yes, currently ( and maybe means forever ) bifurcation not supported on X1000 and X5000.

PA6T-1682M in X1000 has 8x PCIe root inside ( used five in our config), in that case it is fully configurable via firmware - so theoretically bifurcation is possible. Yes, I know the firware rights problem, and also support for Polaris in firmware has bigger sense and priority.
P5020 in X5000 has four PCIe roots ( uses two ), but in this case I am not sure if it is fully configurable via firmware, or there should be some hardware. As you said, It cannot be freely configurable.

All it means - forgot the bifurcation.

I agree there is no real need for more than one NVME. From my side it is only pure interest what is possible. To have one in Amiga is really great thing!
Also, if I succseed to divide x8 slot to two x4, I have usecase for this, but no two NVMEs.
And don't worry about booting, it should be easily workarounded.

So if I found working PCIe switch for this purpose, I will note it here.

@GregorQuote:

My (now only) theoretical opinion:
- most of adapters with two or four M.2 PCie NVMe not works, becouse it needs motherboard with PCIe bifurcation ( splitting ) support.
( X1000 and X5000 theoretically can support this, both CPU has free PCIe roots, but it needs changes in firmware = i.e. no support in real )

- adapters with two M.2 ( one PCIe and one SATA M.2 ) will work, becouse fist M.2 use PCIe directly and second M.2 should be connected to SATA adapter - it sounds crazy, but such adapters are very common

- adapters with packet swith chip ( like Asmedia, ASM28xx ) "can" works. I have one in my shopping list and I will post here experiences.

But:
- switch allways causes latency
- NVME need PCIe x4 for full speed
so it can make sense on X1000 with x8 slot only - I want test to split x8 slot to: x4 graphics card for linux and x4 for NVMe

Anyway, if it will works, I post here also speeds for comparison.

@geennaam

yes, DiskSpeed is test of whole disk subsystem incl disk caches, so maximal results can be bigger than bus throughput.
SCSI speed is test of bus throughput - so it gives much lower results than DiskSpeed

I am using both for benchmarking. For example Pegasos 2 1.33 Ghz + AOS4.1fe + SATA SSD:
DiskSpeed Read average= 128 MB/s, Read max= 205 MB/s .. it is more than PCI and SATA1 limit
SCSISpeed Read average= 41 MB/s, Read max = 74 MB/s

@Lio

you cannot boot, becouse you need to load kernel module.
But a little workaround might help to have all disks, includes System: on NVMe.

I am using on old NG machine this:
- on firmware readable partition ( Pegasos 2 IDE, CF card, FFS ) I have loader amigaboot.of and kernel modules ( /kickstart directory )
- on PCI SATA SSD I have System:, Work:, etc... all other disks

I think it will work the same way on X1000/X5000.
- amigaboot.of and kernel modules on SATA small partition, and rest on NVME...

@joergQuote:

Thanks joerg, it is interesting information. Are there any more detailed info please?

I am interested in this questions:
- is better disable diskcache.library.kmod in all new systems with SATA SSD too? like Sam440, 460, X1000, X5000
- is better disable diskcache.library.kmod in all old systems with PCI-SATA SSD? like Micro, XE, Pegasos 2 - this the same like Sam440 becouse of the same SiI 3x1x controller.
- and what about if I have combination HDD + SSD in X1000 ? Is better to use diskcache?

I am using SFS everywhere.
And sorry, I am not found any documentation regarding this.

@geennaam
I will see. PCIe is directly attached, but generation 1.0.

I have to upgrade a litle my X1000 - gfx card sometimes flashes and need new OS installation, is a little mess there .
Than I will do complex SSD tests, your NVMe + internal SATA2 + PCI SATA1

BTW. your driver cames at the right time - I have full all four SATA slots.
And I am run out of PCIe slots - x8 is now for linux graphics card.

Is possible split PCIe x8 to x4 + x4 without changes in CFE ? CPU has free root hub ( eight total ), but there is no option to do it in CFE.
Maybe will works somethnig like mentioned here. But for x8.

@geennaam

thanks. I will test immediatelly in X1000 ( I know, the speed will be lower, .. )

great!!

That is great news, thanks!
Pls, I cannot find it on os4depot.net, can you share direct link?

@MamePPCA1

thx

@Deniil

It is better to have only one monitor file in Devs:Monitors/, put all other unused to Storage/Monitors

You can name it "Radeon" or "Radeon HD 6570", it doesn't matter.
CMPLENGTH ... should be lenght of name of your monitor, i.e. 6 or 14
BOARDNAME ... should be name
DDCMODE=All ...is best for all modern monitors, card reads possible resolution from monitor.
Alternative is manually write here all resolutions and frequencies - don't do it, only if automatic DDC not works with old monitor.


Answers:
1. - What is a DEVS:Monitors/"monitor" anyway?
In real monitor file is not config file for monitor, but for graphics card.
You should use two or three monitor files only if you have two graphics cards on board:
see here.

