Americký výrobce čipů Nvidia se stal první firmou na světě, jejíž tržní hodnota dosáhla pěti bilionů USD (104,5 bilionu Kč). Nvidia stojí v čele světového trhu s čipy pro umělou inteligenci (AI) a výrazně těží z prudkého růstu zájmu o tuto technologii. Nvidia již byla první firmou, která překonala hranici čtyř bilionů USD, a to letos v červenci.
Po Canonicalu a SUSE oznámil také Red Hat, že bude podporovat a distribuovat toolkit NVIDIA CUDA (Wikipedie).

České základní a střední školy čelí alarmujícímu stavu kybernetické bezpečnosti. Až 89 % identifikovaných zranitelností v IT infrastruktuře vzdělávacích institucí dosahuje kritické úrovně, což znamená, že útočníci mohou vzdáleně převzít kontrolu nad klíčovými systémy. Školy navíc často provozují zastaralé technologie, i roky nechávají zařízení bez potřebných aktualizací softwaru a používají k nim pouze výchozí, všeobecně známá

Dobrý den. Mám Ubuntu 16.04 64bit. Koupil jsem si tento převodník z HDMI do USB. Můj notebook má jen USB 2.0. Po připojení funguje:

lspci -vvnnTaktéž by se hodil výpis připojeného HDMI přes USB 2.0 a přes ExpressCard adaptér, možná s nějakým USB zařízením v tom adaptéru:
lsusb -vvPřevodník teda na normálním USB 2.0 funguje? Jaké rozlišení jsi zkoušel (z těch co na USB 2.0 fungují)? Myš není moc dobrý nápad. Jedna USB myš co tady mám jede jen na low speed usb 1.0, což je úplně někde jinde. Ideální by bylo jiné usb 3.0 zařízení nebo aspoň usb 2.0 (třeba flashka, čtečka, webkamera!). Připojuješ převodník se zapojeným HDMI nebo naprázdno? Vyzkoušel jsi obě varianty? Jaký kabel používáš na připojení toho HDMI do počítače. USB 3.0 vyžaduje speciální kabel, ten konektor je s USB 2.0 zpětně kompatibilní, ale pro 3.0 mód má navíc další dráty v sobě. Je v pořádku kabel? Není moc dlouhý? Mám pár USB 2.0 zařízení, co na moc dlouhým USB kabelu odmítaj fungovat. To se obvykle projevuje náhodnými "can't read configurations, error" a nebo timeouty. Pokud jsi nejsi jistý zda to je fakt USB 3.0 kabel, tak udělej foto vnitřku konektoru (měly by tam být staré piny + nových 5). BTW Na tom fotu toho HDMI: nezdá se vám že je v tý krabičce USB host konektor? Neměl by tam být spíš device? Teda ledaže by šlo USB 3.0 zapojovat každej s každým... P.S. Jen tak, kdyby se v tom někdo chtěl hrabat:
[ 1677.160714] usb 4-2: can't read configurations, error -71-71 je EPROTO (chyba protokolu) ... ale nejspíš to je vyústění těch chyb předtím.
Tak, zkusím to vzít popořade.
Používám modrý USB 3.0 kabel, který byl součástí dodávky HDMI převodníku.

Rozlišení videa se mi na USB 2.0 automaticky (v cheesee nebo OBS) nastavi na 1280x720 a funguje plynule. Mohu nastavit až 19020x1200, ale to už se strašně seká.
HDMI převodník není v USB 3.0 funkční ani "naprázdno". Viz. dmesg s chybami v mém prvním příspěvku. Není podle mě tedy podstatné, jaké HDMI zařízení do něj připojím, nicméně zkouším foťák Sony Alpha-5000 a akční kameru EX5000.
Moc děkuji za snahu mi pomoct.

