 Posted: Mon Dec 05, 2022 9:19 pm Post subject: PATA laptop: Is bios SATA to PATA layer any good? |
 |
|
I started kernel with the .config from livegui.
Currently slimming it down to the only necessary.
IIUC, HD kernel stack goes through a bios SATA layer for PATA hw.
Isn't it superfluous to keep it that way?
Should a straight PATA stack kernel be as fast, or somehow even faster? Hence with cancellation of the BIOS feature.
Advices would be welcome in this respect.
Thks 4 ur attention, interest & support.

CaptainBlood,
The BIOS will need its HDD driver. It has to load the the boot loader.
The kernel will use libata for both SATA and PATA devices.
If the BIOS has a PATA or legacy mode, turn it off. That was only ever intended to be used once by Win XP users to load the real driver for the SATA.
The legacy mode usually has essential bits missing, like DMA, so its very slow.
Keep in mind, it was intended to be a use once only feature, so it didn't need a lot of effort spent on it.

BIOS out of reatch,
IIRC SATA layer is to be activated.
The conclusion remains the same, must be kept.
You saved my day from time costly useless testing. 
IIUC kernel PATA layer has to kept too, or is it?

CaptainBlood,
The kernel PATA layer is depreciated. Its full of bitrot and not supported by udev. That's the code that used to give you /dev/hda and friends.
There are new drivers, well kernel 2.6.26 or there about, for PATA chip sets under libata.
PATA devices will get SCSI names using those drivers.

If you mean "ATA SFF support", then ... NO usually you dont need it if not having old PATA devices. I have a native SATA SSD and need only (of course I have also all needed SCSI options):
| Code: | Device Drivers --->
[*] Serial ATA and Parallel ATA drivers (libata) --->
[*] AHCI SATA support
[ ] ATA SFF support (for legacy IDE and PATA) |

Contrary to newer system here, modules explicit loading declarations seems requested here.
Although system boots fine, some drivers are reported missing above.
Are they any benefit for efficiency here?

It looks like this machine has an old PATA CD-ROM. For this you will need:
| Code: | [*] ATA SFF support (for legacy IDE and PATA)
[*] ATA BMDMA support
[*] Intel ESB, ICH, PIIX3, PIIX4 PATA/SATA support |

Until now I tried to keep everything that sounded relevant to the MB design.
Likely some cruft remains here.
Hard to tell which.

I think all which you have enabled as module: SATA_AHCI_PLATFORM, PATA_OLDPIIX, PATA_SCH, PATA_MPIIX, PATA_ACPI, ATA_GENERIC
If you use your CD-ROM and after that you dont find any of them in "lsmod" you can safely remove them.
P.S.: All other settings is good. |

I'll try that, seems reasonable enough 
The hardest part is now to get a CD/DVD media
