2007-01-23[IrDA]: irda-usb TX path optimization (was Re: IrDA spams logfiles - since ↵Samuel Ortiz
2.6.19) Since we stop using dev_alloc_skb on the IrDA TX frame, we constantly run into the case of the skb headroom being 0, and thus we call skb_cow for every IrDA TX frame. This patch uses a local buffer and memcpy the skb to it, saving us a kmalloc for each of those IrDA TX frames. Signed-off-by: Samuel Ortiz <samuel@sortiz.org> Signed-off-by: David S.

2006-06-17[IRDA]: irda-usb.c: STIR421x cleanupsNick Fedchik
This cleans the STIR421x part of the irda-usb code. We also no longer try to load all existing firmwares but only the matching one (according to the USB id we get from the dongle).

2006-04-09[IRDA]: Support for Sigmatel STIR421x chipSamuel Ortiz
This patch enables support for the Sigmatel's STIR421x IrDA chip. Once patched with Sigmatel's firmware, this chip "almost" follows the USB-IrDA spec. Thus this patch is against irda-usb.[ch]. The code has been tested by Nick Fedchik on an STIR4210 chipset based dongle. Signed-off-by: Samuel Ortiz <samuel.ortiz@nokia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-02-19[IRDA]: irda-usb bug fixesJean Tourrilhes
This patch fixes 2 bugs in the USB-IrDA code. The first one is a buffer overrun in the RX path. We are now using IRDA_SKB_MAX_MTU when initializing the Rx URB. The second one is a potential stack recursion when unplugging the USB dongle. It seems that first we get the Rx URB with a generic error code, and after a while the Rx URB comes again with a "disconnect" error code. Since we are resubmitting the Rx URB immediately after receiving the first error one, we might enter an endless loop. When getting an error Rx URB, the patch defers the Rx URB resubmitting so that it gives us a chance to catch the disconnect one, in case the dongle has juts been unplugged. Tested against 2.6.16-rc2.

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!
