2007-06-01potential parse error in ifdefYoann Padioleau
I have made a tool to parse the kernel that does not pre-process the source. That means that my parser tries to parse all the code, including code in the #else branch or code that is not often compiled because the driver is not very used (or not used at all). So, my parser sometimes reports parse error not originally detected by gcc. Here is my (first) patch.

2006-10-25[SCSI] aic79xx: Fixup external device resetHannes Reinecke
Whenever an external device is resetted we really have to take care to keep the channel in sync. Just notifying SCSI-ML and retry is not enough as we have to make sure the SCSI bus is not getting confused, either. So whenever we detect an external reset we rewrite the command to TUR, disable packetized command and notify the internal engine that an abort has happened. This way we trigger a proper bus reset sequence and all devices will be renegotiated properly. Kudos to Justin Gibbs and Luben Tuikov for this idea.

2006-06-26[SCSI] aic79xx: remove slave_destroyHannes Reinecke
Even with the latest fixes aic79xx still occasionally triggers the BUG_ON in slave_destroy. Rather than trying to figure out the various levels of interaction here I've decided to remove the callback altogether. The primary reason for the slave_alloc / slave_destroy is to keep an index of pointers to the sdevs associated with a given target. However, by changing the arguments to the affected functions slightly it's possible to avoid the use of that index entirely. The only performance penalty we'll incur is in writing the information for /proc/scsi/XXX, as we'll have to recurse over all available sdevs to find the correct ones. But I doubt that reading from /proc is in any way time-critical. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-04-13[SCSI] aic79xx: target hotplug fixesHannes Reinecke
When a target is added aic79xx tries to be overly clever: it changes the command on the fly to TEST UNIT READY and tries to requeue the original command. Sadly this breaks SCSI compability and of course the midlayer is getting a bit confused by it. So we're just removing that bit of code and let the midlayer deal with it. It's clever enough by now. And the driver code is getting simpler. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-04-13[SCSI] aic79xx bus reset updateHannes Reinecke
As James B. correctly noted, ahd_reset_channel() in ahd_linux_bus_reset() should be protected by ahd_lock(). However, the main reason for not doing so was a deadlock with the interesting polling mechanism to detect the end a bus reset. This patch replaces the polling mechanism with a saner signalling via flags; it also gives us the benefit of detecting any multiple calls to ahd_reset_channel().

2006-03-12[SCSI] aic79xx: Invalid Sequencer interrupt occuredHannes Reinecke
On certain systems the driver seems to hit upon some "scsi0: Invalid Sequencer interrupt occurred." problem and dumps card state. According to Adaptec engineers this message is harmless. So as not to confuse user we can as well disable the internal card state dump and just print out the message itself.

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!
