* mesa/readpixels: check strides are equal before skipping conversionDave Airlie2015-09-021-1/+2
| | | | | | | | | | | | | The CTS packed_pixels test checks that readpixels doesn't write into the space between rows, however we fail that here unless we check the format and stride match.

| | | | | | | | | | | | | | | | readpixels_can_use_memcpy will later call _mesa_format_matches_format_and_type which does much tighter checks than these to decide if we can use memcpy for readpixels. Also, the checks do not seem to be extensive enough anyway, since we are checking for signed/unsigned conversion only when the framebuffer has integers, but the same checks could be done for other types anyway, since as long as there is a signed/unsigned conversion we can't memcpy.

* mesa: Fix element count for byte-swaps in texstore, readpix and texgetimageIago Toral Quiroga2015-02-161-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some old format conversion code in pack.c implemented byte-swapping like this: GLint comps = _mesa_components_in_format(dstFormat); GLint swapSize = _mesa_sizeof_packed_type(dstType); if (swapSize == 2) _mesa_swap2((GLushort *) dstAddr, n * comps); else if (swapSize == 4) _mesa_swap4((GLuint *) dstAddr, n * comps); where n is the pixel count. But this is incorrect for packed formats, where _mesa_sizeof_packed_type is already returning the size of a pixel instead of the size of a single component, so multiplying this by the number of components in the format results in a larger element count for _mesa_swap than we want. Unfortunately, we followed the same implementation for byte-swapping in the rewrite of the format conversion code for texstore, readpixels and texgetimage. This patch computes the correct element counts for _mesa_swap calls by computing the bytes per pixel in the image and dividing that by the swap size to obtain the number of swaps required per pixel. Then multiplies that by the number of pixels in the image to obtain the swap count that we need to use. Also, when handling byte-swapping in texstore_rgba, we were ignoring the image's depth. This patch fixes this too. Reviewed-by: Jason Ekstrand <[email protected]> Cc: "10.5" <[email protected]>

| | | | | | | | | | | | | | | | | | | | In commit eeed49f5f290793870c60b5b635b977a732a1eb4, Mark accidentally renamed MESA_FORMAT_S8_Z24 to MESA_FORMAT_Z24_UNORM_X8_UINT and MESA_FORMAT_X8_Z24 to MESA_FORMAT_Z24_UNORM_S8_UINT, reversing their sense. The commit message was correct, but what sed commands actually got run didn't match that. This patch swaps the two enum names, reversing them.

| | | | | | | | | | | | | | | | | | Mesa has a fast path for the generic fallback when using glReadPixels for RGBA data which uses memcpy. However it was really difficult to hit this case because it would not be used if any transferOps are enabled. Any type apart from floating point or non-normalized integer types (so any of the common types) would force enabling clamping so the fast path could not be used. This patch makes it ignore clamping when determining whether to use the fast path if the data type of the buffer is an unsigned normalized type because in that case clamping will not have any effect anyway. https://bugs.freedesktop.org/show_bug.cgi?id=46631 NOTE: This is a candidate for the 8.0 branch.
