Add xilinx a72 and a78 #252

bentheredonethat · 2023-09-11T23:17:25Z

Add support for xilinx platforms cortex a72 on Versal, cortex a78 on versal-net

both of these have support for standalone and baremetal

Hi @arnopo the failed check is due to Xilinx BSP. The failures are present in other platforms too.

We need the routines as part of enabling Xilinx BSP for these platforms.

Thanks,
Ben

Hi @bentheredonethat,

Hi @arnopo the failed check is due to Xilinx BSP. The failures are present in other platforms too.

I can see two issues in CI one is linked to the format of one of your patch, the second is linked to the Zephyr CI, that I just fixed.

We need the routines as part of enabling Xilinx BSP for these platforms.

Thanks, Ben

@arnopo ok i can update commit message due to warning
"1: UC5 Title exceeds max length (98>72): "lib: generic: zynqmp_a78: Add support for versal_net a78 platform with System Device Tree workflow"

was there anything else?

bentheredonethat · 2023-09-12T14:56:27Z

@arnopo fixed the commit message issue

@arnopo,
How did you handle this for the existing files like apps/system/generic/machine/zynqmp_r5/helper.c in your initial integration with checkpatch?

I could argue that checking for CamelCase in the platform-specific code is wrong in that this code may have to call down into BSP-specific code that may have a very different set of coding conventions.

I did not handle the exception, it could become difficult to manage.
For me, failing the test but with a justification is acceptable.

@tnmysh to be clear - is the only gap to fix right now the metal-io-mem-map() part? the cache part there is already convention of other platforms.

if so i will work on updating Xilinx BSP and then update the PR with that accordingly.

tnmysh · 2023-10-11T15:12:42Z

@arnopo we have refactored Xilinx platform specific files and added new platform support accordingly in this PR. I think it's ready to be merged, we can have this one as part of this release.

Do you have any extra comments? I see some failures with checkpatch. camelCasing can't be fixed. Other than that this PR looks good to me.

tnmysh

LGTM.

Hi @arnopo i just pushed another version. i testd zynq, zynqmp-a53 and zynqmp-r5 for freertos and generic. all of these passed.

That being said, if you will do not want the sys.c/sys.h xilinx common code consolidated i am fine with that.

arnopo

Just a minor clean-up to address, else LGTM

bentheredonethat · 2023-10-13T15:46:03Z

Hi @arnopo on my end there is a lot of testing to cover. I would ask that this not be included in the upcoming release.

Thanks
CC @tnmysh

tnmysh · 2023-10-13T15:49:51Z

@arnopo I removed my ACK till Ben confirms this is working.
We can exclude this commit from this release and merge it later.

bentheredonethat · 2023-10-13T22:37:45Z

@arnopo i did testing for builds of apps and demos that use libmetal for xilinx paltforms. im ok t to proceed now
CC @tnmysh

tnmysh

This patch removes almost 1000 lines (~400 line of code) from libmetal library and we can achieve same platform support.

Thanks @bentheredonethat for efforts. When your side testing is done please let us know.
This will be good addition to release.

bentheredonethat · 2023-10-14T14:08:06Z

im ok with testing on my side

arnopo · 2023-10-16T08:40:36Z

@bentheredonethat
Please, could you rebase it on top of main branch that fixes CI test

@tnmysh : then ok to merge?

bentheredonethat · 2023-10-16T14:11:31Z

@arnopo i woke up sick today.. will try to do today. otherwise will hopefully do tomorrow

tnmysh · 2023-10-16T17:46:38Z

@bentheredonethat Please, could you rebase it on top of main branch that fixes CI test

@tnmysh : then ok to merge?

Yes I am ok to merge.

Move common code in Xilinx area to consolidated location to remove redundant code. Enable A72 and A78 build in Standalone BSP. lib: generic: Add support for a78 with System Device Tree flow System Device Tree workflow is AMD-Xilinx workflow whereby the BSP, libraries and applications in software are derived from a hardware-design. The hardware-design is used to generate a system device tree (SDT) that describes information for Linux and other processing environments. The xreg/xcpu files are not generated for SDT workflow. Because of this do not include if SDT symbol is present in BSP. Signed-off-by: Ben Levinsky <ben.levinsky@amd.com>
