heyyyyyy.

@implr @whitequark @azonenberg Maybe not for much longer, given the way storage prices are going... I get the impression that there is a lot of it left over from back when Intel were pushing it for the desktop market.

[zwol@masto.hackers.town]

@whitequark @azonenberg ... you can still buy optane ??!?

[whitequark@social.treehouse.systems]

@niconiconi beautiful

[jameswidman@mastodon.social]

@whitequark i like the fact that when i google that, the search results contain a bunch of references, some manual entries, but apparently no explanations anywhere.

oxide was right to remove the bios root and branch

[whitequark@social.treehouse.systems]

i found an explanation (or what passes for an explanation) for the PCIe Stop & Scream option

what the fuck does this mean? ask someone smarter than I am

[whitequark@social.treehouse.systems]

please also enjoy this beautiful enumeration

• Smart Auto
• Auto
• Enabled
• Disabled
• Manual

i don't know where to begin. would "Enabled" or "Disabled" not imply "Manual"? what the fuck is the difference between "Auto" and "Smart Auto"??

[dysfun@social.treehouse.systems]

@whitequark fuck yeah american megatrends

[whitequark@social.treehouse.systems]

why do they call it PCIe Stop & Scream when you enabled DS packet on DMI in with the EP bit set of out in their UT bit set

[jn@boopsnoot.de]

@whitequark i was going to ask "how" regarding the splitting, but the AliExpress search results for "pcie riser x4x4x4x4" speak for themselves

[whitequark@social.treehouse.systems]

@jn hell yeah baybee

[kc@mastodon.dragoncave.dev]

@whitequark this motherboard is a piece of modern art

[xyhhx@social.treehouse.systems]

@whitequark w-what

[xyhhx@social.treehouse.systems]

@whitequark dumb auto, obviously

[xyhhx@social.treehouse.systems]

@whitequark (i have no idea)

[hennichodernich@radiosocial.de]

@whitequark Isn't that this song by OneRepublic?

[whyrlpool@slime.global]

@artemist @whitequark need to try this along with gps disciplining the CPU clock like i did on a pi

[whitequark@social.treehouse.systems]

@xyhhx context https://social.treehouse.systems/@whitequark/116143444311471353

[xyhhx@social.treehouse.systems]

@whitequark yeah i found this after and tbh it doesn't clear much up lol

[ingalovinde@embracing.space]

@niconiconi @whitequark but that's Broadwell, just one generation before Skylake, surely its IPC is not _that_ low?
And the one they're giving out isn't even low-end, but 10-core.

[jripley@mastodon.social]

@whitequark The explanation in a random Intel chipset doc I found isn't that much better:

https://www.intel.com/content/dam/doc/datasheet/x58-express-chipset-datasheet.pdf
--
PCIe/DMI “Stop and Scream”
...per PCIe port
...disallow sending of poisoned data onto PCIe and instead convert disable the PCIe port that was the target of poisoned data
...there have been PCIe/DMI devices that have ignored the poison bit, and committed the data which can corrupt the I/O device
--

So, disable PCIe port on error, instead of tagging data as poisoned. Nice name.
