* gpu: nvgpu: vgpu: Get channel referenceDeepak2018-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In vGPU code path, function vgpu_channel_abort_cleanup() does not obtain channel reference before using the channel structure (channel_gk20a) - vgpu_channel_abort_cleanup() is called by vgpu_intr_thread() which runs commands obtained from interrupt queue from RM server. - If there is a scenario where gk20a_channel_release() function runs before guest receives notification from RM server to abort channel cleanup, channel gets freed before vgpu_channel_abort_cleanup() runs. - However, because vgpu_channel_abort_cleanup() does not take explicit reference to the channel, it ends up accessing structures (such as ch->g) which are set to NULL and thus we end up in a crash. - This patch explicitly takes reference of channel before vgpu_channel_abort_cleanup() is called. - If gk20a_channel_release() runs before vgpu_channel_abort_cleanup() and ends up freeing channel, we dont get reference to freed channel in vgpu_channel_abort_cleanup() and thus we return from function rather than continuing with freed channel as was the case previously.

* gpu: nvgpu: RDMA implementationPreetham Chandru R2018-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | This change adds RDMA supports for tegra iGPU. 1. Cuda Process allocates the memory and passes the VA and size to the custom kernel driver. 2. The custom kernel driver maps the user allocated buf and does the DMA to/from it. 3. Only supports iGPU + cudaHostAlloc sysmem 4. Works only for a given process. 5. Address should be sysmem page aligned and size should be multiple of sysmem page size. 6. The custom kernel driver must register a free_callback when get_page() function is called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nvgpu uses many ways to check if sync points are enabled. The four ways used to be: platform->has_syncpoints g->has_syncpoints nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS) gk20a_platform_has_syncpoints() This patch standardizes all usage to now be nvgpu_has_syncpoints() which is based on gk20a_platform_has_syncpoints() - just renamed to be general to nvgpu. All usage of the other forms have now been consolidated. However, under the hood nvgpu_has_syncpoints() does check the is_enabled flag. This flag is now set where g->has_syncpoints used to be set based on the platform data. The basic dependency chain is this: nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS -> platform->has_syncpoints However, note: there are several places where syncpoints can be disabled if some other driver initialization fails (for ex. host1x). Also note that nvgpu_has_syncpoints() also considers a disable variable set by debugfs.
