This series gets coherent render target reads working with the i965 driver and exposes the EXT_shader_framebuffer_fetch extension on Gen9+ platforms. It's dependent on the series I sent last week to make the driver-independent changes to enable framebuffer fetch [1], and the series to enable non-coherent framebuffer fetch in the i965 driver [2]. You can find the whole series and dependencies in a branch here [3]. It's mainly a few compiler back-end changes left to get the feature working.
[PATCH 1/9] i965/eu: Take into account the target cache argument in brw_set_dp_read_message. [PATCH 2/9] i965/eu: Add codegen support for the Gen9+ render target read message. [PATCH 3/9] i965/disasm: Fix RC message type strings on Gen7+. [PATCH 4/9] i965/fs: Define framebuffer read virtual opcode. [PATCH 5/9] i965/fs: Define logical framebuffer read opcode and lower it to physical reads. [PATCH 6/9] i965/fs: Don't CSE render target messages with different target index. [PATCH 7/9] i965/fs: Remove special casing of framebuffer writes in scheduler code. [PATCH 8/9] i965/fs: Hook up coherent framebuffer reads to the NIR front-end. [PATCH 9/9] i965: Expose shader framebuffer fetch extensions on Gen9+.
