RE: QEMU for Qualcomm Hexagon - KVM Forum talk and code available

[Taylor Simpson]

That is correct.

Once you register on developer.qualcomm.com, you can download the Hexagon SDK 
version 3.4.3.  Note that there are different downloads for Linux and Windows 
hosts.

Once you have installed the SDK, look for the document bundle in the following 
location
<INSTALL_DIR>/tools/HEXAGON_Tools/8.3.02/Documents/Hexagon_Document_Bundle.pdf
That PDF file is a container for a bunch of other documents.  If you want to 
read more about the Hexagon architecture, look at the following
V67 Programmer's Reference Manual
V66 HVX Programmer's Reference Manual
The version on the quic github implements these.  Note that HVX stands for 
Hexagon Vector eXtensions.  It is an optional set of instructions that operate 
on 128-byte vectors.

IIRC, the revng github implements up to V62.  Alessandro or Niccolo can confirm.

Note that the toolchain in that installation generates code for the standalone 
runtime or the RTOS, not Linux that the quic qemu generates.  However, they 
should run on the revng version.  In the coming weeks, we'll work on setting up 
a container to build the toolchain that will generate binaries that will run on 
the quic version.

If anyone has any more questions, I'm happy to answer them.

Is your target the 'Hexagon Series 600', with documentation available here?
