That's _got_ to be an improvement. Sorry Master, but you really don't need to spend so much time typing the same things three times - I understand what are you trying to do :( I did my comments with assumption that it's not officially prohibited/deprecated to register drivers (and execute probes) from late_initcall() layer (just recommended) and there are still bunch of drivers which are doing this. Now I see that it's not a recommendation any more, and deferred_probe_initcall() might be a good place to activate driver_deferred_probe_report if goal is to identify and fix such drivers.

I've applied truncated version of your patch (diff below) on TI's 4.1 kernel and run few tests (log is below) on dra7-evm/am43xx-gpevm - K4.1 is not far away from LKML, so I assume this test is valid. Overall boot process consists from two stages: kernel boot and modules loading. My Changes: - only really_probe() modified to show deferred device/drivers >From the log I can see additional messages in log when modules are loading, because driver_deferred_probe_report is still true - dwc3 probes were deferred, but then finally succeeded. So, as you've mentioned, it seems a good thing to deactivate driver_deferred_probe_report and provide user with ability to turn it on again (and probably re-trigger deferred device probing). I've found no issues during Kernel boot (built-in) time, new messages are displayed only if probe is failed for some drivers: [ 3.219700] ====================================== deferred_probe_initcalll [ 3.226820] platform omapdrm.0: Driver omapdrm requests probe deferral [ 3.233378] platform omapdrm.0: deferring probe: ==== Driver omapdrm requests probe deferral [ 3.242084] dra7evm-tpd12s015 encoder@1: failed to parse CT CP HPD gpio [ 3.248737] platform encoder@1: Driver dra7evm-tpd12s015 requests probe deferral [ 3.256168] platform encoder@1: deferring probe: ==== Driver dra7evm-tpd12s015 requests probe deferral [ 3.265763] connector-hdmi connector@1: failed to find video source [ 3.272067] platform connector@1: Driver connector-hdmi requests probe deferral [ 3.279410] platform connector@1: deferring probe: ==== Driver connector-hdmi requests probe deferral ^^ above drivers will be deferred forever Thanks. -- regards, -grygorii S/ILKP *************** [TEST CODE] *********** --- drivers/base/dd.c | 33 ++++++++++++++++++++++++++++++++- 1 file changed, 32 insertions(+), 1 deletion(-) diff --git a/drivers/base/dd.c b/drivers/base/dd.c index e7d2545..d61fa47 100644 --- a/drivers/base/dd.c +++ b/drivers/base/dd.c @@ -129,6 +129,27 @@ void driver_deferred_probe_del(struct device *dev) mutex_unlock(&deferred_probe_mutex); } +static bool driver_deferred_probe_report; + +/** + * dev_warn_deferred() - report why a probe has been deferred + */ +void dev_warn_deferred(struct device *dev, const char *fmt, ...) +{ + if (driver_deferred_probe_report) { + struct va_format vaf; + va_list ap; + + va_start(ap, fmt); + vaf.fmt = fmt; + vaf.va = ≈ + + dev_err(dev, "deferring probe: %pV", &vaf); + va_end(ap); + } +} +EXPORT_SYMBOL_GPL(dev_warn_deferred); + static bool driver_deferred_probe_enable = false; /** * driver_deferred_probe_trigger() - Kick off re-probing deferred devices @@ -188,6 +209,15 @@ static int deferred_probe_initcall(void) driver_deferred_probe_trigger(); /* Sort as many dependencies as possible before exiting initcalls */ flush_workqueue(deferred_wq); + + pr_err("====================================== deferred_probe_initcalll\n"); + + /* Now one final round, reporting any devices that remain deferred */ + driver_deferred_probe_report = true; + driver_deferred_probe_trigger(); + /* Sort as many dependencies as possible before exiting initcalls */ + flush_workqueue(deferred_wq); + return 0; } late_initcall(deferred_probe_initcall); @@ -342,7 +372,8 @@ probe_failed: switch (ret) { case -EPROBE_DEFER: /* Driver requested deferred probing */ - dev_dbg(dev, "Driver %s requests probe deferral\n", drv->name); + dev_err(dev, "Driver %s requests probe deferral\n", drv->name); + dev_warn_deferred(dev, "==== Driver %s requests probe deferral\n", drv->name); driver_deferred_probe_add(dev); /* Did a trigger occur while probing?
