This is a note to let you know that I've just added the patch titled MIPS: Loongson-3: Reserve 32MB for RS780E integrated GPU to the 4.6-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-loongson-3-reserve-32mb-for-rs780e-integrated-gpu.patch and it can be found in the queue-4.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 3484de7bcbed20ecbf2b8d80671619e7059e2dd7 Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@xxxxxxxxxx> Date: Thu, 17 Mar 2016 20:41:05 +0800 Subject: MIPS: Loongson-3: Reserve 32MB for RS780E integrated GPU From: Huacai Chen <chenhc@xxxxxxxxxx> commit 3484de7bcbed20ecbf2b8d80671619e7059e2dd7 upstream. Due to datasheet, reserving 0xff800000~0xffffffff (8MB below 4GB) is not enough for RS780E integrated GPU's TOM (top of memory) registers and MSI/MSI-x memory region, so we reserve 0xfe000000~0xffffffff (32MB below 4GB).
