From: Marek Olšák Date: Fri, 6 Nov 2015 20:11:16 +0000 (+0100) Subject: radeonsi: rename cache flushing flags once more X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c6012a6650c894e57dba51f8e336f134aad13d61;p=mesa.git radeonsi: rename cache flushing flags once more KCACHE, TC L1 and TC L2 are renamed to: - SMEM L1 - VMEM L1 - GLOBAL L2 You can easily tell what they are used for now. Shaders must deal with coherency issues between both L1s manually, e.g. by setting GLC=1 or by using s_dcache_*. BOTH_ICACHE_KCACHE was an unused definition.
