The patch is 600k large and available under: http://i2o.shadowconnect.com/patches/i2o-build_92.patch and also bzip2 compressed under: http://i2o.shadowconnect.com/patches/i2o-build_92.patch.bz2 The major benefits are: - sysfs support - PCI probing (which now should allow PCI hotplugging) - dynamically allocated request queues and gendisks for block devices and a own request queue per disk (which results in much better performance on many parallel requests) To verify the stability, we've run 4 parallel bonnie++ on a dual Opteron on 4 separate disks without a problem. To generate huge load we've also created a ext2 filesystem on all 4 disks in parallel. This lead to hangups of single disks in earlier versions, but is now fixed. Also the driver was tested on 32-bit as well, but only with 2 disks :-) Compared to my last post, all subsystems are now converted to use the new API. Please include the patch to get a wider exposure to test it, and let me know, if there is something missing or there is something to change. Any comment is appreciated.
