| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

But user space cannot distinguish between various types of events. To overcome this, we need finer-grained API to deliver various events to user space. Remove old API NVGPU_IOCTL_CHANNEL_EVENTS_CTRL, and all the support for this API (we can remove this since User space has not started using this API at all) Add new API NVGPU_IOCTL_CHANNEL_EVENT_ID_CTRL which will accept an event_id (like BPT.INT or BPT.PAUSE), a command to enable the event, and return a file descriptor on which we can raise the event (if cmd=enable) Event is disabled when file descriptor is closed Add file operations "gk20a_event_id_ops" to support polling on event fd Also add API gk20a_channel_get_event_data_from_id() to get event_data of event from its id Bug 200089620 Change-Id: I5288f19f38ff49448c46338c33b2a927c9e02254 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1030775 (cherry picked from commit 5721ce2735950440bedc2b86f851db08ed593275) Reviewed-on: http://git-master/r/1120318 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

* 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>

* gpu: nvgpu: improve channel interleave supportAingara Paramakuru2016-03-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, only "high" priority bare channels were interleaved between all other bare channels and TSGs. This patch decouples priority from interleaving and introduces 3 levels for interleaving a bare channel or TSG: high, medium, and low. The levels define the number of times a channel or TSG will appear on a runlist (see nvgpu.h for details). By default, all bare channels and TSGs are set to interleave level low. Userspace can then request the interleave level to be increased via the CHANNEL_SET_RUNLIST_INTERLEAVE ioctl (TSG-specific ioctl will be added later). As timeslice settings will soon be coming from userspace, the default timeslice for "high" priority channels has been restored.
