The changes I made are to the driver in -current, and the new code is at: http://www.freebsd.org/~wpaul/SiS/busdma I have tested this driver on FreeBSD/x86 using a NatSemi DP83815 card (the Netgear FA312TX) and it seems to work fine for me. However, I'm not 100% certain I used the busdma API properly in all cases. If anyone with a busdma clue would care to look over the code and see everything looks more or less legal, I would appreciate it. My main concern is that I'm using bus_dma_load() and bus_dma_unload() correctly (i.e. such that I'm not leaking any resources). Unless anyone raises serious objections, I would like to commit this code ASAP (the last test I really need to do is make sure it works correctly on an alpha). -Bill ============================================================================= -Bill Paul (510) 749-2329 | Senior Engineer, Master of Unix-Fu wpaul@windriver.com | Wind River Systems ============================================================================= "I like zees guys.
