Subject: [PATCH] axs103: Clean-up smp_kick_all_cpus()
|
||||
|
||||
* Rely on default pulse polarity value
|
||||
* Don't mess with "multicore" value as it doesn't affect execution
|
||||
|
||||
In essence we now do a bare minimal stuff:
|
||||
1) Select HS38x2_1 with CORE_SEL=1 bits
|
||||
2) Select "manual" core start (via CREG) with START_MODE=0
|
||||
3) Generate cpu_start pulse with START=1

Subject: [PATCH] axs103: Support slave core kick-start on axs103 v1.1
|
||||
firmware
|
||||
|
||||
In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit
|
||||
compared to previous implementation.
|
||||
|
||||
In particular:
|
||||
* We used to have a generic START bit for all cores selected by CORE_SEL
|
||||
mask. But now we don't touch CORE_SEL at all because we have a dedicated
|
||||
START bit for each core:
|
||||
bit 0: Core 0 (master)
|
||||
bit 1: Core 1 (slave)
|
||||
* Now there's no need to select "manual" mode of core start
|
||||
|
||||
Additional challenge for us is how to tell which axs103 firmware we're
|
||||
dealing with. For now we'll rely on ARC core version which was bumped
|
||||
from 2.1c to 3.0.

Synopsys VDK Software Development Platform
|
||||
|
||||
Intro
|
||||
=====
|
||||
|
||||
The Virtualizer Development Kit (VDK) Family for ARM Cortex Products
|
||||
consists of a set of virtual prototypes that provide a virtualizer for
|
||||
the ARM core variants. The VDK is a standalone package that runs on an
|
||||
host computer.
|
||||
|
||||
Buildroot will generate the kernel image and a minimal root filesystem.
|
||||
|
||||
How to build it
|
||||
===============
|
||||
|
||||
Configure Buildroot
|
||||
-------------------
|
||||
|
||||
Configuring Buildroot is pretty simple, just execute:
|
||||
|
||||
$ make snps_aarch64_vdk_defconfig
|
||||
|
||||
Build the rootfs and kernel
|
||||
---------------------------
|
||||
|
||||
Note: you will need to have access to the network, since Buildroot will
|
||||
download the packages' sources.
|
||||
|
||||
You may now build your rootfs with:
|
||||
|
||||
$ make
|
||||
|
||||
(This may take a while)
|
||||
|
||||
Result of the build
|
||||
-------------------
|
||||
|
||||
After building, you should obtain this tree:
|
||||
|
||||
output/images/
|
||||
-- rootfs.ext2
|
||||
-- Image
|
||||
|
||||
Installing your rootfs and Image
|
||||
================================
|
||||
|
||||
Now copy the content of the output/images folder to the VDK' skins
|
||||
folder:
|
||||
|
||||
$ cp rootfs.ext2 Image <vdk_installation_path>/skins/Vanilla-Cortex/ARMv8
|
||||
|
||||
|
||||
Starting the VDK
|
||||
================================
|
||||
|
||||
Go the VDK' installation root and execute the 'start' script:
|
||||
|
||||
$ cd <vdk_installation_path>
|
||||
$ ./start.sh
|
||||
|
||||
The VP Explorer application will be executed, starting the simulation
|
||||
automatically.
|
||||
|
||||
