Načeloma ne.
Poznalo se bo pri I/O zadevah.
Recimo SSD bo izgubil določeno vsoto read/write.
P.S.
Kakor koli gledamo.
Intela je najbolje prizadel Meltdown, ki pri AMD in ARM ni na vidiku oz. ni dokazan.
Poznalo se bo pri I/O zadevah.
Recimo SSD bo izgubil določeno vsoto read/write.
P.S.
The security flaws that have become the talk of the week date back to over two decades. Two critical vulnerabilities known as "Meltdown" (specific to Intel and admittedly more severe) and "Spectre," affect "almost every system" and can enable attackers to steal sensitive data. While AMD had claimed its chips weren't affected, the company has now clarified that "the threat and the response to the three variants differ by microprocessor company, and AMD is not susceptible to all three variants." The chipmaker also suggests that there is "near zero risk to AMD processors at this time." From Google's security report, it appears that AMD and ARM are also in the affected list, but not as severely hit as Intel.

nov procesor oz 370€ back. To ni nerealna kazen, ce so tolko od mene pri nakupu zahtevali.
Saj ti bug ni iz procesorja naredil obtežilnik za papir.
Saj boste mogoče dobili 5 % popusta pri naslednjem nakupu.
Bomo videli kakšna pohabitev bo dejansko. Če smo uporabniki plačali top $ za njihov produkt, naj bo tako tudi odmerjena 'odškodnina'.
Mimogrede, kaj pa vsi workstationi z xeoni? Jaz sem kar nekaj mašin sestavil s svinjsko dragimi xeoni, ravno zaradi računske moči. Tole vse skupaj je precej neprecendenčno v it consumer relaciji.

Well, ce lahko Spectre flaw popravijo samo z novo generacijo procesorjev, smo pretty much fucked. Za tole bomo rabli vsaj 10 let ce ne vec in do takrat bodo pridobili vse skrivne podatke, ki jih bodo kadarkoli rabili.

Poznale se bojo reci ki delajo syscalle, na desktopu se to dogaja precej redko. Na serverjih, kjer imas razne baze in podobne i/o heavy zadeve, se to dogaja konstantno in znajo bit reci bolj zajebane.

Poznalo se bo tudi pri vsaki prekinitvi (interruptu), katere servisiranje se bo začelo na jedru, ki ni v ring0. Več prekinitev, večja upočasnitev in to je nekaj, kar zadeva tudi namizne sisteme. Še posebej takšne, ki imajo kakšen craptastičen gonilnik za NIC ali pa se je lastnik odločil izključiti "interrupt moderation", da bo imel nižje latence, ker je 1337 gamer.

Pentium FDIV bug @ Wikipedia
Pri tej zgodbi je IBM spinal bulšit, na koncu pa se od njegovega FUD-a ni uresničilo prav nič. Ne pozabi, da so to bili časi, ko je IBM še imel svojo kožo v panogi izdelave x86 procesorjev.

Hahaha, nicesar ne bos dobil.
WHAT THIS LIMITED WARRANTY DOES NOT COVER:
- design defects or errors in the Product (errata)
- damage to the product or errrors or malfunctions in the Product due to . . . malicious code
Verjetno res nič. Ampak po drugi strani je to zgolj in samo neko blebetanje proizvajalca/dobavitelja in menda je v Sloveniji in tudi marsikje drugje zakon nad tovrstnimi blebetanji. V EU ti pravice do uveljavljanja stvarne napake ni možno odvzeti in tudi sam se ji ne moreš odreči: https://europa.eu/youreurope/citizens/c...
Znotraj EU je zato edino vprašanje, če to šteje pod stvarne napake ali ne. Ne pa pobožne želje, ki jih je Intel uspel načečkati na list papirja. Če je od nakupa minilo manj od 6 mesecev bo v bistvu prodajalec (in preko njega Intel) tisti, ki bo moral dokazovati, da očitan defekt ni defekt in ne vpliva na delovanje sistema, pa čeprav bo sočasno objavljal podatke o defektu, ostali pa bodo sočasno poročali o izgui performans in varnostnih tveganjih.

At least for now it's looking like the performance impact of having KPTI support is more noticeable for more virtual machines than with bare metal desktop class hardware, but we'll see what further optimizations come to this code ahead of the Linux 4.16 cycle and what other insight security researchers and developers may be able to shed on this situation in the days ahead.
With these VM results so far it's still a far cry from the "30%" performance hit that's been hyped up by some of the Windows publications, etc. It's still highly dependent upon the particular workload and system how much performance may be potentially lost when enabling page table isolation within the kernel.
Still exploring this vulnerability now known as Meltdown+Spectre and carrying out additional KPTI Linux patches this week, such as testing with Xen, my other available Xeon servers, and also more enthusiast-oriented tests still coming, so stay tuned for any other discoveries and interesting performance tests.

- Pred izdajo CoffeLake so v Intelu vedeli za bug.
V USA bodo padale tožbe (sem skoraj prepričan)
