* gpu: nvgpu: vgpu: flatten out vgpu halPeter Daifuku2017-10-13
| | | | | | | | | | | | | | | Instead of calling the native HAL init function then adding multiple layers of modification for VGPU, flatten out the sequence so that all entry points are set statically and visible in a single file.

* gpu: nvgpu: vgpu: profiler reservation supportPeter Daifuku2017-03-24
| | | | | | | | | | | | | | | | | | | | | | | Support for hwpm reservations in the virtual case: - Add session ops for checking and setting global and context reservations, and releasing reservations - in the native case, these just update reservation counts and flags - in the vgpu case, when the reservation count is 0, check with the RM server that a reservation is possible: for global reservations, no other guest can have a reservation; for context reservations, no other guest can have a global reservation - in the vgpu case, when the reservation count is decremented to 0, notify the RM server that the guest no longer has any reservations Bug 1775465 JIRA VFND-3428 Change-Id: Idf115b730e465e35d0745c96a8f8ab6b645c7cae Signed-off-by: Peter Daifuku <pdaifuku@nvidia.com> Reviewed-on: http://git-master/r/1323375 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: support binding multiple channels to a debug sessionDeepak Nibade2016-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
