* gpu: nvgpu: add channel event id supportDeepak Nibade2016-04-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With NVGPU_IOCTL_CHANNEL_EVENTS_CTRL, nvgpu can raise events to User space. 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: bitmap allocator for comptagsKonsta Holtta2016-01-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restore comptags to be bitmap-allocated, like they were before we had the buddy allocator. The new buddy allocator introduced by e99aa2485f8992eabe3556f3ebcb57bdc8ad91ff (originally 6ab2e0c49cb79ca68d2f83f1d4610783d2eaa79b) is fine for the big VAs, but unsuitable for the small compbit store. This commit reverts partially the combination of the above commit and also one after it, 86fc7ec9a05999bea8de320840b962db3ee11410, that fixed a bug which is not present when using a bitmap. With a bitmap allocator, pruning the extra allocation necessary for user-mapped mode is possible, so that is also restored. The original generic bitmap allocator is not restored; instead, a comptag-only allocator is introduced.

| | | | | | | | | | | | | | At zcull bind we disable whole GR engine. This is unnecessary, so instead disable only the channel and make sure it's unloaded. Introduces also an API in fifo_gk20a.c to do the channel disable. gr_gk20a_ctx_zcull_setup() was always passed true as last parameter, so remove parameter.

| | | | | | | | | | | | | | | | | | | | | | | | | Currently, we first invoke semaphore workqueue on all channels and then clear the interrupt This delay in clearing the interrupt can sometimes lead to dropping of new interrupt If that happens, we never invoke gk20a_channel_semaphore_wakeup() for new semaphore interrupts and semaphore waiting never completes.
