Druhy "disk" do Eee PC 701 - problem s DMA
Napsal: 07 srp 2016, 23:01

Uvod:
Asus Eee PC 701 je prvy netbook na svete. Nema HDD, ale na doske je integrovane 4GB "SSD" - radic SM223 a 4ks flash, zapojene ako CF karta v IDE mode.
Na rozsirenie je pod spodnym krytom vedla RAM konektor FLASH_CON. Je to fyzicky mini PCI-e konektor, ale inak zapojeny - su tam vyvedene IDE signaly - vid priloha (zo schemy Eee PC 900, ale malo by to sediet).
Rozsirenie:
V mojom kuse nebol konektor osadeny, tak som ho tam pridal (zobral som z nejakeho vraku). Zohnal som si vhodny "SSD" - je to z ineho Eee PC, tiez 4 GB, radic je PHISON PS3006-L.
Oba "SSD" vidiet - povodny je MASTER, druhy je SLAVE. Problem je, ze ked je vlozeny druhy (SLAVE), prestane fungovat DMA na prvom (MASTER) - kernel hlasi "lost interrupt" a postupne znizuje rychlost z UDMA66. Ked konecne vypne DMA (dostane sa na PIO4), tak sa to rozbehne. Zaujimave je, ze DMA na druhom (SLAVE) disku vtedy funguje!
Skusil som prelepit paskou piny DREQ a DACK - vtedy prestalo fungovat DMA aj a druhom disku, ale problem s MASTERom zostal bez zmeny. Ked som prelepil IRQ, tak sa mi nepodarilo nabootovat - kernel sa donekonecna pokusal citat zo SLAVE disku, ale vyzeralo to tak, ze s MASTERom nebol problem.
Co s tym moze byt? Ze by ten SLAVE disk "zozral" IRQ pulz od MASTERa?

Nejspíš se ty disky na sběrnici nedomluvily, když ten druhý zavinil propustnost toho prvního.
Kdysi někdo chtěl do Eee přidat disk přes redukci IDE->CF, tak jsem si vzpomněl (sešlo z toho).
Tady má udělaný přepínač pro CSEL vnitřního nebo přidaného disku. Taky tam je
odkaz, kde právě řeší zvýšení propustnosti propojováním pinů (nezkoumal jsem jakých, nebo jestli to přizemňuje).
Jinde tam doporučuje i BIOS 1302.

CSEL interneho disku som nasiel podla datasheetu SM223, ten pin je pripojeny na zem, takze natvrdo MASTER. Menit to nechcem. CSEL druheho disku je nezapojeny - je tam miesto pre odpor na zem alebo na VCC - ale PS3006 ma interny pull-up, takze ho netreba.
Ak som to z prekladaca dobre pochopil, tak Rusi tam riesia detekciu 80-ziloveho kabla. S tym nemam problem, Linux ma tento model vo whiteliste, takze UDMA/66 funguje. Ale ked pridam ten druhy disk, tak UDMA funguje len na nom.
Nove zistenie - ak druhy disk zakazem v Linuxe (libata.force=2.1:disabled), tak UDMA interneho disku funguje!
Takto to nefunguje:

sice trochu OT ale mal som eee901 s 4 GB (zmienovany Phison) a 8 GB a po vymene toho 8GB za 32 som chcel ze ten 4GB dam prec a kupodivu bez neho to zas nevidelo ani ten 32GB... takze tam musel zostat a dal som na neho image cisteho systemu ...

Keby si dal ten 32 GB dovnutra namiesto toho interneho, tak by to podla mna fungovalo. Ten slot bude nastaveny ako MASTER (CSEL uzemneny), druhy je SLAVE. A SLAVE disk nemoze bez MASTERa fungovat.

Jen ze zvědavosti, co když vypneš jen DMA na tom přidaném disku?

To som skusal - ziadna zmena na MASTERi, tzn. nefunguje potom DMA nikde.

Skusil som prehodit "disky", tzn. na internom som odstranil z CSEL na zem a na pridavnom som tento signal uzemnil. Ziadna zmena - DMA na internom "disku" nefunguje, na pridavnom ano...

Jaký je u něj rozdíl v rychlosti s/bez DMA? Nestačilo by mít ten přidaný na systém a interní třeba na /home?

IDE bez DMA je nepouzitelne kvoli vysokej zatazi CPU. Asi budem musiet zohnat nejake ine SSD. Alebo mSATA - na tom konektore su vyvedene aj SATA signaly (na standardnych poziciach). Akurat v BIOSe podporu SATA nevidim, ale to by vadit nemalo.
