* gpu: nvgpu: Fixes to static offset mappingsArto Merilainen2015-03-18
| | | | | | | | | | | | | | This patch addresses two issues in fixes offset mappings: - VA unmapping did not use lists safely. This caused an application hang if the application did not free all (fixed offset) buffers before quiting. - GPU was not powered closing AS node. If the address space had areas that were not freed, the driver tried to access hw without powering it up first.

| | | | | | | | | | | | | | | | | | | | | | On channel_finish() path, we first check if last submit was WFI and in that case we do not submit new WFI but just wait on old syncpt fence. But it is possible that sync resource is already freed from another path (channel_suspend()) Hence add a NULL check there to prevent Null pointer exception. Also, in channel_free() path, move syncpt free API after channel_unbind() since we logically free the syncpt after unbinding the channel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | All of the channel's submit jobs are added to the list channel->jobs In channel_update(), we iterate over this list and check if any job has completed. If any job is complete then we remove it from the list. If this list is empty then it means channel is idle and we can free its syncpt. Hence after iterating this list, check if it is empty or not. If it is empty AND if we are aggressive to free the syncpt (syncpt_aggressive_destroy flag is set) then free the syncpt at this point. Keep the syncpt free code inside submit_lock to avoid race conditions. Also, do not free the syncpt if we have already scheduled WFI on some other path. In that case, syncpt is still needed to check for channel idle. Once WFI completes, we free the syncpt anyway.

* video: tegra: gpu: provide generic ops interfaceAlex Waterman2015-03-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds an interface for the gk20a driver to have generic ops which are implemented by a chip specific HAL layer. The HAL layer is provided by the gpu_ops struct which defines function pointers for chip specific oeprations. This is necessary for supporting multiple chips with the same code base and minimal per chip hacking. Also, since much code is common except in the HW headers that are needed, the LTC common code is compiled by first including the necessary chip specific header(s) and then including the ltc common code file. This allows for easy updating of functions that are only different between chips as a result of register offset and field changes whereas the HAL provides the mechanism for functions that have actual semantic changes.

| | | | | | | | | | | | | | | | | | | This adds new IOCTL that provides information for the userspace for GPU characterization. Specifically, the following items are provided: GPU arch/impl/rev, number of GPCs, L2 cache size, on-board video memory size, num of tpc:s per gpc, and bus type. The primary user of the new IOCTL will be rmapi_tegra.

* gpu: nvgpu: Turn off scaling when not poweredSantosh Katvate2015-03-18
| | | | | | | | | | | | | | | | | | | | | This far the scaling has been disabled only when we suspend the system and therefore we unnecessarily keep gpu workers running even if the gpu itself would be railgated. This is not proper behaviour and it causes a race in suspend sequence. This patch reorders scaling disable to happen always when we turn off the GPU.
