Re: [Bcm43xx-dev] crypto code
Hi!
..
bcm43xx: Could not generate tssi2dBm table
Ah, cool! :-)
ACPI: PCI interrupt for device :02:02.0 disabled
And that's the end of the story.
What is this tssi2dBm table?
Recently st3 added some code for dynamic generation of the tssi2dbm
table based on the paXbY values in sprom. (Ask some physician about
what this table is good for ;-) ) Your error indicates that the
specification for this function is still broken... shame on me! ;-)
Could you add some printk's to bcm43xx_read_sprom to print out all
paXbY (with X \in {0,1}, Y \in {0,1,2}) and send those values to me?
Sven

[Bcm43xx-dev] handle_irq_transmit_status() never called on iBook, Airport Extreme
I am running rev 991 on an iBook G4 (openfirmware id PowerBook6,5) and Airport Extreme. I can associate with the base station, but I obtain TX timeouts after the driver has transmitted approximately 410 packets, where 410 is 80% of the number of DMA slots (512). Upon further investigation, it appears that the function handle_irq_transmit_status() is never called, and therefore the driver never frees DMA slots in bcm43xx_dma_handle_xmitstatus(). Therefore, the driver suspends when reaching suspend_mark in request_slot() and never recovers. This behavior seems consistent with the reports of ``occasional'' TX timeouts by other people on this mailing list. I do observe bcm43xx_interrupt_handler() being invoked, but the ``reason'' variable never has the BCM43xx_IRQ_XMIT_STATUS set. I would appreciate if other people could confirm whether handle_irq_transmit_status() is called on their system, so that I can try to further diagnose the problem.

This code is untested and indeed likely to be wrong. I have no facilities to test it (neither has any other developer). Well, I do have a card with rev 5, so I can test it. On my machine, the code does invoke dma_rx() to read from rx_ring1, so at least this part is working. However, I always get len == 0 when (ring-mmio_base == BCM43xx_MMIO_DMA4_BASE), the packet is dropped, and the bcm43xx_rx_transmitstatus() mechanism is not invoked. Any suggestion? Ok, it should not be dropped. Afaik the len should be ignored on DMA4. (I can not check, as the specs server is down). But you may play around by yourself. Do a hack to ignore the len on DMA4 and pass the xmitstatus blob to bcm43xx_rx_transmitstatus(). The xmitstatus blob is at the beginning of the descriptor buffer (_no_ frame offset is used) and has a length of sizeof(struct bcm43xx_hwxmitstatus). So instead of doing: len = le16_to_cpu(rxhdr-frame_length); You might hack something like that: if (ring-mmio_base == BCM43xx_MMIO_DMA4_BASE) len = sizeof(struct bcm43xx_hwxmitstatus); else len = le16_to_cpu(rxhdr-frame_length); Please also do another thing. dump the xmitstatus blob, using bcm43xx_printk_dump() and post the hexdump here. Just to see if we actually receive sane data. -- Greetings Michael. pgpP8LV1pMy7v.pgp Description: PGP signature
Re: [Bcm43xx-dev] handle_irq_transmit_status() never called on iBook, Airport Extreme
This patch seems to do the trick. I am ignoring the bcm43xx_rx_transmitstatus() mechanism and calling bcm43xx_dma_handle_xmitstatus() directly. patch Description: Binary data
[Bcm43xx-dev] Support for BCM47XX (dscape branch)
Hi BCM43xx hackers.
I'm one of the OpenWrt developers and I'm currently working on
integrating your driver into our development branch. I've written a
patch which adds support for a BCM43xx core integrated into the main SB
of the BCM47xx SoC. It applies against the dscape branch, which I intend
to use, but it should be easy to port it to trunk. Some people on
irc.sipsolutions already reviewed an earlier version, so it would be
nice if you could commit this version to SVN.
While testing it, I was able to associate with another AP, but couldn't
transfer any data (had to hack some of the rate stuff for testing, this
might be the problem).
Have fun,
Felix
