I believe the ICH7 is the host: chip=0x2e308086 so device ID is 2e30.

The current code looks for the Low Pin Count device at bus 0, device 31, function 0. This is where GPIO lives. My read is that the device ID is 0x27b8, sub type 8086.
Linux file /usr/share/misc/pci.ids lists:
27b8 82801GB/GR (ICH7 Family) LPC Interface Bridge
8086 544e DeskTop Board D945GTPI'll read the ICH7 spec to find out more. Next, we'll have to figure out the exact GPIO pin for Armed/Disarmed.
-
I agree, that's the LPC device.
After extensive testing I am thinking that the arm/disarm led on the XTM 5 is not driven by GPIO pins on the ICH7.As other models the GPIO base address is stored in LPC pci config at offset 48H: [2.0.1-RELEASE][root@pfSense.localdomain]/root(14): pciconf -r pci0:0:31:0: 0x48 00000481 As before bit 1 is hard wired high so the GPIO base is 0x0480\.

Or maybe the led is damaged on my box.
Next possibility is via the superIO chip but that is way harder to test. :(Steve

Or possibly it's driven from the LCD module in some way.
There is a clue in the boot message from the Watchguard OS:Parallel LCM Driver Version 0.0.2 is loaded plcm_drv: LPTx Address = 378 Logical Device GPIO2 disabled, no function, enabling now GPIO2(bit4) not configured for LED triggering, configuring now SST_ | <enable_flash_ich_dc_spi> WARNING: SPI Configuration Lockdown activated.</enable_flash_ich_dc_spi>
Hmm. Time to look at the display.

There is a clue in the boot message from the Watchguard OS:
GPIO2(bit4) not configured for LED triggering, configuring now
How about this GPIO 2 area? It is at gpiobase + 0x30. Section 10.10.6 in the spec. Bet you it is bit 4 does stuff…
-
If you mean GPIOs 32-63 on the ICH7 then I already tried that, see test results above. Nothing doing.
The fact that is refer to 'logical device gpio2' makes me think it could be the superio chip as that is how it is referred to in the datasheet. Also gpio2 bit 4 happens to be a dedicated gpio.
There is the other winbond chip which looks to be only accessible via i2c. That would be difficult.
Steve
-
Aha! ;D
Found it!
The arm/disarm led is controlled by bits 4 and 5 of logical device 8 (GPIO2) on the SuperIO chip.In order to use the led two things must first be set. The GPIO2 device must be enabled by setting CR30 on logical device 8 to 0x01. Then bits 4 and 5 must be set to output but setting CRF0 on logical device 8 to 0xCF. This ties in with the clue in the previous post.
The odd thing about this is that I would have expected these to be setup by the bios and set the LED as red from the outset. In fact my box never shows red at all if I boot the Watchguard OS.Then the led can be controlled via CRF1:
Control Register F1 Bit5 Bit4 Arm/Disarm LED 0x00 0 0 Off 0x10 0 1 Green 0x20 1 0 Red 0x30 1 1 Off
Accessing these control registers is a proper PITA! A great string of commands have to be sent. For example, setting CRF1 to 0x10 to set the led green:
[2.0.1-RELEASE][root@pfSense.localdomain]/conf(85): ./writeio 2e 87 Setting 2e to 87 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(86): ./writeio 2e 87 Setting 2e to 87 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(87): ./writeio 2e 7 Setting 2e to 7 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(88): ./writeio 2f 8 Setting 2f to 8 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(89): ./writeio 2e f1 Setting 2e to f1 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(90): ./writeio 2f 10 Setting 2f to 10 [2.0.1-RELEASE][root@pfSense.localdomain]/conf(91): ./writeio 2e aa Setting 2e to aa
Fortunately you can use superiotool to read back what we have done:

Unfortunately I think that's going to cause a conflict with the existing codes. :-\

