* gpu: nvgpu: defer channel worker initializationDavid Nieto2017-09-22
| | | | | | | | | | | | | | | | | | | | | | | | kthread_run can fail if SIGKILL is triggered on an application during driver load. On this change we defer the channel worker init to the enqueue to avoid this condition during driver power on which would cause the driver state to be corrupted leaving subsequent attempts to load the driver unsuccesful. By moving this code to a later time, it is now needed to protect the task structure with a mutex.

* gpu: nvgpu: prevent crash during unbindDavid Nieto2017-09-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change solves crashes during bind that were introduced in the driver during the OS unification refactoring due to lack of coverage of the remove() function. The fixes during remove are: (1) Prevent NULL dereference on GPUs with secure boot (2) Prevent NULL dereferences when fecs_trace is not enabled (3) Added PRAMIN blocker during driver removal if HW is no longer accesible (4) Prevent double free of debugfs nodes as they are handled on the debugfs_remove_recursive() call (5) quiesce() can now be called without checking is HW accesible flag is set (6) added function to free irq so no IRQ association is left on the driver after it is removed (7) prevent NULL dereference on nvgpu_thread_stop() if the thread is already stopped JIRA: EVLR-1739 Change-Id: I787d38f202d5267a6b34815f23e1bc88110e8455 Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1563005 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
* gpu: nvgpu: fix channel unbind sequence from TSGDeepak Nibade2017-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We right now remove a channel from TSG list and disable all the channels in TSG while removing a channel from TSG With this sequence if any one channel in TSG is closed, rest of the channels are set as timed out and cannot be used anymore We need to fix this sequence as below to allow removing a channel from active TSG so that rest of the channels can still be used - disable all channels of TSG - preempt TSG - check if CTX_RELOAD is set if support is available if CTX_RELOAD is set on channel, it should be moved to some other channel - check if FAULTED is set if support is available - if NEXT is set on channel then it means channel is still active print out an error in this case for the time being until properly handled - remove the channel from runlist - remove channel from TSG list - re-enable rest of the channels in TSG - clean up the channel (same as regular channels) Add below fifo operations to support checking channel status g->ops.fifo.tsg_verify_status_ctx_reload g->ops.fifo.tsg_verify_status_faulted Define ops.fifo.tsg_verify_status_ctx_reload operation for gm20b/gp10b/gp106 as gm20b_fifo_tsg_verify_status_ctx_reload() This API will check if channel to be released has CTX_RELOAD set, if yes CTX_RELOAD needs to be moved to some other channel in TSG Remove static from channel_gk20a_update_runlist() and export it Bug 200327095 Change-Id: I0dd4be7c7e0b9b759389ec12c5a148a4b919d3e2 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1560637 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Seshendra Gadagottu <sgadagottu@nvidia.com> Reviewed-by: Terje Bergstrom <tbergstrom@nvidia.com>

* gpu: nvgpu: hold power ref for deterministic channelsKonsta Holtta2017-06-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To support deterministic channels even with platforms where railgating is supported, have each deterministic-marked channel hold a power reference during their lifetime, and skip taking power refs for jobs in submit path for those. Previously, railgating blocked deterministic submits in general because of gk20a_busy()/gk20a_idle() calls in submit path possibly taking time and more significantly because the gpu may need turning on which takes a nondeterministic and long amount of time. As an exception, gk20a_do_idle() can still block deterministic submits until gk20a_do_unidle() is called. Add a rwsem to guard this. VPR resize needs do_idle, which conflicts with deterministic channels' requirement to keep the GPU on. This is documented in the ioctl header now. Make NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING always set in the gpu characteristics now that it's supported. The only thing left now blocking NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL is the sync framework. Make the channel debug dump show which channels are deterministic.

* gpu: nvgpu: Split VM interface outAlex Waterman2017-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch begins the major rework of the GPU's virtual memory manager (VMM). The VMM is the piece of code that handles the userspace interface to buffers and their mappings into the GMMU. The core data structure is the VM - for now still known as 'struct vm_gk20a'. Each one of these structs represents one addres space to which channels or TSGs may bind themselves to. The VMM splits the interface up into two broad categories. First there's the common, OS independent interfaces; and second there's the OS specific interfaces. OS independent -------------- This is the code that manages the lifetime of VMs, the buffers inside VMs (search, batch mapping) creation, destruction, etc. OS Specific ----------- This handles mapping of buffers represented as they are represented by the OS (dma_buf's for example on Linux). This patch is by no means complete. There's still Linux specific functions scattered in ostensibly OS independent code. This is the first step. A patch that rewrites everything in one go would simply be too big to effectively review. Instead the goal of this change is to simply separate out the basic OS specific and OS agnostic interfaces into their own header files. The next series of patches will start to pull the relevant implementations into OS specific C files and common C files.

| | | | | | | | | | | | | | | | | | | | | | | | | Add these bits in the gpu characteristics flags: NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_NO_JOBTRACKING - fast submits with no in-kernel job tracking are supported. NVGPU_GPU_FLAGS_SUPPORT_DETERMINISTIC_SUBMIT_FULL - deterministic submits also with job tracking and num_inflight_jobs set are supported. Either of these may get disabled if the particular channel or submit still requires features that block these. Make gk20a_channel_sync_needs_sync_framework() take a gk20a pointer instead of a channel pointer so that it can be called without a channel. It does not need any per-channel data.
