* gpu: nvgpu: vgpu: fix tsg_unbind in recovery casePeter Daifuku2020-02-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When unbinding a channel from a tsg when virtual, vgpu_tsg_unbind_channel would return an error if unbinding the channel on the guest side failed, and did so before notifying the RM server of the unbind. Later on in the recovery process, the guest OS would remove the channel from the TSG's list, but this would leave the RM server with an out-of-date channel list. Fix this by making the tsg_unbind_channel HAL optional and implemented only for vgpu: the vgpu version now just notifies the RM server so that it can clean up its version of the TSG; if vgpu, always call the tsg_unbind_channel HAL whether or not the local unbind succeeded.

* gpu: nvgpu: Use TPC_PG_MASK to powergate the TPCDivya Singhatwaria2019-08-02
| | | | | | | | | | | | | | | | | | | | | | | - In GV11B, read fuse_status_opt_tpc_gpc register to read which TPCs are floorswept. - The driver will also read sysfs node: tpc_pg_mask - Based on these two values "can_tpc_powergate" will be set to true or false and mask will be used to write to fuse_ctrl_opt_tpc_gpc register to powergate the TPC. - can_tpc_powergate = true indicates that the mask value sent from userspace is valid and can be used to power gate the desired TPC - can_tpc_powergate = false indicates that the mask value sent from userspace is not valid and cannot be used to power gate the desired TPC.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: move gp106 clk debugfs to linuxNitin Kumbhar2018-09-05
| | | | | | | | | | | | | | | | | | | | | | | | | 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. The linux specific part of nvgpu driver uses this op to initialize gp106 clk debugfs. As gv100 also uses gp106 clk debugfs ops, set up os ops for gv100.

* gpu: nvgpu: move gp106 specific clk_arbiter code into HALDebarshi Dutta2018-09-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Fix these by masking all interrupts just before gpu power off as nvgpu won't be handling any irq anymore. While masking interrupts, if there are any pending interrupts, then report those with a log message.
