* gpu: nvgpu: gpu railgate handling with runtime pmseshendra Gadagottu2018-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier implementation of railgate disable config is disabling runtime pm during pm_init. This is causing multiple issues: 1. gpu rail will be on as soon as nvgpu driver probe is called. Actual gpu hw init may happen at much later point of time. 2. This is breaking railgate_enable sysfs node functionality. railgate_enable is not working if runtime pm is disabled. To avoid all these issues for railgate disable, enable runtime pm during pm_init and set auto-suspend delay to negative (-1), which will disable runtime pm suspend calls. Also fixed following issues along with this: 1. Updated railgate_enable debugfs implementation to use auto-suspend delay. To disable railgating: Set auto-suspend delay with negative value(-1) which will disable runtime pm suspend. To enable railgating: Set auto-suspend delay with railgate_delay value. Also removed redundant user_railgate_disabled gk20a device data and replaced with can_railgate, where ever it is applicable. 2. Initialized default railgate_delay to 500msec to avoid railgate on/off transitions with railigate enable from disabled state. 3. Created railgate_residency debug fs node irrespective of can_railgate initial state. This is helping with the case, where initial state of railgate state off and then railgate enable is done through sysfs node.

* gpu: nvgpu: Set DMA mask on a per-platform basisAlex Waterman2018-06-14
| | | | | | | | | | | | | | | | | | | | Each GPU platform has different DMA limitations. For older chips the maximum size of a DMA buffer was more limited than newer SoCs (read: Xavier) and discrete GPUs. This patch adds support to set the DMA mask for a GPU on a per platform basis by adding a platform field that is populated with the maximum allowed DMA mask. That mask is programmed by the driver common code. If no mask is specified then the default mask size is 16GB (34 bits).
