| davidc__ | Has anyone looked at producing "fixed" CSR layouts? (Or adding a feature where you can pin certain CSR addresses?) | 01:15 |
|---|---|---|
| davidc__ | I have an application where it'd be really handy to fix a couple CSR locations (such that they are always at a particular memory address) | 01:16 |

| _florent_ | scanakci: i added the UART_POLLING mode for cases similar to yours: do some first BIOS tests with un-validated interrupts | 10:58 |
| _florent_ | scanakci: you should be able to enable it in your design by doing self.add_constant("UART_POLLING", None) | 10:59 |
| _florent_ | scanakci: i could look if that's not working/compiling | 10:59 |
| _florent_ | davidc__: yes i make heavy use of fixed CSR layout on systems that are deployed and where we want some peripherals to always be at the same location (for example FLASH module if a PCIe board to be sure we can update with any version of the software) | 11:01 |
| _florent_ | davidc__: you just need to do something like this: https://hastebin.com/nuwojaciqe.rb | 11:05 |
| _florent_ | davidc__: you can mix fixed and dynamic CSR, it's just that the fixed one are reserved first then the dynamic one use the empty locations | 11:06 |

| davidc__ | _florent_: yeah - I do that, but that presumes the peripheral itself stays consistent internally? | 16:39 |
| davidc__ | (I'm not 100% clear on the rules for how CSRs get ordered in a peripheral; so I'm gonna dig into that today) | 16:42 |

| scanakci | _florent_: thank you. I tried it for Rocket and looks like it works. | 17:30 |

| davidc__ | _florent_: hey, any reason that CommUDP uses a separate 'rx_socket' that binds to a specific port? (rather than looking for responses on the socket it uses for tx?) | 21:00 |
