Installing Ubuntu 18.04.x LTS (Bionic Beaver) on the Lenovo ThinkPad E585

Make sure to update your FIRMWARE of your laptop.

Lenovo E585 support website

Firmware updates can be done with an USB flash drive.

Get Ubuntu 18.04.x LTS.

Ubuntu 18.04.2 LTS (Bionic Beaver)

Use Etcher or Rufus to make a bootable iso.

BalenaEtcher For Linux, MacOS and Windows.

Rufus For Windows only.

Installing Ubuntu

After inserting USB flash drive and turning on your laptop make sure to press F12 during boot and select your USB flash drive or Ubuntu installation.
make sure to hold or press SHIFT a couple of times to enter the GRUB menu.
Highlight "Installing Ubuntu"
Press the "e" key on your keyboard to edit.
add without quotes "ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 clocksource=hpet libata.force=1:nohrst iommu=pt" to the list.

setparams 'Try Ubuntu without Installing'

    initrd        /casper/initrd

Press F10 to start the installation of Ubuntu.

Configuring GRUB

Open your terminal with the keys CTRL + ALT + T and do the following:

sudo nano /etc/default/grub

Add GRUB_CMDLINE_LINUX="ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 clocksource=hpet libata.force=1:nohrst iommu=pt"
It should look like this
$ sudo cat /usr/share/grub/default/grub

If you change this file, run 'update-grub' afterwards to update

/boot/grub/grub.cfg.

For full documentation of the options in this file, see:

info -f grub -n 'Simple configuration'

GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=lsb_release -i -s 2> /dev/null || echo Debian GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="ivrs_ioapic[32]=00:14.0 ivrs_ioapic[33]=00:00.1 clocksource=hpet libata.force=1:nohrst iommu=pt"

Uncomment to enable BadRAM filtering, modify to suit your needs

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

GRUB_BADRAM="0x01234567,0xfefefefe, 0x89abcdef,0xefefefef"
Press CTRL + O to save and CTRL + X to exit.
Update GRUB with:
```
sudo update-grub
```

Done

Quote from eazrael on https://evilazrael.de/comment/914

Ok, this is really a firmware bug, the ACPI IVRS table lacks at least one entry. Adding ivrs_ioapic[32]=00:14.0 instead of intremap=off is sufficient to make the system boot until Lenovo releases an UEFI update with a working IVRS table. At least UEFI 1.27 (2018-07-24) needs this override. And spec_store_bypass_disable=prctl is still needed for Ubuntu & co.

The clue is the line "[Firmware Bug]: AMD-Vi: IOAPIC[32] not in IVRS table". I decompiled the ACPI tables, started to read the AMD documentation, but in the end I just guessed the 32 from the error message and 00:14.0 from the lspci output and the Stack Overflow/Ubuntu forum entries. Interesting stuff, but too much to read in my little time.

What was helpful is the Linux boot parameter amd_iommu_dump=1 which will dump information from the IVRS table:

[    0.851042] AMD-Vi: Using IVHD type 0x11
[    0.851401] AMD-Vi: device: 00:00.2 cap: 0040 seg: 0 flags: b0 info 0000

[    0.851871] AMD-Vi:   DEV_RANGE_END           devid: ff:1f.7
[    0.851875] AMD-Vi:   DEV_SPECIAL(HPET[0])           devid: 00:14.0
[    0.851876] AMD-Vi:   DEV_SPECIAL(IOAPIC[33])                devid: 00:14.0
[    0.851877] AMD-Vi:   DEV_SPECIAL(IOAPIC[34])                devid: 00:00.1
[    1.171028] AMD-Vi: IOMMU performance counters supported

Resolving devid 00:14.0 was easy via lspci:

00:14.0 SMBus: Advanced Micro Devices, Inc. [AMD] FCH SMBus Controller (rev 61) but for 00:00.1 I have not found the device. If anybody knows how to list all device ids and their associate devices/drivers/etc, please mail me.

ivrs_ioapic: correction IOMMU Adresses in BIOS.

libata.force: No hardware reset on the SATA controller. So that the computer wakes up after suspend to ram.

iommu=pt: pass through for iommu, without this option, X does not seem to work Kernel 4.20.0.

Installing Manjaro

After inserting USB flash drive and turning on your laptop make sure to press F12 during boot and select your USB flash drive or Ubuntu installation.
make sure to hold or press SHIFT a couple of times to enter the GRUB menu.
Highlight "Installing Boot: Manjaro.x86_64"
Press the "E" key on your keyboard to edit.
add without quotes "iommu=soft" to the list.

Set arguments above with editor

    linux /boot/vmlinuz-$2
    initrd /boot/amd_ucode.img /boot/intel_ucode.img /boot/initramsfs-x86_64.img iommu=soft

Press F10 to boot Manjaro.

sudo nano /etc/default/grub

Add GRUB_CMDLINE_LINUX="iommu=soft"

Press CTRL + O to save and CTRL + X to exit.
Update GRUB with:
```
sudo update-grub
```

Explanation about 'iommu=soft'

Quoted from Tim Kennedy at https://unix.stackexchange.com/questions/469153/what-are-the-implication-of-iommu-soft

'iommu=soft' tells the kernel to use a software implementation to remap memory for applications that can't read above the 4GB limit.

The kernel documentation for these options is here: https://github.com/spotify/linux/blob/master/Documentation/x86/x86_64/boot-options.txt#L207

What's preferable is a solution that satisfies your expectations for performance, system temperature, battery life, etc, etc. If iommu=soft give you satisfactory performance, temperature, and battery life, then I would say go with that.
