[PATCH] UEAGLE : cmv name bug (was cosmetic)

2006-02-01T01:23:41+00:00

this patch correct a possible bug with cmv_name being static. If there is 2 modems and the driver is scheduled when filling cmv_name this could result with garbage in cmv_name. We allocate cmv_name on the stack but with a small size in order to avoid that. Signed-off-by: Matthieu CASTET Signed-off-by: Greg Kroah-Hartman

[PATCH] UEAGLE : add iso support

2006-02-01T01:23:40+00:00

This patch adds the support for isochronous pipe. A new module parameter is added to select iso mode. It is set to iso by default because bulk mode doesn't work well at high speed rate (>3 Mbps for upload). We use UDSL_IGNORE_EILSEQ flags because ADI firmware doesn't reply to ISO IN when it has nothing to send [1]. [1] from cypress datasheet : The ISOSEND0 Bit (bit 7 in the USBPAIR Register) is used when the EZ-USB FX chip receives an isochronous IN token while the IN FIFO is empty. If ISOSEND0=0 (the default value), the USB core does not respond to the IN token. If ISOSEND0=1, the USB core sends a zero-length data packet in response to the IN token. The action to take depends on the overall system design. The ISOSEND0 Bit applies to all of the isochronous IN endpoints, IN-8 through IN-15.

[PATCH] USBATM: semaphore to mutex conversion

2006-02-01T01:23:40+00:00

This is the usbatm part of the Arjan, Jes and Ingo mass semaphore to mutex conversion, reworked to apply on top of the patches I just sent to you. This time, with correct attribution and signed-off lines. Signed-off-by: Arjan van de Ven Signed-off-by: Ingo Molnar Signed-off-by: Duncan Sands Signed-off-by: Greg Kroah-Hartman

[PATCH] USBATM: -EILSEQ workaround

2006-02-01T01:23:40+00:00

Don't throttle on -EILSEQ urb status if requested by a minidriver. It seems the ueagle modems are buggy, giving -EILSEQ when they have no data to send. The ueagle change will be sent separately by the ueagle guys. Patch by Matthieu Castet. Signed-off-by: Duncan Sands Signed-off-by: Greg Kroah-Hartman

[PATCH] USBATM: handle urbs containing partial cells

2006-02-01T01:23:40+00:00

The receive logic has always assumed that urbs contain an integral number of ATM cells, which is a bit naughty, though it never caused any problems with bulk transfers. Isochronous urbs spank us soundly for this. Fixed thanks to this patch, mostly by Stanislaw Gruszka. Signed-off-by: Duncan Sands Signed-off-by: Greg Kroah-Hartman

[PATCH] USBATM: allow isochronous transfer

2006-02-01T01:23:40+00:00

While the usbatm core has had some support for using isoc urbs for some time, there was no way for users to turn it on. While use of isoc transfer should still be considered experimental, it now works well enough to let users turn it on. Minidrivers signal to the core that they want to use isoc transfer by setting the new UDSL_USE_ISOC flag. The speedtch minidriver gets a new module parameter enable_isoc (defaults to false), plus some logic that checks for the existence of an isoc receive endpoint (not all speedtouch modems have one).

[PATCH] USBATM: measure buffer size in bytes; force valid sizes

2006-02-01T01:23:40+00:00

Change the module parameters rcv_buf_size and snd_buf_size to specify buffer sizes in bytes rather than ATM cells. Since there is some danger that users may not notice this change, the parameters are renamed to rcv_buf_bytes etc. The transmit buffer needs to be a multiple of the ATM cell size in length, while the receive buffer should be a multiple of the endpoint maxpacket size (this wasn't enforced before, which causes trouble with isochronous transfers), so enforce these restrictions. Now that the usbatm probe method inspects the endpoint maxpacket size, minidriver bind routines need to set the correct alternate setting for the interface in their bind routine. This is the reason for the speedtch changes. Signed-off-by: Duncan Sands Signed-off-by: Greg Kroah-Hartman

[PATCH] USBATM: use dev_kfree_skb_any rather than dev_kfree_skb

2006-02-01T01:23:40+00:00

In one spot (usbatm_cancel_send) we were calling dev_kfree_skb with irqs disabled. This mistake is just too easy to make, so systematically use dev_kfree_skb_any rather than dev_kfree_skb. Signed-off-by: Duncan Sands Signed-off-by: Greg Kroah-Hartman
