* gpu: nvgpu: Initialize hwpm perfmons (engine_sel)Vaibhav Kachore2018-07-10
| | | | | | | | | | | | | | - For Mode-E ctxsw it is required that engine_sel is set to 0xFFFFFFFF. - Default 0 is a valid signal and causes problems.

* gpu: nvgpu: enable HWPM Mode-E context switchVaibhav Kachore2018-07-10
| | | | | | | | | | | | | | | | | | - Write new pm mode to context buffer header. Ucode use this mode to enable mode-e context switch. This is Mode-B context switch of PMs with Mode-E streamout on one context. If this mode is set, Ucode makes sure that Mode-E pipe (perfmons, routers, pma) is idle before it context switches PMs. - This allows us to collect counters in a secure way (i.e. on context basis) with stream out.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist, and optionally check host and FECS status to preempt pending load of context not belonging to the calling channel on GR engine during context switch. This should be called immediately after a submit to decrease worst case submit to start latency for high interleave channel. There is less than 0.002% chance that the ioctl blocks up to couple miliseconds due to race condition of FECS status changing while being read. For GV11B it will always preempt pending load of unwanted context since there is no chance that ioctl blocks due to race condition. Also fix bug with host reschedule for multiple runlists which needs to write both runlist registers.

* gpu: nvgpu: Fix Gpu sysfs access to Fmax@VminAlex Frid2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | Currently gpu sysfs retrieves Fmax@Vmin by direct call into Tegra DVFS driver that introduces compile time dependencies on CONFIG_TEGRA_DVFS. In addition incorrect clock is used for DVFS information access. Re-factored sysfs node to use generic GPU clock operation for Fmax@Vmin read. This would fix a bug in target clock selection, and allows to remove dependency of sysfs on CONFIG_TEGRA_DVFS. Updated nvgpu_linux_get_fmax_at_vmin_safe operation itself so it can be called on platforms that does not support Tegra DVFS, although 0 will still be returned as Fmax@Vmin on such platforms.

| | | | | | | | | | | | | | | | | | | | | | | | Implement a worker thread to replace the workqueue based handling for clk arbiter update callbacks. The work items scheduled with the thread are of two types, update_vf_table and arb_update. Previously, there were two workqueues for handling these two work struct's separately. Now the single worker thread would process these two events. If a work item of a particular type is scheduled to be run on the worker, another instance of same type won't be scheduled, which mirrors the linux workqueue behavior. This also removes dependency on linux workqueues/work struct and makes code portable to be used by QNX also.
