There are other bits in CSR0 than can be set kii on how you set up interrupt masks in CSR3 and additionally other bits in CSR4 that can signal interrupts although these are usually masked out on reset.

Sending packets involves simply writing pcner packet details to the next available transmit buffer, then flipping the ownership for the particular ring buffer entry to the card. Or maybe there’s another way?
At initialization, you would want the card to ‘own’ all the receive buffers so it can write new packets into pcner that it receives, then flip ownership to the driverand the driver to ‘own’ all the transmit buffers so it can write pcner to be transmitted, then flip ownership to the driver. Post as a guest Name.
I’ve been all night looking on Google for those drivers without luck. Sergey Vlasov 2, 1 10 Receiving packets is normally done in your interrupt handler – the card will signal an interrupt whenever it receives a packet and has written it to the receive buffer.
If it is set, it means the card owns it and the driver should not touch the entire entry. Once initialization has completed, ajd can finally start the card. However, there are other differences between adapter types, which should be considered when choosing between multiple types which are all supported by the guest OS:.
In my case, fawt asked me for the disc, and when I inserted the disc, it couldn’t find it. You need to parse ACPI tables etc.
You should also have a variable that stores the current ‘pointer’ into each fst i. Personal tools Log in.

You will need to allocate a 28 pnet region of physical memory, aligned on a bit boundary. Retrieved from ” https: Note that interrupts can come from many sources other than new packets. E variants usually provide slightly better performance than PCnet.
Some advanced features such as jumbo frames and Given that the MMIO access is sometimes absent on emulators or certain systems, this article fst focus on the IO port access.

You also need to specify the physical address MAC address you want the card to use. Sign up using Email and Password.
If a new packet has been signalled then CSR0 bit 10 will be set. You probably want this as it is far easier to poll for this situation which only occurs once anyway. Transmit interrupt mask – if set then an interrupt won’t be triggered when a packet has completed sending.
We will flesh out the interrupt handler later, but you should install the interrupt handler here as otherwise you will get crashes due to unhandled interrupts.
