2006-05-08[PATCH] USBATM: change the default speedtouch iso altsettingDuncan Sands
The maximum possible bandwidth for a speedtouch modem is about 7Mbaud. You can only get this by using isochronous urbs (enable_isoc=1) and altsetting 3. With the current default altsetting of 2, the modem maxes out at about 4Mbaud. So change the default altsetting to 3 when using isochronous urbs. It would be nice to base the altsetting on the detected line speed, but that's hard given the current design.

2006-01-31[PATCH] USBATM: allow isochronous transferDuncan Sands
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).

2006-01-31[PATCH] USBATM: measure buffer size in bytes; force valid sizesDuncan Sands
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 <baldrick@free.fr> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2006-01-31[PATCH] USBATM: add flags fieldDuncan Sands
Have minidrivers and the core signal special requirements using a flags field in struct usbatm_data. For the moment this is only used to replace the need_heavy_init bind parameter, but there'll be new flags in later patches.

2006-01-10[PATCH] turn "const static" into "static const"Jesper Juhl
ICC likes to complain about storage class not being first, GCC doesn't care much (except for cases like "inline static"). have a hard time seeing how it could break anything. Thanks to Gabriel A. Devenyi for pointing out http://linuxicc.sourceforge.net/ which is what made me create this patch.

2005-07-12[PATCH] USB ATM: fix line resync logicDuncan Sands
We map states 0x00 and 0x10 to the ATM_PHY_SIG_LOST flag. The current logic fails to resync the line if we get state 0x10 followed by 0x00, since we only resync the line when the state is 0x00 and the flag changed. Doubly fixed by (1) always resyncing the line when the state is 0x00 even if the state didn't change, and (2) keeping track of the last state, not just the flag. We do (2) as well as (1) in order to get better log messages. This is a tweaked version of the original patch by Aurelio Arroyo.

Port the speedtch driver to the new usbatm core.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
