* gpu: nvgpu: Remove gk20a_dbg* functionsTerje Bergstrom2018-05-09
| | | | | | | | | | | | | | | Switch all logging to nvgpu_log*(). gk20a_dbg* macros are intentionally left there because of use from other repositories. Because the new functions do not work without a pointer to struct gk20a, and piping it just for logging is excessive, some log messages are deleted.

* 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.

Add a new flag that is enabled after bootup is fully complete at the end of finalize_poweron, and change the checks in user API paths to test the new flag only. These checks are only in the ioctl paths for ctrl, dbg and tsg, and in the ctrl device's opening path. The gr.sw_ready flag is still left there to signify whether just gr has had its bookkeeping initialized.

| | | | | | | | | | | | | | | | | | | | | | | | | Delte the Linux headers and make some modifications to get rid of the minor compilation issues that resulted. - Add <linux/iommu.h> to os_linux.h - Delete #if 0 code that "flushed" a buffer in gr_gk20a.c - Delete FLUSH_CPU_DCACHE() macro - Move the cache flush definitions to <nvgpu/linux/vm.h> and include this header in sim_gk20a.c. This file will not be used by QNX so this should be fine. - Add <linux/pci_ids.h> to gp106/bios_gp106.c and gp106/mclk_gp106.c. - Move function to common/linux/dmabuf.h since it is a dmabuf related function and uses a struct device pointer as an argument.

* gpu: nvgpu: hal for timestamps correlationThomas Fleury2017-06-15
| | | | | | | | | | | | | | | | | | | | | | | | In order to perform timestamps correlation for FECS traces, we need to collect GPU / GPU timestamps samples. In virtualization case, it is possible for a guest to get GPU timestamps by using read_ptimer. However, if the CPU timestamp is read on guest side, and the GPU timestamp is read on vm-server side, then it introduces some latency that will create an artificial offset for GPU timestamps (~2 us in average). For better CPU / GPU timestamps correlation, Added a command to collect all timestamps on vm-server side.
