* 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.

* gpu: nvgpu: rename has_timedout and make it thread safeSeema Khowala2019-02-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently has_timedout variable is protected by wmb at places where it is being set and there is no correspoding rmb whenever has_timedout variable is read. This is prone to errors for concurrent execution. This change is supposed to fix this issue. Rename has_timedout variable of channel struct to ch_timedout. Also to avoid rmb every time ch_timedout is read, ch_timedout_spinlock is added to protect ch_timedout variable for taking care of concurrent execution.

* gpu: nvgpu: add safe channel id lookupKonsta Holtta2019-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add gk20a_channel_from_id() to retrieve a channel, given a raw channel ID, with a reference taken (or NULL if the channel was dead). This makes it harder to mistakenly use a channel that's dead and thus uncovers bugs sooner. Convert code to use the new lookup when applicable; work remains to convert complex uses where a ref should have been taken but hasn't. The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is returned for such IDs. This is often useful and does not hurt when unnecessary. However, this does not prevent the case where a channel would be closed and reopened again when someone would hold a stale channel number. In all such conditions the caller should hold a reference already. The only conditions where a channel can be safely looked up by an id and used without taking a ref are when initializing or deinitializing the list of channels.

* gpu: nvgpu: vgpu: Get channel referenceDeepak2018-12-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - In vGPU code path, function vgpu_channel_abort_cleanup() does not obtain channel reference before using the channel structure (channel_gk20a) - vgpu_channel_abort_cleanup() is called by vgpu_intr_thread() which runs commands obtained from interrupt queue from RM server. - If there is a scenario where gk20a_channel_release() function runs before guest receives notification from RM server to abort channel cleanup, channel gets freed before vgpu_channel_abort_cleanup() runs. - However, because vgpu_channel_abort_cleanup() does not take explicit reference to the channel, it ends up accessing structures (such as ch->g) which are set to NULL and thus we end up in a crash. - This patch explicitly takes reference of channel before vgpu_channel_abort_cleanup() is called. - If gk20a_channel_release() runs before vgpu_channel_abort_cleanup() and ends up freeing channel, we dont get reference to freed channel in vgpu_channel_abort_cleanup() and thus we return from function rather than continuing with freed channel as was the case previously.

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

| | | | | | | | | | | | | | | | | | | | | Add abstraction of IO aperture accessors. Add new functions gk20a_io_exists() and gk20a_io_valid_reg() to remove dependencies to aperture fields from common code. Implement Linux version of the abstraction by moving gk20a_readl() and gk20a_writel() to new Linux specific io.c. Move the fields defining IO aperture to nvgpu_os_linux. Add t19x specific IO aperture initialization functions and add t19x specific section to nvgpu_os_linux.
