* gpu: nvgpu: fix reset clock in gm20bDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | To assert reset on GPU, we store "gpu_ref" clock in platform->clk[0] and use it to assert/deassert reset But for gm20b, "gpu_ref" is no longer resettable. To fix this, add two callbacks in gk20a_platform : .reset_assert and .reset_deassert Also, add a pointer "clk_reset" to store the clock which needs to be reset For gk20a specific implementation, we continue to reset platform->clk[0] For gm20b specific implementation, we first request "gpu_gate" clock, store it and use it to assert reset Bug 1513685 Bug 1517584 Change-Id: I15a583a4a07eb663b442084be8b8c7d0c7c7a142 Signed-off-by: Deepak Nibade <dnibade@nvidia.com>

* 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: allow building as a separate moduleKonsta Holtta2015-03-18
| | | | | | | | | | | | | | | Include object files of gk20a, gm20b and vgpu in the same composite object nvgpu.o in the top-level makefile, and remove the old makefiles. This helps in building the driver as a separate module.
