Re: [Linux-gpib-general] New GPIO adapter / Patch submission guide?

Dear Michael, bb_DAV_interrupt(): the check for buffer overflow is at line 390 of current version [76c3dc] (line 379 of last unpatched [b4cbd1]): priv->end_flag = ((priv->count >= priv->request) || priv->end); 'count' is the number of read character; 'request' is the buffer length; when the buffer is full, the operation is terminated even before an EOI or newline. Can you reproduce the conditions when this mechanism does not work correctly? system hang: yes, there is a problem; when you address a non existing device with ibrd(), you correctly obtain a timeout error; when you try an ibwrt() on a non existing device, the system hangs. I shall try to spot the error and propose a remedy asap. bye Marcello Carla' On 7/21/24 15:51, Michael Schwingen wrote: > Hi, > > it seems my mail server blocked your replies, so i have to pick this from > the archive, breaking the references - sorry for that. > >> We have no guidelines for submitting patches, we are very flexible. >> Smaller patches are of course preferred. > OK.
