* gpu: nvgpu: Debugfs support for Railgating stats.Deepak Goyal2016-07-18
| | | | | | | | | | | | | | | | | | This patch calculates: -Total time spent by GPU with rails gated. -Total time spent by GPU with rails ungated. -Total Railgating Cycles. and dumps this information in debugfs file. This feature requires CONFIG_DEBUG_FS set to true.

* gpu: nvgpu: simplify power managementDeepak Nibade2016-07-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currenlty initialize both runtime PM and pm_domains frameworks and use pm_domain to control runtime power management of NvGPU But since GPU has a separate rail, using pm_domain is not strictly required Hence remove pm_domain support and use runtime PM only for all the power management This also simplifies the code a lot Initialization in gk20a_pm_init() - if railgate_delay is set, set autosuspend delay of runtime PM - try enabling runtime PM - if runtime PM is now enabled, keep GPU railgated - if runtime PM is not enabled, keep GPU unrailgated - if can_railgate = false, disable runtime PM and keep GPU unrailgated Set gk20a_pm_ops with below callbacks for runtime PM static const struct dev_pm_ops gk20a_pm_ops = { .runtime_resume = gk20a_pm_runtime_resume, .runtime_suspend = gk20a_pm_runtime_suspend, .resume = gk20a_pm_resume, .suspend = gk20a_pm_suspend, } Move gk20a_busy() to use runtime checks of pm_runtime_enabled() instead of using compile time checks on CONFIG_PM Clean up some pm_domain related code Remove use of gk20a_pm_enable/disable_clk() since this should be already done in platform specific unrailgate()/ railgate() APIs Fix "railgate_delay" and "railgate_enable" sysfs to use runtime PM calls For VGPU, disable runtime PM during vgpu_pm_init() With this, we will initialize vgpu with vgpu_pm_finalize_poweron() upon first call to gk20a_busy() Jira DNVGPU-57 Change-Id: I6013e33ae9bd28f35c25271af1239942a4fa0919 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1163216 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: Revamp semaphore supportAlex Waterman2016-06-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revamp the support the nvgpu driver has for semaphores. The original problem with nvgpu's semaphore support is that it required a SW based wait for every semaphore release. This was because for every fence that gk20a_channel_semaphore_wait_fd() waited on a new semaphore was created. This semaphore would then get released by SW when the fence signaled. This meant that for every release there was necessarily a sync_fence_wait_async() call which could block. The latency of this SW wait was enough to cause massive degredation in performance. To fix this a fast path was implemented. When a fence is passed to gk20a_channel_semaphore_wait_fd() that is backed by a GPU semaphore a semaphore acquire is directly used to block the GPU. No longer is a sync_fence_wait_async() performed nor is there an extra semaphore created. To implement this fast path the semaphore memory had to be shared between channels. Previously since a new semaphore was created every time through gk20a_channel_semaphore_wait_fd() what address space a semaphore was mapped into was irrelevant. However, when using the fast path a sempahore may be released on one address space but acquired in another. Sharing the semaphore memory was done by making a fixed GPU mapping in all channels. This mapping points to the semaphore memory (the so called semaphore sea). This global fixed mapping is read-only to make sure no semaphores can be incremented (i.e released) by a malicious channel. Each channel then gets a RW mapping of it's own semaphore. This way a channel may only acquire other channel's semaphores but may both acquire and release its own semaphore. The gk20a fence code was updated to allow introspection of the GPU backed fences. This allows detection of when the fast path can be taken. If the fast path cannot be used (for example when a fence is sync-pt backed) the original slow path is still present. This gets used when the GPU needs to wait on an event from something which only understands how to use sync-pts.

We used to compare that against CE0, but we should compare against CE2. gk20a_fifo_reset_engine() uses wrong constants - it is passed a internal numbering of engines, but it compares them against hardware engine enum.

* gpu: nvgpu: refactor gk20a_mem_{wr,rd} for vidmemKonsta Holtta2016-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support vidmem, pass g and mem_desc to the buffer memory accessor functions. This allows the functions to select the memory access method based on the buffer aperture instead of using the cpu pointer directly (like until now). The selection and aperture support will be in another patch; this patch only refactors these accessors, but keeps the underlying functionality as-is. gk20a_mem_{rd,wr}32() work as previously; add also gk20a_mem_{rd,wr}() for byte-indexed accesses, gk20a_mem_{rd,wr}_n() for memcpy()-like functionality, and gk20a_memset() for filling buffers with a constant. The 8 and 16 bit accessor functions are removed. vmap()/vunmap() pairs are abstracted to gk20a_mem_{begin,end}() to support other types of mappings or conditions where mapping the buffer is unnecessary or different. Several function arguments that would access these buffers are also changed to take a mem_desc instead of a plain cpu pointer. Some relevant occasions are changed to use the accessor functions instead of cpu pointers without them (e.g., memcpying to and from), but the majority of direct accesses will be adjusted later, when the buffers are moved to support vidmem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently bind only one channel to a debug session But some use cases might need multiple channels bound to same debug session Add this support by adding a list of channels to debug session. List structure is implemented as struct dbg_session_channel_data List node dbg_s_list_node is currently defined in struct dbg_session_gk20a. But this is inefficient when we need to add debug session to multiple channels Hence add new reference structure dbg_session_data to store dbg_session pointer and list entry For each NVGPU_DBG_GPU_IOCTL_BIND_CHANNEL call, create two reference structure dbg_session_channel_data for channel and dbg_session_data for debug session and bind them together Define API nvgpu_dbg_gpu_get_session_channel() which will get first channel in the list of debug session Use this API wherever we refer to channel bound to debug session Remove dbg_sessions define in struct gk20a since it is not being used anywhere Add new API NVGPU_DBG_GPU_IOCTL_UNBIND_CHANNEL to support unbinding of channel from debug sesssion Bug 200156699 Change-Id: I3bfa6f9cd5b90e7254a75c7e64ac893739776b7f Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1120331 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>
