PCI TO NUBUS BRIDGE DRIVER
No idea what OS the pci to nubus bridge might support as of yet. Lots of suggestions already from Mr. Take a look of the interface card ships. Is this an actual device or is it something my laptop is hallucinating? Posted 16 July - PM That's Joined: Dec 21 - Re: Nubus USB?

Minicomputers, starting with the PDP-8were made of multiple cards, all powered by and communicating through a passive pci to nubus bridge.

The first commercial microcomputer to feature expansion slots was the Micral Nin Posted 16 July - PM Please perform the following, so that we can get the exact specs of your computer. This will better assist us in helping you more. In a delayed transaction, the target records the transaction including the write data internally and aborts asserts STOP rather than TRDY the first data phase. The initiator must retry exactly the same transaction later. In the interim, the target internally performs the transaction, and waits for the retried transaction. When the retried transaction is seen, the buffered result is delivered. A device may be the target of other transactions while completing one delayed transaction; it must remember the transaction type, address, byte selects and if a write data value, and only complete the correct transaction.
If the target has a limit on the number of delayed transactions that it can record internally simple targets may impose a limit of 1it will force those transactions to retry without recording them. They will be dealt with when the current delayed transaction is completed. If two initiators attempt the same transaction, a delayed transaction begun by one may have its result delivered to the other; this is harmless. The latter should never happen in pci to nubus bridge operation, but it prevents a deadlock of the whole bus if one initiator is reset or malfunctions. The PCI standard permits multiple independent PCI buses to be connected by bus bridges that will forward operations on one bus to another when required.
Generally, when a bus bridge sees a transaction on one bus that must be forwarded to the other, the original transaction must wait until the forwarded transaction completes before a result is ready. One notable exception occurs in the case of memory writes. Pci to nubus bridge, the bridge may record the write data internally if it has room and signal completion of the write before the forwarded write has completed.
Or, indeed, before it has begun. The serial interface of PCIe suffers pci to nubus bridge such problems and therefore does not require such complex and expensive designs. PCI-X buses run only as fast as the slowest device, whereas PCIe devices are able to independently negotiate the bus speed.
I'm interested in doing that hack we discussed! You need to be a member in order to leave a comment.

If an address is not claimed by any device, the pci to nubus bridge initiator's address phase will time out causing the initiator to abort the operation. PCI devices therefore generally attempt to avoid using the all-ones value in important status registers, so that such an error can be easily detected by software. There are 16 possible 4-bit command codes, and 12 of them are assigned.
With the exception pci to nubus bridge the unique dual address cycle, the least significant bit of the command code indicates whether the following data phases are a read data sent from target to initiator or a write data sent from an initiator to target. PCI targets must examine the command code as well as the address and not respond to address phases which specify an unsupported command code. The commands that refer to cache lines depend on the PCI configuration space cache line size register being set up properly; they may not be used until that has been done. Soon after promulgation of the PCI specification, it was discovered that lengthy transactions by some devices, due to slow acknowledgments, long data bursts, or some combination, could cause buffer underrun or overrun in other devices.
Recommendations on the timing of individual pci to nubus bridge in Revision 2.
Additionally, as of revision 2. If the timer has expired and the arbiter has removed GNTthen the initiator must terminate the transaction at the next legal opportunity. This is usually the next data phase, but Memory Write and Invalidate transactions pci to nubus bridge continue to the end of the cache line. Devices unable to meet those timing restrictions must use a combination of posted writes for memory writes and delayed transactions for other writes and all reads. In a delayed transaction, the target records the transaction including the write data internally and aborts asserts STOP rather than TRDY the first data phase. Even many video game consoles, such as the Sega Genesisincluded expansion buses; at least in the case of the Genesis, the expansion bus was proprietary, and in fact the cartridge slots of many cartridge based consoles not including the Atari would qualify as expansion buses, as they exposed both read and write capabilities of the system's internal bus."Found new pci to nubus bridge - PCI to NUBUS bridge", and it wants driver software for it.
