* gpu: nvgpu: Prevent integer overflow of GPU configTerje Bergstrom2016-11-11
| | | | | | | | | | | | | | In CDE GPU CONFIGURATION the result is computed using 32-bit arithmetic and returned as 64-bit unsigned integer. Cast intermediate result to u64 to prevent unintentional overflow.

* gpu: nvgpu: vgpu: Do not overwrite err code on failTerje Bergstrom2016-11-11
| | | | | | | | | | | | | | vgpu_vm_alloc_share() wants to return -EINVAL if VMA areas requested do not fulfill the criteria. The error code gets overwritten by a call to vgpu_comm_sendrecv(), which makes vgpu_vm_alloc_share() always return 0.

* gpu: nvgpu: fix semaphore wakeup logicSachit Kadle2016-10-26
| | | | | | | | | | | | | | | | | | | | | | | Currently, when we receive a semaphore wakeup interrupt, we call the channel_update callback, which schedules deferred job clean-up. For deterministic channels, we don't allow semaphore-backed syncs anyways. That means for these channels, if we get a semaphore wakeup interrupt, it must be for a userspace-managed semaphore. In this case, there is no need to call into the channel_update callback. So for deterministic channels, we skip this.

| | | | | | | | | | | | | | | | Coverity detected a possible overflow during the left shift. This is likely not a big problem, though, since the number of pages to allocate would have to be greater than 2^32 (that would be 4 TB of memory assuming 4k page size and the literal 1 being a signed int by default).

* gpu: nvgpu: correct gpfifo size calculationSachit Kadle2016-10-20
| | | | | | | | | | | | | | | | | | | | | | This change fixes up the calculation of gpfifo entries, to be allocated depending on the ioctl used: 1) For the legacy ALLOC_GPFIFO ioctl, we preserve the calculation of gpfifo entries within the kernel. 2) For the new ALLOC_GPFIFO_EX ioctl, we assume that userspace has pre-calculated power-of-2 value. We process this value un-modified and only verify that it is a valid power-of-2.

* gpu: nvgpu: use inplace allocation in sync frameworkSachit Kadle2016-10-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change is the first of a series of changes to support the usage of pre-allocated job tracking resources in the submit path. With this change, we still maintain a dynamically-allocated joblist, but make the necessary changes in the channel_sync & fence framework to use in-place allocations. Specifically, we: 1) Update channel sync framework routines to take in pre-allocated priv_cmd_entry(s) & gk20a_fence(s) rather than dynamically allocating themselves 2) Move allocation of priv_cmd_entry(s) & gk20a_fence(s) to gk20a_submit_prepare_syncs 3) Modify fence framework to have seperate allocation and init APIs. We expose allocation as a seperate API, so the client can allocate the object before passing it into the channel sync framework. 4) Fix clean_up logic in channel sync framework Bug 1795076 Change-Id: I96db457683cd207fd029c31c45f548f98055e844 Signed-off-by: Sachit Kadle <skadle@nvidia.com> Reviewed-on: http://git-master/r/1206725 (cherry picked from commit 9d196fd10db6c2f934c2a53b1fc0500eb4626624) Reviewed-on: http://git-master/r/1223933 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
