* gpu: nvgpu: Update GM20b GPCPLL operationsAlex Frid2015-03-18
| | | | | | | | | | | | | | | | | | | | | | Moved detection of idempotent GPCPLL operations from set_pll_freq() function to its callers, e.g., explicitly check when enable operation is called on already enabled PLL, instead of passing same frequency to set_pll_freq() in such case. Similarly explicitly check when disable operation is called on already disabled PLL. Also moved check for GPU powered on from set_pll_freq() to callers, and skip call to set interface if not. Added last GPCPLL configuration structure updated after successful completion of set_pll_freq() function.

| | | | | | | | | | | | | | | | | | | In gk20a_do_idle(), to get pointer to platform_device of gk20a, we use bus_find_device_by_name() and pass "gk20a.0" to it But this hard coding fails on gm20b since GPU device name there is "gpu" Hence to fix this add a static pointer handle "gk20a_handle" to struct gk20a in gk20a.c Now we can access this global pointer inside do_idle() to get gk20a pointer and from that we can get pointer to platform_device Change-Id: I1a65588e34ad36efed0fa587bb365f0ee81e253d Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/486887 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

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.

* gpu: nvgpu: do not touch runlist during recoveryDeepak Nibade2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | Currently we clear the runlist and re-create it in scheduled work during fifo recovery process But we can post-pone this runlist re-generation for later time i.e. when channel is closed Hence, remove runlist locks and re-generation from handle_mmu_fault() methods. Instead of that, disable gr fifo access at start of recovery and re-enable it at end of recovery process. Also, delete scheduled work to re-create runlist. Re-enable EPLG and fifo access in finish_mmu_fault_handling() itself. bug 1470692 Change-Id: I705a6a5236734c7207a01d9a9fa9eca22bdbe7eb Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/449225 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Tested-by: Terje Bergstrom <tbergstrom@nvidia.com>
