Topology: VL822 hub + 4x ASM235CM (?) USB Gen2 - SATA bridges.
Tested with 4x WDC WD80EAZZ-00BKLB0 on an AMD X399 chipset.
~200MB/s from a single drive (this is about what the drive can do).
On a Gen1 port, I get ~400MB/s across all 4 drives. On a Gen2 port, ~800MB/s, give or take.
Power buttons power cycle the individual ASMedia controllers.

| brcmfmac: chip: Only disable D11 cores; handle an arbitrary number | |
| At least on BCM4387, the D11 cores are held in reset on cold startup and | |
| firmware expects to release reset itself. Just assert reset here and let | |
| firmware deassert it. Premature deassertion causes weird | |
| nondeterministic AXI errors on firmware startup. |

| * m1cat: a proof of concept for the M1RACLES vulnerability in the Apple M1. | |
| * | |
| * This program implements a covert channel that can be used to transmit data | |
| * between two processes when run on the Apple Silicon "M1" CPUs. | |
| * | |
| * The channel is slightly lossy due to (presumably) the scheduler sometimes | |
| * scheduling us on the wrong CPU cluster, so this PoC sends every byte twice | |
| * together with some metadata/framing bits, which is usually good enough. | |
| * A better approach would be to use proper FEC or something like that. |
