From e32f62fadfcde413bcd9b5af61ad884e27ba2bf1 Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Thu, 6 Apr 2017 15:30:01 -0700 Subject: gpu: nvgpu: Move Linux nvgpu_mem fields Hide the Linux specific nvgpu_mem fields so that in subsequent patches core code can instead of using struct sg_table it can use mem_desc. Routines for accessing system specific fields will be added as needed. This is the first step in a fairly major overhaul of the GMMU mapping routines. There are numerous issues with the current design (or lack there of): massively coupled code, system dependencies, disorganization, etc. JIRA NVGPU-12 JIRA NVGPU-30 Change-Id: I2e7d3ae3a07468cfc17c1c642d28ed1b0952474d Signed-off-by: Alex Waterman Reviewed-on: http://git-master/r/1464076 Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/gk20a/fb_gk20a.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'drivers/gpu/nvgpu/gk20a/fb_gk20a.c') diff --git a/drivers/gpu/nvgpu/gk20a/fb_gk20a.c b/drivers/gpu/nvgpu/gk20a/fb_gk20a.c index 214014ce..4a76bd6b 100644 --- a/drivers/gpu/nvgpu/gk20a/fb_gk20a.c +++ b/drivers/gpu/nvgpu/gk20a/fb_gk20a.c @@ -44,9 +44,10 @@ void fb_gk20a_reset(struct gk20a *g) void gk20a_fb_init_hw(struct gk20a *g) { - gk20a_writel(g, fb_niso_flush_sysmem_addr_r(), - g->ops.mm.get_iova_addr(g, g->mm.sysmem_flush.sgt->sgl, 0) - >> 8); + u32 addr = g->ops.mm.get_iova_addr(g, + g->mm.sysmem_flush.priv.sgt->sgl, 0) >> 8; + + gk20a_writel(g, fb_niso_flush_sysmem_addr_r(), addr); } static void gk20a_fb_set_mmu_page_size(struct gk20a *g) -- cgit v1.2.2