2. - What's the difference between my "Radeon" and "Radeon HD 6570" monitors?
There is not much difference. Use only one file, if you have one card.
If you use two files, you cannot be sure which one the system select - system reads first config file he found.
CMPLENGHT is number of characters, which are compared from the name of monitors BOARDNAME, if there is more than one monitor files, i.e.:
if BOARDNAME="Radeon HD 6570"
CMPLENGTH=6 .... for comparison is used only string "Radeon"
CMPLENGTH=12 .... for comparison is used only string "Radeon HD 65" , etc...

3. - What's "Board 0"? Where does it get that from?
In past there were real monitor names ( BOARDNAME) in screenmode settings.
In later versions, there is no names, but
Board0 for first graphics card, Board1 for second one.
So Board0 is screen resolution on your primary graphics card.


P.S. this way it works in case of one graphics card + one monitor.
With case one graphics card + more monitors I have no experiences, you shoud try.
In real, I have connected four or more computers to every monitor on table and have no space for experiments with more monitors.

@afxgroup
OOPS!

I will glad send you PM, but I am afraid that something is wrong.
If I click your name, it not opens your profile with "send message" button, but it opens MY profile, with message:
"Sorry, you don't have the permission to access this area."

PM to other users normally works.
May I contact you via Amigasoft.net contact form?
Or please try send me PM, if it works...

thx

finally, I managed send PM via outbox section...

Hi,

I am looking for Pegasos 2 G4 CPU card.

Card can be both working or not working.
Also can be whole motherboard.

Hi,
I know, that advertisements are uncommon there, but maybe somebody have somewhere in the box.

I am looking for this CPU cards for AmigaOne XE or Micro A1-C:
- G4
- G3 750GX

Cards can be both working or not working.
Also can be whole motherboard.

put in autoexec.cfg this line:
seta r_renderer "GLSL"

or if you want, change the line with "seta r_renderer ARB2" in default.cfg

@rjd324

On previous versions with renderer ARB2 there was normal that screen resolution has no influence to FPS.
I am not tested ARB2 with last version, only GLSL and there is difference in FPS, but not big. ( +2 FPS: 1920x1080->800x600 )

And regarding the configuration:
With some of old versions ( sorry, I an not know which version exactly ) .cfg in /base directory works also for timedemo, and .cfg from /demo was ignored.
I will try how it works with latest version.

And allways is better not to change default.cfg, but add new file autoexec.cfg to the same directory.
And in autoexec.cfg put only lines with changes, for example only line: seta r_renderer "GLSL"

@SinanSam460
try diff this log with output from PreRelease Beta5, maybe you find something interesting.

Dhewm3 V1.5.5 Timedemo:

AmigaOne X1000+HD 7970:
800x600, All advanced options disabled, GLSL renderer, seta r_speedHackShadow "2.0" = 33.5 FPS
1920x1080, All advanced options disabled, GLSL renderer, seta r_speedHackShadow "2.0" = 31.4 FPS
1920x1080, All advanced options disabled, GLSL renderer, seta r_speedHackShadow "1.033" = 24.4 FPS
1920x1080, advanced options enabled + no antialiasing, GLSL renderer, seta r_speedHackShadow "1.033" = 11.2 FPS

800x600, advanced options enabled + no antialiasing, GLSL renderer, seta r_speedHackShadow "2.0" = 18 FPS

On X1000 perfectly playable.


Sam440ep-flex+R9 270X:
733 MHz, 800x600, All advanced options disabled, ARB renderer = 4.8 FPS
Hyperclock to 766 MHz: 5.0 FPS
Playable with certain patience

@walkero + others
many thanks for tips.

I just now registered MUI, so I upgrade it to 5.0.
I also check other enhancements - but I have no RTG, only AGA + Indivision with 800 x 600 resolution.

Hi,
after 20 years with NG machines only I again purchased classic: A1200.
My configuration is A1200 + Indivision AGA + ACA1234 030/50 + FPU/50.

And I have question regarding MUI:

- last classic version I found is MUI3.8.
- what else except MUI I need to have a nice look of Workbench? Do you have some tips? MagicWB looks too historical today.
I had it 20 years before, but looking for something nicer

- what about MUI 5.0? Is it usable on my configuration or is it slow?
@walkero: I read somewhere you use MUI 5.0 on classic, do you have some experiences?

thanks!

@A-EON:

And what about Enhancer 2 - Basic ? Or Enhancer Utilities ?

I.e. full Enhancer without Warp3DNova, RadeonHD, RadeonRX, OGLES,
but with all other commodities, utilities, SFS2, libraries, commands and tools.

Why?

I have two full enhancers - for AmigaOne X1000 and Sam440ep-flex. I am using here modern PCIe graphics cards and I am satisfied.

But I have also this computers without Enhancer:
- AmigaOne XE - PCIe works, but last RadeonHD versions are probably not tested with XE and is a far less compatible than earlier versions,
- Sam440ep - PCIe works, but little Sam is very slow for this,
- MicroA1-C and Pegasos2 - cannot use PCIe cards.

I want also enjoy all Enhancer software except graphics on my older Amigas.
I don't want to copy this files from my X1000, and standart release of Enhancer is too expensive - I suppose that biggest expenses are development of graphics drivers which I not need.

If there is possibility of purchase Basic ( without enhanced graphics ) version, it will be great for me. And maybe it attract also others. And it will be additional small ammount for developers.
