* gpu: nvgpu: add igpu support for clk_arbiter.Debarshi Dutta2018-09-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch constructs clk_arbiter specific code for gp10b as well as gv11b and does the necessary plumbing in the clk_arbiter code. The changes made are as follows. 1) Constructed clk_arb_gp10b.* files which add support for clk_arb related HALS including the nvgpu_clk_arb_init and nvgpu_clk_arb_cb. This doesn't have support for debugfs nor the VFUpdateEvent yet and consequently no support for arb->notifications. 2) Added gpcclk specific variables corresponding to every gpc2clk in a given clk_arb related struct. 3) Linux specific support_clk_freq_controller is assigned true in platform_gp10b.c and platform_gv11b.c files. 4) Incremented the clk_arb_worker.put atomic variable during worker_deinit so as to allow the worker thread to be stopped. 5) Added the flag clk_arb_events_supported as part of struct nvgpu_clk_arb. This flag is used to selectively account for the extra refcounting present in OS specific code i.e. nvgpu_clk_arb_commit_request_fd. For igpus, the extra refcount is reduced during nvgpu_clk_arb_release_completion_dev.

* 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.

Any subsequent call to gk20a_finalize_poweron reinitializes the clk_arb and leading to memory leaks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
