Subject: r600g: fix slice tile max for compressed texture and async dma
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=681707abf2121e9d02c6fd13e312fd103f26949c;p=mesa.git

r600g: fix slice tile max for compressed texture and async dma

Was using the pixel size instead of the number of block for the slice
tile max computation which resulted in dma writing at wrong address.
