Help regarding Building x86_64 BSP

2023-03-07 Thread Siddharth Khattar

Hello all,
So I was aiming to make a project to improve the amd64 BSP for RTEMS
(modify it according to ACPI standards along with other stuff) but first I
would need to build it. Unfortunately there was no way to build it natively
within RTEMS source. So, I needed to install QEMU and had to build the UEFI
firmware,OVMF by Tianocore in order to build it. Unfortunately, I am stuck
on this step as building edk2 on Ubuntu 22.04 is causing problems as with
the gcc version. To be exact, with the use of variable length arrays (VLAs)
in the code. Starting with GCC version 8.0, VLA's are not supported by
default and generate warnings or errors when used.

 An alternate path would be to use docker and build it using Stuart within
that. And the last possible option would be to build it through a Ubuntu
18.0 VM. I was wondering if anyone in the community has knowledge regarding
the x86_64 BSP for RTEMS would be able to guide me with this? as the docs
regarding this (9.18) are a few years old and are not completely up-to-date.

Thanking you for your time,
Siddharth Khattar

Indeed, they still list Ubutnu 16.04 LTS as a build OS. Hmm, I would go 
with VM for this. You need to build it just once...

Investigating more, it looks like qemu build those too, so there is no 
need to deal with TianoCore alone anymore. My 7.2.0 install contains:


$ find qemu-7.2.0/share/qemu/ -name 'edk2*'
qemu-7.2.0/share/qemu/edk2-arm-code.fd
qemu-7.2.0/share/qemu/edk2-x86_64-code.fd

qemu-7.2.0/share/qemu/edk2-licenses.txt

Ditto for Qemu build by RSB. Will send you tarball of scripts I'm using

Did you build the x86_64 tools and qemu using the RTEMS Source Builder?

Call for Mentors gsoc'23

2023-03-07 Thread Gedare Bloom

Hello all,

RTEMS Project is again to participate in GSoC (2023). If you would
like to be a primary or secondary mentor, please register at
https://summerofcode.withgoogle.com/ for the current program year, and
then let me know so that I can add you to RTEMS Project. The workflow
is a bit different this year, as I cannot add/invite individuals until
they have set up their profile and agreed to the terms and conditions
for the current year's program.

If you have ideas for small/large projects, feel free to add them as
tickets, as explained on our ideas page:
https://devel.rtems.org/wiki/Developer/OpenProjects

There have already been a few potential new contributors on the
Discord and mailing list.

Thanks,
Gedare

Re: [PATCH 0/1] GSOC Contributor Opportunity

2023-03-07 Thread Gedare Bloom

Hi Ruturaj,

It helps if you can describe briefly the topics that interest you,
especially one email per topic idea can be most fruitful. That will
give you more likely feedback, because most of us have no clue what
the ticket numbers mean without clicking through. It would also be a
good idea to hop on the Discord and discuss the topic ideas of
interest in the #gsoc channel.

Two of those tickets relate to the build system and tooling. Chris may
know if they're still of interest.
