SqueakNOS-gera.32

Again, if anybody thinks it's too much to send this to the list, I'll stop doing it. Name: SqueakNOS-gera.32 Author: gera Time: 23 July 2006, 12:08:51 am UUID: 72271f05-9191-4ae2-b6a4-9c20fa5ab6d2 Ancestors: SqueakNOS-gera.31 Added NetworkingDevice as superclass for LancePCIDevice and Realtek8139Device. This class will have the structure for NetworkingDevices, for example, nextPacketPut: and nextPacket: with a SharedQueue for outgoing packets, and with knowledge pass the incoming packets up. I also think that the name of some methods can be stadarized across different implementations, for example #receiveInterruptPending, #handleReceiveIRQ, #missedPacketCounter, etc. Even when the specification for every card names them different.

SqueakNOS-gera.33: Realtek8139Device should be able to transmit packets

Name: SqueakNOS-gera.33 Author: gera Time: 23 July 2006, 3:08:10 am UUID: b2c87195-3e39-42b0-ac6d-1af7d53d0cf7 Ancestors: SqueakNOS-gera.32 Now the internal address of an ExternalIOPort is (realPortNumber - 1) so there's not so much stupid +/- 1. (remeber the overhead from previous commits? this is a small improvement) Realtek8139Device should be able to transmit packets now, although I have not tested it. I'll do it tomorrow, I'm going to sleep now. If you want to test it you can do the following (which will also work for a Lance device). If the destination IP address exists, you should see the answer in the Transcript. (this code has a fix from that in the Monticello commit) Realtek8139Device installOn: Computer current. "not needed for Lance" "easy accesors" netdev := Computer current defaultNetworkInterface. "Build EthernetPacket" eth := EthernetPacket new: 1000. eth source: netdev macAddress. eth destination: EthernetAddress broadcast. "Build ARPPacket (ARP Request)" arp := ARPPacket on: eth. eth type: arp class etherType. arp opcodeName: #Request. arp senderHardwareAddress: eth source. arp senderProtocolAddress: (InternetAddress fromString: '192.168.247.128'). arp targetProtocolAddress: (InternetAddress fromString: '192.168.247.1'). "send" netdev cheapSend: eth gera

Release 16-Jul-2006: Basic networking is working!

Javier Diaz-Reinoso dijo: > >/ I've tested now in a VirtualPC and worked ok! > / > Same here, however the mouse when move have "droppings" over the screen. > > This "dropping" are a problem of how the mouse cursor is drawn. When squeak runs on an operating system the cursor is normally handled by the system, however, here, we have to take care of that. And Squeak doesn't have nice hooks to know when it's going to draw to the screen, so hidding and showing the cursor again in the right moments is not trivial. However, this can (and must) be solved by touching a few methods in Squeak, so if anybody wants to give it a try and find a nice and clean solution, please, go ahead!!!! thanks for all the tests! I should start taking notes of all reports gera

Name: SqueakNOS-gera.30 Author: gera Time: 22 July 2006, 2:04:23 pm UUID: 0f18545a-3731-4d3a-8769-8cbb5c43e36f Ancestors: SqueakNOS-gera.29 first significant refactoring. MemoryHardwareDevice and PortHardwareDevice classes are gone. Now a HardwareDevice has a baseResource (either an ExternalAddress or an ExternalIOPort) which is used to access the resources. (delegation instead of different classes. This will let us build our Devices Hierarchy based on (external) functionality and not on (internal) structure. Added class ExternalIOPort pratially polimorphic with ExternalAddress. Everything was tested except for the Realtek8139Device, because for that I need to reboot :-) However the scheme is working, so everything should be fine.

Name: SqueakNOS-gera.29 Author: gera Time: 21 July 2006, 12:30:48 pm UUID: f90e893d-5544-4bf2-9ba7-8f08ab25acc0 Ancestors: SqueakNOS-gera.27 installOn: returns what has just been installed, so you can now do "aDeviceClass installOn: Computer current" and instapect it to start playing with it. This is fundamental for interactive OS development :-) Realtek8139PCIDevice is now (after 40 methods) perfectly receiving packets on IRQ using a full 64kb circular buffer. This is much better than what we now have for LancePCIDevice. This works boot my laptop natively (no vmware) !!!

I'm going to start to send this commit logs to the list, it anybody thinks this is no good, let me know. Now, a few of the latests. gera Name: SqueakNOS-gera.28 Author: gera Time: 18 July 2006, 8:24:35 pm UUID: 155ddbe2-fa73-4f85-ac79-88a4ab5ea692 Ancestors: SqueakNOS-gera.27 vendorsAndDevicesZLibData solved (hopefully). [initializer also fixed]

> Boot ok, but I don't get control about the image, the mouse nor > keyboard seems to respond. uhm... is it a ps/2 (or older) keyboard with a ps/2 mouse? if not, well... it won't work. Like USB mouse and keyboards are not supported yet :-( if not, try again, and don't touch anything until the Transcript stops moving (won't be too long). I'm not sure, but there may be some issues with keyboard events triggered before initialization is done. Let me know what happens, and thanks for testing! gera

*Marcus Denker said: *> Very cool... I just tried to run SqueakNOS on Paralles for Mac > (http://www.parallels.com/). > It works! (I have not tried networking, though). I don't think it'll work. I just looked it up, and the virtual ethernet card is an emulated RTL8029, and we are only supporting (now) the AMD Lance PCNet-32 cards (as supported by vmware). RTL8029 is the same card supported by qemu. I'm now working on the driver for RTL8139 (the 100MBits version of the RTL8029), however, the hardware is not compatible, so we'll need a different implementation. May be next? not sure, it's not too complicated... may be the first Device collaborated by someone else? :-) I just looked up what VirtualPC emulates, and it's a DEC 21140 adapter... I'm not sure how easy this one is. oh well... sorry about the lack of devices supported... we'll try to solve the problem with time :-) gera
