From 40427025916e003cfd380c2e30df78ad2bc8fe10 Mon Sep 17 00:00:00 2001 From: Anuj Phogat Date: Fri, 10 Feb 2012 16:27:19 -0800 Subject: meta: Add pixel store/pack operations in decompress_texture_image This patch adds the pixel store operations in decompress_texture_image(). decompress_texture_image() is used in glGetTexImage() for compressed textures with unsigned, normalized values. It also fixes the failures in intel oglconform pxstore-gettex due to following sub test cases: - Test all mipmaps with byte swapping enabled - Test all small mipmaps with all allowable alignment values - Test subimage packing for all mipmap levels Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=40864 Note: This is a candidate for stable branches Signed-off-by: Anuj Phogat Reviewed-by: Brian Paul --- src/mesa/drivers/common/meta.c | 8 +++----- 1 file changed, 3 insertions(+), 5 deletions(-) (limited to 'src/mesa/drivers/common/meta.c') diff --git a/src/mesa/drivers/common/meta.c b/src/mesa/drivers/common/meta.c index 0cf1028c49a..8f5b0360966 100644 --- a/src/mesa/drivers/common/meta.c +++ b/src/mesa/drivers/common/meta.c @@ -3244,7 +3244,7 @@ decompress_texture_image(struct gl_context *ctx, struct gl_texture_image *texImage, GLuint slice, GLenum destFormat, GLenum destType, - GLvoid *dest, GLint destRowLength) + GLvoid *dest) { struct decompress_state *decompress = &ctx->Meta->Decompress; struct gl_texture_object *texObj = texImage->TexObject; @@ -3274,7 +3274,7 @@ decompress_texture_image(struct gl_context *ctx, fboDrawSave = ctx->DrawBuffer->Name; fboReadSave = ctx->ReadBuffer->Name; - _mesa_meta_begin(ctx, MESA_META_ALL); + _mesa_meta_begin(ctx, MESA_META_ALL & ~MESA_META_PIXEL_STORE); /* Create/bind FBO/renderbuffer */ if (decompress->FBO == 0) { @@ -3409,7 +3409,6 @@ decompress_texture_image(struct gl_context *ctx, _mesa_PixelTransferf(GL_BLUE_SCALE, 0.0f); } - ctx->Pack.RowLength = destRowLength; _mesa_ReadPixels(0, 0, width, height, destFormat, destType, dest); } @@ -3450,8 +3449,7 @@ _mesa_meta_GetTexImage(struct gl_context *ctx, const GLuint slice = 0; /* only 2D compressed textures for now */ /* Need to unlock the texture here to prevent deadlock... */ _mesa_unlock_texture(ctx, texObj); - decompress_texture_image(ctx, texImage, slice, format, type, pixels, - ctx->Pack.RowLength); + decompress_texture_image(ctx, texImage, slice, format, type, pixels); /* ... and relock it */ _mesa_lock_texture(ctx, texObj); } -- cgit v1.2.3
