Never understood why original init values are split in two files. Michael: SHM(0x0014) (16bit) is not used by the open source firmware, I know the b43 reads core revision from SHM(0x0016). Normally SHM(0x0014) is set to zero. We can put fw capabilities here (0x0014), e.g.: - bit 0: [0 state that encryption should be handled by b43] - bit 1: [0 state that qos is not supported] We can prepare a firmware image with such feature + watchdog. Posting ASAP with new initvals (less values). A question: is the standard kernel aware that date set to indicates an opensource firmware or some define should be activated on compilation?

Well, no. There's no known bug. But the PCMCIA core API is just crap. I had to fight with all those undocumented flags for a long time to get my card working. There might be some flag needed (or not) by your card that we don't set/clear, yet. SSB failing to switch the core indicates a very basic problem with the PCMCIA setup, because the coreswitch is the most basic and very first operation we do on the device. It's also done through PCMCIA config space registers, so it indicates your config space is not accessible. Which is a core failure. So I _guess_ it could probably be a bug somewhere in drivers/net/wireless/b43/pcmcia.c. However, of course, it can be everywhere. This file is just where I had the major problems to get the thing running. -- Greetings, Michael. ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

I like the idea of encoding the capabilities in the firmware as it would be a self-documenting method as the firmware evolves. Is using the Broadcom names for the firmware the best course of action? What if the opensource firmware files were named something like "os-ucode5.fw", etc. and b43 were coded to check for those files first? It would then fall back to the standard firmware if the opensource version is not found.

To make the driver detect the firmware as opensource, write 0x to SHM_UCODEDATE You need to disable the watchdog in b43_periodic_every15sec(), if you don't implement the watchdog mechanism in your firmware. But it's pretty easy to implement. It just has to write 0 to some register in the MAC loop. Of course, the register has to be unused in the rest of the code. -- Greetings, Michael. ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

Yes, please introduce a feature-bitfield at some location in SHM that's unused by the proprietary firmware. This bitfields would contain a bit for QoS and a bit for hwcrypto. Also change your firmware so the driver detects it as open-source firmware. I think that's done by writing 0x to the date/time field in SHM. I don't quite remember, but it's something like that. Note that this might mean that the firmware watchdog in the driver will trigger, as that's enabled by the open-source-firmware-flag. We might want to temporarly disable the watchdog in the driver for the time being. -- Greetings, Michael. ___ Bcm43xx-dev mailing list Bcm43xx-dev@lists.berlios.de https://lists.berlios.de/mailman/listinfo/bcm43xx-dev

Yes, but I think you should give them names, not just named array

Actually there are 2 ways to make firmware works: 1) Disable hw crypto with module parameter 2) Remove pcm5.fw from your /lib/firmware/b43 directory When I run the firmware I never include pcm5.fw file.
