This is a call for testers for the Winbond W89C840F fast ethernet driver. The Winbond 840F is a tulip clone with a couple of wrinkles: the registers are spaced 4 bytes apart instead of 8 and the receive filter is programmed by writing directly to registers instead of loading a setup frame via the transmit DMA engine. The receive filter also has only one perfect address and a 64-bit multicast hash filter instead of a 16 entry perfect filter ans a 512-bit hash table. The driver source is available from the following locations: http://www.freebsd.org/~wpaul/Winbond/3.0 source for FreeBSD 3.0 http://www.freebsd.org/~wpaul/Winbond/2.2 source for FreeBSD 2.2.x To add the driver to an existing system, do the following: - Download the correct version of if_wb.c and if_wbreg.h for your version of FreeBSD. - Copy if_wb.c and if_wbreg.h to /sys/pci. - Edit /sys/conf/files and add a line that says: pci/if_wb.c optional wb device-driver - Edit your kernel config file (e.g. /sys/i386/conf/GENERIC) and add a line that says: device wb0 - Configure a and compile a new kernel and boot it. So far, the only card I've found that uses the Winbond chip is the Trendware TE100-PCIE (www.trendware.com). Trendware also makes DEC tulip and PNIC adapters. I believe Winbond may make their own cards with this chip as well. Note: - This is the W89C940F is _NOT_ The same as the W89C840F. The 940 is a 10Mbps only NE2000 clone. - The wb driver uses the same 'kludge descriptor' hack as the PNIC driver. I get the idea that the behavior I noticed with the PNIC is par for the course with tulip and tulip-like devices. I think reloading the transmit list base address register is only possible when the transmitter is in the 'stopped' state. Now I defy anybody to tell me how to put the transmitter in the 'stopped' state other than by resetting the chip. As usual, please report successes or failures to wpaul@skynet.ctr.columbia.edu. -Bill -- ============================================================================= -Bill Paul (212) 854-6020 | System Manager, Master of Unix-Fu Work: wpaul@ctr.columbia.edu | Center for Telecommunications Research Home: wpaul@skynet.ctr.columbia.edu | Columbia University, New York City ============================================================================= "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" ============================================================================= To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
