* 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: 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.
