Open-source scsi device

[Rochabian]

Hum... 46.0 works on 3.1 but freeze on 3.9 with CF or SD. I don't understand

Perhaps a timing issue but hard to know.

Your version allow FMV access with HDD with minor freeze (appears sometimes)
With SD or CF, freeze when workbench appears .

What has the FMV module to do with scsi.device ?
Could it be a memory timing problem because FMV share memory address if i remenber well that's why only 4Mo are allowed on SX-1 with FMV

The OS3.9 BB2 scsi.device fix 8Mo memory problem on SX-1 but freeze when acces to FMV

Do you know what changed between the 43.45B and 46 that could do freeze and interfer with the use of FMV ?

I dont know what was changed except some fixes and extension. I mostly optimised only this version for speed and size (this is not finished).
For OS 3.9 You can start without startup-sequence.
later enter
c:type s:startup-sequence

and enter every line from startup-sequence, one by one.
You will be know where is problem. Maybe commodities, WBStartup or something similar.

I remember one fix for this version, no Max Transfer problem.
But I never tested this because i dont have access to HD where this problem occured.
Then You can change MaxTransfer value to every value and check if minor freeze occured.
Also for HD You can use V46.1, is perhaps the fastest, and no minor freeze can occured, i think.

I just tested v46.0 and v46.1 on my A1200 + Blizzard 1230 IV + 60 ns RAM + CF on IDE port. v46.0 turned out to be the fastest (also with respect to v43.x):

SysInfo results (b/s):
* v46.0 / without IDEFix: 1941807
* v46.0 / with IDEFix: 2032124
* v46.1 / without IDEFix: 1927829
* v46.1 / with IDEFix: 2026886

Great job, thank you!

From my memory my, main betaster made also other tests. He copied 600 MB (I dont remember if it was CD ISO or files from ISO), and if I remember right difference was very visible in copying speed.

In that case the filesystem(s) involved also played a role.
I just tried to copy a 14814708 bytes file from CF to RAM, and both with v46.0 and v46.1 it took about 11 seconds.
By the way, the FS is PFS3AIO; the OS (I forgot to mention it in my previous post) is 3.9.

Also, I made a few tests with SCSIBench using 16 and 64 kB transfer blocks: again v46.0 performed a bit better (about 10 kb/s more).

Ok, seems to be dependent to something else. Here is info from my betatester:

Is the scsi.device 46.0 LBA 48bit compatible, for use with drive >128Gb ?

I use a 256GB SD Card

I can see partitions below 128 Gb but those which are above are marked Uninitialized, altough they are filled with full of stuff

Does someone has tested with disks >128GO ?

In theory scsi.device v46.0+ can handle 2TB disks, but you must have file system which can handle this. It was never tested.

Ok i've used SFS 1.279 that handle max partition size of 128Go ( SFS\00 )
I have partitions of max 50Go, the first one is under 2Go
I access at all partitions in WinuAE when i mount my SD card with uaehf.device
I will test with other file system

[Rochabian]

Don, your scsi.device handle 1TB drive nicely ;-)
I've used a 1TB SATA drive with a SATA to IDE converter and, yes LBA48 is working great ! I've created partitions beyond 128GB and read from them successfully.
On my last post, i was using a SD to IDE adapter but those doesn't seems to like LBA48
I've been able to use a SD Card of 128GB with SD to IDE, it's the maximum capacity usable with this adapter.

1TB in my SX-1 to store videos is really cool!

Thanks again for the 46.0 version, it's really a must have !

Ok. Thanks for tests.

Topic name mentions "open source" but this is not cleanly written from scratch or under an Open Source license, but rather, using old proprietary AmigaOS code as a base?

If so, perhaps "open source" should be removed from the thread name.
