[dpdk-dev] [PATCH v2] cpu_layout.py: adjust output format to align

[dpdk-dev] [PATCH v2] cpu_layout.py: adjust output format to align

[Shannon Zhao]

Bug: when "core id" is greater than 9, the cpu_layout.py output doesn't align.

        Socket 0        Socket 1
        ---------       ---------
Core 9  [4, 16]         [10, 22]

Core 10         [5, 17]         [11, 23]

Solution: adjust output format to align based on the maximum length of the "core id" and "processor"

        Socket 0        Socket 1
        ---------       ---------
Core 9  [4, 16]         [10, 22]

Core 10 [5, 17]         [11, 23]

Hi Shannon,

I feel this version is better but it's really complicated to read.

This line is not indented as the other ones.

Could you replace all these numbers by something meaningful and easier to 
understand?
Example: 5 can be replaced by len('Core ')

Other comment: please add spaces around operators (= + - *).

Thanks

Hi Thomas,

Thanks for your advice.
I'll modify the patch and send it as 'patch v3' later.

[dpdk-dev] [PATCH v3] cpu_layout.py: adjust output format to align

Bug: when "core id" is greater than 9, the cpu_layout.py output doesn't align.

Solution: adjust output format to align based on the maximum length of the "core id" and "processor"

        Socket 0        Socket 1
