| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new power/clock gating functions that can be called by other units. New clock_gating functions will reside in cg.c under common/power_features/cg unit. New power gating functions will reside in pg.c under common/power_features/pg unit. Use nvgpu_pg_elpg_disable and nvgpu_pg_elpg_enable to disable/enable elpg and also in gr_gk20a_elpg_protected macro to access gr registers. Add cg_pg_lock to make elpg_enabled, elcg_enabled, blcg_enabled and slcg_enabled thread safe.

* gpu: nvgpu: vgpu: support clk-arbAparna Das2018-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Implement the following vgpu functions to support clk-arb: - vgpu_clk_get_range() to return min and max freqs from supported frequencies - implement vgpu_clk_get_round_rate() which sets rounded rate to input rate. Rounding is handled in RM Server - modify vgpu_clk_get_freqs() to retrieve freq table in IVM memory instead of copying the value in array as part of cmd message. 2. Add support for clk-arb related HALs for vgpu. 3. support_clk_freq_controller is assigned true for vgpu provided guest VM has the privilege to set clock frequency.

* gpu: nvgpu: Standardize HAS_SYNCPOINTs checkAlex Waterman2018-09-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nvgpu uses many ways to check if sync points are enabled. The four ways used to be: platform->has_syncpoints g->has_syncpoints nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS) gk20a_platform_has_syncpoints() This patch standardizes all usage to now be nvgpu_has_syncpoints() which is based on gk20a_platform_has_syncpoints() - just renamed to be general to nvgpu. All usage of the other forms have now been consolidated. However, under the hood nvgpu_has_syncpoints() does check the is_enabled flag. This flag is now set where g->has_syncpoints used to be set based on the platform data. The basic dependency chain is this: nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS -> platform->has_syncpoints However, note: there are several places where syncpoints can be disabled if some other driver initialization fails (for ex. host1x). Also note that nvgpu_has_syncpoints() also considers a disable variable set by debugfs.
