From cfe549d1ba28396c44af94133d8c1d323e3c7086 Mon Sep 17 00:00:00 2001 From: Tilman Sauerbeck Date: Thu, 27 Sep 2007 22:36:52 +0200 Subject: [PATCH] EXA: Added back the maxPitchPixels initialization code. This doesn't add real value yet, but it will be useful once I add code that splits large render operations into smaller parts if necessary. --- exa/exa.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/exa/exa.c b/exa/exa.c index 8d70558e3..518a5f1e9 100644 --- a/exa/exa.c +++ b/exa/exa.c @@ -726,6 +726,21 @@ exaDriverInit (ScreenPtr pScreen, "non-NULL\n", pScreen->myNum); return FALSE; } + + /* If the driver doesn't set any max pitch values, we'll just assume + * that there's a limitation by pixels, and that it's the same as + * maxX. + * + * We want maxPitchPixels or maxPitchBytes to be set so we can check + * pixmaps against the max pitch in exaCreatePixmap() -- it matters + * whether a pixmap is rejected because of its pitch or + * because of its width. + */ + if (!pScreenInfo->maxPitchPixels && !pScreenInfo->maxPitchBytes) + { + pScreenInfo->maxPitchPixels = pScreenInfo->maxX; + } + #ifdef RENDER ps = GetPictureScreenIfSet(pScreen); #endif
