[dpdk-dev] [PATCH 1/2] config/arm: fix Hisilicon kunpeng920 SoC build

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Because of the '9ca2f16' have merged, the current hns3
pmd driver can not be directly complied on the kunpeng920
server board. Therefore, we need to fix the meson build.
Besides, add kunpeng 920 SoC meson cross compile target.

Fixes: 9ca2f16faa7f ("config/arm: isolate generic build")

Why do you think this patch is fixing the one above?
It looks just a new config, not a fix. Am I missing something?

I'm sorry to see you so late. In the meantime, we are celebrating the 
Spring Festival. This patch fixes the problem. If the patch is not 
added, the latest version cannot be directly compiled on the Kunpeng 930 
server board.In addition, the cross compilation configuration file is added.

Please can you explain what was removed which breaks your compilation?

I understand that implementation_id is identified in 9ca2f16. If the 
configuration file does not contain implementation_id, it will be 
displayed as unsupported.

The error as follows:
config/arm/meson.build:227:2: ERROR: Problem encountered: Unsupported 
Arm implementer: 0x48. Please add support for it or use the generic 
(-Dmachine=generic) build.

Besides, we use the -Dmachine=generic, the bug is not resolved.

  meson build or meson -Dmachine=generic build

What is the result of a generic build?

I can explain what's changed and why we changed it.

The previous behavior was that when an uknown implementer was found (when we're building on an uknown build machine) we fell back to a generic build.
The current behavior is we raise an error when building on an unknown build machine and inform the user about the generic build (there's an error in the message, it should be -Dmachine=default instead of -Dmachine=generic). Lijun came across this scenario, so he wants to add an implementer, but it is not a fix, rather an addition that we wanted to encourage when we changed the behavior. The change in behavior also has an additional benefit in that it notifies the user that meson is not doing a tailored build for the build machine and the only permissible build is the generic one.

There were already many fixes for that rework.
Please check if there are other missing updates.

This is actually the first mistake that my testing missed. I tested that the message is properly emitted, but I didn't test the message after we extracted the default->generic rename patch. As a side note, we could address this issue with http://patches.dpdk.org/project/dpdk/patch/1613657555-17683-1-git-send-email-juraj.linkes@pantheon.tech/ - then we can leave the message in place as is (with -Dmachine=generic).

I went through all of the patches again but I didn't find anything that needs addressing.

As far as I'm aware, there were two other fixes for the series. One was a failure of communication (the native margs fix - I implemented what we thought we agreed on) and the other is not really a fix, just the addition of one implementer configuration (I removed the implementer because we didn't have its configuration). The clang cross-compile fixes are related, but those are the problem with that series, not the rework series.

[dpdk-dev] [PATCH 2/2] config/arm: fix Hisilicon kunpeng930 Soc build

[Lijun Ou]

From: Chengchang Tang <tangchengchang@huawei.com>

Because of the '9ca2f16' have merged, the current hns3
pmd driver can not be directly complied on the kunpeng930
FPGA board. Therefore, we need to fix the meson build.
Besides, add kunpeng 930 SoC meson cross compile target.

Fixes: 9ca2f16faa7f ("config/arm: isolate generic build")

Just want to double check.
One Kunpeng920 box I can access have cache line size 64B.

Got it. 
I think RTE_CACHE_LINE_SIZE is not defined for a certain level of cache.
Data can be prefetched into any level of cache by using different APIs.

There was no Kunpeng920 specific config before change 91c730fd4e09.
It would fall back to generic build because the behavior was to do generic build for unknown implementor / part number.

What should we do with this patch? This is because we cannot compile on

I see the need to add config for Kunpeng 920.
IMO, the commit message can be refined.
