From 190756482e62cb57e2bc8c798181e5f0171726fb Mon Sep 17 00:00:00 2001 From: Abdiel Janulgue Date: Wed, 15 Apr 2015 13:04:45 +0300 Subject: i965: Enable hardware-generated binding tables on render path. This patch implements the binding table enable command which is also used to allocate a binding table pool where where hardware-generated binding table entries are flushed into. Each binding table offset in the binding table pool is unique per each shader stage that are enabled within a batch. Also insert the required brw_tracked_state objects to enable hw-generated binding tables in normal render path. v2: - Use MOCS in binding table pool alloc for GEN8 - Fix spurious offset when allocating binding table pool entry and start from zero instead. v3: - Include GEN8 fix for spurious offset above. v4: - Fixup wrong packet length in enable/disable hw-binding table for GEN8 (Ville). - Don't invoke HW-binding table disable command when we dont have resource streamer (Chris). v5: - Reorder the state cache invalidate flush so it happens in-between enabling hw-generated binding tables and the previous sw-binding table GPU state (Chris). v6: - Do the same fix in v5 for gen7_disable_hw_binding_tables(). - Adhere to coding guidelines and make comments more informative.
