* 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: move debugfs code to linux moduleDeepak Nibade2017-06-02
Since all debugfs code is Linux specific, remove it from common code and move it to Linux module Debugfs code is now divided into below module specific files : common/linux/debug.c common/linux/debug_cde.c common/linux/debug_ce.c common/linux/debug_fifo.c common/linux/debug_gr.c common/linux/debug_mm.c common/linux/debug_allocator.c common/linux/debug_kmem.c common/linux/debug_pmu.c common/linux/debug_sched.c Add corresponding header files for above modules too And compile all of above files only if CONFIG_DEBUG_FS is set Some more details of the changes made - Move and rename gk20a/debug_gk20a.c to common/linux/debug.c - Move and rename gk20a/debug_gk20a.h to include/nvgpu/debug.h - Remove gm20b/debug_gm20b.c and gm20b/debug_gm20b.h and call gk20a_init_debug_ops() directly from gm20b_init_hal() - Update all debug APIs to receive struct gk20a as parameter instead of receiving struct device pointer - Update API gk20a_dmabuf_get_state() to receive struct gk20a pointer instead of struct device - Include <nvgpu/debug.h> explicitly in all files where debug operations are used - Remove "gk20a/platform_gk20a.h" include from HAL files which no longer need this include - Add new API gk20a_debug_deinit() to deinitialize debugfs and call it from gk20a_remove() - Move API gk20a_debug_dump_all_channel_status_ramfc() to gk20a/fifo_gk20a.c Jira NVGPU-62 Change-Id: I076975d3d7f669bdbe9212fa33d98529377feeb6 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1488902 Reviewed-by: svccoveritychecker <svccoveritychecker@nvidia.com> GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
