* gpu: nvgpu: Add ECC Support for GV11B in LinuxDebarshi Dutta2021-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement nvgpu plumbing to allow reporting ECC errors(corrected and uncorrected) to a L1SS service(if one exists). This patch includes the following 1) Added code that submits ECC error reports via the Interrupt context directly to a L1SS service in linux OS. 2) Added support for enabling/disabling the error reports via L1SS's registration/deregistration API. Nvgpu simply invokes an empty function until the registration is successful. 3) Added Spinlock to correctly handle concurrency for accessing the correct Ops for submitting requests. 4) Adds error reporting for a subset of interrupts that can be verified via external ECC injection logic. A subsequent patch will add the API for rest of the interrupts. 5) In case of critical(uncorrected errors), change nvgpu's state to quiesce state.

* 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.

* gpu: nvgpu: add vidmem allocation APIKonsta Holtta2016-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Add in-nvgpu APIs for allocating and freeing mem_descs in video memory. Changes for gmmu tables etc. will be added in upcoming changes. Video memory is allocated via nvmap by initially registering the aperture size to it and binding it to a struct device, and then going via the usual dma alloc. This API allows also fixed-address allocations, meant for reserving special memory areas at boot. The aperture registration is skipped completely if vidmem isn't found for the particular device. gk20a_gmmu_alloc_attr() still uses sysmem, and the unmap/free paths select internally the correct path by the mem_desc's aperture. Video memory allocation is off by default, and can be turned on with CONFIG_GK20A_VIDMEM.

* gpu: nvgpu: Add support for FECS ctxsw tracingAnton Vorontsov2016-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | bug 1648908 This commit adds support for FECS ctxsw tracing. Code is compiled conditionnaly under CONFIG_GK20_CTXSW_TRACE. This feature requires an updated FECS ucode that writes one record to a ring buffer on each context switch. On RM/Kernel side, the GPU driver reads records from the master ring buffer and generates trace entries into a user-facing VM ring buffer. For each record in the master ring buffer, RM/Kernel has to retrieve the vmid+pid of the user process that submitted related work. Features currently implemented: - master ring buffer allocation - debugfs to dump master ring buffer - FECS record per context switch (with both current and new contexts) - dedicated device for ctxsw tracing (access to VM ring buffer) - SOF generation (and access to PTIMER) - VM ring buffer allocation, and reconfiguration - enable/disable tracing at user level - event-based trace filtering - context_ptr to vmid+pid mapping - read system call for ctxsw dev - mmap system call for ctxsw dev (direct access to VM ring buffer) - poll system call for ctxsw dev - save/restore register on ELPG/CG6 - separate user ring from FECS ring handling Features requiring ucode changes: - enable/disable tracing at FECS level - actual busy time on engine (bug 1642354) - master ring buffer threshold interrupt (P1) - API for GPU to CPU timestamp conversion (P1) - vmid/pid/uid based filtering (P1) Change-Id: I8e39c648221ee0fa09d5df8524b03dca83fe24f3 Signed-off-by: Thomas Fleury <tfleury@nvidia.com> Reviewed-on: http://git-master/r/1022737 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
* drm/tegra: Support NVIDIA downstreamArto Merilainen2015-12-04
| | | | | | | | | | | | | | | | | | | This patch modifies TegraDRM to compile on NVIDIA downstream kernel. Currently buffers are pinned to virtual drm device. In upstream this is ok since the buffers will be remapped into the TegraDRM maintained IOMMU domain. However, NVIDIA downstream kernel relies on DMA mapping API and hence requires that the buffers are pinned to the real hardware device. In addition, this patch modifies code to use downstream power-management APIs if the downstream option is enabled.
