* gpu: nvgpu: initialize masks for the perfmon counters 3David Ung2020-05-22
| | | | | | | | | | | | | | | | | | | Initialize the perfmon counters #3 masks to be same values as ELPG. Hardware boots up with value NV_PPWR_PMU_IDLE_MASK_1(3) (0x10aa4c) = 0x1030, but ELPG NV_PPWR_PMU_IDLE_MASK_1_SUPP(0) (0x10a9f4) boots up with 0.

* gpu: nvgpu: using pmu counters for load estimatePeng Liu2019-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | PMU counters #0 and #4 are used to count total cycles and busy cycles. These counts are used by podgov to estimate GPU load. PMU idle intr status register is used to monitor overflow. Overflow rarely occurs because frequency governor reads and resets the counters at a high cadence. When overflow occurs, 100% work load is reported to frequency governor.

* gpu: nvgpu: invoke calls to methods in pmu_gk20a.h via HALDebarshi Dutta2018-08-29
| | | | | | | | | | | | | | | | | | | | In nvgpu repository, we have multiple accesses to methods in pmu_gk20a.h which have register accesses. Instead of directly invoking these methods, these are now called via HALs. Some common methods such as pmu_wait_message_cond which donot have any register accesses are moved to pmu_ipc.c and the method declarations are moved to pmu.h. Also, changed gm20b_pmu_dbg to nvgpu_dbg_pmu all across the code base. This would remove all indirect dependencies via gk20a.h into pmu_gk20a.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move much of the remaining generic MM code to a new common location: common/mm/mm.c. Also add a corresponding <nvgpu/mm.h> header. This mostly consists of init and cleanup code to handle the common MM data structures like the VIDMEM code, address spaces for various engines, etc. A few more indepth changes were made as well. 1. alloc_inst_block() has been added to the MM HAL. This used to be defined directly in the gk20a code but it used a register. As a result, if this register hypothetically changes in the future, it would need to become a HAL anyway. This path preempts that and for now just defines all HALs to use the gk20a version. 2. Rename as much as possible: global functions are, for the most part, prepended with nvgpu (there are a few exceptions which I have yet to decide what to do with). Functions that are static are renamed to be as consistent with their functionality as possible since in some cases function effect and function name have diverged.
