* gpu: nvgpu: Fix mutex MISRA 17.7 violationsNicolas Benech2018-09-05
| | | | | | | | | | | | | | | | | | MISRA Rule-17.7 requires the return value of all functions to be used. Fix is either to use the return value or change the function to return void. This patch contains fix for calls to nvgpu_mutex_init and improves related error handling.

* gpu: nvgpu: Move common DMA code to common/mmAlex Waterman2018-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | This migrates the common DMA code (os agnostic) to the common directory. This new unit will be the common DMA allocator that lets users allocate SYSMEM, VIDMEM, or either. Other units will be responsible for actually handling the mechanics of allocating VIDMEM or SYSMEM. Also update the names of the DMA related files so that tmake doesn't complain about duplicate C file names. To do this call the common DMA file dma.c and prepend the OS to the other DMA files. So now we have: common/mm/dma.c os/posix/posix-dma.c os/linux/linux-dma.c JIRA NVGPU-990 Change-Id: I22d2d41803ad89be7d9c28f87864ce4fedf10836 Signed-off-by: Alex Waterman <alexw@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1799807 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

* gpu: nvgpu: fix bad error code in gmmu mapKonsta Holtta2018-09-04
| | | | | | | | | | | | | | | | | | | __nvgpu_gmmu_map() does not currently have a mechanism for returning an error code if something goes wrong; it just returns zero on error, or a nonzero address when mapping was successful. Change it to return 0 instead of -ENOMEM if the creation of nvgpu_sgt from mem fails. Out of memory is the only meaningful failure case anyway, and this -ENOMEM would just look like a (huge) memory address.

* gpu: nvgpu: Add configurable comptag_mem_deduct sysfs node per deviceNicolin Chen2018-09-04
| | | | | | | | | | | | | | | | | | | | | | | Adding a comptag_mem_deduct in the platform_gk20a has certain problems: 1) It's not really convenient for platform users to configure it. 2) All products using the same GPU have to share the same configuration. So this patch moves this comptag_mem_deduct from struct platform_gk20a to struct gr_gk20a (per device). And it adds an sysfs node for products or platform users to easily configure from user space. Note: The comptag memory will not be allocated until the GPU driver goes through the final poweron routine. So the user space has a small window to configure this sysfs node.

This is to enable the clk_arbiter based on support from both the OS and the chips.

The usage is still inside Linux, but this helps the subsequent unification efforts, e.g. to unify the fecs trace path. - Remove "asm/barrier.h" as "nvgpu/barrier.h" is already included.

We can use the reset_enum present in DEVICE_INFO table's IOCTRL entry which is meant to index into NV_PMC_ENABLE_DEVICE register bitfields. This allows us to not #include the MC hardware header in nvlink IP file.

* gpu: nvgpu: Correct the device info table parsingTejal Kudav2018-08-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | We parse the DEVICE_INFO table entries to get IOCTRL(NVLINK) engine related information like the pri_base_addr, reset_enum, and the intr_enum. For grouping the chained entries per IP, the current parsing logic relies on the fact that engine_type entry for an IP will be parsed before other entries in the chained group. As the enum_type entry (which contains the reset_enum) appears ahead of the engine_type entry, the parsing logic fails and we read reset_enum as 0. Modify the parsing logic to group the chained entries correctly. Also we were using a wrong API to extract the reset/intr_enum from the table entry.