There seemed to be quite a lot of potential in this box for unlocking additional features in the bios, boot from USB various power saving tweaks etc. Also the arm/disarm led is not correctly set to red at boot. I suspect that Watchguard must have fixed this with bios update them selves but I have no proof of that.
You can easily read and write the bios flash chip from pfSense with the flashrom package:pkg_add -r ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/i386/packages-8.1-release/Latest/flashrom.tbz
Initially I read the bios image to a file so I could look at it with various tools. This was all mostly new to me, I have played around with award bios mods before but not AMI. Much reading later I realised the bios is locked down because the 'user access level' is set to 2, 'limited', in which the only thing that can be modified by the normal user is the time and date.
As a first test I changed the access level to 3, full, using amibcp. Although I had read that newer AMI bioses could be corrupted by amibcp this did not seem to be the case for this one modification. I got brave and flashed back the modified image, success! I now had access to all the available settings.However many of the interesting settings are hidden in the standard bios so in order to enable USB boot I modified the bios image again to unhide most options. I chose to hide the LAN bypass menu since that relays are not included on the board. I reflashed the image, disaster! ??? It appears that, as reported on many other sites, amibcp does indeed often or almost always corrupt the bios. The first time I had just been lucky. Since the bios flash chip is soldered to the board there is no possibility for a 'hot flash' and I only have one of these anyway.
Looking on the positive side the board does have an SPI header next to bios chip for programming it and this seemed like an excellent opportunity to learn how to use it! ::)
Much reading later… I came across the website of this genius from the Czech republic. As well as providing a useful, and incredibly simple, circuit this man has provided code to the flashrom project to use it. Alternatively use his own code from DOS. Awesome job!
Now unfortunately you need a later version of flashrom than 8.1 provides but fortunately the most recent version from 8-stable installs and runs fine on an 8.1 box (for parallel port use anyway).Lanner helpfully provide the pinout of the SPI header but you can easily find it with a multimeter anyway. Interestingly the WP (write protect) pin is not connected which I thought was going to be a show stopper
but it's not needed. Also useful is that the motherboard, when plugged in but not powered up, provides the required 3.3V to power the chip pull the HOLD pin high. So some soldering and five minutes crossing my fingers later I'm back in business. :)
You don't want to be doing this but it's nice to know you can if you have to! :)Steve
-
How's the progress on these units? If you need help getting the LCD working, I have a hacky script that should work. And do you think any more will be hitting the second-hand market anytime soon? They seem okay on specs, but I guess Watchguard will EOL them anyways at some point.
-
The LCD is configured exactly the same as the previous models so existing drivers work fine.
The EOL on these is not going to be for a long time (sometime after 2016) so right now you just have to get lucky. ;)I have been playing around with a Core2Duo E4500. First of all it works in there no problems, it's detected by the bios and by pfSense. It's a nice upgrade from single core Celeron to Dual core C2D and it's not expensive. The platform should support many other processors. The peak power consumption goes up, 41W in the bios and around 47W while booting, but the idle consumption is identical at 30W so the fans remain slow unless it's pushed.
There is potential to actually reduce this by using Speedstep which is in the C2D but not the Celeron. However the required components are not all there. I think I'm about 90% of the way to making it work but something is eluding me.
So far I have:
Extracted and modified the DSDT table from the bios (including fixing a few errors on the way) to include code to pass the P-state information to the est(4) driver via ACPI.
Found and disabled the code that sets the EIST lock bit in the bios. This required extracting the relevant bios module and disassembling it.
Set the EIST enable bit. Both these are MSRs in the CPU.So far the est driver attaches to the 2 cpus at boot and provides the various frequency/voltage combinations to powerd. Everything appears to be working great except that the power consumtion remains steadily at 30W. I don't think it's actually changing anything. :-\
I'm learning a lot though! :)

Oh, so the SDECLCD firebox driver works pretty much out of the box with these units? That makes life pretty easy. It looked different in your pics, but I would assume Watchguard made them make it the same for ease of use.
-
Exactly. Only the the X-Core had an actual SDEC LCD all the other models have LCDs made by someone else but with custom part numbers. I assumed Watchguard didn't want to have to include code for many types of LCD in their OS.

