This is using Thunderbolt networking as transport, which incurs a bit of overhead. But starting with the upcoming Linux v7.2, there's a new feature called USB4STREAM to use raw Thunderbolt packets as transport with minimum overhead

Fun fact (or not so fun if you're a subscriber): Somebody is spamming kernel mailing lists under the name Marian Corcodel with a 26 MByte message multiple times per day containing a collection of nonsensical patches. Looks AI-generated

As Eric has correctly stated above, we believe iwd (Intel Wireless Daemon), or rather the ell library it relies on (Embedded Linux Library) is the only relatively widespread user space application relying on it.

If you need a lot of RAM, usually you need to buy servers with multiple CPUs to which you can attach the memory. Because the amount of DRAM you can attach to one CPU is limited. If you don't have the need for all the extra CPUs, just

The original Raspberry Pi SoC (BCM2835) is ARMv6 with VFP2 Hard Float support. Debian's "arm" architecture is ARMv7 with VFP3. It doesn't support BCM2835. Debian's "armel" architecture is ARMv4. It doesn&#

Thunderbolt devices appear in the OS as a PCIe switch, so you need two additional bus numbers (one for the Switch Upstream Port and one for the Switch Downstream Port). If the device is hotplugged to a port which has run out of bus numbers,
