Put something like this in your modprobe.conf install b43 case "$(uname -r)" in 2.6.25*) /sbin/insmod b43 fwprefix=new;; /sbin/insmod b43;; esac It's not tested. It should only illustrate the idea!

The problem is _not_ to actually need a newer firmware for a newer kernel. That can be managed easily and was simple for the change bcm43xx -> b43. However, being able to use different kernel version painlessly is a major feature. Modprobe cannot use different configs for different kernel versions, so the fwpostfix option doesn't help in userspace. The only work-around would be to change /lib/udev/firmware.agent to also use the kernel version when looping over possible firmware directories. Clumsy at best, especially since the driver knows best about the difference. I already suggested to make the ABI part of the directory name (maybe even kill fwpostfix for it, anyone actually using that one for real?). That's a one-minute change in the driver (one #define and one other one-liner in main.c) and an additional table field in fwcutter. You have to update the latter anyway to let it know about the new firmware files, anyway. With that, you can require a different firmware ABI on kernel version change and possible noone will complain. And you don't have to support multiple ABIs at the same time.

It's just the > word "fwprefix" that makes me allergic. Please note that nobody suggested to use "fwpostfix" in order to support regular migration from a kernel version to another one. That was proposed as a convenient way in order to switch back and forth between two kernel versions. Did anybody ever complain about ipw2200 very frequent firmware changes between kernel versions (i.e. http://ipw2200.sourceforge.net/firmware.php)? This would be the second firmware change for bcm43xx/b43. Please also note then that having b43-fwcutter to rename firmware according to its capabilities could be disruptive too (as people already have a lot of fun by downloading unsupported firmwares, and this would just confuse the users even more). A big fat printk that tells the user that the firmware found in /lib/firmware is unsupported and displays a linuxwireless.org URL seems the best solution to me. But again, Michael wasn't even talking about one particular implementation, he just wanted to warn in advance about a likely firmware change in the future. I know that distros out there are having even more fun than users in messing up this sort of things, but this can't really be claimed to be our fault. -- Ciao Stefano ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

Impossible, sorry. We are going to add support for new firmware, which will be needed for N-PHY, or we don't. And I think it's clear which way we are going. What's the problem with all of this? Other drivers change firmware to incompatible versions on a regular basis. Look at ipw2200. There was a time when they changed the firmware basically on every kernel release. That wasn't a problem. Why would it be a problem here? How the technical implementation of all that stuff works in the end is not up to this discussion. Maybe we can support both firmware in one driver for some limited time. Maybe we rename the firmware files once again. I think it's likely to end up with a driver supporting 2 fw versions for a few release cycles. But I simply can not tell you, yet. I just wanted to tell people that a firmware change is going to happen soon. Just informational stuff. Nothing people need to complain, suggest or argue about. -- Greetings Michael. ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

Mind you, there is nothing fundamentally wrong with changing firmware or changing its API. Sure, Broadcom firmware is not under GPL, so we have to keep it in separate files rather than link it into the kernel. But the same situation exists for many other drivers, even those where the vendors are much more cooperative, such as Intel. If the firmware is kept outside the kernel, we have a problem of synchronization between the driver and the firmware. It can be addressed gracefully, or not so gracefully. The choice is entirely ours, and Broadcom is not to blame for our choice. -- Regards, Pavel Roskin ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

As you already mentioned fwpostfix: can the driver somehow do something like
the soname is for libraries, e.g. increasing a serial number in the firmware
file names? This would make it possible to install several incompatible
versions in parallel.
Example: fwcutter unpacks such versions to
/lib/modules/firmware/b43.${ABIVERSION}
and the driver looks in the directories for whatever kinds of ABIVERSION are
supported by that version of the driver.

It was bad at the bcm43xx/bcm43xx_mac80211 time, but it's going to be a bigger annoyance this time, because the driver with the same name "b43" will need a different fwprefix for different kernel versions. I don't think modprobe.conf can be written to use different options for different kernel versions. And if it can, I don't want to force everyone to figure it out. The driver knows which firmware is needs. It's the driver's responsibility to express its requirements, rather that the users' responsibility to figure out which firmware this particular version of the driver wants. iwlwifi changed the firmware name when a different firmware was needed. And that's a good example, in my opinion. -- Regards, Pavel Roskin ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

b43 will need a firmware upgrade soon
The b43 driver will need an incompatible firmware upgrade, soon. I'm probably going to do this in 2.6.25 or 2.6.26. The update will require people to download and extract updated officially supported firmware. The firmware will be linked to from the usual place at linuxwireless.org. The driver will print a verbose error message when it detects too old firmware and abort initialization. This is needed in order to add support for new devices (N-PHY). Broadcom changed the ABI of the firmware, so we are forced to also change the ABI of the driver. I'm very sorry for the inconvenience. -- Greetings Michael. ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev
