			=== lcd4linux ===


			To get the PicoLCD to work with Solaris, and ZFS we need '''/etc/lcd4linux.conf''' as well as the main '''lcd4linux''' binary. But before that will work we need to attach the '''ugen''' device to the USB node.

			To do this we need to pull out the device info from prtconf:

			prtconf -v
			name='usb-product-name' type=string items=1
			value='USB-LCD-256x64'
			name='usb-vendor-name' type=string items=1
			value='ITUNER INC'
			name='compatible' type=string items=9
			value='usb4d8,c002.2' + '''usb4d8,c002''' + 'usbif4d8,class3.0.0' + 'usbif4d8,class3.0' + 'usbif4d8,class3' + 'usbif,class3.0.0' + 'usbif,class3.0' + 'usbif,class3' + 'usb,device'

			/usr/sbin/update_drv -a -i '"usb4d8,c002"' ugen

			this attaches the ugen device to the LCD panel.


			When I compiled the PicoLCD version of lcd4linux on my Solaris server I used the following configure line:

			./configure --with-drivers=picoLCDGraphic,X11 --with-plugins=button_exec,cpuinfo,exec,fifo,file,uptime,loadavg,statfs,netdev,diskstats,uname,meminfo LIBS=-lkstat

			Technically the '''X11''' driver is not required, it was just helpful when I was porting over the various plugins (so I didn't have to sit next to the LCD to test it).

			During the porting work of lcd4linux, technically there are some changes required to the autoconf file '''configure.ac''' which I did not do. These include:

			test define
			kstat_open in libkstat LIBS=-lkstat
			kstat.h HAVE_KSTAT_H
			statvfs.h HAVE_STATVFS
			statfs.h HAVE_STATFS
			ctype.h HAVE_CTYPE_H
			/proc/uptime HAVE_PROC_UPTIME
			/proc/net/dev HAVE_PROC_NET_DEV
			/proc/meminfo HAVE_PROC_MEMINFO
			/proc/diskstats HAVE_PROC_DISKSTATS
			getloadavg() HAVE_GETLOADAVG
			strcasestr() HAVE_STRCASESTR
			linux/sem.h _SEM_SEMUN_UNDEFINED

			The last one has reverse logic, which could probably be changed, but either way on Solaris, we need to add in the "union semun" for it to compile.

			There are some issues in the porting that I did. For example, if you happen to be on a System with '''both /proc/net/dev and kstat.h''' it will not go well. This is trivial to fix though, if needed.

			Now as for the Solaris porting, I initially tried to emulate the Linux values as much as possible, but near the end added the useful Solaris bits as well. So as it is now, not all things are supported, and some new information exist.

			diskstats(reads, '''read_bytes''', read_sectors, writes, '''write_bytes''', write_sectors) - but the '''sectors''' value is the same as '''reads/writes'''. All other fields are 0.
			meminfo(MemTotal, MemFree) - All other fields are 0. But tempted to add Swap fields.
			netdev(Rx_bytes Rx_packets Tx_bytes Tx_packets) - All other fields are 0.
			statfs(*) - For some reason needs "/ 256" on ZFS filesystems to report correct values.


			The Solaris patch against are here

			[http://www.lundman.net/ftp/lcd4linux-lundman-patch1 lcd4linux-lundman-patch1] First patch.

			My GENERIC lcd4linux.conf changes are here:

			Widget HDDTemp {
			+ expression 'IDE Temp'.exec ('/usr/bin/hd hd -e c0t0\|grep "194 Temperature"\|sed "s\|[^ ]* [^ ] [^ ] [^ ] [^ ] \([^/]\)/.*\|\1\|"', 1000)

			Widget IDEIn {
			+ expression (diskstats('sd2', 'read_bytes', 500))/1024/1024

			+Widget IDEOut {
			+ expression (diskstats('sd2', 'write_bytes', 500))/1024/1024

			+Widget ETHIn {
			+ expression (netdev('e1000g1', 'Tx_bytes', 500))/1024

			+Widget ETHOut {
			+ expression (netdev('e1000g1', 'Rx_bytes', 500))/1024

			For example.


			New commands:

			I am also tempted to add a few Solaris specific commands. For example '''zpool''' stats for disk usage instead of statfs, but also '''zpool iostat''' for reads/writes which is much interesting that diskstat() for an individual disk.

== pico LCD ==

The picoLCD I purchased is ther 256x64 CDROM bay LCD panel. This means if I were to use good old C64 8x8 fonts, that I have a 32x8 display panel.
