* gpu: nvgpu: Move Linux files away from commonTerje Bergstrom2018-06-15
| | | | | | | | | | | | | | | Move all Linux source code files to drivers/gpu/nvgpu/os/linux from drivers/gpu/nvgpu/common/linux. This changes the meaning of common to be OS independent.

* gpu: nvgpu: support TSG IOCTL to unbind channelDeepak Nibade2018-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We so far do not support unbinding a channel from TSG explicitly through IOCTL Channel is unbound from TSG when channel fd is closed But this could create issue in case process is forked and fd is duplicated In worst case it is possible that duplicate fd is closed sometime later when TSG is active and that could lead to corruption of TSG state Fix this by implementing NVGPU_TSG_IOCTL_UNBIND_CHANNEL API This API will simply call gk20a_tsg_unbind_channel() API to unbind the channel Note that we also mark the channel has_timedout since unbound channel does not have any context of its own and it cannot serve any job Remove call to gk20a_disable_channel() while closing the channel. We do not support bare channels without TSG, and if channel is not part of TSG then it means channel is already unbound from TSG with call to NVGPU_TSG_IOCTL_UNBIND_CHANNEL, and there is nothing to do while closing the channel Bug 200327095 Jira NVGPU-229 Change-Id: Ib7f6710f0dc8125caafabe7bee737622c3dd9fa3 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1708902 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: Remove gk20a_dbg* functionsTerje Bergstrom2018-05-09
| | | | | | | | | | | | | | | Switch all logging to nvgpu_log*(). gk20a_dbg* macros are intentionally left there because of use from other repositories. Because the new functions do not work without a pointer to struct gk20a, and piping it just for logging is excessive, some log messages are deleted.

* gpu: nvgpu: add g->sw_ready flagKonsta Holtta2018-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | Fix a race condition where we'd still be booting up the gpu and/or initializing the driver but elsewhere assume that all is done already. Some userspace APIs to make sure that we're ready by testing g->gr.sw_ready, but this flag is set in the middle of bootup; there are other things after gr initialization. Add a new flag that is enabled after bootup is fully complete at the end of finalize_poweron, and change the checks in user API paths to test the new flag only. These checks are only in the ioctl paths for ctrl, dbg and tsg, and in the ctrl device's opening path. The gr.sw_ready flag is still left there to signify whether just gr has had its bookkeeping initialized.
