Using term of VM0 would mislead to a VM with VM id 0 easily, whereas VM id 0 could be used for any PRE_LAUNCHED_VM. So replace VM0 with SOS_VM. Signed-off-by: Victor Sun <victor.sun@intel.com>

What hardware does ACRN support?
|
|
********************************
|
|
|
|
ACRN runs on Intel Apollo Lake and Kaby Lake boards, as documented in
|
|
our :ref:`hardware` documentation.

Clear Linux* OS fails to boot on my NUC
|
|
***************************************
|
|
|
|
If you're following the :ref:`getting_started` documentation and the NUC
|
|
fails to boot, here are some options to try:
|
|
|
|
* Upgrade your platform to the latest BIOS
|
|
* Verify Secure Boot is disabled in the BIOS settings:
|
|
|
|
- Depending on your platform, press for example, :kbd:`F2` while
|
|
booting to enter the BIOS options menu, and verify "Secure Boot" is
|
|
not checked in the "Boot Options"
|
|
* Make sure you are using EFI (and not legacy BIOS)
|
|
|
|
How do I configure ACRN's memory use?
|
|
*************************************
|
|
|
|
It's important that the ACRN Kconfig settings are aligned with the physical memory
|
|
on your platform. Check the documentation for these option settings for
|
|
details:
|
|
|
|
* :option:`CONFIG_PLATFORM_RAM_SIZE`
|
|
* :option:`CONFIG_SOS_RAM_SIZE`
|
|
* :option:`CONFIG_UOS_RAM_SIZE`
|
|
* :option:`CONFIG_HV_RAM_SIZE`
|
|
|
|
For example, if memory is 32G, setup ``PLATFORM_RAM_SIZE`` = 32G
|
|
|
|
::
|
|
|
|
config PLATFORM_RAM_SIZE
|
|
hex "Size of the physical platform RAM"
|
|
default 0x200000000 if PLATFORM_SBL
|
|
default 0x800000000 if PLATFORM_UEFI
|
|
|
|
Setup ``SOS_RAM_SIZE`` = 32G too (The SOS will have the whole resource)
|
|
|
|
::
|
|
|
|
config SOS_RAM_SIZE
|
|
hex "Size of the Service OS (SOS) RAM"
|
|
default 0x200000000 if PLATFORM_SBL
|
|
default 0x800000000 if PLATFORM_UEFI
|
|
|
|
Setup ``UOS_RAM_SIZE`` to what you need, for example, 16G
|
|
|
|
::
|
|
|
|
config UOS_RAM_SIZE
|
|
hex "Size of the User OS (UOS) RAM"
|
|
default 0x100000000 if PLATFORM_SBL
|
|
default 0x400000000 if PLATFORM_UEFI
|
|
|
|
Setup ``HV_RAM_SIZE`` (we will reserve memory for guest EPT paging
|
|
table), if you setup 32G (default 16G), you must enlarge it with
|
|
(32G-16G)/2M pages (where pages are 4K). The example below is after
|
|
HV_RAM_SIZE is changed to 240M
|
|
|
|
::
|
|
|
|
config HV_RAM_SIZE
|
|
hex "Size of the RAM region used by the hypervisor"
|
|
default 0x07800000 if PLATFORM_SBL
|
|
default 0x0f000000 if PLATFORM_UEFI
