* gpu: nvgpu: gv11b: gfxp wfi timeoutseshendra Gadagottu2017-11-29
| | | | | | | | | | | | | | | | | | | | | | For gv11b, configured gfx preemption wfi timeout in usec. Set timeout unit as usec in gr_gv11b_init_preemption_state. Used default timeout as 1msec and this timeout value can be modified through sysfs node: /sys/devices/gpu.0/gfxp_wfi_timeout_count For gp10b: gfxp_wfi_timeout_count is in syclk cycles For gv11b: gfxp_wfi_timeout_count is in usec Bug 2003668 Change-Id: I68d52ce996a83df90b8b3a8164debb07e5cb370f Signed-off-by: seshendra Gadagottu <sgadagottu@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1599658 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Context TSG teardown procedure: 1. Disable scheduling for the engine's runlist via PFIFO_SCHED_DISABLE. This enables SW to determine whether a context has hung later in the process: otherwise, ongoing work on the runlist may keep ENG_STATUS from reaching a steady state. 2. Disable all channels in the TSG being torn down or submit a new runlist that does not contain the TSG. This is to prevent the TSG from being rescheduled once scheduling is reenabled in step 6. 3. a)Initiate a preempt of the TSG by writing NV_PFIFO_PREEMPT with the TSG's ID and the TYPE set to TSG if TSG id is known else do 3b b)Initiate a preempt of the engine by writing the bit associated with its runlist to NV_PFIFO_RUNLIST_PREEMPT. This allows us to begin the preempt process prior to doing the slow register reads needed to determine whether the context has hit any interrupts or is hung. Do not poll NV_PFIFO_RUNLIST_PREEMPT for the preempt to complete. 4. Check for preempt done 5. If a reset is needed as determined by step 4: a. Halt the memory interface for the engine (as per the relevant engine procedure). b. Reset the engine via PMC_ENABLE. c. Take the engine out of reset and reinit the engine (as per the relevant engine procedure) 6. Re-enable scheduling for the engine's runlist via PFIFO_SCHED_ENABLE.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the dependency on the header file "uapi/linux/nvgpu.h" for regops_gk20a.c. The original structure and definitions in the uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The following changes are made in this patch. 1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside regops_gk20a.h. 2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside regops_gk20a.h naming it struct nvgpu_dbg_reg_op. 3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from linux versions to common and vice versa. 4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to struct nvgpu_dbg_reg_op and vice versa. 5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which is copied into the struct nvgpu_dbg_reg_op using the APIs above and after executing the regops handler passes the data back into userspace by copying back data from struct nvgpu_dbg_reg_op to struct nvgpu_dbg_gpu_reg_opi.

* gpu: nvgpu: Fix some barrier usageAlex Waterman2017-11-16
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 81868a187fa3b217368206f17b19309846e8e7fb updated barrier usage to use the nvgpu wrappers and in doing so downgraded many plain barriers {mb(), wmb(), rmb()} to the SMP versions of these barriers. The SMP version of the barriers in question are only issued when running on an SMP machine. In most of the cases mentioned above this is fine since the barriers are present to faciliate proper ordering across CPUs. A single CPU is always coherent with itself, so on a non-SMP case we don't need those barriers. However, there are a few places where the barriers in use (GMMU page table programming, IO accessors, userd) where the barrier usage is for communicating and establishing ordering for the GPU. We need these barriers for both SMP machines and non-SMP machines. Therefor we must use the plain barrier versions.

During pbdma/eng preempt done polling, any stalling interrupts relating to the runlist must be detected and handled in order for the preemption to complete. When PBDMA fault or CE fault occurs, the PBDMA will save out automatically. TSG related to the context in which the fault occurred will not be scheduled again until the fault is handled. In the case of some other issue requiring the engine to be reset, TSG will need to be manually preempted. In all cases, a PBDMA interrupt may occur prior to the PBDMA being able to switch out. SW must handle these interrupts according to the relevant handling procedure before the PBDMA preempt can complete. Opt for eng reset instead of waiting for preemption to be finished when there is any stall interrupt pending during engine context preempt completion.

| * gpu: nvgpu: gv11b: mc_elpg_enable & soc credit init moved to bpmpSeema Khowala2017-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | -Program mc_elpg_enable and mss nvlink soc credits only when bpmp is not running or bpmp is running but underlying platorm is simulation. For simulation, bpmp does not execute hot reset sequence. As part of gpu unpowergate, bpmp will program mc_elpg_enable and also set mss nvlink soc credits after bringing mss nvlink out of reset -Remove updating mc_enable as writes to this register has no effect -Remove fifo_fb_iface_r read/write. This hack was added during initial bring up of emulation platforms Bug 2018223 Bug 200269361 Change-Id: Ie09c259e48295a93c6d15376308186152db973fa Signed-off-by: Seema Khowala <seemaj@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1594495 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
