The only boot_board script we have is arch/arm/boards/at91sam9m10g45ek/env/bin/boot_board. Here a menu is built which I think makes sense at that stage and not at init_board. However, I would be glad to get rid of defaultenv-1 rather sooner than later.

The thing is, if boot_board is called from init, then it will not be called if autoboot is interrupted and you later boot manually with the boot command. We actually use boot_board to do some board-specific processing that should be done both when autobooting and when booting "manually". The way it is right now, this is not possible. With the change I am proposing, boards such as at91sam9m10g45ek could still do what they are doing now (just move the code to init_board instead). Or, with some tweaking, perhaps it could even be left in boot_board (with boot_board being called from boot). Is this specific board the only objection to the change I am proposing? If so I could try to come up with a patch which accomodates this specific case. Or are there other, more general objections? > > However, I would be glad to get rid of defaultenv-1 rather sooner than > later. Uhm. I actually like defaultenv-1 better than defaultenv-2. Why not keep both?

I guess it is just a matter of personal preference but I find defaultenv-1 easier to understand and easier to manage. With defaultenv-1 we basically have just one configuration file to edit (/env/config) and optionally init_board and/or boot_board (which are not needed in a majority of the cases). So everything you need to know/edit/tweak is in /env/config. With defaultenv-2 the "board configuration" is scattered through a number of tiny files, some of which contain just a single value (see for example nv/autoboot_timeout or nv/user). I find this more difficult to manage -- you need to edit a lot of tiny files instead of just one. Also I feel that the flow of control is less obvious for the same reason. I'd say defaultenv-1 feels more "imperative" and defaultenv-2 feels more "declarative", and I prefer the former. But I am fully aware that this is just a matter of personal preference :) Guillermo _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 11+ messages in thread

Hi, on my device I use defaultenv-1 for the same reason. Basically I just have one env/bin/init and one env/config file and that's it. And the env/config one is even so small that I could fold it into env/bin/init. This even more so as my device is "set in stone", e.g. there is no SPI EEPROM or other means (partition) to store an environment. What comes with the compiled barebox is the environment. Having things in one place and not scattered around makes things visible at a glance. _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 11+ messages in thread

But I am fully aware that > this is just a matter of personal preference :) I understand your concerns but do not share them all. Maybe we can find a way to either make defaultenv-2 more acceptable for you or to make defaultenv-1 more appealing to me? About the number of small files that only contain a single value: defaultenv-1 was the opposite and that was a problem. Whenever a board wanted to adjust a single value, say the autoboot timeout, it had to duplicate a big file and very soon we had many nearly identical copies of that file and nobody knew what the actual change was. With NV variables this has become better. I never felt the need though to dig through the individual /env/nv files, here the 'nv' and 'global' commands or the 'magicvar' command to much better jobs. Normally you only have to hand edit /env/nv files when you want to change the default of a variable for a given board. Another thing that made another approach than with defaultenv-1 necessary was the variables that contain "net", "disk", "nor", "nand". This did not scale and was not extensible because you could not pass some arbitrary file and use it as kernel. I wonder if defaultenv-1 is not customizable enough and on the other hand your board does only boot from very special locations, do you need a generic default environment at all or are you better off using your own special environment? Finally, could this be a documentation issue? Could you have another look at defaultenv-2 and see what is not clear or what needs further convenience to be better usable?

Not sure what you mean with duplicating a big file. With defaultenv-1 most of the time the only single file you need to edit is /env/config, which is quite small, and most of it should be board specific anyway. I find this (the fact that all I need to edit/tweak is in that single file) quite convenient. > With NV > variables this has become better.

I can understand that one. But on the other hand not every target needs that flexibility. That's why I said that I don't see the need to drop defaultenv-1. Isn't it better to leave both defaultenv-1 and defaultenv-2 alive and let everyone decide which one suits them best? My impression when I look at defaultenv-2 is as described above: OK, more flexibility (which I currently don't need), but also more complexity, configuration scattered over more files, more management overhead. Plus, I'm happy with defaultenv-1, so why change? > > I wonder if defaultenv-1 is not customizable enough and on the other > hand your board does only boot from very special locations, do you need > a generic default environment at all or are you better off using your > own special environment? In my case, I am currently using barebox on 3 boards. All of them support multiple boot sources (NAND, NOR, MMC) plus NFS. For all of them I only needed to edit /env/config; the other files in the default environment (init, update, boot) all work fine. So (for me) defaultenv-1 was customizable enough, and I did indeed benefit from having a generic default environment instead of a custom one written from scratch. > > Finally, could this be a documentation issue?

Perhaps a tutorial showing how to migrate from defaultenv-1 to defaultenv-2 could help "convert" people to defaultenv-2 by holding their hand and taking them from what they know (defaultenv-1) to the "new stuff". But even then I still wonder -- why not let both approaches coexist?

It's my interest to keep the diversion between boards small. Normally as a barebox user you shouldn't care about the particular type of the board you have, instead it should always feel the same (Or, if you decide to customize barebox via Kconfig or patches, it should be applyable for all boards without having to repeat this step for every board you use in the future). defaultenv-1 make this goal hard to archieve. Most boards only copy and modify /env/config, but some also duplicate /env/boot and other files. /env/boot is problematic because it contains behaviour, not configuration. With each duplication we introduce a new behaviour which means that this board beahves different from the rest of the boards and also won't get updates from the generic /env/boot file anymore. This all is not problematic when you only care about one board or a few boards that you use, but is a nightmare when you have > 100 boards from which you only have access to a few of them. defaultenv-2 is better in this regard since we can do adjustments without changing other things and it generally needs less adjustments. I think it's not really defaultenv-1 that disturbs me, but more the in-tree users of it. Also it's not really nice that by choosing a board you also choose between defaultenv-1 and defaultenv-2. It would be much nicer if these choices were independent.
