Subject: Re: [dpdk-dev] [PATCH] cpu_layout.py: adjust output format to align
Date: Wed, 28 May 2014 11:02:36 +0800	[thread overview]
Message-ID: <538551CC.3000108@huawei.com> (raw)

Hi Thomas,

Thanks for your reply.

I have checked my patch. It doesn't apply correctly when "core id" is greater than 2 characters.

Following is my revised patch. It's based on the maximum length of the "core id" and "processor" to adjust the alignment length.


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

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

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