Author: Eric Anholt <[email protected]> Date: Fri Apr 15 13:17:26 2016 -0700 vc4: Sanity check strides for imported BOs. If we're going to sample from or render to them at some particular size, we'd better make sure that they actually are that size. Causes some tests under simulation to generate appropriate error messages instead of failures. --- src/gallium/drivers/vc4/vc4_resource.c | 23 ++++++++++++++++++----- 1 file changed, 18 insertions(+), 5 deletions(-) diff --git a/src/gallium/drivers/vc4/vc4_resource.c b/src/gallium/drivers/vc4/vc4_resource.c index ea212af..2f89da5 100644 --- a/src/gallium/drivers/vc4/vc4_resource.c +++ b/src/gallium/drivers/vc4/vc4_resource.c @@ -529,20 +529,33 @@ vc4_resource_from_handle(struct pipe_screen *pscreen, struct vc4_resource *rsc = vc4_resource_setup(pscreen, tmpl); struct pipe_resource *prsc = &rsc->base.b; struct vc4_resource_slice *slice = &rsc->slices[0]; + uint32_t expected_stride = align(prsc->width0 / rsc->cpp, + vc4_utile_width(rsc->cpp)); if (!rsc) return NULL; + if (handle->stride != expected_stride) { + static bool warned = false; + if (!warned) { + warned = true; + fprintf(stderr, + "Attempting to import %dx%d %s with " + "unsupported stride %d instead of %d\n", + prsc->width0, prsc->height0, + util_format_short_name(prsc->format), + handle->stride, + expected_stride); + } + return NULL; + } + rsc->tiled = false; rsc->bo = vc4_screen_bo_from_handle(pscreen, handle); if (!rsc->bo) goto fail; - if (!using_vc4_simulator) - slice->stride = handle->stride; - else - slice->stride = align(prsc->width0 * rsc->cpp, 16); - + slice->stride = handle->stride; slice->tiling = VC4_TILING_FORMAT_LINEAR; rsc->vc4_format = get_resource_texture_format(prsc); _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
