* gpu: nvgpu: make tsgid a consistent typePhilip Elcan2019-02-05
| | | | | | | | | | | | | | | | | | Different units were declaring tsgid as int or u32. This makes everyone use u32. This change resolves MISRA 10.3 violations for implicit assingment to different types.

* nvgpu: include: MISRA Rule 21.2 header guard fixessmadhavan2018-09-27
| | | | | | | | | | | | | | | | | | | | MISRA rule 21.2 doesn't allow the use of macro names which start with an underscore. These leading underscores are to be removed from the macro names. This patch will fix such violations in the include directory by renaming them to follow the convention, 'NVGPU_HEADER_H'.

* gpu: nvgpu: fix some MISRA 10.3 violationsPhilip Elcan2018-09-10
| | | | | | | | | | | | | | | | Fix MISRA 10.3 violations in mclk_gp106.c. Cleanup cases where values were being assigned to narrower types. Changes in mclk_gp106.c required updates to other files to resolve errors and prevent introducing new violations.

* 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.

* gpu: nvgpu: Userspace POSIX supportAlex Waterman2018-05-07
| | | | | | | | | | | | | | | | | | | | | | Add support for compiling nvgpu in a POSIX compliant userspace. This code adds all of the necessary abstraction interfaces (mostly stubbed) to enabled extremely limited and basic functionality in nvgpu. The goal of this code is to facilitate unit testing of the nvgpu common core. By doing this in userspace it is much easier to write tests that rely on very particular states within nvgpu since a user can very precisely control the state of nvgpu.

* gpu: nvgpu: include rmos headers in common headersSourab Gupta2017-08-31
| | | | | | | | | | | | | | | | | | | Currently nvgpu common header files include the Linux specific headers protected by __KERNEL__ check. The patch includes the rmos specific headers when the common headers (and common nvgpu files, by extension) are compiled under QNX, so that QNX specific data structures / type definitions can be retrieved.

Add wrapper header nvgpu/types.h. It checks if build is for Linux kernel and pulls in linux/types.h. Delete also all #includes for linux/types.h which are not strictly necessary, and change the remaining ones to use the new wrapper.
