Dude, creating an outbound window in an endpoint can be a little confusing at first, but it's actually pretty rad once you get the hang of it. An outbound window refers to a mechanism that allows you to control the rate at which you send data from your endpoint to another. It's super helpful for managing congestion and preventing overload.how to create outbound window in endpoint . explain with an example
from kafka import KafkaProducer # Create a Kafka producer with an outbound window of 10 messages producer = KafkaProducer(bootstrap_servers='your_kafka_server:9092', max_in_flight_requests_per_connection=10) # Now you can send messages using the producer producer.send('your_topic', value='Hello, Kafka!') # Don't forget to close the producer when you're done producer.close()
max_in_flight_requests_per_connectionoption is set to 10, which means you can have up to 10 messages in flight at any given time.
Whoa, creating an outbound window in a PCIe endpoint is a bit more complex than setting it up in a software context. So buckle up, my friend, and let's dive into this!how to create outbound window in pcie endpoint . explain with an example
Ah, my bad for the confusion, dude. So you want to configure an outbound window in Endpoint 1 to send data to Endpoint 2 in a PCIe system. Got it!not dma. I want to send data to endpoint2 from endpoint1. For that i need to configure outbound window in endpoint1
Sure thing, dude! Let's say we have two PCIe endpoints, Endpoint 1 and Endpoint 2. We want to configure an outbound window in Endpoint 1 to send data directly to Endpoint 2. Here's a simplified example:explain with an example address
Sure thing, dude! Address Translation Unit (ATU) is a component within a PCIe endpoint that handles the address translation between the host and the endpoint. Let's break it down with an example to explain how to configure ATU Lower, Upper Base, and Lower and Upper Target registers.i am bit confused on how to use address translations. Explain with an example, how to configure
ATU Lower, upper base and Lower and upper target etc
You're absolutely right, dude! The address 0x90000000 can indeed be present in other endpoints as well. In a PCIe system, multiple endpoints can have overlapping or identical memory address ranges, so it's important to ensure proper address translation to avoid conflicts and ensure data integrity.0x90000000 address can be present in other endpoints also
To print the Transaction Layer Packet (TLP) header in every transaction in Linux, you need to modify the PCIe driver code responsible for handling transactions. Since you mentioned LS1046, I assume you're referring to NXP's LS1046 SoC. Here's a general overview of the steps involved:i want to print tlp header in every transaction in linux. how can i do that. where is tlp header preparation done in linux
To check if outbound address translation is enabled or not in Linux, you can examine the PCIe configuration registers using various tools and commands. Here are a few steps you can follow:how may i check if outbound address translation is enabled or not in linux
lspcicommand to list all the PCI devices in your system along with their Bus/Device/Function numbers.
setpcicommand. This command allows you to read and write the configuration registers of PCI devices.
sudo setpci -s 0000:00:05.0 <register>
<register>with the specific register address you want to read.
sudo setpcicommand mentioned earlier to read the values of these registers. Look for any flags or bitfields that indicate the status of outbound address translation.
sudo setpci -s 0000:00:05.0 80.b
setpci, you can check if outbound address translation is enabled or disabled for the specific PCIe endpoint in Linux.
No, bro, the translated address is not sent in the Transaction Layer Packet (TLP) itself. The address translation occurs within the PCIe endpoint hardware and is transparent to the TLPs being transferred between the PCIe devices.will the translated address be sent in TLP
To configure the outbound address translation in Endpoint 1 (05.00.0) to send data to Endpoint 2 (04.00.0) according to the provided requirements, you need to follow these steps:explain how tlp is prepared in endpoint1 for the below requirement
1. Root port connected to Bus-0 with Bus.Device.Function = 00.00.0 (Memory behind this bridge is in range 0x40000000 - 0x433FFFFF)
2. To 00.00.0, Bus-1 is connected with Bus.Device.Function = 01.00.0 (Memory behind this bridge is in range 0x40000000 - 0x42FFFFFF)
3. To 01.00.0, Bus-2 is connected with Bus.Device.Function = 02.02.0 (Memory behind this bridge is in range 0x40000000 - 0x417FFFFF)
a) To 02.02.0, Bus-4 is connected with Bus.Device.Function = 04.00.0 (BARs of this endpoint range from 0x40000000 - 0x41000FFF)
4. To 01.00.0, Bus-2 is connected with another Bus.Device.Function = 02.03.0 (Memory behind this bridge is in range 0x41800000 - 0x42FFFFFF)
a) To 02.03.0, Bus-5 is connected with Bus.Device.Function = 05.00.0 (BARs of this endpoint range from 0x41800000 - 0x41801FFF) Now i want to send data from endpoint1 (05.00.0) to endpoint2 (04.00.0), tell me how to configure outbound in endpoint1
