* gpu: nvgpu: use nvgpu list for channel and debug session listsDeepak Nibade2017-04-10

* gpu: nvgpu: Remove last Linux kmem usageAlex Waterman2017-04-04
| | | | | | | | | | | | | | | | | | Replace the last of the Linux kmem API usage with nvgpu kmem calls instead. Several places are left alone - allocating the struct gk20a in particular. Also one function was updated in the clk code to take a struct gk20a as an argument so that it could use nvgpu_kmalloc().

* gpu: nvgpu: refactor teardown to support unbindDavid Nieto2017-03-25
| | | | | | | | | | | | | | | | | | | | | | | | This change refactors the teardown in remove to ensure that it is possible to unload the driver while leaving fds open. This is achieved by making sure that the SW state is kept alive till all fds are closed and by checking that subsequent calls to ioctls after the teardown fail. Normally, this would be achieved ny calls into gk20a_busy(), but in kickoff we dont call into that to reduce latency, so we need to check the driver status directly, and also in some of the functions as we need to make sure the ioctl does not dereference the device or platform struct bug 200277762 JIRA: EVLR-1023 Change-Id: I163e47a08c29d4d5b3ab79f0eb531ef234f40bde Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: http://git-master/r/1320219 Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> Reviewed-by: Shreshtha Sahu <ssahu@nvidia.com> Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | Change nvgpu_kalloc() to nvgpu_big_[mz]alloc(). This is necessary since the natural free function name for this is nvgpu_kfree() but that conflicts with nvgpu_k[mz]alloc() (implemented in a subsequent patch). This API exists becasue not all allocation sizes can be determined at compile time and in some cases sizes may vary across the system page size. Thus always using kmalloc() could lead to OOM errors due to fragmentation. But always using vmalloc() is wastful of memory for small allocations. This API tries to alleviate those problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently bind only one channel to a debug session But some use cases might need multiple channels bound to same debug session Add this support by adding a list of channels to debug session. List structure is implemented as struct dbg_session_channel_data List node dbg_s_list_node is currently defined in struct dbg_session_gk20a. But this is inefficient when we need to add debug session to multiple channels Hence add new reference structure dbg_session_data to store dbg_session pointer and list entry For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create two reference structure dbg_session_channel_data for channel and dbg_session_data for debug session and bind them together Define API nvgpu_dbg_gpu_get_session_channel() which will get first channel in the list of debug session Use this API wherever we refer to channel bound to debug session Remove dbg_sessions define in struct gk20a since it is not being used anywhere Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support unbinding of channel from debug sesssion Bug 200156699 Change-Id: I3bfa6f9cd5b90e7254a75c7e64ac893739776b7f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120331 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
