* 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>

| | | | | | | | | | | | | | | | | | | | | | | | | Move linux dependencies and CONFIG_DEBUG_FS to linux specific code from common driver for gp106 clk debugfs. There is no code change in functions moved from gp106/clk_gp106.c. It uses nvgpu_os_linux_ops to add gp106 specific clk debugfs ops.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, clock arbiter code is extensively using dgpu specific implementation. This patch restructures the clk_arbiter code and moves gp106 specific code into HAL. Following changes are made in this patch 1) clk_domain_get_f_points is now invoked via HAL for gp106 i.e. g->ops.clk.clk_domain_get_f_points. 2) moved nvgpu_clk_arb_change_vf_point and other related static functions to clk_arb_gp106.c. 3) Instead of only checking if get_arbiter_clk_domain is empty, a check for support_clk_freq_controller is also added. This is to enable the clk_arbiter based on support from both the OS and the chips.

| | | | | | | | | | | | | | | | | | | | | | | MISRA Rule 10.4 only allows the usage of arithmetic operations on operands of the same essential type category. Adding "U" at the end of the integer literals to have same type of operands when an arithmetic operation is performed. This fix violations where an arithmetic operation is performed on signed and unsigned int types.

* gpu: nvgpu: Use NVLINK config instead of has_physical_modeAlex Waterman2018-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This flag - has_physical_mode - doesn't seem to do much other than force the PTE/PDE and inst block addresses to be physical instead of potentially IOMMUed. There is a reason to do this on volta (nvlink not being IOMMU'able being the primary reason) but this flag is too general it seems. The flag was being enabled on all native platforms. The problem is that some page tables (the maxwell small page directories) could be larger than 4KB which meant that the allocation used for them could be potentially discontiguous. Discontiguous page directories obviously is incorrect. This patch deletes the has_physical_mode flag and instead replaces the places where it's checked with a check for nvlink being enabled. Since we _do_ want to program phyiscal PDEs and PTEs for NVLINK devices (regardless of IOMMU status they always access memory by physical address) we need a check for NVLINK state.

* gpu: nvgpu: Add U64() and U32() macrosAlex Waterman2018-08-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These macros exist to make integer literals used in certain arithmetic operations explicitly large enough to hold the results of that operation. The following is an example of this. In MISRA the destination for a bitwise shift must be able to hold the number of bits shifted. Otherwise the results are undefined. For example: 256U << 20U This is valid C code but the results of this _may_ be undefined if the size of an unsigned by default is less than 24 bits (i.e 16 bits). The MISRA misra checker sees the 256U and determines that the 256U fits in a 16 bit data type (i.e a u16). Since a u16 has 16 bits, which is less than 20, this is an issue. Of course most compilers these days use 32 bits for the default unsigned type this is not a requirement. Moreover this name problem could exist like so: 0xfffffU << 40U The 0xfffffU is a 32 bit unsigned type; but we are shifting 40 bits which overflows the 32 bit data type. So in this case we need an explicit cast to 64 bits in order to prevent undefined behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | The use of the _THIS_IP_ macro in nvgpu introduces two separate MISRA Rule 11.6 violations. The first is when when the label address (which gcc generates as a void *) is cast to an unsigned long and the second is when that unsigned long is cast back to a void * in the timer and kmem code that track the value. Skipping the intermediate use of unsigned long eliminates these violations. To do this, references to _THIS_IP_ are replaced with a new (compliant) _NVGPU_GET_IP_ macro.
