From: Ben Skeggs Date: Fri, 22 Jan 2010 03:17:28 +0000 (+1000) Subject: drm/nv40: make INIT_COMPUTE_MEM a NOP, just like nv50 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e235c1f3e132a243a1f81b3d95c99ee199b4d3f3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/nv40: make INIT_COMPUTE_MEM a NOP, just like nv50 It appears we aren't required to do memory sizing ourselves on nv40 either. NV40 init tables read a strap from PEXTDEV_BOOT_0 into a CRTC register, and then later use that value to select a memory configuration (written to PFB_CFG0, just like INIT_COMPUTE_MEM on earlier cards) with INIT_IO_RESTRICT_PROG.
