Try to set virtual height <= 2048. Current intel driver will disable accel if virtualY's larger than 2048, which I think a little overkill. As hw at least supports 2D blit larger than that, and disable smaller size pixmap acceleration totally. I don't know much of why it is, Eric? I think We'd just fix exa to handle driver's limits and alignement correctly, and let it pass down those can be done in hw. I have pushed pitch check patch in intel driver on 2.3-branch, although we might fix left issue later, but just check them for safe now. > diff --git a/exa/exa.c b/exa/exa.c > index 81dc3e2..5014c0f 100644 > --- a/exa/exa.c > +++ b/exa/exa.c > @@ -385,6 +389,9 @@ exaModifyPixmapHeader(PixmapPtr pPixmap, int width, int height, int depth, > > if (pExaPixmap) { > pExaPixmap->sys_ptr = pPixData; > + pExaPixmap->sys_pitch = devKind; > + We'd better check (devKind > 0). > + exaSetFbPitch(pExaScr, pExaPixmap, width, height, bitsPerPixel); > > exaSetAccelBlock(pExaScr, pExaPixmap, > width, height, bitsPerPixel); _______________________________________________ xorg mailing list xorg@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/xorg
