From 308d17ef9530f236466a31a7855fc3d5176292d4 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Thu, 28 Nov 2013 01:46:56 -0800 Subject: drm/vmwgfx: Fix dma buffer memory size accounting Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.
