I'm happy to go either way. I guess I didn't do that originally because logically there's not any reason to link the two drivers going forward. Said another way, someone enabling the "simple panel" driver for non-eDP panels wouldn't expect that the "simple panel" driver for DP panels would also get enabled by default. They really have nothing to do with one another. Enabling by default for something like this also seems like it would lead to bloat. I could have sworn that periodically people get yelled at for marking drivers on by default when it doesn't make sense. ...that being said, I'm happy to change the default as you suggest. Just let me know. -Doug

I guess this is just misunderstanding. Symbol names: CONFIG_DRM_PANEL_SIMPLE=y CONFIG_DRM_PANEL_SIMPLE_EDP=y suggests that CONFIG_DRM_PANEL_SIMPLE_EDP is an 'suboption' of CONFIG_DRM_PANEL_SIMPLE, but these symbols are independent - old symbol has been split into two independent new symbols. So Doug's approach seems correct to me. Maybe one could change names of symbols to avoid confusion(?). One more thing, I suspect previous patch can break platforms with EDP panels. Even if this patch fixes it, maybe it would be better to squash these patches? Or add temporal solution to save bisecatability. Regards Andrzej > > -Doug >

OK, so I'm trying to figure out how to do this without just "kicking the can" down the road. I guess your idea is that for the next year this will be the default and that anyone who really wants "CONFIG_DRM_PANEL_EDP" will "opt-in" to keep it by adding "CONFIG_DRM_PANEL_EDP=y" to their config? ...and then after a year passes we remove the default? ...but that won't work, will it? Since "CONFIG_DRM_PANEL_EDP" will be the default for the next year then you really can't add it to the "defconfig", at least if you ever "normalize" it. The "defconfig" by definition has everything stripped from it that's already the "default", so for the next year anyone who tries to opt-in will get their preference stripped. Hrm, so let me explain options as I see them. Maybe someone can point out something that I missed. I'll assume that we'll change the config option from CONFIG_DRM_PANEL_SIMPLE_EDP to CONFIG_DRM_PANEL_EDP (remove the "SIMPLE" part). == Where we were before my series: * One config "CONFIG_DRM_PANEL_SIMPLE" and it enables simple non-eDP and eDP drivers. == Option 1: update everyone's configs (this patch) * Keep old config "CONFIG_DRM_PANEL_SIMPLE" but it now only means enable the panel-simple (non-eDP) driver. * Anyone who wants eDP panels must opt-in to "CONFIG_DRM_PANEL_EDP" * Update all configs in mainline; any out-of mainline configs must figure this out themselves. Pros: * no long term baggage Cons: * patch upstream is a bit of "churn" * anyone with downstream config will have to figure out what happened. == Option 2: kick the can down the road + accept cruft * Keep old config "CONFIG_DRM_PANEL_SIMPLE" and it means enable the panel-simple (non-eDP) driver. * Anyone with "CONFIG_DRM_PANEL_SIMPLE" is opted in by default to "CONFIG_DRM_PANEL_EDP" AKA: config DRM_PANEL_EDP default DRM_PANEL_SIMPLE Pros: * no config patches needed upstream at all and everything just works! Cons: * people are opted in to extra cruft by default and need to know to turn it off. * unclear if we can change the default without the same problems. == Option 3: try to be clever * Add _two_ new configs. CONFIG_DRM_PANEL_SIMPLE_V2 and CONFIG_DRM_PANEL_EDP. * Old config "CONFIG_DRM_PANEL_SIMPLE" gets marked as "deprecated". * Both new configs have "default CONFIG_DRM_PANEL_SIMPLE" Now anyone old will magically get both the new config options by default. Anyone looking at this in the future _won't_ set the deprecated CONFIG_DRM_PANEL_SIMPLE but will instead choose if they want either the eDP or "simple" driver. Pros: * No long term baggage. * Everyone is transitioned automatically by default with no cruft patches. Cons: * I can't think of a better name than "CONFIG_DRM_PANEL_SIMPLE_V2" and that name is ugly. == Option 4: shave a yak When thinking about this I came up with a clever idea of stashing the kernel version in a defconfig when it's generated. Then you could do something like: config DRM_PANEL_EDP default DRM_PANEL_SIMPLE if DEFCONFIG_GENERATED_AT <= 0x00050f00 That feels like a good idea to me but who knows what others would think. In general I think this series already shaves enough yaks. This isn't a new problem we're trying to solve so it seems like we should pick one of the options above. == Unless I get an explicit NAK from someone like Olof or Arnd or I hear that everyone loves Option #3 I'll probably just stick with the existing approach since: * Olof's wording didn't make it sound like a strong objection. * From git history it looks as if config patches don't necessarily land through the SoC tree and thus I'd by default follow the suggestions of the DRM folks. Andrzej suggested going with the existing approach as long as I changed the symbol names and re-ordered the patches. Please yell if anything above sounds wrong! I'll probably try to send out a new version tomorrow or the next day, but I won't land it right away to give people time to yell. -Doug

Yeah, not a strong objection but an enquiry if there's a better way to handle it. TL;DR: I don't think there really is. My comment mostly came from the fact that when olddefconfig gets broken like this, we tend to have a bunch of patches trickle in over time as downstream users discover the need to turn on the new option. You covered (most) of that by doing the appropriate defconfigs to this patch series, so it won't be as bad (besides any newly added defconfigs during the same release, and we're quite careful about doing that these days). I think most of the other options, besides 2, are just more overhead than needed here. So I'd be fine with just picking up option 1. What's clear is that this is not a very convenient activity that scales, but we don't do it all that often. This is where something like a "HAVE_EDP" type config that the platform can provide helps, but adding it just for this rework seems to be more work than it's worth. > * From git history it looks as if config patches don't necessarily > land through the SoC tree and thus I'd by default follow the > suggestions of the DRM folks.

Right, Kconfig changes usually go with the driver. dts and defconfig changes go to the SoC tree though since otherwise we end up with a bunch of churn and conflicts. > Please yell if anything above sounds wrong! I'll probably try to send > out a new version tomorrow or the next day, but I won't land it right > away to give people time to yell. I'd leave it up to you if you want to do option 1 or 2, since there's no really convenient way to do it better. 3 seems to be a bigger hammer than what this situation calls for IMHO. -Olof

In the patch ("drm/panel-simple-edp: Split eDP panels out of panel-simple") we split the PANEL_SIMPLE driver in 2. By default let's give everyone who had the old driver enabled the new driver too. If folks want to opt-out of one or the other they always can later.
