* gpu: nvgpu: update ecc sysfs node handlingNitin Kumbhar2018-06-15
| | | | | | | | | | | | | | | | | | | | | | | | | | Make ecc sysfs hash table per GPU by adding it as part of nvgpu_os_linux. Using a single hash table might give incorrect results as GPUs have same filenames and a filename is used as a key for a lookup. Add device_attribute as part of struct gk20a_ecc_stat. Using a single array of pointers of device attribute for an ecc_stat results in memory leak and incorrect stats if multiple GPUs are present on the system. This array of pointers will always hold info for GPU which created sysfs nodes last. Fix this by making device attribute array per ecc stat per GPU. Fix ecc stat removal to consider zero sub-units for a given number of hwunits. The multiplication with zero results in not removing any sysfs node at all.

* gpu: nvgpu: gpu railgate handling with runtime pmseshendra Gadagottu2018-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Earlier implementation of railgate disable config is disabling runtime pm during pm_init. This is causing multiple issues: 1. gpu rail will be on as soon as nvgpu driver probe is called. Actual gpu hw init may happen at much later point of time. 2. This is breaking railgate_enable sysfs node functionality. railgate_enable is not working if runtime pm is disabled. To avoid all these issues for railgate disable, enable runtime pm during pm_init and set auto-suspend delay to negative (-1), which will disable runtime pm suspend calls. Also fixed following issues along with this: 1. Updated railgate_enable debugfs implementation to use auto-suspend delay. To disable railgating: Set auto-suspend delay with negative value(-1) which will disable runtime pm suspend. To enable railgating: Set auto-suspend delay with railgate_delay value. Also removed redundant user_railgate_disabled gk20a device data and replaced with can_railgate, where ever it is applicable. 2. Initialized default railgate_delay to 500msec to avoid railgate on/off transitions with railigate enable from disabled state. 3. Created railgate_residency debug fs node irrespective of can_railgate initial state. This is helping with the case, where initial state of railgate state off and then railgate enable is done through sysfs node.

* gpu: nvgpu: sync_framework cleanupsDebarshi Dutta2018-04-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deals with cleanups meant to make things simpler for the upcoming os abstraction patches for the sync framework. This patch causes some substantial changes which are listed out as follows. 1) sync_timeline is moved out of gk20a_fence into struct nvgpu_channel_linux. New function pointers are created to facilitate os independent methods for enabling/disabling timeline and are now named as os_fence_framework. These function pointers are located in the struct os_channel under struct gk20a. 2) construction of the channel_sync require nvgpu_finalize_poweron_linux() to be invoked before invocations to nvgpu_init_mm_ce_context(). Hence, these methods are now moved away from gk20a_finalize_poweron() and invoked after nvgpu_finalize_poweron_linux(). 3) sync_fence creation is now delinked from fence construction and move to the channel_sync_gk20a's channel_incr methods. These sync_fences are mainly associated with post_fences. 4) In case userspace requires the sync_fences to be constructed, we try to obtain an fd before the gk20a_channel_submit_gpfifo() instead of trying to do that later. This is used to avoid potential after effects of duplicate work submission due to failure to obtain an unused fd.

* gpu: nvgpu: handle pm suspend/resume with runtime pm disableseshendra Gadagottu2018-04-02
| | | | | | | | | | | | | | | | | | | | | When runtime pm is disabled, then gpu rail will be on as soon as nvgpu module is loaded. If pm suspend/resume called before gpu hw initialization(g->poweron = false) then pm suspend is skipping gpu railgate, which is causing issues with SC7 entry/exit. To fix this issue: 1. During pm suspend, if g->poweron is false, check for runtime pm disable to railgate gpu rail. 2. On pm resume, check for runtime pm disable to enable gpu rail, though gpu driver not initialized.

* gpu: nvgpu: Use our own vmap() for coherent DMA buffersAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | For some reason the GPU does not like the mappings created by the DMA API for coherent sysmem buffers. But a plain vmap() does seem to work. To work around this, when we are using coherent sysmem, force the NO_KERNEL_MAPPING flag to on and then make a vmap() in the nvgpu DMA API wrapper. The rest of the driver will be none the wiser but will work as expected. This problem is not understood yet but it is being tracked in bug 2040115. Once this bug is understood this WAR should either be determined as necessary or reverted with an appropriate fix.

* gpu: nvgpu: Get coherency on gv100 + NVLINK workingAlex Waterman2018-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does a couple of things. First it renames NVGPU_DMA_COHERENT to NVGPU_USE_COHERENT_SYSMEM since the former is somewhat ambiguous in meaning. The latter clearly states what must happen: nvgpu needs to treat sysmem as coherent. This flag does simply follow the state of the DMA API but there's no reason to expect a casual reader of the code to know that when the DMA API is coherent nvgpu must treat sysmem as coherent. One thing to note though: when the dGPU is using PCIe and the PCIe controller is coherent, it doesn't actually matter what we do. However, we use this flag for determining how to make CPU mappings in nvgpu_mem_begin() so this flag is still relevant for the CPU side of things. Next this patch adds a check in the core kernel GMMU mapping routine to make sure that when the NVGPU_USE_COHERENT_SYSMEM flag is set that the IO coherent flag is passed into the mapping code. This is the primary fix that made NVLINK start working. Finally the setting of the USE_COHERENT_SYSMEM flag and the NVGPU_SUPPORT_IO_COHERENCE flag were set both for PCIe and for iGPUs. The iGPU also must correctly match it's CPU mappings and GPU mappings for proper operation.

* gpu: nvgpu: remove dependency on linux header for sim_gk20a*Debarshi Dutta2017-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes linux dependencies from sim_gk20a.h under gk20a/sim_gk20a.h. The following changes are made in this patch. 1) Created a linux based structure sim_gk20a_linux that contains a common sim_gk20a struct inside it. The common struct sim_gk20a doesn't contain any linux specific structs. 2) The common struct sim_gk20a contains an added function pointer which is used to invoke gk20a_sim_esc_readl() method. 3) sim_gk20a.c is moved to nvgpu/common/linux along with a new header sim_gk20a.h that contains the definition of struct sim_gk20a_linux. 4) struct gk20a now contains a pointer of sim_gk20a instead of the entire object. The memory for this struct is allocated and initialized during gk20a_init_support() and freed during invocation of gk20_remove_support(). 5) We first obtain the pointer for struct sim_gk20a_linux from the pointer of sim_gk20a using the container_of method in order to work on the struct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate ctxsw_trace_gk20a.c to common/linux/ctxsw_trace.c. This has been done becasue the ctxsw tracing code is currently too tightly tied to the Linux OS due to usage of a couple system calls: - poll() - mmap() And general Linux driver framework code. As a result pulling the logic out of the FECS tracing code is simply too large a scope for time time being. Instead the code was just copied as much as possible. The HAL ops for the FECS code was hidden behind the FECS tracing config so that the vm_area_struct is not used when QNX does not define said config. All other non-HAL functions called by the FECS ctxsw tracing code ha now also been hidden by this config. This is not pretty but for the time being it seems like the way to go.
