| | | | | | | | | | | | | | | | | When debug dump is called from an interrupt thread, we do not want to call gk20a_busy() because it causes race in case rail gating is being engaged at the same time.

* gpu: nvgpu: Balance curly bracesAlex Waterman2016-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | In some of the conditionally compiled code in the nvgpu driver there are places where the code looks like: #ifdef LINUX_VERSION_CODE < KERNEL_VERSION(3,18,0) some-loop { #else a-diff-loop { #endif /* Some code... */ } This leaves unbalanced curley braces: two open braces for one close brace. This messes up some editors syntax highlighting and auto- indentation features. This patch puts in the extra brace. It's not necessary for compiling code but it makes some editors much happier.

* gpu: nvgpu: Fix calculation of timeoutTerje Bergstrom2016-06-05
| | | | | | | | | | | Fix calculation of timeout in multiple places. The #defines GR_IDLE_CHECK_DEFAULT and GR_IDLE_CHECK_MAX are meant to be used only for defining the frequency of checking for timeout. Using them for actual timeouts makes the timeout really short.

* 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.
