dt_opencl_note_crash_backtrace()

void dt_opencl_note_crash_backtrace	(	const char *	backtrace,
		size_t	backtrace_len
	)

Tell the OpenCL module that the process crashed, and let it judge whether the crash was its driver's doing.

internally calls dt_clGetDeviceInfo, and takes care of memory allocation afterwards, *param_value will point to memory block of size at least *param_value which needs to be g_free()'d manually inits the opencl subsystem.

Vendor OpenCL runtimes fault on their own threads, with no frame of ours on the stack, and no code here can prevent that. What this module can do is notice it happening repeatedly and stop enabling OpenCL on the next start. It recognises its own drivers by name in the backtrace; a crash anywhere else is recorded as nothing.

Sentry captures the backtrace and knows nothing about GPUs; this module knows about GPUs and nothing about crash reporting. dt_init() connects the two, so neither has to include the other.

Parameters

backtrace	NUL-terminated backtrace text, valid only for the duration of the call.
backtrace_len	its length in bytes.

Warning

Runs in a signal handler. Uses only open/write/close – no allocation, no locks, no conf – and does nothing at all before dt_opencl_init() has built the record's path.

dt_opencl_report_pipe_error()

int dt_opencl_report_pipe_error

(

void

)

Record that a pipe run failed on OpenCL, and decide whether to give up on it.

The count and the give-up threshold belong to the OpenCL module, not to the pipeline: the pipeline's job is to report the failure and be told what to do next. Crossing the threshold also drops the "opencl" capability, so this is the one place that decides OpenCL is finished for the session.

Returns

1 for "this run failed, retry on CPU", 2 for "too many failures, OpenCL is off for the rest of the session".

dt_opencl_reserve_device_for_pipe()

int dt_opencl_reserve_device_for_pipe

(

const int

pipetype

)

Reserve a device for a pipe run: choose a free one by the pipe's priority list and take its lock. Blocks or gives up per the opencl_mandatory_timeout conf key.

locks a device for your thread's exclusive use

Parameters

pipetype

a dt_dev_pixelpipe_type_t; selects which priority list applies.

Returns

the reserved device id, or -1 if none could be had. Release with dt_opencl_release_device().

Note

There is ONE lock per device and this is it – reserving a device and locking it are the same act. dt_opencl_reserve_device_by_id() takes the same lock when the caller already knows which device it needs. This used to be called dt_opencl_lock_device(), which took a PIPE TYPE while its dt_opencl_unlock_device() counterpart took a DEVICE ID – two different ints, one of them silently wrong if the pair were ever read as symmetric. The old names are gone rather than redefined, so a stale caller fails to compile.
