* gpu: nvgpu: Remove get and put client routinesKonsta Holtta2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gk20a_get_client() and gk20a_put_client() routines are effectively dead code. The GPU has been using pm_runtime for reference counting whether the device should be turned on or off, and gk20a_get_client() and gk20a_put_client() have had no positive effect on the behaviour. In worst case these functions trigger some issues as they may trigger code paths that should not be run. There is also a race between get/put and busy/idle. This patch removes the functions and reworks as_gk20a.c to correctly use gk20a_busy()/gk20a_idle() where put/get was required. Additionally, finalize_poweron() is moved to gk20a_busy(), similarly as it was with gk20a_get_client(). If pm_runtime is not in use, the device is only powered on and never off. Currently this affects vgpu power management since it does not use pm_runtime yet.

* gpu: nvgpu: Implement 64k large page supportTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | | Implement support for 64kB large page size. Add an API to create an address space via IOCTL so that we can accept flags, and assign one flag for enabling 64kB large page size. Also adds APIs to set per-context large page size. This is possible only on Maxwell, so return error if caller tries to set large page size on Kepler. Default large page size is still 128kB.

* gpu: nvgpu: vgpu: disable GK20A PMU supportHaley Teng2015-03-18
| | | | | | | | | | | | | | | | GK20A PMU is not supported in GPU client for virtualization. However, to make native case and virtualization case can share same defconfig and kernel image, we need to enable CONFIG_GK20A_PMU and CONFIG_GK20A_DEVFREQ in defconfig. This commit changes to detect if we should disable GK20A PMU support in run time.

* gpu: nvgpu: Get host1x device from DTSArto Merilainen2015-03-18
| | | | | | | | | | | | | | | Currently the gpu driver assumes that the GPU is a child of host1x. This is an invalid assumption and therefore we need to get the host1x device from device tree based on nvidia,host1x property.
