* gpu: nvgpu: Allow comptag to deduct occupied memory by the systemNicolin Chen2018-08-29
| | | | | | | | | | | | | | | | | | | | | | | The comptag allocates memory based on the available total RAM, which theoretically should be the MAX physical RAM size however practically should deduct the part being taken by the running system. Otherwise, the taken memory part will never get used and wasted. This change adds a comptag_mem_deduct to each platform and to allow them to assign the deductible value based on their own use cases so as to save memory.

* gpu: nvgpu: Force the PMU VM to use 128K large pages (gm20b)Alex Waterman2018-08-21
| | | | | | | | | | | | | | | Add a WAR for gm20b that allows us to force the PMU VM to use 128K large pages. For some reason setting the small page size to 64K breaks the PMU boot. Unclear why. Bug needs to be filed and fixed. Once fixed this patch can and should be reverted.

* gpu: nvgpu: tpc powergating through sysfsDeepak Goyal2018-07-24
| | | | | | | | | | | | | | | | | | | | | | | - adds static tpc-powergating through sysfs. - active tpc count will remain till the GPU/systems is not booted again. - tpc_pg_mask can be written only after GPU probe finishes and GPU boot is triggered. Note: To be able to use this feature, we need to change boot/init scripts of the OS(used with nvgpu driver) to write to sysfs nodes before posting discover image size query to FECS.

Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.
