Marvell Yukon ethernet and xVM

When xVM was integrated into Nevada in build 75, I immediately tried it on my laptop (a Toshiba M3). Only to find out that it didn't work because xVM requires GLD version 3 network drivers. My particular type of M3 unfortunately has a Marvell Yukon gigabit ethernet adapter and the skge driver from SysKonnect I had been using for the past years is not a GLD v3 driver.

While looking for a more recent version of skge (hoping for GLD v3 support in skge), I came across the myk driver written by Masayuki Murayama. This driver can be compiled as a GLD v3 driver and a quick look in the install script showed that the PCI ID of my Yukon chip was supported by myk. To compile a GLD v3 version of the driver you'll need the driver sources and a recent copy of the ON sources (for the required GLD header files).

$ gzcat myk-2.5.0.tar.gz | tar xf -
$ cd myk-2.5.0
$ rm Makefile.config
$ ln -s Makefile.config_gld3 Makefile.config
$ vi Makefile.config
Change -I to point to where you keep the ON sources:
#
# Common configuration infomations for all platforms
#
DRV     = myk
include version
DFLAGS  = -DDEBUG -DDEBUG_LEVEL=0 -DGEM_DEBUG_LEVEL=0 \\
          -DTX_BUF_SIZE=256 -DRX_BUF_SIZE=256 \\
          -I /export/home/ml93401/ws/onnv-gate/usr/src/uts/common  change appropriately
#
CFGFLAGS = -UCONFIG_OO \\
           -DGEM_CONFIG_POLLING \\
           -DGEM_CONFIG_VLAN -UCONFIG_HW_VLAN \\
           -DGEM_CONFIG_CKSUM_OFFLOAD \\
           -DGEM_CONFIG_GLDv3 -DSOLARIS10

LDFLAGS += -dy -N misc/mac -N drv/ip
Build and install the driver:
$ make
$ su
# ./adddrv.sh
After a reboot we should have a GLD v3 driver usable for xVM (if the type is not 'legacy' it is a GLD v3 driver):
# dladm show-link
myk0            type: non-vlan  mtu: 1500       device: myk0
iwi0            type: non-vlan  mtu: 1500       device: iwi0
Creating a DomU now works fine (as expected). If only I had more memory in this laptop...
