Well, some clever people at [the biggest user-tracking company in existence, which introduced many of them] thought the same and decided to tackle this [by introducing new protocol-level server-side parameters that only a tiny fraction of companies is going to care about, never mind implement]."

@thomasfuchs@hachyderm.ioFun fact, your computer doesn't have USB ports (USB is a protocol, not a connector).
Funner fact, even if your computer has USB-C receptacles it might not be using any type of USB as protocol for a specific connection.
Funnest fact, there's at least a dozen different types of cables that use USB-C plugs with various capabilities, sometimes mutually incompatible and often silently falling back to slower protocols.

Funny how no one ever talks about driver reaction time as a real weakness in this protocol. And that's assuming the driver is actually paying attention while not doing any of the driving, a questionable assumption at best.

@fluchtkapsel@nerdculture.deSome fun with interfaces and protocols: I have a ThinkCentre m910q which has a single NVMe M.2 interface. I want to connect a PCIe M.2 device. I know that SATA M.2 only supports the SATA protocol. Will a PCIe device work on an NVMe M.2 interface? Or is the answer to that question "it depends"?
Bonus question: I have an OCuLink M.2 adapter with NVMe interface. I want to connect an OCuLink to NVMe adapter at the other end of the OCuLink cable. So far I wouldn't expect any …
@cdarwin@c.imThe leading vaccine regulator at the Food and Drug Administration (FDA) has announced a far stricter course for federal vaccine approvals,
following claims from his team that Covid vaccines were linked to the deaths of at least 10 children.
Experts suggest the announcement will make the vaccine approval process significantly more difficult.
Dr Vinay Prasad, whose vaccine policy direction has been supported by the US health secretary, Robert F Kennedy Jr, told FDA staff that…

@azonenberg@ioc.exchangeLast evening of Christmas vacation before getting back to work for the new year.
Aiming to make it a good one. Working on GPU acceleration of the TIE filter and maybe the histogram block so I can do jitter analysis faster.
The peak at T=0 in the jitter histogram is related to use of the GPU CDR block and doesn't show up in the CPU implementation. It's likely caused by transients of some sort at thread block boundaries and I need to spend more time chasing it, I wouldn'…

@mgorny@social.treehouse.systems#Gentoo #jobserver revealed another problem with steve in particular, and (I believe) the jobserver protocol in general: blocking clients are prioritized over polling clients.
The problem is simple: when handling blocking reads, steve can issue a job token immediately. When handling a poll, it merely indicates that a token is available, and the client must issue another read request to get it. So if tokens are scarce and there are both blocking and polling clients running, the former are likely to be taking all the incoming tokens.
My idea of working around this is to implement temporary reservations. If a client polls for a token, we reserve one for it. The reserved token can afterwards be only read by the same client. This way, both blocking and polling clients get a token — the former get it immediately, the latter get it reserved for them. And if there are no tokens available, both get into a single FIFO queue, for a poor man's round-robin (steve also throttles all reads to one token at a time).
However, polls technically don't guarantee that the client will eventually read the token, so we need to handle reservation expirations as well.

@azonenberg@ioc.exchangePCIe update: I'm now able to parse incoming InitFC1-* DLLPs and store away the credit counts in a register (which I don't actually use for anything yet), and emit a singular InitFC1-P DLLP of my own
Next step will be writing the rest of the setup logic so I can actually fully bring up VC0, then start sending UpdateFC idle DLLPs at regular intervals to keep the link alive when I'm not sending traffic.

@azonenberg@ioc.exchangeFinally had time to sit down and do a GPU version of the constellation diagram filter.
I'm now running this filter graph (4 channels -> 2 differential legs, S-parameter de-embed of dual directional coupler, 3 dB FIR equalizer, 4x sin(x)/x upsample, PAM-3 edge detection, CDR PLL, PAM-3 eye pattern, demux to 2D-PAM3 channels, 2D-PAM3 constellation, 100baseT1 single pair ethernet protocol decode) at about 6.3 WFM/s on 4 channels * 20M points.
This is 504 Msps or a touch over …
@azonenberg@ioc.exchangeI'm going to have to screen record this, I can't believe I got it working this well.
2x 50M point differential Ethernet waveform into subtract filter, CDR, and eye pattern.
Refreshing at 8.3 Hz. With just a little bit more optimization or faster hardware this will be real time.
Then I can start working on getting protocol decodes to run at full rate too.

@azonenberg@ioc.exchangeTime to start $dayjob work so this is it for today.
But here's 100baseTX decoding, eye pattern, eye measurements, bathtub curve, jitter histogram, and more.
Running in real time on the full 1 GB/s (1 Gsps, 2x 500 Msps differential legs) ADC firehose off a ThunderScope, on a 2080 Ti.
As far as I know this is an industry first.
@azonenberg@ioc.exchangeOK, I think I have a reasonably efficient table driven implementation of the 100baseTX scrambler LFSR, capable of predicting future scrambler states with offsets of up to 2^30-1 in constant time.
I still don't grok the math. I ended up doing this by essentially bruteforcing the algebraic solution, creating a class representing a 11th-order polynomial with boolean coefficients symbolically and evaluating the LFSR in a loop 1, 2, 4, 8, 16, etc. times.
The table generator logic …
@azonenberg@ioc.exchangeYes, this is exactly what it looks like. RJ45 probe fixture -> ThunderScope -> ngscopeclient -> eye measurements and protocol decodes -> Wireshark.
At >80% of real time, and we're closing in on the last few bottlenecks rapidly.
