* 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recovery process, the guest OS would remove the channel from the TSG's list, but this would leave the RM server with an out-of-date channel list.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: add SET_CTX_MMU_DEBUG_MODE ioctlThomas Fleury2020-01-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added NVGPU_DBG_GPU_IOCTL_SET_CTX_MMU_DEBUG_MODE ioctl to set MMU debug mode for a given context. Added gr.set_mmu_debug_mode HAL to change NV_PGPC_PRI_MMU_DEBUG_CTRL for a given channel. HAL implementation for native case is gm20b_gr_set_mmu_debug_mode. It internally uses regops, which directly writes to the register if the context is resident, or writes to gr context otherwise. Added NVGPU_SUPPORT_SET_CTX_MMU_DEBUG_MODE to enable the feature. NV_PGPC_PRI_MMU_DEBUG_CTRL has to be context switched in FECS ucode, so the feature is only enabled on TU104 for now.

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.

* 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: 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. As a result pmu_gk20a.h is now removed from gk20a.h JIRA-597 Change-Id: Id54b2684ca39362fda7626238c3116cd49e92080 Signed-off-by: Debarshi Dutta <ddutta@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1804283 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>

| | | | | | | | | | | | | | | | | | | | | | | | | once gpu is powered off i.e. power_on set to false, nvgpu isr does not handle stall/nonstall irq. Depending upon state of gpu, this can result in either of following errors: 1) irq 458: nobody cared (try booting with the "irqpoll" option) 2) "HSM ERROR 42, GPU" from SCE if it detects that an interrupt is not in time. 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.
