* gpu: nvgpu: Make sure there an nvlink.h header for POSIXAlex Waterman2018-05-17
| | | | | | | | | | | | | | | | | | | This header doesn't have anything in it yet but the header is now present. A change recently went in that only checked for __KERNEL__ before falling back to including the QNX header. This caused the POSIX build in GVS to attempt to include the QNX header. The QNX src is not synced in userspace dev-kernel tests builds resulting in a missing header.

* gpu: nvgpu: Update POSIX BIT() macro to ULLAlex Waterman2018-05-17
| | | | | | | | | | | | | | | | | | | | | | | | For most of the builds we have in GVS userspace is 64 bits. But it seems like at least some L4T userspace builds are either not 32 bits or have an UL that only covers 32 bits. This is seen in GVS: /dvs/git/dirty/git-master_modular/kernel/nvgpu/drivers/gpu/nvgpu/gv11b/mm_gv11b.c: In function 'gv11b_gpu_phys_addr': /dvs/git/dirty/git-master_modular/kernel/nvgpu/drivers/gpu/nvgpu/gv11b/mm_gv11b.c:273:3: error: left shift count >= width of type make[2]: *** [/dvs/git/dirty/git-master_modular/tmake/artifacts/CommonRules.tmk:318: mm_gv11b.o] Error 1 This patch simply bumps the UL to ULL in BIT() to make sure that we always have at least 64 bits available for the BIT() macro.

| | | | | | | | | | | | | | | | | | | | | | | | | Currently gpu sysfs retrieves Fmax@Vmin by direct call into Tegra DVFS driver that introduces compile time dependencies on CONFIG_TEGRA_DVFS. In addition incorrect clock is used for DVFS information access. Re-factored sysfs node to use generic GPU clock operation for Fmax@Vmin read. This would fix a bug in target clock selection, and allows to remove dependency of sysfs on CONFIG_TEGRA_DVFS. Updated nvgpu_linux_get_fmax_at_vmin_safe operation itself so it can be called on platforms that does not support Tegra DVFS, although 0 will still be returned as Fmax@Vmin on such platforms.

* gpu: nvgpu: poll watchdog status activelyKonsta Holtta2018-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Read GP_GET and GET from hardware every time when the poll timer expires instead of when the watchdog timer expires. Restart the watchdog timer if the get pointers have increased since the previous read. This way stuck channels are detected quicker. Previously it could have taken at most twice the watchdog timeout limit for a stuck channel to get recovered; with this change, a coarse sliding window is used. The polling period is still 100 ms. The difference is illustrated in the following diagram: time 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 get a b b b b b b b b b b b b b b b b b b b b prev - n n n n n n n n n A n n n n n n n n n S next - A s s s s s s s s s S "time" represents wall time in polling units; 0 is submit time. For simplicity, watchdog timeout is ten units. "get" is the GP_GET that advances a little from a and then gets stuck at b. "prev" is the previous behaviour, "next" is after this patch. "A" is when the channel is detected as advanced, and "S" when it's found stuck and recovered; small "s" is when it's found stuck but when the time limit has not yet expired and "n" is when the hw state is not read.

* gpu: nvgpu: create a wrapper over sync_fencesDebarshi Dutta2018-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch constructs an abstraction to hide the sync_fence functionality from the common code. struct nvgpu_os_fence acts as an abstraction for struct sync_fence. struct nvgpu_os_fence consists of an ops structure named nvgpu_os_fence_ops which contains an API to do pushbuffer programming to generate wait commands for the fence. The current implementation of nvgpu only allows for wait method on a sync_fence which was generated using a similar backend(i.e. either Nvhost Syncpoints or Semaphores). In this patch, a generic API is introduced which will decide the type of the underlying implementation of the struct nvgpu_os_fence at runtime and run the corresponding wait implementation on it. This patch changes the channel_sync_gk20a's semaphore specific implementation to use the abstract API. A subsequent patch will make the changes for the nvhost_syncpoint based implementations as well.

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>

| | | | | | | | | | | | | | | | | | | | | | | | Implement a worker thread to replace the workqueue based handling for clk arbiter update callbacks. The work items scheduled with the thread are of two types, update_vf_table and arb_update. Previously, there were two workqueues for handling these two work struct's separately. Now the single worker thread would process these two events. If a work item of a particular type is scheduled to be run on the worker, another instance of same type won't be scheduled, which mirrors the linux workqueue behavior. This also removes dependency on linux workqueues/work struct and makes code portable to be used by QNX also.

* gpu: nvgpu: remove rcu locks in clk arbiterSourab Gupta2018-05-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCU's are available only in (linux) kernel. Though they are able to achieve lockless access in some specific scenarios, they are heavily dependent on the kernel for their functionality. E.g. synchronize_rcu(), which depends on the kernel in order to delimit read side critical sections. As such it is very difficult to implement constructs analogous to RCUs in userspace code. As a result the code which depends on RCU's for synchronization is not portable between OS'es, especially if one of them is in userspace, viz. QNX. Also, if the code is not in performance critical path, we can do with non-RCU constructs. For clk arbiter code here, RCU's are replaced by the traditional spinlocks, so that the code could be used by QNX down the line.