I have been playing around with a Core2Duo E4500.
Wikipedia mentions that series has 64bit support.
We need to put a 64 bit lcdproc/sdeclcd package on the radar…
-
Indeed, though I'm running it 32bit. It would be interesting to see whether there's much advantage to running 64bit. There are plenty of reports that it makes almost no difference.
I haven't tried your new driver yet but thanks for doing it :). Still trying to make EIST function correctly. It doesn't help that the SuperIO is not compatible with mbmon so I can't read the core voltage directly.Steve
-
I'd love to get the lcdproc-dev and SDECLCD driver working on 64bit. Does that require a whole driver rewrite or a recompile? I'm not even sure if lcdproc-dev is amd64 capable…

I think I'm losing my mind over EIST. ::)
I have eventually come to the conclusion that EIST is in fact working with my modified bios and loading a custom DSDT.[2.0.1-RELEASE][root@pfSense.localdomain]/root(1): sysctl dev.cpu dev.cpu.0.%desc: ACPI CPU dev.cpu.0.%driver: cpu dev.cpu.0.%location: handle=\_PR_.CPU0 dev.cpu.0.%pnpinfo: _HID=none _UID=0 dev.cpu.0.%parent: acpi0 dev.cpu.0.temperature: 25.0C dev.cpu.0.cx_supported: C1/1 C2/96 dev.cpu.0.cx_lowest: C1 dev.cpu.0.cx_usage: 100.00% 0.00% last 5000us dev.cpu.0.freq: 1200 dev.cpu.0.freq_levels: 2200/65000 2000/55000 1800/50000 1600/45000 1400/40000 1200/30000 dev.cpu.1.%desc: ACPI CPU dev.cpu.1.%driver: cpu dev.cpu.1.%location: handle=\_PR_.CPU1 dev.cpu.1.%pnpinfo: _HID=none _UID=0 dev.cpu.1.%parent: acpi0 dev.cpu.1.temperature: 25.0C dev.cpu.1.cx_supported: C1/1 C2/96 dev.cpu.1.cx_lowest: C1 dev.cpu.1.cx_usage: 100.00% 0.00% last 5000us
If I read the MSRs directly from the CPU using cpucontrol I can see that the multiplier and VID are set as requested by the DSDT.
[2.0.1-RELEASE][root@pfSense.localdomain]/root(3): cpucontrol -m 198 /dev/cpuctl0 MSR 0x198: 0x0b280b28 0x0600061d
As well as that I can see the core voltage is reduced by reading the SuperIO chip registers directly.

However it is almost impossible to see any effect because the CPU supports C1/E state which is already as low power if not lower. In fact I believe that EIST will only operate in C0 anyway. It will probably reduce the total power consumption when the box is under a moderate load since it can only enter C1 when the CPU is idle for a time.
Unfortunately the minimum core voltage either for C1/E or the lowest EIST P-state is VID=1D (decimal 29) which is 1.19V. I'm not sure if that's just because my CPU is bad quality or that's a MB limitation. The full speed core voltage is 1.325V but the spec is down to 0.85V :-\ (or 0.962 depending where you look)
It doesn't seem to support SLFM (Dymnamic FSB) either, or at least I can't seem to trigger it, which would otherwise enable a lower core voltage.
You might think that reducing the CPU frequency would have a measurable effect on the power draw. :-
Disappointing in some ways since using EIST on the Core-E box reduced the power consumption and CPU temps quite a bit.I've been staring at register values in hex for so long now I'm starting to dream about it! ;)
If you want to know about EIST and such just read this:

It has almost all the information I found on many other sites in one article. :)Steve

I'd love to get the lcdproc-dev and SDECLCD driver working on 64bit. Does that require a whole driver rewrite or a recompile? I'm not even sure if lcdproc-dev is amd64 capable…
amd64 is one of the supported architectures for lcdproc as a project, so I would not expect problems there. The sdec driver, though, has never been compiled, much less run, in that arch. If/when someone manages to run a 64bit OS on this box, I'll be happy to provide a binary for testing. Just need to download/install a 64bit FreeBSD virtual machine, and recompile.

I have hardware from Watchguards OEM (Lanner calls it thier LCM) that uses the same screen and is 64bit. I'd be more than willing to try out any binaries you need tested. Only differences is that the screen on my units are 20x2 and not 16x2. I'm sure that really isn't an issue tho. Currently the 32bit SDECLCD works fine, except the screens don't seem to use the full 20x2, although the "Next|Prev" popups show in the extra characters so they work.
Let me know what you need done/tested. I assume what works for me will work perfectly on stephen's unit.
