* gpu: nvgpu: take power refcount in ISRDeepak Nibade2016-06-08
| | | | | | | | | | | | | | | | | | | | | | | | We sometimes see race conditions where power refcount is zero during ISR or bottom half. If bottom half calls gk20a_busy(), it will lead to boot up of GPU, but it is also possible that we are already trying to poweroff GPU since power refcount is zero Fix this by taking a power refcount with gk20a_busy_noresume() in ISR and then dropping this refcount at the end of bottom half Add new API gk20a_idle_nosuspend() to drop a refcount without initiating suspend Bug 200198908 Bug 1770522 Change-Id: Iec3d4dc8d468f49b71919d2bbc327da48b97bcab Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1160035 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | When thermal throttling triggers gpcclk clock changes, devfreq driver need to have call back for get_cur_freq to get current gpu frequency.

* gpu:nvgpu: add sysfs nodes for ptimer freqSeshendra Gadagottu2016-06-06
| | | | | | | | | | | | | | | | | | | | | | With current ptimer_scale_factor sysfs node, some precision is lost while converting scaling factor to floating point and similarly more precision will be lost while converting back to fixed point. To avoid this, kernel will export following two sysfs nodes: ptimer_ref_freq : ptimer reference frequency( in hz) ptimer_src_freq : ptimer source frequency (in hz) in current chip architecture. Client will apply proper scaling factor by doing ptimer_ref_freq / ptimer_src_freq.

* gpu: nvgpu: Add context reset at golden context initTerje Bergstrom2016-06-04
| | | | | | | | | | | | | | | | | | Part of golden context initialization is in powerup sequence, and part done as part of first channel creation. The sequence is missing a context reset, which causes initialization of golden context to fail on dGPU. Just moving the code to golden context initialization does not work, because iGPU can be rail gated, and part of the sequence is required in GPU boot. Thus a part of context initialization is replicated to golden context init after a context reset.
