[LinuxBIOS] question about via...

[LinuxBIOS] SLIT Support

Kenji Noguchi

3:34 a.m.

Attached is a patch for TeleVideo TC7020 support. It should work fine with r2993. Please kindly review.

Large part of the patch is just a duplicate of BCOM Winnet100 patch hence many files retain copyright holder as Juergen Beisert.

My TC7020 runs Debian's unmodified kernel 2.6.18, and mount /var /home /root and /tmp on /dev/shm/{var,home,root,tmp} so that the Compact Flash drive remains read-only. No worries of wear and tear, and clean shutdown.

I will see how MythTV performs on this box. DirectFB already runs nicely. Does anyone know if GX1 MPEG decoder is supported by video4linux?

Regards, Kenji Noguchi

p.s. Sorry Uwe that I missed your email asking for the status.

Would someone review my patch? http://www.linuxbios.org/pipermail/linuxbios/attachments/20071129/c76bd0ef/a... By the way why the URL for attachments got .dll in extension? It triggers antivirus softwares...

Thanks, Kenji

Thanks, see quick review below:

Can you document this in the wiki (kernel command line options etc).

...

Dunno, sorry. Juergen?

Oh, if you can, please check the Wake-on-LAN functionality on this board (with vendor BIOS and LinuxBIOS). On the BCOM Winnet100 we're lucky, it works out of the box! Seems to be implemented completely in hardware on that board, so no LinuxBIOS code needed...

I think this is wrong, here's the lspci you posted a while ago:

The 0f.0 line should be removed here.

...

```
 device pci 12.0 on		# ISA bridge
```

   chip superio/nsc/pc97317	# Super I/O

Can you run the latest version of 'superiotool -dV' on the board (with the vendor BIOS)? I this really a PC97317 on your board, too?

...

     device pnp 2e.0 on		# PS/2 keyboard

```
       io 0x60 = 0x60
```
```
       io 0x62 = 0x64

```
       io 0x60 = 0x70
```
```
       irq 0x70 = 8
```
```
     end
```

     device pnp 2e.3 off		# Floppy (N/A on this board)

Does your board have a floppy connector?

...

```
       io 0x60 = 0x3f0
```
```
       irq 0x70 = 6
```
```
       drq 0x74 = 2
```
```
     end
```

     device pnp 2e.4 on		# Parallel port

```
       io 0x60 = 0x378
```
```
       irq 0x70 = 7
```
```
     end
```

     device pnp 2e.5 on		# COM2 (used for smartcard reader)

COM2 doesn't seem to be connected to a smartcard reader on your board, looks like a normal serial port (from the manual). Correct?

...

```
       io 0x60 = 0x2f8
```
```
       irq 0x70 = 3
```
```
     end
```
```
     device pnp 2e.6 on		# COM1
```
```
       io 0x60 = 0x3f8
```
```
       irq 0x70 = 4
```
```
     end
```
```
     device pnp 2e.7 on		# GPIO
```
```
       io 0x60 = 0xe0
```
```
     end
```

     device pnp 2e.8 on		# Power management

```
       io 0x60 = 0xe8
```
```
     end
```
```
   end
```
```
 end
```
```

```
 device pci 12.2 on end		# IDE
```
```
 device pci 12.3 on end		# Audio
```

 device pci 12.4 on end		# VGA (onboard)

```
 device pci 13.0 on end		# USB
```

Maybe add this here:

device pci 15.0 on end # Ethernet (onboard)

Can you confirm that this device is an onboard NIC?

...

```
 register "ide0_enable" = "1"
```

 register "ide1_enable" = "0"	# Not available/needed on this board

I assume there's one IDE connector on the board, correct? If you have two (or none?) you could change these values here.

You don't have a 14.0 PCI device in your lspci, are you sure this last line should be here?

Not sure about this part, please check the patch with subject '[LinuxBIOS] [PATH] irq routing on cs5530a/cs5536' which probably does similar things.

I haven't yet had the time to review it. Can you confirm that dropping the above code and using that patch works fine? I think we should apply the patch, but this needs a bit of testing as it effects all GX1 boards.

After the patch is in svn, all PIRQ stuff should be in irq_tables.c only IMO.
