Last night, I received a task to investigate a massive #performance regression in certain parts of the game.
So today I began investigating and ran the latest build on my 4 testing machines. And indeed, the machines that had an #Intel#GPU only achieved ~10% of the FPS they usually had. "Oh no!" I thought, and spent all day profiling and disabling various engine features, but no matter what I did, the performance didn't improve much.
And then I found it. Those Intel machines still had #Mesa DLLs in their build directories from the last time I was investigating a graphics driver issue. Which means they have been using a #software implementation of #OpenGL all this time! :drgn_stare:
I removed the DLLs and the performance returned to normal.
And now I'm back to square one, unable to reproduce the performance issue. :drgn_weary_sob:
A recently discovered vulnerability that affects lots of Intel CPUs could steal your data, but there's a fix. The downside? It'll cost you performance.
"Recently, however, several major corporations, including AT&T, Comcast, Intel, and Mastercard, have resumed donations to Jordan [after ceasing donations following the Jan. 6 insurrection attempt]. …
Popular Information asked these four companies what Jordan has done since January 6 to alleviate concerns about donating to his campaign. None of the companies responded."
In this one, we have the Cyber Resiliency Act, a new EU set of regulations that might seriously harm Open Source software, we have repairable laptops from #Framework and (in the future) from #Lenovo, and we have some big performance improvements for #Intel GPUs on Linux:
Newly declassified US #intel claims Russia is laundering propaganda through Westerners
Alert: Former moscow bathroom robber Vlad Putin and his murderous FSB (KGB) use relationships with traitorous republicans to spread Russian propaganda and disinformation.
Vlad putin doesn't need to bomb the USA, he just buys republicans to destroy America.
Russian intelligence is operating a systematic program to launder pro-Kremlin propaganda through private relationships between Russian operatives and US and western targets, according to newly declassified US intelligence.
US #intelligence agencies believe that the Russian Federal Security Service (FSB) is attempting to influence public policy and public opinion in the West by directing Russian civilians to build relationships with influential US and Western individuals and then disseminate narratives that support Kremlin objectives, obscuring the FSB’s role through Putin shills, hello republicans.
The United States has landed another blow to China’s technological advancement, by revoking licenses that allowed Intel and Qualcomm to buy and sell chips to Huawei Technologies, reports @engadget.
Huawei was hit hard when it was placed on U.S. trade restrictions lists in 2019, but a recent comeback — including the launch of an AI-enabled laptop powered by an Intel chip — appears to have renewed the government’s national security worries.

On this month in 1970, Intel released the first commercially available DRAM chip, the Intel 1103. The technology replaced Magnetic-Core Memory, which was the main form of RAM since the second half of the 1950s. Nowadays, DDR5 is still DRAM memory! #RetroComputing#Intel
#Intel ripping into #AMD for confusing and misleading product names and numbering schemes is rich, seeing as their "latest tech" 14th gen is such a minuscule refresh of their previous 13th gen, that you have to look for improvements with a microscope to find any 😂️
Bit-Rauschen: Intel bestellt Chips bei TSMC für 14 Milliarden US-Dollar
Intel baut neue Chip-Fabs, kauft aber groß in Taiwan zu. ARM grämt sich über zu geringe Lizenzgebühren und in Frankreich befürchtet man den Atos-Ausverkauf.
Reptar: Sicherheitslücke in Intel-CPUs bedroht Cloud-Server
Angreifer, die eine virtuelle Maschine auf einem Host mit Intel-CPU kontrollieren, können diesen unter Umständen zum Stillstand bringen. Intel flickt die Lücke.
It looks like Intel shuffled registers around again somewhere between skylake (2016) and tigerlake (2020), and the haiku drivers only works by pure luck (reading and writing nonexisting registers, and relying on the bios to setup most things, I guess). So that's yet another thing to fix on the todo list...
I am narrowing down the address range where there's a register that crashes the system by just reading it. I got it down to 32KiB today, I'll continue tomorrow.
If you have an idea which register in intel graphics (gen 11) in the range 60000-64000 may cause that, I appreciate your help!
But I think all other people who might know about this all work at Intel?

Sometimes I lay awake at night and think about where we would stand as a society today if the Transmeta #Crusoe wouldn't have failed due to too low supply for the sudden rise in demand.
Would intel CPUs be designed the way they are now? Or would intel have found a different way of saving energy? Maybe a #Pentium 4 would have been a really good, innovative design in that world.
Would we have another big player in the desktop and laptop #CPU market with Transmeta? Would #AMD have bought them by now?
Would Apple have considered switching to #Transmeta CPUs if there would have been several improved successors over the years?
Why is it that people seem to only think about worrying and anxiety-inducing topics when they can't fall asleep?
Would #intel have extinguished the new competitor anyway by incorporating the Crusoe's concepts, e.g. into their Pentium M line.
How would the x86-64 architecture differ from what it is?
Would Linus Torvalds have had the same amount of time available for work on Linux? Would he have delegated decisions more or earlier and if so, which decisions in the kernel development would have been made differently?
The Golden era of Mini PCs - more powerful and often less $ than a #RaspberryPi - because we are in the tail end of #Intel's monolithic die. Notice #AMD has no super value proposition low end chips to go into a ~$150ish mini! Why? Chiplets and fabrics. Intel missed this boat and when an i9 doesn't come out of the oven right they fuse off features and it becomes an i7, i5, i3, all the way down to the kind of amazing value n100 which you find in $120 PCs. Intel is onto chiplets now, era to end!
