* gpu: nvgpu: Return gr_ctx_resident from NVGPU_DBG_GPU_IOCTL_REG_OPSAnup Mahindre2018-09-09
| | | | | | | | | | | | | | | | | | NVGPU_DBG_GPU_IOCTL_REG_OPS currently doesn't return if the ctx was resident in engine or not. Regops are broken down into batches of 128 and each batch is executed together. Since there only 32 bits were available in IOCTL args, returning is ctx was resident isn't possible for all batches. Hence return if the ctx was resident for the first batch.

* gpu: nvgpu: Read sm error ioctl support for tsgVinod G2018-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | Add READ_SM_ERROR IOCTL support to TSG level. Moved the struct to save the sm_error details from gr to tsg as the sm_error support is context based, not global. Also corrected MISRA 21.1 error in header file. nvgpu_dbg_gpu_ioctl_write_single_sm_error_state and nvgpu_dbg_gpu_ioctl_read_single_sm_error_state functions are modified to use the tsg struct nvgpu_tsg_sm_error_state.

* gpu: nvgpu: enable HWPM Mode-E context switchVaibhav Kachore2018-07-10
| | | | | | | | | | | | | | | | | | - Write new pm mode to context buffer header. Ucode use this mode to enable mode-e context switch. This is Mode-B context switch of PMs with Mode-E streamout on one context. If this mode is set, Ucode makes sure that Mode-E pipe (perfmons, routers, pma) is idle before it context switches PMs. - This allows us to collect counters in a secure way (i.e. on context basis) with stream out.

| | | | | | | | | | | | | | | | | | | | | | Provide concrete documentation for the VM mapping API. This shall be the gold standard! One of the major goals of this API is to keep the design simple. There are features that could be implemented in the kernel but were explictly chosen not to be. Example: partial mappings. The less work the kernel does the easier it is to verify against the API specifications. Security follows as well: the more simple the API the easier it is to ensure there are no easily exploitable corner cases.

| | | | | | | | | | | | | | | | | | | | | | | Add NVGPU_IOCTL_CHANNEL_RESCHEDULE_RUNLIST ioctl to reschedule runlist, and optionally check host and FECS status to preempt pending load of context not belonging to the calling channel on GR engine during context switch. This should be called immediately after a submit to decrease worst case submit to start latency for high interleave channel. There is less than 0.002% chance that the ioctl blocks up to couple miliseconds due to race condition of FECS status changing while being read. For GV11B it will always preempt pending load of unwanted context since there is no chance that ioctl blocks due to race condition. Also fix bug with host reschedule for multiple runlists which needs to write both runlist registers.

| | | | | | | | | | | | | | | | | | | | | | Add support for compiling nvgpu in a POSIX compliant userspace. This code adds all of the necessary abstraction interfaces (mostly stubbed) to enabled extremely limited and basic functionality in nvgpu. The goal of this code is to facilitate unit testing of the nvgpu common core. By doing this in userspace it is much easier to write tests that rely on very particular states within nvgpu since a user can very precisely control the state of nvgpu.

* gpu: nvgpu: support per-channel wdt timeoutsKonsta Holtta2018-03-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the padding in nvgpu_channel_wdt_args with a timeout value in milliseconds, and add NVGPU_IOCTL_CHANNEL_WDT_FLAG_SET_TIMEOUT to signify the existence of this new field. When the new flag is included in the value of wdt_status, the field is used to set a per-channel timeout to override the per-GPU default. Add NVGPU_IOCTL_CHANNEL_WDT_FLAG_DISABLE_DUMP to disable the long debug dump when a timed out channel gets recovered by the watchdog. Printing the dump to serial console takes easily several seconds. (Note that there is NVGPU_TIMEOUT_FLAG_DISABLE_DUMP about ctxsw timeout separately for NVGPU_IOCTL_CHANNEL_SET_TIMEOUT_EX as well.) The behaviour of NVGPU_IOCTL_CHANNEL_WDT is changed so that either NVGPU_IOCTL_CHANNEL_ENABLE_WDT or NVGPU_IOCTL_CHANNEL_DISABLE_WDT has to be set. The old behaviour was that other values were silently ignored. The usage of the global default debugfs-controlled ch_wdt_timeout_ms is changed so that its value takes effect only for newly opened channels instead of in realtime. Also, zero value no longer means that the watchdog is disabled; there is a separate flag for that after all. gk20a_fifo_recover_tsg used to ignore the value of "verbose" when no engines were found. Correct this.

This allows the common MM code to not depend on the UAPI header defined for Linux. In addition to this change a couple of other small changes were made: 1. Deprecate, print a warning, and ignore usage of the NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag. 2. Move the t19x IO coherence flag from the t19x UAPI header to the regular UAPI header.

In the native case, we return 0xffffffff to indicate that the buffer size is unbounded (subject to memory availability), in the virtual case we return the size of the mempool. Also collapse native init_cyclestats functions to a single version, as each chip had identical versions of the code.
