Subject: r300g: fix microtiling for 16-bits-per-channel formats
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d0408cf55d9e8d1d376bd844386ef5c9789a3597;p=mesa.git

r300g: fix microtiling for 16-bits-per-channel formats

These texture formats (like R16G16B16A16_UNORM) were untested until now
because st/mesa doesn't use them. I am testing this with a hacked st/mesa
here.
