* gpu: nvgpu: cde: Re-use contextArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | Currently cde reinitialises the context each time before submitting work to the channel. This was done to ensure that we are able to get clean context for the shader during development phase. However, as the shader has been tested to work w/o reinitialising the context, we can remove the reinitialisation to gain better performance.

| | | | | | | | | | | | | | | | Do not force GM20b GPCPLL post divider to 1:2 settings before switching to bypass clock if PLL output frequency is increased as a result. Move this step under bypass. However, this step is still needed in case when PLL can be configured without switch to bypass.

* gpu: nvgpu: gm20b: Fix pm refs in VPR info fetchArto Merilainen2015-03-18
| | | | | | | | | | | | | | | | | The code took reference to gk20a by using gk20a_busy_noresume(). This function takes pm runtime reference only to the GPU, however, the code dropped the reference by calling gk20a_idle() which also drops the reference to the platform dependencies (host1x). This patch modifies gm20b_mm_mmu_vpr_info_fetch_wait() to drop only the GPU reference.

| | | | | | | | | | | | | | | | | | Currently if pmu_mutex_acquire() fails, we disable ELPG and move ahead. But it is not clear why it is required to disable ELPG in case where we fail to acquire mutex. Hence skip disabling ELPG if mutex_acquire() fails Bug 1533644 Change-Id: I7e8e99a701d0ba071eb31ac17582b04072ee55eb Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/448131 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