1280x720Je to opravdu 60Hz? Aby se nevynechávaly snímky. Na USB 2.0 máš jak tady někdo podotknul maximálně tak 30MBps (možná víc, pokud je sám na řadiči a je to jen jedním směrem). Pro 1280x720 to odpovídá tak 300 pro FPS*bpp. Což by mohlo být tak 30fps a 12bpp (což je v RGB hnus), nebo nějaký komprimovaný YUV (kterej to je by ukázal ten nahrávací software - ideálně třeba mplayer nebo "v4l2-ctl --all" a právě by to nejspíš šlo vyčíst z toho lsusb -vv). Nicméně vidím jeden problém zde:
03:00.0 USB controller [0c03]: ASMedia Technology Inc. ASM1042 SuperSpeed USB Host Controller [1b21:1042] (prog-if 30 [XHCI]) LnkSta: Speed 2.5GT/s, Width x1, TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-Vypadá to že tvůj čipset (podle jednotlivých "PCI bridge [0604]: Intel Corporation 5 Series/3400 Series Chipset PCI Express Root Port") umí maximálně PCIe 1.1, takže ta ExpressCard PCIe 2.0 karta sice fungovat bude, ale nedosáhne maximální rychlosti USB 3.0. To by teoreticky vadit nemělo při enumeraci USB zařízení, ale zrovna UVC je dost fujtajbl na enumeraci
. Jinak to samozřejmě nebude fungovat pokud budeš chtít přenos plnou rychlostí USB 3.0 (resp cokoliv mezi 250MBps až 500MBps). Stejné rozlišení, co fungovalo po připojení na USB 2.0, by ale mělo fungovat. To můžeš otestovat tím, že připojíš ten HDMI přes obyčejný USB 2.0 kabel do té XHCI karty.
Potvrzení z wikipedie:
On some old (2009–2010) Ibex Peak-based motherboards, the built-in USB 3.0 chipsets are connected by default via a 2.5 GT/s PCI Express lane of the PCH, which back then did not provide full PCI Express 2.0 speed (5 GT/s), so it did not provide enough bandwidth even for a single USB 3.0 port.Ještě jsem v jedné diskuzi našel link_quirk parametr pro xhci_hcd, takže pokud más xhci-hcd jako modul (je zobrazenej jako "xhci_hcd" v lsmod výpisu), tak ho rmmodni a pak ho načti s parametrem:
modprobe xhci-hcd link_quirk=1V případě že je ten modul v kernelu, tak by mělo fungovat přidat do kernel cmdline něco jako:
xhci_hcd.link_quirk=1Ale přesnou syntaxi hádám (+ někde se v kernelu používá podtržítko a na jiném místě pomlčka).

find /sys/module | grep uhci | grep parametersTo by mělo najít soubor "link_quirk", jehož obsah by měl být "1". Pokud bude "0", tak ty kernel parametry xhci driver nedostal. Teď jsem si ale všimnul tohodle:
wSpeedsSupported 0x0008
Device can operate at SuperSpeed (5Gbps)
bFunctionalitySupport 3
Lowest fully-functional device speed is SuperSpeed (5Gbps)
To je dost divný. Podle USB 3 specifikace by to mělo podporovat jen a pouze superspeed zařízení (tedy žádný fullspeed a highspeed). Bylo v XHCI zapojeno něco když jsi pouštěl ten lsusb -vv příkaz?
Koukal jsem se do zdrojáků kernelu a ASMedia má nefunkční bulk stream přenosy. To by ale v případě "webkamery" nemělo vadit, ta používá isochronní. Stejně by se ale hodil ještě jeden výpis pro stav:
Intel and NEC USB 3.0 host controllers are known to work. ASMedia controllers are known to not work.
# find /sys/module | grep uhci | grep parameters /sys/module/uhci_hcd/parameters /sys/module/uhci_hcd/parameters/ignore_oc /sys/module/uhci_hcd/parameters/debugZapojil jsem fkashku do USB3.0 karty a funguje. Do USB2.0 jsem připojil převodník a také funguje.

Tak až to zadám do zavaděče z - nebo _, vždy mám jen tenhle výstup:Kruci já blbec tam nechal uhci (mám akorát USB 1.0 a 2.0), mea culpa má to být:
find /sys/module | grep xhci | grep parametersHmm tak podle toho výpisu mám obavu, že i pokud by byla USB 3.0 enumerace v pořádku, tak to tvé požadavky nesplní. Za předpokladu, že máš opravdu vyvedenou PCIe 1.1 na ExpressCard, tak ta má přenosovku 250MBps a pro rozlišení 1920x1200 je rychlost při 60fps (dwFrameInterval[0] = 166667*100 ns):
dwMaxBitRate 2211840000Což odpovídá 276MBps (ale ještě se posílá nejrůznější komunikace pro USB řadič a audio a protokolové overheady). Takže budou vypadávat některé framy. Samozřejmě to nemění nic na tom, že při 30fps by to mělo fungovat určitě (cca 138MBps, to téměř dá i starý PCI) a to, že by se to mělo tak jako tak nadetekovat.
Zapojil jsem fkashku do USB3.0 karty a funguje.Divný, podle podpory standardu z lsusb by to mělo umět jenom USB 3.0 ale asi maj jen chybu v oznamování toho co podporujou
