[Automated RedPill Loader (ARPL)]

in ESXi you cannot use a virtual usb, you have to choose a virtual hdd (satadom implementation) or a real usb in passthough, i have to check if it's a viable solution.

Was going trough this thread since I didn't know about this flavor of loader and had to give info for this.

 

In ESXi 7 it is actually possible to have virtual USB in VM and it is possible to boot DSM from it. This is how I run DS918 on it, but there are some limitation like not being able to work with any image which has 3.x kernel.

So here is what works for me:

1. Add USB 3 controller to VM
2. UEFI Bios has to be used
   Edit Settings => VM Options => Boot Options
   Frimware: EFI
   Enable UEFI secure boot: uncheck
3. Edit Settings => VM Options => Advanced in the option Configuration Parameters: Edit Configuration and then add
   usb_xhci:3.present = "TRUE"
   usb_xhci:3.deviceType = "disk"
   usb_xhci:3.fileName = "/path/to/tinycore-redpill-uefi.vmdk"
   usb_xhci:3.readonly = "FALSE"
4. You need to use UEFI loader immage and correct vid pid for ESXi has to be set in loader:
   vid=0x0e0f
   pid=0x0005
5. Don't forget to set correct mac and serial, generate with loader serial and mac and then set those in VM config

You also need to convert loader image from raw to vmdk you can use StarWind V2V for this or simply create file tinycore-redpill-uefi.vmdk with following content:

# Disk DescriptorFile
version=1
CID=0d1377b4
parentCID=ffffffff
createType="vmfs"

# Extent description
RW 2097152 VMFS "tinycore-redpill-uefi.img" 0

# The Disk Data Base
#DDB

ddb.adapterType = "lsilogic"
ddb.geometry.cylinders = "131"
ddb.geometry.heads = "255"
ddb.geometry.sectors = "63"
ddb.uuid = "13 9e c3 cf c3 cf 86 0b-a1 90 b9 72 04 b0 91 7e"
ddb.virtualHWVersion = "4"

and put loader image in the same folder as this vmdk, loader has to be named tinycore-redpill-uefi.img

 

When you set it up like this you can use USB boot for DS918.

For reference this is how user config looks like:

{
  "extra_cmdline": {
    "vid": "0x0e0f",
    "pid": "0x0005",
    "sn": "<SERIALNR>",
    "mac1": "<mac1>",
    "mac2": "<mac2>"
  },
  "synoinfo": {
	  "netif_num" : "2"
  },
  "ramdisk_copy": {}
}

 

On Proxmox virtual usb boot can be done by following these steps:

1. Upload tinycore-redpill-uefi.img to proxmox in folder /var/lib/vz/images/
2. Set your VM bios to OVMF (UEFI)
3. Add following to vm config (ie /etc/pve/qemu-server/100.conf)
   args: -device 'qemu-xhci,addr=0x18' -drive 'id=my_usb_disk,file=/var/lib/vz/images/ tinycore-redpill-uefi.img,if=none,format=raw' -device 'usb-storage,id=my_usb_disk,drive=my_usb_disk,bootindex=5'
4. Correct vid pid has to be set for proxmox
vid: 0x46f4
pid: 0x0001
5. Don't forget to set correct mac and serial, generate with loader serial and mac and then set those in VM config

For reference VM config (100.conf) would look something like this:

args: -device 'qemu-xhci,addr=0x18' -drive 'id=my_usb_disk,file=/var/lib/vz/images/tinycore-redpill-uefi.img,if=none,format=raw' -device 'usb-storage,id=my_usb_disk,drive=my_usb_disk,bootindex=5'

[Drivers extension for RedPill - request for comments & drivers packages]

On 2/27/2022 at 6:33 PM, IG-88 said:

this is a test driver for intel gpu's up to 12th gen - at least when it comes to using the pci id of it

the driver is still the one that comes with synology's kernel and as used in 918+/920+

instead of patching one or two id's this is a driver build from source containing all of them (taken from kernel 5.17 rc4)

syno's driver only contains code up to canon lake

i treated all comet lake gpu's as coffee lake and anything above that as canon lake

as i have no newer cpu i can't test this, in theory its should at least bring what was working with the patched driver in 6.2.3 back to life in 7.0

as its only the i915.ko file (and the firmware files)  and not extension for the rp-loader its only meant for people who can freely test, screw up there system and recover or delete and reinstall new

if the driver is copied to /lib/modules and replaces the original driver, fimrware has its own folder in /lib/ (structure in the zip as guidance)

it can happen that the system does not boot anymore (worst case scenario), you would need to delete the file manually and if dsm does not start anymore you would need to mount the system partition(s) of all disks as raid1 to remove the file again

so its meant to be used as testing with a fresh usb and a fresh disk and its meant to be thrown away after testing it

 

!!! its in the developer section on purpose !!! if you screw up your system and can't recover by yourself then i'm not going to help in any way

delete the partitions on you test disk or recover system with this https://xpenology.com/forum/topic/7004-tutorial-how-to-access-dsms-data-system-partitions/

if it works (not worst case) then the system comes up again after a reboot and there should be devices in /dev/dri/, if not it did not work, you should check /var/log/dmesg in that case and check that you replaced the i915.ko properly in /lib/modules/ and also added the firmware in /lib/firmware/i915/

 

 

the way it might be used later would be as a extension in rp-loader so if its added and fails is can be removed again by removing the extension from the loader

(but i have not talked to @pocopico if thats a way to use it in tinycore)

atm its just to play around and to get some feedback about newer gpu's like 10th/11th/12th, newer means more likely not to work but we dont know if we dont  try

 

i915_universal_918p_DSM7.zip
https://usersdrive.com/jbm5bdrnzzi8.html

 

the attached file is the patch used for synology's kernel source include, so if anyone wants to make its own driver or experiment with changing id's ...

the code has plenty of comment about the pci id's and the cpu type (as long as you understand intels shorts for the gen's like CNL, EHL, JSL TGL, ...)

 

i915_pciids.h.patch 6.02 kB · 12 downloads

No luck with this driver. I use ESXi 7 with pci pass-through of UHD Graphics 630. VM crashes the second I insmod this driver, first time I tried it on daily VM by replacing original driver 🤦‍♂️. Had to recover VM by accessing system partition and returning original driver, but lost all the settings carried over after migration from 6.2.3 and had to reinstall DSM7.

 

Here is log from test VM once I unload original and insmod this universal driver.

[  699.806459] Fixing recursive fault but reboot is needed!

 

Patched driver for 6.2.3 was working great, so I tried to do the same thing here and it was working, well at least /dev/dri/... stuf gets created didn't try transcoding yet. What I did was change original pid:vid 8086:3E92 to 8086:9BC8 and removed module signature. If someone is brave enough to try module is attached.

[RedPill - the new loader for 6.2.4 - Discussion]

Just as a reminder it is possible to boot virtual usb disk in ESXi, here is the description how install-dsm-62x-on-esxi-6770-as-baremetal. However it works only for EFI boot which juns loader for 918 supported.
