Subject: Re: [dpdk-dev] [PATCH v4 0/5] Clean up pci uio implementations
Date: Tue, 19 May 2015 14:57:47 +0900	[thread overview]
Message-ID: <555AD0DB.4000904@igel.co.jp> (raw)
In-Reply-To: <1432014898-3543-1-git-send-email-mukawa@igel.co.jp>

Hi Bernard,


I've updated the series, because I've found the issue in BSD code.
Also, I have rebased the series for latest master branch.

Could you please read my below comments?

pci_uio_map_resource() {
         ....snip....
-       for (i = 0; i < map_idx; i++)
-               rte_free(maps[i].path);
         ....snip....
}

I removed above code from BSD, because 'maps[i].path' will not be
allocated in BSD code.

struct mapped_pci_resource {
        .....snip.....
        char path[PATH_MAX];
        .....snip.....
 };

I left 'path' member like above. It will be used by BSD code even after
BSD support port hotplug function.

Regards,
Tetsuya
