Release notes

Release notes describing changes, fixes and known issues in PC Engines apux releases.

OS status

Some operating system have problems running with different storage medias. These table shows currently tested systems on BIOS v4.10.0.x with corresponding medias:

OS	SD card	SATA disk	mSATA disk	USB stick
Voyage	(1)	OK	OK	OK(2)
Debian	OK	OK	OK	OK(2)
OPNSense	OK	OK	OK	OK(2)
pfSense	OK	OK(*)	OK	OK(2)

^* - works well with BIOS v4.6.8 or later in mainline and all legacy releases; for v4.6.7 and older mainline versions issues with installation and system functionality (installation break, unwanted reboots), can be fixed by adding a hint hint.ahci.0.msi="0", for more information see this document

⁽²⁾ - all apu boards have problems with USB 3.x stick detection in BIOS, system is working properly, but after reboot/warmboot/coldboot USB stick may not appear in BIOS boot menu (depends on the stick, well working sticks are mentioned in this document)

⁽¹⁾ - Voyage Linux is bootable on SD card and works well in read-only mode, remounting as read-write and writing changes to SD sometimes results in kernel panic which often leads to non-operable system

Documentation

The list of most useful documents from documentation:

• CPU Boost - document briefly describes what the Core Performance Boost is and how to verify it works in BIOS and operating system.
• Fast Boot - document describing research for Fast Boot path for apu boards. The Fast Boot was intended to restore memory configuration from non-volatile storage and reduce the boot time of the platform. You will find the issues and limitations which did not allow to implement the feature.
• ROCA TPM vulnerability - document describing ROCA TPM vulnerablity status and verification on TPM1a module form PC Engines.
• APU mPCIe capabilities - list of all signals and interfaces present on mPCIe connectors for apu2/3/4 boards. The document also describes possible usage of the slots.
