Hello, I've a use-case where the client uploads 32x32 A8 images to an 256x256x8 pixmap which is later used as mask in a composition operation. The test-case is able to render with 40fps on xserver-1.3/intel-2.1.1 however with the latest GIT of both I only get ~10-15fps. Unfourtunatly I've not been able to create a stand-alone testcase which triggers this problem :-/
Using sysprof I can see a lot of time is spent moving data arround, very strange is that PutImage seems to cause a readback: ProcPutImage->ExaCheckPutImage->exaPrepareAccessReg->exaDoMigration->exaDoMoveOutPixmap->exaCopyDirty->exaWaitSync->I830EXASync In Composite I see the re-uploading again. Any idea why ProcPutImage could to fallback (there's plenty of free vram)? Are there tools / settings which could help me to identify the problem? Thank you in advance, Clemens _______________________________________________ xorg mailing list xorg@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/xorg
