.0 cachedhuge 6 18 0 6 radeon 0000:01:00.0 and now with firefox running, youtube video hd@60 fps in full screen mode ( output given by my bash script running in background ) : pool refills pages freed inuse available name wc 1682 0 2089 4639 radeon 0000:01:00.0 wchuge 3012 12042 3 3 radeon 0000:01:00.0 cached 113562 453693 552 3 radeon 0000:01:00.0 cachedhuge 7 24 0 4 radeon 0000:01:00.0 I made another expirement : using a different web-browser : - If I use chromium 63.0.3239.132 ( a web browser based on chrome ) then there is no bug, playback is 100% fluid, no lags, it's perfect, - If I use opera 50.0 then there is a bug, like firefox 57, I get lags, the only difference is that I get a vsync problem ( tearing ) so it seems that your commit breaks something on applications like web-browsers if they use a precise technic for rendering streaming video ( related to memory management ? ), chromium seems to be the only web-browser which is not affected by your commit -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
