meta-ampere: Support software workaround for PSU redundancy issue

When system only uses single PSU ( ex : PSU1 ) to power ON normal 12V,
HSC2 will be trigged Fault event (FET health).
At this time, plugging in PSU2 in system, the PSU2 won't deliver power to
+12V_MB because HSC2 is protected by Fault event.
Due to HSC2 protected, the PSU redundancy mechanism can't be created.
Once PSU1 is plugged out at this moment, system will crash ( reset )
because +12V_MB dropped.
Support detecting PSU plug event and reset the Hot-Swap feature by
disabling and then enabling again it through PMBUS command to clear the
event.

Tested:
1. Plug only PSU1 to power ON system (12V)
2. Wait until host is booted, check POUT:
    $ ipmitool  sdr | grep "POUT"
    PSU1_POUT        | 112 Watts         | ok
    PSU2_POUT        | 0 Watts           | ok
3. Plug in PSU2 in system, check POUT:
   $ ipmitool sdr | grep "POUT"
   PSU1_POUT        | 64 Watts          | ok
   PSU2_POUT        | 48 Watts          | ok
4. Unplug AC power PSU1, check POUT:
   $ ipmitool sdr | grep "POUT"
   PSU1_POUT        | 0 Watts           | ok
   PSU2_POUT        | 128 Watts         | ok
5. Plug in AC power PSU1, check POUT:
   $ ipmitool sdr | grep "POUT"
   PSU1_POUT        | 80 Watts          | ok
   PSU2_POUT        | 64 Watts          | ok
6. Repeat 1. to 5. with PSU2.

OpenBMC

Build Status

OpenBMC is a Linux distribution for management controllers used in devices such as servers, top of rack switches or RAID appliances. It uses Yocto, OpenEmbedded, systemd, and D-Bus to allow easy customization for your platform.

Setting up your OpenBMC project

1) Prerequisite

  • Ubuntu 14.04
sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat
  • Fedora 28
sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake \
    rpcgen perl-Thread-Queue perl-bignum perl-Crypt-OpenSSL-Bignum
sudo dnf groupinstall "C Development Tools and Libraries"

2) Download the source

git clone git@github.com:openbmc/openbmc.git
cd openbmc

3) Target your hardware

Any build requires an environment set up according to your hardware target. There is a special script in the root of this repository that can be used to configure the environment as needed. The script is called setup and takes the name of your hardware target as an argument.

The script needs to be sourced while in the top directory of the OpenBMC repository clone, and, if run without arguments, will display the list of supported hardware targets, see the following example:

$ . setup <machine> [build_dir]
Target machine must be specified. Use one of:

centriq2400-rep         f0b                     fp5280g2
gsj                     hr630                   hr855xg2
lanyang                 mihawk                  msn
neptune                 nicole                  olympus
olympus-nuvoton         on5263m5                p10bmc
palmetto                qemuarm                 quanta-q71l
romulus                 s2600wf                 stardragon4800-rep2
swift                   tiogapass               vesnin
witherspoon             witherspoon-tacoma      yosemitev2
zaius

Once you know the target (e.g. romulus), source the setup script as follows:

. setup romulus

For evb-ast2500, please use the below command to specify the machine config, because the machine in meta-aspeed layer is in a BSP layer and does not build the openbmc image.

TEMPLATECONF=meta-evb/meta-evb-aspeed/meta-evb-ast2500/conf . openbmc-env

4) Build

bitbake obmc-phosphor-image

Additional details can be found in the docs repository.

OpenBMC Development

The OpenBMC community maintains a set of tutorials new users can go through to get up to speed on OpenBMC development out here

Build Validation and Testing

Commits submitted by members of the OpenBMC GitHub community are compiled and tested via our Jenkins server. Commits are run through two levels of testing. At the repository level the makefile make check directive is run. At the system level, the commit is built into a firmware image and run with an arm-softmmu QEMU model against a barrage of CI tests.

Commits submitted by non-members do not automatically proceed through CI testing. After visual inspection of the commit, a CI run can be manually performed by the reviewer.

Automated testing against the QEMU model along with supported systems are performed. The OpenBMC project uses the Robot Framework for all automation. Our complete test repository can be found here.

Submitting Patches

Support of additional hardware and software packages is always welcome. Please follow the contributing guidelines when making a submission. It is expected that contributions contain test cases.

Bug Reporting

Issues are managed on GitHub. It is recommended you search through the issues before opening a new one.

Questions

First, please do a search on the internet. There's a good chance your question has already been asked.

For general questions, please use the openbmc tag on Stack Overflow. Please review the discussion on Stack Overflow licensing before posting any code.
